0:04
is episode number nine. Today's question, why does
0:07
anything exist?
0:13
Why is there something rather
0:13
than nothing? This has been
0:17
called the first question we
0:17
have any right to ask. In
0:20
today's episode, we will review
0:20
the latest theories and evidence
0:24
which may have finally settled
0:24
this mystery. Enjoy.
0:29
Why does anything exist?
0:29
Why is there something rather
0:33
than nothing? Wouldn't nothing
0:33
have been so much easier? This
0:38
question has ordered and
0:38
mystified people throughout
0:41
time. Quote, the first question
0:41
which we have a right to ask
0:47
will be Why is there something
0:47
rather than nothing? Gottfried
0:51
Wilhelm Leibniz in the
0:51
principles of nature and grace
0:55
based on reason 1714.
0:59
Quote, not how the world is, is
0:59
the mystical, but that it is
1:05
Ludwig vidkun Stein in treatise
1:05
on logic and philosophy 1921.
1:11
Quote, no question is more
1:11
sublime than why there is a
1:16
universe why there is something
1:16
rather than nothing. Derek
1:20
parfit in why anything? Why this
1:20
2008
1:28
Martin Heidegger call this
1:28
question the fundamental
1:31
question of metaphysics, but it
1:31
might as well be the fundamental
1:35
question for any being, our
1:35
existence poses a mystery that
1:39
demands an answer. Where does it
1:39
all come from? Why is there
1:44
anything at all? every society
1:44
in every time has wrestled with
1:49
this dilemma. It's our most
1:49
enduring question. For we all
1:53
seek to know why we are here.
1:53
Lacking an answer, we are like a
1:59
ship adrift. Our ignorance on
1:59
this question makes us like an
2:03
amnesiac who awakens in a dark
2:03
and strange place, knowing
2:07
neither where we are nor how we
2:07
got here. Some say without an
2:11
answer to this question, we
2:11
can't know anything. Quote, it
2:17
is possible to think that one
2:17
cannot answer any question if
2:20
one cannot answer the question
2:20
of why there is something rather
2:23
than nothing. How can we know
2:23
why something is or should be a
2:27
certain way? If we don't know
2:27
why there is anything at all?
2:31
Surely this is the first
2:31
philosophical question that has
2:35
to be answered. And quote,
2:35
Robert nozick in philosophical
2:40
explanations 1981.
2:44
With an answer to this question,
2:44
we could orientate ourselves, we
2:48
would know our place in reality,
2:48
and understand the reason behind
2:52
it all. An answer to this
2:52
question would tell us not only
2:56
why we exist, but also what else
2:56
exists both within the universe
3:00
we see and beyond. But can this
3:00
question even be answered? Some
3:06
have suggested the answer is
3:06
unknowable. Quote, who knows
3:11
truly, who here will declare
3:11
whence it arose? whence this
3:16
creation, the gods are
3:16
subsequent to the creation of
3:20
this, who then knows whence it
3:20
has come into being? whence this
3:26
creation has come into being?
3:26
Whether it was made or not he in
3:30
the highest heaven? Is it
3:30
surveyor? Surely he knows, or
3:34
perhaps he knows not? The hymn
3:34
of creation in rigveda, circa
3:40
1500 BC. For most of history, the
3:43
question remains beyond the
3:46
possibility of being answered.
3:46
But we live in a most exciting
3:50
point in time, one where this
3:50
question has fallen to the
3:53
progress of human knowledge. In
3:53
the past decades, results from
3:58
physics, cosmology, mathematics,
3:58
and computer science have
4:03
coordinated at last to solve
4:03
this timeless question. We can
4:08
now say, with some confidence,
4:08
why we exist. The answer we have
4:13
is more than an idle
4:13
philosophical speculation. It
4:16
can be observationally tested
4:16
and thereby be confirmed or
4:19
falsified. So far, observations
4:19
are in agreement with this
4:24
answer. Let us retrace
4:24
humanity's steps in finding this
4:29
answer and see what this answer
4:29
reveals about the nature of
4:32
reality and our place in it. two
4:32
paths to existence. One reason
4:39
we find Why does anything exist
4:39
so difficult is that there are
4:43
only two possible answers. Both
4:43
are repugnant to our intuition
4:47
as each contradicts our common
4:47
sense understanding of the
4:50
world. given something exists
4:50
either one, something emerged
4:57
from nothing or two
5:00
There are self existent
5:00
things. The idea that something
5:04
came out of nothing is contrary
5:04
to reason. How can nothingness
5:09
do nevermind create anything?
5:09
The idea that there exists self
5:14
exists and things is contrary to
5:14
experience. Everything we know
5:19
appears to have a proceeding
5:19
cause How could anything create
5:23
itself or exist without some
5:23
creative act? And yet that one
5:29
of these answers must be writes
5:29
seems inescapable? There's no
5:33
other way to reach something
5:33
exists without either starting
5:37
with something at the beginning,
5:37
or starting with nothing and
5:40
having something emerge from
5:40
nothing? If we seek an answer to
5:44
this question, we have to be
5:44
willing to accept an idea
5:46
contrary to our common sense
5:46
understanding of the world. But
5:51
which of these paths leads to
5:51
the correct answer? something
5:55
from nothing? The first of the
5:55
two answers Is that something
5:59
emerged from nothing. But how is
5:59
this possible, doesn't even make
6:05
sense logically. For at least
6:05
2500 years, humans have debated
6:11
whether anything can come from
6:11
nothing. The Greek philosopher
6:15
power manatees made the earliest
6:15
recorded arguments that nothing
6:18
comes from nothing, quote, I
6:18
will not permit the to say or to
6:24
think that being came from not
6:24
being for it is impossible to
6:28
think or to say that not being
6:28
is what would then have stirred
6:32
it into activity that being
6:32
should arise from not being
6:36
later rather than earlier. So it
6:36
is necessary that being either
6:40
is absolutely or is not.
6:40
Permanent, is in the way of the
6:45
truth, circa 475 BC.
6:49
To decide whether
6:49
existence emerging from
6:52
nothingness is even logically
6:52
possible, we need a precise
6:55
definition of nothing. For
6:55
instance, by nothing do we mean
6:59
no things? Or do we mean
6:59
absolute nothingness? No laws,
7:03
structures, properties or
7:03
principles? defining nothing.
7:09
Quote, it might have been true
7:09
that nothing ever existed. No
7:13
living beings, no stars, no
7:13
atoms, not even space or time.
7:19
When we think about this
7:19
possibility, it can seem
7:22
astonishing that anything
7:22
exists. And quote, Derek parfit,
7:28
in why anything? Why this 2008?
7:34
What is nothing? It seems like a
7:34
straightforward question. Just
7:39
keep removing things until there
7:39
is nothing left. Start with the
7:44
universe as it is. wipe away all
7:44
the matter and energy. take away
7:50
all the quantum fields of the
7:50
vacuum, and any virtual
7:53
particles popping in and out of
7:53
existence. And voila,
7:58
nothingness. nothingness is
7:58
reality after we delete
8:02
everything out of existence. But
8:02
wait, there's still space, it
8:08
still has dimensionality and
8:08
curvature. There is still time
8:13
and physical law, even if there
8:13
are no particles or fields left
8:17
to be governed by them. Let us
8:17
delete those two. Let's raise
8:22
the volume of space you raise
8:22
time and raise physical law.
8:27
Quote, when we say out of
8:27
nothingness, we do not mean out
8:31
of the vacuum of physics. The
8:31
vacuum of physics is loaded with
8:35
geometrical structure and vacuum
8:35
fluctuations and virtual pairs
8:40
of particles. The universe is
8:40
already in existence when we
8:44
have such a vacuum. Know when we
8:44
speak of nothingness we mean
8:49
nothingness, neither structure
8:49
nor law nor plan. And quote,
8:55
john Archibald Wheeler in law
8:55
without law 1983
9:01
What are we left with? If we
9:01
eliminate all the dimensions of
9:06
space and time we're left with
9:06
zero dimensional changes point
9:11
by point is still a thing. Can
9:11
we delete that two kinds of
9:17
nothing. So long as we operate
9:17
from a theory of geometry, we
9:21
can't define nothingness as
9:21
anything less than a space of
9:24
zero dimensionality. This leaves
9:24
us with a point. If we want to
9:30
eliminate the point, we need to
9:30
define nothingness not as a
9:33
space of zero dimensionality,
9:33
but as something non geometric.
9:38
For this, we must define
9:38
nothingness in terms of some
9:41
other theory. But any theory we
9:41
might choose has its own notion
9:46
of nothing. In other words,
9:46
nothingness is theory dependent.
9:51
For physics, it's no energy, the
9:51
vacuum for geometry, it's no
9:58
dimensionality, a point For set theory, it's no
10:00
elements, the empty set. For
10:05
arithmetic, it's no magnitude
10:05
zero. For information theory,
10:11
it's no information, zero bits.
10:11
There is an unlimited number of
10:16
possible theoretical systems.
10:16
Does this mean there are also
10:21
unlimited conceptions of
10:21
nothing, quote, nothing is
10:26
simple, not even nothing. And
10:26
quote, Bruno Mars shall,
10:34
might there be a true nothing
10:34
one with no laws, principles,
10:38
nor any theory behind it? Or
10:38
might every conception of
10:42
nothing require a theory of
10:42
things in order to declare that
10:45
there are none of them? rules
10:45
for nothing. We are called for
10:51
absolute nothingness, neither
10:51
structure nor law nor plan, but
10:56
is this kind of absolute nothing
10:56
achievable. For instance, the
11:01
law of identity holds that for
11:01
any A, A equals a, without such
11:07
a rule, there would be nothing
11:07
to ensure that nothing stayed
11:10
nothing, and didn't later become
11:10
equal to something. from
11:14
nothingness to persist, the
11:14
rules of logic must apply.
11:18
Further, if nothingness is the
11:18
state where zero things exist,
11:22
then the rules of arithmetic
11:22
must also hold to ensure that
11:26
zero equals zero rather than
11:26
zero equals one. For that, to
11:31
remain no things requires some
11:31
minimum set of laws, there might
11:36
be no things as such, but the
11:36
idea of no laws seems
11:40
incompatible with their being
11:40
and remaining no things. Quote,
11:45
in the beginning, there was only
11:45
truth, logic and their relation,
11:50
no possible reality can do
11:50
without them. CW varieties in
11:55
four dimensional reality
11:55
continued 2018.
12:00
If there were no logic, what
12:00
logic or reason ensures that
12:04
nothing comes from nothing. If
12:04
there were no laws, what law
12:08
principle would prohibit the
12:08
spontaneous emergence of a
12:12
universe? The trouble with
12:12
nothing? Can we define nothing
12:17
in a way that suppresses all
12:17
forms of existence? That is to
12:22
not only have no things but an
12:22
absolute nothingness and
12:25
nothingness of no objects,
12:25
neither abstract nor concrete,
12:29
no properties, no laws, no
12:29
principles, and no information
12:34
content? Or is this a fool's
12:34
errand? One that leads to a
12:40
logical inconsistency and thus
12:40
an impossibility? Might
12:44
nothingness be, in some sense
12:44
unstable? If absolute
12:49
nothingness can be shown to be
12:49
an impossible dream, it will
12:52
advance us on our path to
12:52
discover the reason for
12:55
existence. It might even reveal
12:55
some self existence or
12:59
necessarily existence thing,
12:59
properties of nothing. Anytime
13:04
we delete something from
13:04
reality, we leave something else
13:08
in its place. When we deleted
13:08
matter, we created a vacuum.
13:13
When we eliminated light, we
13:13
created darkness. When we
13:17
removed heat we created cold.
13:17
When we deleted space, we
13:22
created a point, quote, the idea
13:22
of nothingness has not one jot
13:28
more meaning than a square
13:28
circle, the absence of one thing
13:32
always being the presence of
13:32
another, which we prefer to
13:35
leave aside because it is not
13:35
the thing that interests us all
13:38
the thing we were expecting,
13:38
suppression is never anything
13:41
more than substitution, or two
13:41
sided operation which we agree
13:45
to look at from one side only.
13:45
So that the idea of the
13:48
absolution of everything is self
13:48
destructive, inconceivable. It
13:51
is a pseudo idea, a mirage
13:51
conjured by our own imagination,
13:57
on rebirths, and in the two
13:57
sources of morality and religion
14:00
1935. If every deletion is a
14:03
substitution for something else,
14:06
then appeal nothing devoid of
14:06
any properties whatever is
14:10
impossible. So while we might
14:10
succeed in removing all material
14:14
things from reality, we could
14:14
not remove all properties from
14:18
reality. The existence of
14:18
properties appears in escapable
14:23
nothingness of any kind will
14:23
always have some description and
14:27
properties, even when it's just
14:27
a cold, dark, empty vacuum. But
14:33
how far can we go in eliminating
14:33
properties. For instance, if we
14:38
define nothingness as the empty
14:38
set from set theory, what
14:42
properties would remain,
14:42
temperature has no meaning for a
14:46
set will any properties remain
14:46
for such a nothing? properties
14:51
of zero? Every conception and
14:51
the definition of nothing
14:55
contains at its heart zero for
14:55
any conception of
15:00
thing, nothing will always be
15:00
zero of them. The vacuum, zero
15:05
energy, geometry, zero
15:05
dimensionality, the empty set,
15:11
zero elements, arithmetic, zero
15:11
magnitude, information theory,
15:18
zero bits. If zero is a
15:18
universal property of nothing,
15:23
we must ask what are the
15:23
properties of zero? What does
15:27
zero bring to the table of
15:27
reality? Zero has many
15:31
properties. It's even, it's the
15:31
additive identity. It's the only
15:36
number that's neither positive
15:36
nor negative. It's the number of
15:40
elements in the empty set and
15:40
the number of even Prime's
15:43
greater than two. In fact, zero
15:43
has more properties than we
15:48
could list if we recruited all
15:48
the atoms in the observable
15:51
universe to serve as paper and
15:51
ink. This effort is doomed
15:55
because zeros properties are
15:55
infinite in number. zeros
16:00
factors couldn't be listed as
16:00
zero has infinitely many of
16:03
them. Every number evenly
16:03
divides zero and hence is one of
16:07
zeros factors. Aside from zeros
16:07
factors, we could list infinite
16:13
trivial properties of 00 is the
16:13
difference between one and one
16:17
and it's the difference between
16:17
two and two. And it's the
16:20
difference between three and
16:20
three and so on. But there are
16:24
also an infinite number of non
16:24
trivial properties of zero. Some
16:28
are even beyond the
16:28
understanding of today's
16:31
mathematicians. As an example,
16:31
mathematicians have for
16:35
centuries wondered, are there
16:35
even numbers greater than two
16:40
that aren't the sum of two
16:40
primes? This question is known
16:44
as goldbach conjecture after
16:44
Christian goldbach, who posed it
16:47
in 1742. Nearly three centuries
16:47
later, it remains unsolved.
16:54
Between 2002 1002 a $1 million
16:54
prize was offered to anyone who
17:00
could answer this question. All
17:00
this money to settle a question
17:04
about a property of zero. To
17:04
decide is zero the number of
17:09
exceptions to go box rule, we
17:09
now see why nothing is simple,
17:15
not even nothing. All
17:15
definitions of nothing include
17:19
the concept of zero. Far from
17:19
being simple. Zero is an object
17:24
of unlimited complexity. An
17:24
explosion of entities can zero
17:30
exist in isolation, completely
17:30
alone from other numbers, or do
17:34
relationships between numbers
17:34
make them inseparable. zeros
17:39
properties reference other
17:39
numbers. And each of these
17:43
numbers carries its own set of
17:43
properties and relations to the
17:46
other numbers are the properties
17:46
of one any less real than the
17:50
properties of zero, perhaps in a
17:50
reality having no things one is
17:56
meaningless. In a reality
17:56
containing nothing, there are no
18:00
things as such, at least no
18:00
material things. But in such a
18:05
nothing, there is an abstract
18:05
thing. 00 reflects the number of
18:10
material things to count. But
18:10
how many abstract things are
18:15
there to count, there is at
18:15
least one, the one number that
18:19
exists to define the number of
18:19
material things is zero. But if
18:24
we have one number, and it is
18:24
one thing to count, now another
18:28
number exists one, we then have
18:28
zero and one together as the
18:33
only numbers. But now we have
18:33
two numbers. Now to exists. This
18:40
is how numbers are defined in
18:40
set theory. Within set theory,
18:45
each number is formed as the set
18:45
of all previous sets. The
18:49
process starts with the empty
18:49
set, which contains zero things.
18:55
zero equals the empty set.
18:58
One equals the set of 02 equals
18:58
the set of zero and one,
19:07
three equals the set of 01 and
19:07
two,
19:12
four equals the set of 012 and
19:12
three, it seems once a single
19:19
abstract number is admitted,
19:19
each next number comes to life
19:23
as the count of the abstract
19:23
numbers that preceded it. Is
19:27
there any way to stop the
19:27
proliferation of infinite
19:29
abstract entities? If zero
19:29
exists by virtue of there being
19:34
zero things to count, then on
19:34
that basis, shouldn't every
19:38
number have the same rights to
19:38
exist by virtue of being the
19:41
number of proceeding numbers
19:41
there are to count, quote, the
19:46
existence of any number in
19:46
virtue of its properties entails
19:50
the existence of all the others
19:50
is a system of mathematics
19:53
couldn't exist bereft only of
19:53
the number, say 42 and the
19:58
existence of any number In virtue of the false set of
20:00
its properties or structural
20:03
relationships entails the
20:03
existence of every other number.
20:07
And quote, David Pearson. Why
20:07
does anything exist 1995
20:15
set theory and building up
20:15
numbers from the empty set of
20:18
modern ideas, they appeared
20:18
around the turn of the 20th
20:22
century. Yet the idea of numbers
20:22
giving rise to themselves goes
20:26
back much farther. Quote, the
20:26
Tao gives birth to one, one
20:33
gives birth to two, two gives
20:33
birth to three, three gives
20:38
birth to all things, large die
20:38
in chapter 42 of Tao Te Ching,
20:44
circa 600 BC, not true nothing. Whenever we
20:47
specify or define nothing, we
20:52
invoke theories and concepts,
20:52
which in turn, lead to
20:56
properties and abstract
20:56
entities. But what if we forego
21:00
even specifying nothing? might
21:00
this be a path to achieve
21:04
absolute nothingness? A true
21:04
nothing having
21:10
no things, no objects?
21:14
No definitions, no properties,
21:18
no abstract entities, no
21:18
concepts.
21:22
No sex, no numbers.
21:26
No set theory, no mathematics,
21:30
no specifications, no
21:30
information. avoiding all this
21:35
we have no theories of any kind.
21:35
We are left with a plain and
21:39
simple, pure, unadulterated
21:39
nothing at all. But again, this
21:44
leads to trouble. There's a
21:44
problem with this kind of
21:48
nothing and nothing of no
21:48
information is identical to
21:51
everything. Quote, we note that
21:51
the collection of all possible
21:56
descriptions has zero complexity
21:56
or information content. This is
22:01
a consequence of algorithmic
22:01
information theory, the
22:04
fundamental theory of computer
22:04
science. There is a mathematical
22:09
equivalence between the
22:09
everything as represented by
22:12
this collection of all possible
22:12
descriptions and nothing has
22:15
state have no information. And
22:15
quote, Russell Standish, in
22:21
theory have nothing 2006.
22:25
At first, this sounds counter
22:25
intuitive, if not outright
22:29
wrong. Yet this consequences
22:29
something we intuitively
22:32
understand in other contexts.
22:32
Let's review three such cases on
22:38
sculpted marble and unsent
22:38
email, and the library of
22:42
baybel. Each demonstrates an
22:42
equivalence between the nothing
22:46
of no specification and the
22:46
everything of all possibilities
22:50
and sculpted marble. Before
22:50
marked by a sculptors chisel, a
22:55
block of marble contains every
22:55
figure, or at least every figure
22:59
fitting the dimensions of the
22:59
block. Michelangelo's piatto was
23:03
in the block before he uncovered
23:03
it. It was there with all the
23:07
other figures. To bring forth
23:07
the piatto alone required the
23:12
addition of information,
23:12
Michelangelo had to uniquely
23:16
specify the pietta from among
23:16
the set of all possibilities.
23:20
Quote, there is a beautiful
23:20
angel in that block of marble
23:25
and I am going to find it all I
23:25
have to do is to knock off the
23:29
outside pieces of marble and be
23:29
very careful not to cut into the
23:33
angel with my chisel. In a month
23:33
or so you will see how beautiful
23:37
it is. George F Pentecost in the
23:37
angel in the marble 1883.
23:45
This specification requires
23:45
adding information to the block
23:49
by way of chisel marks. It is
23:49
only in the absence of this
23:53
information in the absence of
23:53
any chisel marks that all
23:57
possible figures remain. In this
23:57
sense information is subtractive
24:02
rather than additive. When
24:02
information specifies it
24:06
eliminates from the pre existing
24:06
infinite set of possibilities.
24:10
Absent such information, all
24:10
possibilities remain an unsent
24:16
email you are at your desk
24:16
awaiting an important email from
24:21
your boss. Before this message
24:21
arrives, you know nothing about
24:25
the contents of this email. You
24:25
are in a state of having no
24:29
information. But there is one
24:29
thing you know before the email
24:33
arrives. The email will be one
24:33
message from among the infinite
24:37
set of possible emails. Only
24:37
after the email arrives in your
24:42
inbox do you learn which from
24:42
among the infinite set of
24:45
messages the boss chose to send
24:45
you? But consider the case where
24:49
instead of sending a single
24:49
email, the boss sent you every
24:53
possible email Would you be able
24:53
to learn anything from these
24:57
infinite messages about what
24:57
your boss wants?
25:00
The lack of specification in the
25:00
infinite set of messages is
25:04
equal to the lack of
25:04
specification that existed prior
25:07
to receiving anything. Both
25:07
states are equivalently
25:10
unspecified. Therefore, both
25:10
represents states of complete
25:15
ignorance and a state of having
25:15
zero information. Having every
25:20
message is as informative as
25:20
having no message. The Library
25:25
of baybel one of the best
25:25
illustrations of the uselessness
25:29
of all information comes from
25:29
Jorge Luis Bohr has his concept
25:33
of a total library, described in
25:33
his short story The Library of
25:37
baybel. This library is
25:37
described as follows, quote, the
25:44
universe, which others call the
25:44
library is composed of an
25:47
indefinite and perhaps infinite
25:47
number of hexagonal galleries
25:51
with vast air shafts between
25:51
surrounded by very low railings.
25:56
from any of the hexagons, one
25:56
can see interminably the upper
26:00
and lower floors. There are five
26:00
shelves for each of the hexagons
26:05
walls. Each shelf contains 35
26:05
books of uniform format. Each
26:10
book is a 410 pages, each page
26:10
have 40 lines, each line have
26:16
some 80 letters which are black
26:16
in color. This thinker observed
26:20
that all the books, no matter
26:20
how diverse they might be, are
26:24
made up of the same elements,
26:24
the space, the period, the
26:28
comma, the 22 letters of the
26:28
alphabet. He also alleged to
26:32
factor which travelers have
26:32
confirmed in the vast library
26:35
there are no two identical
26:35
books. From these two
26:39
incontrovertible premises he
26:39
deduced that the library is
26:42
total and that it shelves
26:42
register all the possible
26:45
combinations of the 20 odd
26:45
orthographical symbols. Jorge
26:50
Luis Boer has in the library of
26:50
baybel 1941.
26:56
From the provided information,
26:56
we can calculate the number of
26:59
books in this library. This
26:59
total library contains every
27:04
possible 410 page book
27:04
representing every possible
27:08
arrangement of 25 characters.
27:08
Each page with 40 lines and 80
27:14
characters contains 3200
27:14
characters. Each book with 410
27:21
pages contains 410 times 3200 or
27:21
1,312,000 characters. With an
27:30
alphabet of 25 characters. This
27:30
gives 25 to the 1,312,000 power
27:36
possible books. This number is
27:36
25 multiplied by itself over a
27:42
million times. To put its
27:42
magnitude in context, the number
27:46
of atoms in the observable
27:46
universe is only 25 to the power
27:50
of 57, or 25. multiplied by
27:50
itself 57 times this library is
27:57
a great treasure. For in this
27:57
library we can find every book,
28:01
article, poem, and novel ever
28:01
written or that could be
28:05
written. We will find
28:05
descriptions of every scientific
28:09
theory from Newton's Principia
28:09
to Einstein's relativity to the
28:13
presently unknown theory of
28:13
quantum gravity, we will find
28:17
blueprints to world changing
28:17
technology is not yet invented
28:20
based on principles not yet
28:20
discovered. This library
28:25
possesses the greatest works of
28:25
literature, the complete works
28:28
of Shakespeare, Dickens and
28:28
Tolstoy. It also has every work
28:33
yet to be written, the completed
28:33
Game of Thrones series, as well
28:37
as the unfinished works of
28:37
talking Hemingway, and Twain.
28:42
The library has the untold
28:42
histories of every civilization,
28:46
including civilizations now last
28:46
time, it has the contents of
28:50
every scroll burned in the fire
28:50
of Alexandria. The library has
28:55
biographies of every person
28:55
who's ever lived, and even
28:58
biographies of those yet to be
28:58
born. What could be more
29:02
valuable than this boundless
29:02
trove of information with its
29:06
complete knowledge, its answers
29:06
to every mystery, and its
29:09
articulated solutions to every
29:09
problem. This is where the
29:13
equivalence between all
29:13
information and no information
29:16
rears its ugly head. it renders
29:16
the library worthless. There are
29:22
issues with this library to
29:22
start for every valid theory,
29:27
technology, history, and
29:27
autobiography in the library,
29:31
there are countless others that
29:31
are subtly wrong, inaccurate, or
29:34
utterly bogus. Worse, finding
29:34
any book with more than a few
29:39
grammatically sensible words is
29:39
next to impossible. Most books
29:44
are pure gibberish, or babble
29:44
indistinguishable from random
29:48
sequences of characters. A
29:48
typical page from a book in the
29:52
library of Babel contains
29:52
English sounding words, but
29:56
these are no more frequent than
29:56
random chance predicts.
30:00
Perhaps all hope is not lost.
30:00
Since this library contains
30:05
every possible book. Surely this
30:05
library contains books that
30:08
serve as indexes to find all the
30:08
other meaningful and sensible
30:12
books in the library. But this
30:12
dream is also impossible. Given
30:18
the number of books, it's
30:18
impossible to uniquely reference
30:21
any other book with a descriptor
30:21
shorter than the length of the
30:24
book. Thus, it takes all 410
30:24
pages to reference a specific
30:30
book in this library. Due to its
30:30
completeness, the library itself
30:35
is the most compact catalog of
30:35
all the books in the library. In
30:39
other words, a card catalog of
30:39
the library would be the library
30:43
itself. What if we organize the
30:43
books somehow, such as by
30:48
sorting them in alphabetical
30:48
order, then finding any
30:52
particular book would be easy.
30:52
This too suffers from a
30:56
pathological breakdown. While
30:56
this makes it easy to find any
31:01
particular book, The difficulty
31:01
shifts from finding the book to
31:04
deciding which book we want to
31:04
find. This is a consequence of
31:09
the library having every
31:09
possible book. As one seeks a
31:13
book of interest. One is faced
31:13
with 25 choices to choose which
31:17
of the 25 characters is next in
31:17
the content of the book we seek.
31:22
During the search, the seeker
31:22
must choose each next letter,
31:26
and must do this for all
31:26
1,350,000 characters in the
31:31
book. Thus, finding a book in
31:31
this library is as difficult as
31:36
writing the book in the first
31:36
place. In a way, we already have
31:40
access to this library, as we
31:40
are already free to put down any
31:44
sequence of characters we want,
31:44
and thus find a book that is
31:48
already present somewhere in
31:48
this total library. Thus, this
31:52
library provides no new
31:52
knowledge or information. Its
31:56
set of all books is as helpful
31:56
to us as if it had no books. And
32:01
so a total library offers
32:01
nothing. It's equivalent to
32:05
having no information at all.
32:05
You can explore this frustrating
32:10
enigma of the library of Babel,
32:10
Jonathan bazille, created an
32:15
online version of library of
32:15
Babel dot info. Everything from
32:19
nothing. information theory
32:19
reveals the equivalence between
32:24
the totality of all information
32:24
and the nothingness of zero
32:27
information. Both lack any
32:27
specification. Both are
32:32
completely uninformative, both
32:32
contained within them the
32:37
complete and infinite set of
32:37
every possibility. We've seen
32:41
this equivalence firsthand. We
32:41
saw it in the ns sculpted block
32:46
of marble, in the unsent email,
32:46
and in the library of baybel. So
32:51
is nothing of no specification,
32:51
or nothing or an everything.
32:56
less information more reality.
32:56
How much information is in the
33:01
library of baybel. To determine
33:01
this, we need only consider what
33:06
is the shortest description that
33:06
can generate the content of the
33:10
library. For instance, a library
33:10
containing one of each possible
33:15
410 page book with 3200
33:15
characters per page and a fixed
33:21
alphabet of 25 characters. The
33:21
proceeding description for the
33:26
library is 125 characters long,
33:26
there could be shorter
33:31
descriptions, but this sets an
33:31
upper bound for the information
33:34
content of the library of
33:34
baybel. It takes next to no
33:39
information to describe the vast
33:39
library of baybel.
33:42
Paradoxically, there's more
33:42
information in a single page
33:46
from a single book in the
33:46
library than in the entire
33:49
library itself. How could this
33:49
be? How can there be less
33:54
information in the library as a
33:54
whole than there is in a single
33:57
book or page from the library.
33:57
This is a consequence of
34:02
algorithmic information theory,
34:02
which includes the science of
34:05
data compression. It reveals
34:05
that it is simpler in terms of
34:10
needing a shorter description to
34:10
generate every book in the
34:13
library than it is to generate
34:13
only a single book or a single
34:17
page of a book in the library. A
34:17
shorter, less specific and more
34:22
general description casts a
34:22
wider net. A single book
34:26
requires 1,312,000 characters.
34:26
The Library of Babel requires
34:33
125 characters. all possible
34:33
books requires 18 characters.
34:41
The description or possible
34:41
books needs fewer characters
34:45
than the description of the
34:45
library of Babel, but it defines
34:48
a much larger set of books. In
34:48
fact, it defines an infinite set
34:52
of books of all possible lengths
34:52
and character sets. The Library
34:57
of baybel though vast was still
35:00
finite, Mike the same apply to
35:00
our universe and reality. To
35:05
describe one universe like ours
35:05
requires a vast amount of
35:09
information. It requires
35:09
specifying not only the physical
35:13
laws, but also the position,
35:13
direction and speed of every
35:17
particle in the universe. This
35:17
is estimated to require on the
35:21
order of 10 to the power of 90
35:21
bits. Yet to specify every
35:26
possible universe of our kind, a
35:26
multiverse of every possible
35:30
arrangement of particles ruled
35:30
by our laws of physics needs
35:34
much less information. Such a
35:34
multiverse requires only the
35:38
information to define the
35:38
physical laws, particle types,
35:42
fundamental forces and constants
35:42
of nature. This can be done in
35:47
just a few pages of equations.
35:47
describing our specific
35:51
universes like describing a
35:51
specific book from the library
35:55
of baybel. It needs more
35:55
information than the library
35:59
itself. In theories, such as the
35:59
string theory landscape, the
36:03
constants of nature are not
36:03
specified by the theory leading
36:07
to an even greater multiverse
36:07
consisting of every possible
36:10
universe having every set of
36:10
possible values for the
36:13
constants of nature, for
36:13
example, different values for
36:16
things like the electron mass
36:16
and the strength of
36:18
electromagnetism. There are
36:18
reasons to suspect this for
36:23
something like it is true. For
36:23
one, it explains why laws of
36:27
physics and constants of nature
36:27
appear fine tuned for the
36:31
emergence of life. See, was the
36:31
universe made for life. This
36:37
description of a string theory
36:37
landscape needs less
36:40
information, it might save a
36:40
page by not having to include
36:44
the 30 some odd constants of
36:44
nature, and yet, it describes a
36:48
vastly larger multiverse. the
36:48
observable universe with
36:53
particle velocities, physical
36:53
constants and physical equations
36:57
requires 10 to the 90 bits or
36:57
about 10 to the 85 pages to
37:01
specify the quantum multiverse
37:01
with physical constants and
37:05
physical equations requires
37:05
approximately 144,000 bits or
37:10
about six pages to specify. The
37:10
string theory landscape with its
37:15
physical equations requires
37:15
approximately 120,000 bits or
37:19
about five pages to specify all
37:19
physical possibility requires
37:25
zero bits. What happens when the
37:25
length of reality's description
37:30
goes to zero? This would leave
37:30
the equations themselves
37:34
unspecified, implying an even
37:34
greater multiverse. This
37:38
multiverse includes universes
37:38
not just of every arrangement of
37:42
matter, nor universes of every
37:42
set of constants, but universe
37:46
is ruled by every kind of
37:46
physical equations. Quote, if
37:51
all possible string vacuolar
37:51
spacetime geometries, masses of
37:55
elementary particles and
37:55
interaction strengths and laws
37:59
and by laws of physics are
37:59
realized, then all possible
38:02
descriptions are satisfied. This
38:02
is equivalent to zero
38:06
information. And quote, David
38:06
Pearson, why does anything
38:12
exist? 1995.
38:16
Thus, to specify all possible
38:16
physical laws, all possible
38:20
physical constants for all
38:20
possible universes, needs no
38:24
information at all. Might we
38:24
inhabit such a nothing. This is
38:30
the thesis of Russell Standish,
38:30
his 2006 book theory of nothing.
38:35
Standish believes our universe
38:35
with its seemingly vast quantity
38:39
of information is something like
38:39
a book in the library of baybel.
38:44
We will then be denizens of
38:44
nothing, occupying a place
38:47
within a total reality which
38:47
altogether amounts to zero
38:50
information. Such a reality one
38:50
of zero information is the
38:56
simplest state of existence.
38:56
It's simpler than an empty
38:59
vacuum or a geometrical point.
38:59
As these both need a nonzero
39:04
amount of information to
39:04
describe necessary existence.
39:09
We've attempted but
39:09
frustratingly failed to define a
39:13
true nothing. When we tried to
39:13
specify a nothing, whether as a
39:17
vacuum, a point or an empty set,
39:17
we inevitably invoke properties,
39:22
abstract entities, the numbers
39:22
zero and the infinitude of
39:25
numbers and their relationships.
39:25
Furthermore, this specification
39:31
is not an absolute nothing as it
39:31
requires reality to have a
39:34
nonzero amount of information to
39:34
specify it. Alternatively, if we
39:39
attempt to nothing of zero
39:39
information and zero
39:42
specification, we get a total
39:42
reality containing all
39:45
possibility. Neither approach
39:45
succeeds in bringing about
39:49
absolute nothingness. Moreover,
39:49
these approaches rely upon and
39:54
assume the validity of logical
39:54
principles and consistency. No
39:59
reality. Not even and nothing appears
40:00
possible without laws and
40:03
principles of logic. And so the
40:03
goal of the philosophers nothing
40:08
the neither structure nor law,
40:08
nor plan kind of true nothing at
40:12
all seems an impossible dream.
40:12
The nothings we attempt to break
40:17
down and lead to some things. With no structure, there are
40:20
zero structures. This introduces
40:24
zero, and with it the structure
40:24
of all numbers and their
40:27
interrelations. With no law, there are no
40:30
restrictions on what can or
40:33
cannot exist nor any law to
40:33
prevent things spontaneously
40:37
popping into existence. With no plan, there is no
40:40
information which is equivalent
40:44
to a totality. Inspired by his
40:44
discovery of binary numbers,
40:49
libraries wrote to the Duke of
40:49
Brunswick in 1679, suggesting a
40:53
design for a coin. He titled it
40:53
imago creation is all the image
40:58
of creation. Its motto reads,
40:58
quote, Omnibus x nihill, do send
41:06
these sufficeth, Unum for
41:06
producing everything out of
41:10
nothing, one principle is
41:10
enough. And quote, Gottfried
41:15
Wilhelm Leibniz in letter to
41:15
Duke 1679.
41:21
If a true and absolute Nothing
41:21
is impossible, or unstable, does
41:24
this mean there must be self
41:24
creating or self existent
41:27
things? kind of thing exist out
41:27
of logical necessity? Because
41:32
its absence is impossible? What
41:32
might the nature of such things
41:36
be a self existence thing? If
41:36
something did not emerge out of
41:42
nothing, then there's only one
41:42
other possibility that there is
41:46
something that has always
41:46
existed. In other words,
41:50
nothingness is not the default
41:50
state of reality. Quote, it is
41:55
extraordinary that there should
41:55
exist anything at all. Surely,
41:59
the most natural state of
41:59
affairs is simply nothing, no
42:03
universe, no God, nothing. But
42:03
there is something Richard
42:09
Swinburne in Is there a god
42:09
1996.
42:14
Given that something exists, it
42:14
either came from nothing or else
42:18
something has existed from the
42:18
beginning, the existence of this
42:22
thing is somehow necessary, it
42:22
existed without any proceeding
42:27
cause. This, we also find
42:27
contrary to intuition. It's
42:33
strange because everything we
42:33
are familiar with can trace its
42:36
existence to some earlier cause.
42:36
Manufactured things are made by
42:41
people, or by machines that were
42:41
made by people. Life comes from
42:46
other life. Things not created
42:46
by humans or other life, like
42:51
rivers and mountains are created
42:51
by natural forces acting on
42:54
matter. It seems to defy reason
42:54
for a thing to exist without a
42:59
cause. And yet, we know the
42:59
universe exists. The universe
43:05
either came from some proceeding
43:05
cause or else the universe has
43:09
always existed is self existent
43:09
or self creating, there is no
43:14
third option. If the universe is
43:14
not the end of this causal
43:18
chain, then something else is
43:18
therefore we must accept some
43:23
things are self creating come
43:23
out of nothing, or are self
43:27
existent. Let's call such a
43:27
thing causeless. Existing
43:32
without cause, take anything
43:32
that exists the chair, you're
43:37
sitting in your conscious
43:37
thoughts, the Eiffel Tower. For
43:41
the purposes of the reasoning,
43:41
it doesn't matter what thing we
43:44
start with. Given that this
43:44
thing exists, there are two
43:49
possibilities either that thing
43:49
was caused or it was not caused.
43:54
If a thing has no cause, then it
43:54
is causeless. Otherwise, the
43:59
thing has a cause and its
43:59
existence is owed to some other
44:02
thing. If we follow the chain of
44:02
causality back towards an
44:06
ultimate root cause there are
44:06
three possibilities. One, first
44:12
cause the chain of causality
44:12
comes to an end in a first
44:16
cause. to infinite regression,
44:16
the chain of causality continues
44:22
forever. Three, causal loop, the
44:22
chain of causality forms a
44:28
closed cycle, or a loop. These
44:28
represent all possibilities. The
44:34
trace either ends or first cause
44:34
or it continues forever. If it
44:39
continues forever, it forms an
44:39
infinite chain that's either
44:42
open an infinite regression, or
44:42
closed a causal loop. In all
44:48
three cases, we find something
44:48
that has always existed, either
44:52
the first cause the infinite
44:52
chain itself, or the causal loop
44:56
itself, this thing which has
44:56
always exists
45:00
Did we can describe as causeless
45:00
first Cause if when tracing back
45:06
through the series of causes, we
45:06
happen upon something causeless
45:10
then our existence results from
45:10
a first cause. Leading
45:14
cosmological theories such as
45:14
the Big Bang and cosmic
45:18
inflation posits that the
45:18
universe is not infinitely old,
45:21
but rather underwent an abrupt
45:21
event where it came into
45:24
existence that our universe has
45:24
appoints that maybe marketers
45:28
are beginning leaves open the
45:28
possibility that there is a
45:31
proceeding cause for our
45:31
universe. Another possibility is
45:35
that the universe has its own
45:35
cause emerging as a random
45:39
quantum fluctuation allowed by
45:39
laws of physics. many religions
45:44
speak of the first cause as a
45:44
divine act of creation. In such
45:48
a case, God would be the first
45:48
cause. Yet some other non
45:53
theistic objects could as well
45:53
be responsible for our
45:56
existence. If the universe is
45:56
not eternal, we should look for
46:00
some reason for the sudden
46:00
appearance of the universe to
46:03
explain how it could arise by
46:03
itself be self existent, or be
46:08
the product of some prior cause.
46:08
Infinite regression. If our
46:13
universe has an eternal history,
46:13
or if it belongs to a reality
46:17
having an eternal history, then
46:17
we exist due to an infinite
46:21
regression. A number of
46:21
scientific theories propose that
46:25
our universe is eternal. Prior
46:25
to wide acceptance of the Big
46:30
Bang, the steady state model was
46:30
popular. It proposed that the
46:34
universe is eternally expanding
46:34
with new matter perpetually
46:38
created to fill the void in the
46:38
newly made space. Since the
46:42
acceptance of the Big Bang,
46:42
various new models suppose that
46:46
the Big Bang is itself part of
46:46
an eternal succession of big
46:50
bangs. Roger Penrose is
46:50
conformal. cyclic cosmology
46:54
supposes that the heat death of
46:54
our universe could appear as a
46:58
new big bang in the next year
46:58
and Lee Smolin proposed
47:02
cosmological natural selection
47:02
where in a new universe spawns
47:06
every time a black hole forms.
47:06
Accordingly, if the laws mutate,
47:11
he suggests that universes might
47:11
even evolve towards having laws
47:15
that maximize the production of
47:15
black holes. Sean Carroll notes
47:20
that the equations of quantum
47:20
mechanics unlike those of
47:23
general relativity, permit
47:23
physicists to calculate
47:26
eternally into the past or
47:26
future. With a theory of quantum
47:30
gravity, we could in principle
47:30
predict backwards to times
47:33
proceeding the Big Bang, quote,
47:33
the Schrodinger equation has an
47:39
immediate, profound consequence.
47:39
Almost all quantum states evolve
47:44
eternally toward both the past
47:44
and the future. Unlike classical
47:49
models, such as spacetime in
47:49
general relativity, which can
47:53
hit singularities beyond which
47:53
evolution cannot be extended,
47:56
quantum evolution is very
47:56
simple. If this setup describes
48:01
the real world, there is no
48:01
beginning nor end to time. Shown
48:06
Carolyn, why is there something
48:06
rather than nothing? 2018.
48:13
According to ancient legends,
48:13
the world rests on the back of a
48:17
cosmic turtle. When asked what
48:17
the cosmic turtle rests on a
48:21
common responses, it is turtles
48:21
all the way down an infinite
48:25
regression. If an infinite
48:25
regression is true, there is no
48:30
ultimate cause. However, we
48:30
might still look for an ultimate
48:34
explanation for the chain of
48:34
causes. causal.
48:39
It might be that our existence
48:39
is part of an infinite series,
48:43
but one that repeats forever. If
48:43
true, we are stuck in a never
48:48
ending causal loop. The
48:48
hypothesized big bounce is an
48:52
example of a cyclic cosmology.
48:52
In 1922, Alexander Freedman
48:58
applied Einstein's equations of
48:58
general relativity to the
49:01
universe as a whole. He found
49:01
that for certain values of the
49:05
density of the universe and the
49:05
cosmological constant, the
49:09
universe will expand for a
49:09
period of time, slow down, and
49:13
eventually re collapse. In his
49:13
1923 book, the world of space
49:18
and time, Friedman speculates
49:18
that the collapse or Big Crunch
49:23
could rebound in a big bounce,
49:23
causing a new Big Bang. The
49:27
process could repeat forever.
49:27
The idea of cyclic cosmology has
49:32
appealed to many scientists,
49:32
including Georges Lemaitre,
49:36
Richard Tolman, George gameau,
49:36
William Bonnell, Herman Sangster
49:41
and Robert Dick, among others.
49:41
Quote, we can now ask ourselves
49:47
two important questions. Why was
49:47
our universe in such a highly
49:52
compressed state? And why did it
49:52
start expanding? The simplest
49:58
and mathematically most a consistent way of answering
50:00
these questions would be to say
50:03
that the big squeeze which took
50:03
place in the early history of
50:06
our universe was the result of a
50:06
collapse which took place at a
50:09
still earlier era. And that the
50:09
present expansion is simply an
50:14
elastic rebound which started as
50:14
soon as the maximum permissible
50:17
squeezing density was reached.
50:17
And quote, George gameau in the
50:23
creation of the universe, 1952
50:28
cyclical cosmologies can be
50:28
found in many religions. For
50:32
example, there is the concept of
50:32
the Wheel of Time in the dharmic
50:36
religions. Quote, the most
50:36
elegant and sublime of these is
50:42
a representation of the creation
50:42
of the universe at the beginning
50:45
of each cosmic cycle, a motif
50:45
known as the cosmic dance of
50:48
Shiva. The God called in this
50:48
manifestation netta Raja, the
50:54
dance King has four hands. In
50:54
the upper right hand is a drum
50:58
whose sound is the sound of
50:58
creation. In the upper left hand
51:03
is a tongue of flame, a reminder
51:03
that the universe now newly
51:07
created will billions of years
51:07
from now be utterly destroyed,
51:12
and quote, Carl Sagan in Cosmos
51:12
1980.
51:18
But cyclic models lacking
51:18
observational evidence and
51:22
theoretical support remained on
51:22
the periphery of cosmology. In
51:27
1998, observations revealed the
51:27
expansion of the universe was
51:31
not slowing but accelerating.
51:31
This seems to rule out a future
51:36
collapse. The driver of this
51:36
acceleration, dark energy
51:41
remains little understood. If it
51:41
is constant, the expansion will
51:45
continue forever, but in some
51:45
theories, it varies with time
51:50
and so a later collapse may be
51:50
possible. cyclic models have
51:55
seen a revival. In 2001, Justin
51:55
Horry vert offered Paul Steiner
52:02
the Neil terrick proposed the
52:02
EAC pi erotic universe. This
52:06
idea marries string theory and
52:06
cosmology to give a model where
52:10
periodic brain collisions
52:10
trigger cycles of big bangs and
52:13
big crunches. If our universe is
52:13
part of a causal loop, no
52:18
beginning or end is
52:18
identifiable. But what got it
52:22
started? Did one of the
52:22
succession of states spring
52:26
forth out of nothing? Or might
52:26
the loop have always existed?
52:30
The nature of uncaused things
52:30
given that reality exists, we
52:36
know there must be an entity
52:36
that is causeless. What is it
52:40
about causeless entities that
52:40
makes them existent? If a first
52:45
cause, how did it bring itself
52:45
into existence? If an infinite
52:50
regression or causal loop? How
52:50
did it come into being? Might it
52:54
exist out of logical necessity?
52:54
Or is it a result of chance?
53:00
Almighty it exists simply
53:00
because it can exist, and
53:03
nothing forbids it. tracing
53:03
causes backwards can tell us
53:08
where the previous state came
53:08
from, but it won't answer where
53:11
the chain or loop itself came
53:11
from. Quote, some believe that
53:17
if all events were caused by
53:17
earlier events, everything would
53:20
be explained. That however, is
53:20
not so even an infinite series
53:27
of events cannot explain itself.
53:27
We could ask why this series
53:31
occurred rather than some other
53:31
series or no series? Derek
53:36
parfit in why anything? Why this
53:36
2008
53:43
what we are looking for is not a
53:43
cause, but a reason and
53:47
explanation. For in the cases of
53:47
the loops or infinite
53:51
regression, we can always find
53:51
an earlier cause, but may never
53:55
reach a satisfactory reason.
53:55
Quote, for the question to be
54:00
properly fully answered, we need
54:00
a sufficient reason that has no
54:04
need of any further reason. Or
54:04
because that doesn't throw up a
54:07
further why and this must lie
54:07
outside the series of contingent
54:11
things and must be found in a
54:11
substance which is the cause of
54:14
the entire series. It must be
54:14
something that exists
54:18
necessarily carrying the reason
54:18
for its existence within itself.
54:22
Only that can give us a
54:22
sufficient reason at which we
54:25
can stop having no further why.
54:25
Question taking us from this
54:29
being to something else. And
54:29
quote Gottfried Wilhelm Leibniz
54:35
in the principles of nature and
54:35
grace based on reason 1714.
54:41
If we seek a final because that
54:41
puts an end to any further wise,
54:45
we must find something that we
54:45
can show must exist. Not only
54:49
must this thing exist, but we
54:49
must also show how this thing
54:53
can account for the reality we
54:53
experience. Only then will we
54:57
have succeeded in our quest can
55:00
It's for self existence.
55:00
Throughout history,
55:04
philosophers, scientists and
55:04
religions have suggested
55:07
candidates for self existence.
55:07
These causeless entities
55:12
generally fall into one of seven
55:12
categories. One, logic to truth,
55:21
three, numbers, four,
55:21
possibility, five, the universe,
55:31
six, the higher plane, and seven
55:31
consciousness. Let's review each
55:39
candidate and its merits for
55:39
self existence. Afterwards, we
55:44
will consider whether that
55:44
entity could further serve as an
55:47
ultimate explanation or self
55:47
existence starting point from
55:50
which the rest of reality
55:50
emerges as a direct consequence
55:54
of that thing. Logic. Some
55:54
suppose rational principles,
55:59
like the laws of logic, are self
55:59
existent. Unlike physical laws,
56:05
logical laws have an air of
56:05
inevitability to them. These are
56:09
laws such as the law of identity, things are
56:12
identical to themselves. For
56:17
example, a equals A
56:20
the law of the excluded middle
56:20
statements are either true or
56:24
not true. The law of non contradiction, no
56:26
statement is both true and
56:30
false. These are laws that seem
56:30
inevitable and necessary in any
56:35
reality, as it's hard to imagine
56:35
any reality where logical laws
56:39
would not hold. If logical laws
56:39
apply in all universes and all
56:44
possible realities, they
56:44
represent universal laws,
56:48
applying everywhere and to
56:48
everything. If we can say laws
56:52
of physics exist, because all
56:52
matter a university is to
56:55
physical laws, then could we say
56:55
laws of logic exist? Because all
57:00
things in all possible realities
57:00
adhere to these logical laws? If
57:05
so, then laws of logic are self
57:05
existent. They are necessary
57:10
even in a reality of no things
57:10
as logical laws ensure nothing
57:14
equals nothing. Quote, if I
57:14
asked myself why bodies or minds
57:19
exist, rather than nothing, I
57:19
find no answer. But that a
57:23
logical principle, such as a
57:23
equals A should have the power
57:27
of creating itself triumphing
57:27
over the Lord throughout
57:30
eternity seems to be natural,
57:30
and quote, on rebirths and in
57:36
creative evolution 1907
57:40
this idea that logical law and
57:40
rational principles have
57:44
eternally existed predates
57:44
modern philosophers. It's a
57:47
cornerstone belief in Taoism.
57:47
Quote, there was something
57:53
formless and perfect before the
57:53
universe was born. It is serene,
57:59
empty, solitary, unchanging,
57:59
infinite, eternally present. It
58:07
is the mother of the universe,
58:07
for lack of a better name, I
58:12
call it the Tao Lao Jain,
58:12
Chapter 25, of Tao teaching,
58:17
circa 600 BC. Towel translates as the way
58:20
principles and natural order. A
58:26
similar sentiment is expressed
58:26
in Christianity. The Gospel of
58:30
john begins, quote, In the
58:30
beginning was the Word and the
58:36
Word was with God, and the Word
58:36
was God. gospel of john chapter
58:41
one verse, one 100 ad,
58:46
the term word is a translation
58:46
of verbal in Latin, which is a
58:50
translation of logos in Greek.
58:50
Logos has a deep and rich
58:54
meaning. Aside from word logos
58:54
also means reason, principles,
59:00
and rational law. Logos is the
59:00
root from which we get the word
59:05
logic. It is also the origin of
59:05
the suffix ology, as in biology,
59:10
geology and psychology, where it
59:10
means the principles explanation
59:16
and story they're off. quote,
59:16
If, however, he be admitted to
59:21
exist apart from matter in
59:21
virtue of his character as a
59:24
principle and a rational law,
59:24
logos, God will be bottleless
59:29
the creative power bottleless
59:29
plotinus in the NT ad,
59:35
six to 70 ad.
59:38
In Chinese Bibles, logos has
59:38
been translated as Tao. In this
59:44
way, both Taoist and Christian
59:44
ideas. Suppose that the Tao
59:47
slash logos, order reason,
59:47
principles, logic, rational law
59:52
exists prior to the material
59:52
universe. Truth Some believe
59:58
that truth is caused Plus, there seems to be some
1:00:00
essential difference between
1:00:03
zero is even and zero is odd.
1:00:03
Only one of them is true. Did
1:00:08
anything make it so? When did
1:00:08
this statement become true? Did
1:00:14
it require a human mind to
1:00:14
conceive of it as being true? Or
1:00:17
has it always been true? Mike
1:00:17
this property of truth have an
1:00:21
independent and necessary
1:00:21
existence. If logical laws apply
1:00:27
universally, then any well
1:00:27
formed statement is either true
1:00:30
or false. The law of non
1:00:30
contradiction says a statement
1:00:34
can't be both true and false.
1:00:34
The law of excluded middle says
1:00:39
a statement must be either true
1:00:39
or false, there is no middle
1:00:42
ground. Thus, if logical laws
1:00:42
apply to everything, they apply
1:00:47
to all statements, forcing on
1:00:47
them the objective property of
1:00:51
being either true or false. As
1:00:51
Derek parfit said, some truth is
1:00:56
logically necessary when it's
1:00:56
denial leads to a contradiction.
1:01:01
Accordingly, the truth that zero
1:01:01
is even would exist before
1:01:05
humans proved it. It would be
1:01:05
true before it was first spoken.
1:01:10
Presumably, it would be true
1:01:10
appcenter universal things, for
1:01:14
even in the case zero things
1:01:14
exist, it remains true that an
1:01:17
even number of things exist.
1:01:17
Quote, when we imagine how
1:01:22
things would have been if
1:01:22
nothing had ever existed, what
1:01:25
we should imagine away are such
1:01:25
things as living beings, stars
1:01:29
and atoms, there would still
1:01:29
have been various truths, such
1:01:34
as the truth that there were no
1:01:34
stars or atoms, or that nine is
1:01:38
divisible by three, we can ask
1:01:38
why these things would have been
1:01:42
true. And such questions may
1:01:42
have answers. Thus, we can
1:01:47
explain why, even if nothing had
1:01:47
ever existed, nine would still
1:01:52
have been divisible by three,
1:01:52
there is no conceivable
1:01:55
alternative. End quote, Derek
1:01:55
parfit, in why anything? Why
1:02:02
this 2008.
1:02:07
Ultimately, nothing is
1:02:07
responsible for creating this
1:02:10
truth. Truth exists out of its
1:02:10
own necessity. It has always
1:02:16
existed and could never not
1:02:16
exist. The idea of the primacy
1:02:21
of truth is very old. It can be
1:02:21
found in many religions, some of
1:02:25
which draw an equivalence
1:02:25
between God and truth. In the
1:02:30
3000 year old religion of
1:02:30
Zoroastrianism, it is said that
1:02:34
assha, meaning truth and order
1:02:34
is the Divine Law behind all
1:02:38
things. Quote, Iran, as India
1:02:38
presents us with a term which
1:02:44
has had to signify, first of
1:02:44
all, true statement, that this
1:02:47
statement, because it was true,
1:02:47
had to correspond to an
1:02:51
objective material reality. And
1:02:51
that, as the discourse did, this
1:02:56
reality must embrace all things.
1:02:56
And finally, that one recognized
1:03:00
in it a great cosmic principle
1:03:00
since all things happen
1:03:03
according to it, and quote, jack
1:03:03
dushane, demon, inherit cleitus
1:03:09
and Iran 1963.
1:03:12
In the book of Psalms, Chapter
1:03:12
31, verse five, God is called
1:03:17
the God of truth. In the Quran,
1:03:17
Allah hoc, meaning the truth is
1:03:22
one of the 99 names of God.
1:03:22
similar ideas are found in
1:03:27
dharmic religions. The moolman
1:03:27
ta, or route mantra is the most
1:03:32
important verse of the Sikh
1:03:32
religion. It begins there is one
1:03:37
creator whose name is truth and
1:03:37
is described as timeless beyond
1:03:41
birth or death, and self
1:03:41
existent in the Brahma Samhita,
1:03:46
a Hindu prayer book, the
1:03:46
primeval Lord give India is
1:03:49
described as the indivisible,
1:03:49
infinite, limitless truth.
1:03:54
Quote, if it is possible for the
1:03:54
human tongue to give the fullest
1:03:58
description of God by have come
1:03:58
to the conclusion that God is
1:04:02
truth. End quote. Mahatma Gandhi
1:04:02
in all men are brothers 1953
1:04:10
numbers. Some speculate that
1:04:10
numbers or their relationships
1:04:16
are self existent. If truth has
1:04:16
an independent existence, this
1:04:21
truth includes the infinite
1:04:21
truths describing all true
1:04:24
relationships between the
1:04:24
numbers. These include
1:04:28
arithmetical statements such as
1:04:28
two is even. Seven is prime. One
1:04:36
is greater than 02 plus two
1:04:36
equals four, and times zero
1:04:43
equals zero. And that the square
1:04:43
root of nine is three truths
1:04:49
concerning the numbers are
1:04:49
boundless. Might this infinite
1:04:54
truth provide a scaffolding and
1:04:54
structure to all the numbers and
1:04:58
if there is nothing more to numbers than their properties
1:05:00
and relations, then Mike numbers
1:05:03
in some sense really exist. It's
1:05:03
been said, math is the science
1:05:09
we could still do if we woke up
1:05:09
tomorrow and there was no
1:05:12
universe. The idea that math
1:05:12
holds some claim to reality is
1:05:16
known as mathematical realism,
1:05:16
or platonism. It's believed by
1:05:21
many, if not most
1:05:21
mathematicians. Quote, it is an
1:05:27
idea that many mathematicians
1:05:27
are comfortable with. In this
1:05:31
scheme, the truths that
1:05:31
mathematicians seek are in a
1:05:34
clear sense already there. And
1:05:34
mathematical research can be
1:05:38
compared with archaeology. The
1:05:38
mathematicians job is to seek
1:05:43
out these truths as a task of
1:05:43
discovery rather than one of
1:05:46
invention. Roger Penrose in the
1:05:46
big questions, what is reality?
1:05:52
2006.
1:05:56
But can number relations have
1:05:56
any reality in the absence of
1:05:59
things? If zero things exist, it
1:05:59
would have to be true that zero
1:06:04
not equal one, and also that
1:06:04
zero not equal to and true that
1:06:09
zero not equal any other number.
1:06:09
So even with no things, an
1:06:14
infinite number of arithmetical
1:06:14
relations are needed to avoid
1:06:17
contradiction and preserve
1:06:17
nothing of zero things. Quote,
1:06:23
if all things were absent, would
1:06:23
too and to make fobian non
1:06:27
reality remaining like that
1:06:27
until at least four things that
1:06:30
come to exist? Presumably, the
1:06:30
answer must be no. JOHN a Leslie
1:06:36
and Robert Lawrence Kuhn in the
1:06:36
mystery of existence 2013.
1:06:42
This idea that numbers have an
1:06:42
independent existence is
1:06:45
ancient. It can be traced to
1:06:45
some of the earliest records of
1:06:50
human thought. It was taught by
1:06:50
ancient philosophers, and is
1:06:54
found in the oldest religious
1:06:54
texts. Taoism, for instance,
1:07:00
sets the existence of numbers as
1:07:00
prior to things. Quote, the Tao
1:07:06
gives birth to one, one gives
1:07:06
birth to two, two gives birth to
1:07:11
three, three gives birth to all
1:07:11
things, larger and chapter 42 of
1:07:18
Tao Te Ching, circa 600 BC,
1:07:23
the Greek mathematician
1:07:23
Pythagoras taught all things are
1:07:26
number. Quote, Pythagoras
1:07:26
applied themselves to
1:07:31
mathematics, and were the first
1:07:31
to develop this science. And
1:07:35
through studying it, they came
1:07:35
to believe that its principles
1:07:38
are the principles of
1:07:38
everything. Aristotle in
1:07:41
metaphysics circa 350 BC.
1:07:46
Pythagoras was the first to
1:07:46
propose that the motions of the
1:07:49
planets are governed by
1:07:49
mathematical equations, which he
1:07:52
called the harmony of the
1:07:52
spheres. When Newton discovered
1:07:56
his law of universal
1:07:56
gravitation, some 2000 years
1:07:59
later, he credited Pythagoras
1:07:59
for the discovery. Across times,
1:08:04
mathematicians have described a
1:08:04
seemingly divine connection
1:08:08
between mathematics and reality,
1:08:08
quote, geometry, which before
1:08:14
the origin of things was co
1:08:14
eternal, with the divine mind
1:08:17
and is God himself for what
1:08:17
could they be in God which would
1:08:20
not be God Himself supplied God
1:08:20
with patterns for the creation
1:08:23
of the world and passed over to
1:08:23
man along with the image of God
1:08:27
yohannes Kepler in the harmony
1:08:27
of the world 1619
1:08:33
quotes from these considerations
1:08:33
it is now wonderfully evident
1:08:38
how a certain divine mathematics
1:08:38
or metaphysical mechanics is
1:08:41
employed in the very origination
1:08:41
of things. Gottfried Wilhelm
1:08:46
Leibniz in on the ultimate
1:08:46
origination of things 1697.
1:08:51
Quote, to all of us who hold the
1:08:51
Christian belief that God is
1:08:56
truth, anything that is true is
1:08:56
a fact about God. And
1:08:59
mathematics is a branch of
1:08:59
theology. An old Greek, a French
1:09:04
child, and a self taught Indian
1:09:04
each finds for himself the same
1:09:09
theory of geometrical conics.
1:09:09
The simplest and therefore, the
1:09:13
most scientific way of
1:09:13
describing this is that they
1:09:16
have discovered not created a
1:09:16
geometry that exists by itself
1:09:20
eternally the same for all the
1:09:20
same for teacher as for taught
1:09:24
the same for manners for God.
1:09:24
The truth that is the same for
1:09:29
manners for God is pure
1:09:29
mathematics. Hilda P. Hudson in
1:09:33
mathematics and eternity 1925
1:09:38
possibility. Some speculate that
1:09:38
simply not being impossible is
1:09:43
sufficient for being actual. If
1:09:43
true, then every possible object
1:09:49
structure and entity exists.
1:09:49
What then is impossible. At a
1:09:55
minimum, we can say self
1:09:55
contradictory things. For
1:09:59
example, pole square circles, married
1:10:00
bachelors, triangles with five
1:10:04
sides and so on. We might also
1:10:04
include things proven to not
1:10:09
exist. odd numbers easily
1:10:09
divisible by two, a largest
1:10:13
prime number, a sixth platonic
1:10:13
side. If consistency and
1:10:17
provability are the requirements
1:10:17
for possibility, then possible
1:10:21
existence is mathematical
1:10:21
existence. As David Hilbert
1:10:25
said, mathematical existence is
1:10:25
merely freedom from
1:10:29
contradiction. The idea that all
1:10:29
possible things exist has
1:10:33
enjoyed many names. In 1936,
1:10:33
Arthur Lovejoy dubbed it the
1:10:39
principle of plenitude. In 1981
1:10:39
Robert nozick named it the
1:10:44
principle of fecundity, David
1:10:44
Lewis, in 1986, developed it as
1:10:50
a theory he called modal realism
1:10:50
in Max Tegmark 1998 model of
1:10:55
multiverses he called it the
1:10:55
mathematical universe
1:10:59
hypothesis. Most recently, in
1:10:59
2008, Derek parfit, coined the
1:11:05
all worlds hypothesis, if all
1:11:05
possible objects are actual,
1:11:10
then our universe is just one
1:11:10
such possible structure and an
1:11:13
infinite and total set of all
1:11:13
possible structures. Anything
1:11:18
that could happen happens
1:11:18
somewhere, quote, there are so
1:11:23
many other worlds, in fact that
1:11:23
absolutely every way that a
1:11:27
world could possibly be is a way
1:11:27
that some world is. And as with
1:11:32
worlds, so it is with parts of
1:11:32
worlds, there are ever so many
1:11:37
ways that a part of a world
1:11:37
could be and so many and so
1:11:41
varied are the other worlds that
1:11:41
absolutely every way that a part
1:11:45
of a world could possibly be as
1:11:45
a way that some part of some
1:11:48
world is, end quote, David Lewis
1:11:48
in on the plurality of worlds
1:11:54
1986. Quote, if the universe is
1:11:57
inherently mathematical, then
1:12:02
why was only one of the many
1:12:02
mathematical structures singled
1:12:05
out to describe the universe, a
1:12:05
fundamental asymmetry appears to
1:12:10
be built into the heart of
1:12:10
reality. As a way out of this
1:12:14
conundrum, I have suggested that
1:12:14
complete mathematical symmetry
1:12:18
holds that all mathematical
1:12:18
structures exist physically as
1:12:22
well. Every mathematical
1:12:22
structure corresponds to a
1:12:25
parallel universe. And quote,
1:12:25
Max Tegmark in parallel
1:12:31
universes 2003
1:12:35
the idea that possibility is
1:12:35
sufficient for actuality is not
1:12:39
new. Arthur Lovejoy, who wrote
1:12:39
about the history of this idea,
1:12:44
traced it to 360 bc beginning
1:12:44
with Plato's theory of forms,
1:12:49
Plato hypothesized the realm
1:12:49
containing all possible forms
1:12:53
eternal, perfect idealizations.
1:12:53
We find this idea expressed in a
1:12:59
variety of ways throughout
1:12:59
history, quote, the one is all
1:13:05
things and not a single one of
1:13:05
them. It is because there is
1:13:09
nothing in it that all things
1:13:09
come from it in order that being
1:13:12
may exist, the one who is not
1:13:12
being but the generator of being
1:13:17
plotinus in the ads five, to one
1:13:17
to 70 ad,
1:13:23
quote, but to explain more
1:13:23
distinctly how from eternal or
1:13:28
essential metaphysical truths
1:13:28
there arise temporal contingent
1:13:31
or physical truths, we must
1:13:31
first observe that, from the
1:13:36
very fact that there exists
1:13:36
something rather than nothing,
1:13:39
it follows that impossible
1:13:39
things or in possibility or
1:13:43
essence itself. There is a
1:13:43
certain need of existence, or so
1:13:48
to speak, a claim to exist in a
1:13:48
word that essence of itself
1:13:52
tends to existence. Gottfried
1:13:52
Wilhelm Leibniz in on the
1:13:56
ultimate origination of things
1:13:56
1697.
1:14:01
Others have linked God's
1:14:01
infinite nature to an infinite
1:14:04
creation. Quote, from God's
1:14:04
supreme power, or infinite
1:14:10
nature, an infinite number of
1:14:10
things, that is, all things have
1:14:14
necessarily flowed forth in an
1:14:14
infinite number of ways, or
1:14:18
always flow from the same
1:14:18
necessity. In the same way as
1:14:22
from the nature of a triangle,
1:14:22
it follows from eternity and for
1:14:26
eternity, that it's three
1:14:26
interior angles are equal to two
1:14:29
right angles, Baruch Spinoza, in
1:14:29
ethics, 1677.
1:14:36
Quotes now thou have a truth
1:14:36
that the worlds of God are
1:14:40
countless in their number, and
1:14:40
infinite in their range. None
1:14:44
can reckon or comprehend them
1:14:44
except God, the all knowing the
1:14:48
all wise baja Allah in tablet to
1:14:48
offer circa 1885
1:14:56
quotes. It makes sense that an
1:14:56
infinitely creative
1:15:00
deity will create other
1:15:00
universes, not just our own. For
1:15:05
the theist, the existence of
1:15:05
multiple universes would simply
1:15:09
support the view that creation
1:15:09
reflects the infinite creativity
1:15:12
of the Creator. Robin a Collins
1:15:12
in spiritual information 2005
1:15:20
the universe. Some say that the
1:15:20
universe or the physical law
1:15:25
that enabled it to come into
1:15:25
existence has always existed and
1:15:29
so is self existent. The
1:15:29
reasoning is simple. If we know
1:15:34
at least one thing is causeless.
1:15:34
Why not just presume this
1:15:38
causeless thing is the universe
1:15:38
itself. Quote, I should say that
1:15:43
the universe is just there. And
1:15:43
that's all and quote Bertrand
1:15:49
Russell in Russell copplestone
1:15:49
debate 1948.
1:15:54
Perhaps there is no reason it
1:15:54
simply is and has no
1:15:59
explanation. Given the universe
1:15:59
exists, we know the universe is
1:16:04
possible. Perhaps it exists
1:16:04
because it is possible, and
1:16:09
nothing forbade it from
1:16:09
existing. But there are other
1:16:12
tracks to follow. Perhaps we can
1:16:12
demonstrate that the universe is
1:16:17
self creating, or that it exists
1:16:17
due to some higher law. Modern
1:16:23
cosmology made progress along
1:16:23
these directions. The theory of
1:16:28
cosmic inflation uses general
1:16:28
relativity to explain how a tiny
1:16:32
quantum fluctuation can inflate
1:16:32
into the huge universe we now
1:16:36
see, quote, inflation is
1:16:36
radically at odds with the old
1:16:41
dictum of democritus and
1:16:41
lucretius. Nothing can be
1:16:44
created from nothing. If
1:16:44
inflation is right, everything
1:16:49
can be created from nothing, or
1:16:49
at least from very little. If
1:16:53
inflation is right, the universe
1:16:53
can properly be called the
1:16:56
ultimate free lunch and quote,
1:16:56
by Alan Guth and inflation and
1:17:02
the new era of high precision
1:17:02
cosmology 2002.
1:17:08
According to the laws of quantum
1:17:08
mechanics, the quantum
1:17:11
fluctuation that seeded our
1:17:11
universe appeared because it was
1:17:14
possible emerging out of nothing
1:17:14
but the physical laws
1:17:17
themselves. Quote, is there any
1:17:17
bound to how small the initial
1:17:23
universe could be? For my
1:17:23
surprise, I found that the
1:17:27
tunneling probability did not
1:17:27
vanish as the initial size
1:17:30
approached zero. I also noticed
1:17:30
that my calculations were
1:17:35
greatly simplified when I
1:17:35
allowed the initial radius of
1:17:38
the universe to vanish. This was
1:17:38
really crazy. What I had was a
1:17:43
mathematical description of a
1:17:43
universe tunneling from a zero
1:17:46
size from nothing. And yet, the
1:17:46
state of nothing cannot be
1:17:51
identified with absolute
1:17:51
nothingness. The tunneling is
1:17:55
described by the laws of quantum
1:17:55
mechanics, and thus nothing
1:17:58
should be subjected to these
1:17:58
laws. The laws of physics must
1:18:03
have existed even though there
1:18:03
was no universe and quote,
1:18:08
Alexander the Lincoln in many
1:18:08
worlds in one 2006.
1:18:14
General relativity and quantum
1:18:14
mechanics are the two
1:18:18
Cornerstone theories of modern
1:18:18
physics. from them alone, we can
1:18:22
explain a self emerging
1:18:22
universe. Quantum Mechanics
1:18:26
shows how possible fluctuations
1:18:26
spontaneously pop into
1:18:30
existence. General Relativity
1:18:30
explains how such a fluctuation
1:18:35
could expand exponentially to
1:18:35
reach an unfathomable size. See
1:18:40
what caused the Big Bang? But we
1:18:40
must wonder why these laws?
1:18:46
What, if anything, is special
1:18:46
about them? Who or what anointed
1:18:51
these equations with existence?
1:18:51
quote? What is it that breathes
1:18:57
fire into the equations and
1:18:57
makes a universe for them to
1:19:00
describe? The usual approach of
1:19:00
science of constructing a
1:19:05
mathematical model cannot answer
1:19:05
the questions of why there
1:19:08
should be a universe for the
1:19:08
model to describe. Why does the
1:19:12
universe go to all the bother of
1:19:12
existing Stephen Hawking in a
1:19:17
brief history of time 1988.
1:19:21
The idea that the universe is
1:19:21
uncreated or exists due to some
1:19:25
laws predates the successes of
1:19:25
modern physics and cosmology.
1:19:30
The ancient Greeks and Romans
1:19:30
believed that the material of
1:19:34
the universe has always existed,
1:19:34
since nothing comes from
1:19:37
nothing. Quote, the first
1:19:37
principle is that nothing can be
1:19:42
created from the non existent
1:19:42
for otherwise anything would be
1:19:46
formed from anything without the
1:19:46
need of seed. And quote,
1:19:51
Epicurus in letter to Herodotus
1:19:51
circa 300 bc
1:19:57
this matter was originally in a
1:19:57
state of disarray.
1:20:00
Order or chaos. Quotes before
1:20:00
the ocean and the earth appeared
1:20:06
before the skies had over spread
1:20:06
them all. The face of nature in
1:20:09
a vast expanse was not but chaos
1:20:09
uniformly waste of it in
1:20:14
metamorphosis, ad.
1:20:18
It was not until a divine
1:20:18
Craftsman imposed mathematical
1:20:21
order on this chaos that the
1:20:21
ordered universe the cosmos,
1:20:25
appeared in religions with past
1:20:25
eternal cosmologies. The
1:20:30
universe is believed to be
1:20:30
causeless. Jainism explicitly
1:20:34
says the universe was not
1:20:34
created, quote, The doctrine
1:20:40
that the world was created is
1:20:40
ill advised and should be
1:20:43
rejected. If God created the
1:20:43
world, where was he before the
1:20:47
creation? If you say he was
1:20:47
transcendent, then and needed no
1:20:52
support? Where is he now? How
1:20:52
could God have made this world
1:20:56
without any raw material? If you
1:20:56
say that he made this first and
1:21:01
then the world you are faced
1:21:01
with an endless regression, if
1:21:06
you declare that this raw
1:21:06
material arose, naturally you
1:21:09
fall into another fallacy for
1:21:09
the whole universe might have
1:21:12
been its own creator, and have
1:21:12
arisen quite naturally. And
1:21:17
quote, Jean rcnn ma piano 898
1:21:17
ad,
1:21:24
a higher plane. Some suppose our
1:21:24
universe exists on account of a
1:21:29
higher plane and that this
1:21:29
higher plane rather than the
1:21:32
universe is self existent. There
1:21:32
are many conceptions of what
1:21:37
this higher plane of reality is.
1:21:37
Some describe this plane as a
1:21:41
cause of being, be it God, a
1:21:41
creator, Divine Will, a first
1:21:46
cause or an unmoved mover.
1:21:46
Others describe it as a source
1:21:51
of being the mind of God, the
1:21:51
one or the towel. Still others
1:21:56
describe it as a ground of being
1:21:56
the absolute the all or what
1:22:01
Hindus call Brahman. Not all
1:22:01
theories of higher planes of
1:22:05
existence need the supernatural.
1:22:05
There are also naturalistic
1:22:10
descriptions of higher
1:22:10
realities. In multiverse
1:22:14
theories, a higher reality
1:22:14
contains our universe among
1:22:17
others. In brain cosmology, our
1:22:17
universe is caused by collisions
1:22:22
in a literal, higher dimension.
1:22:22
In the simulation hypothesis,
1:22:27
our universe is the result of
1:22:27
computations occurring in a more
1:22:30
fundamental reality. See, are we
1:22:30
living in a computer simulation?
1:22:37
Though these theories deal with
1:22:37
phenomena that are beyond the
1:22:40
nature of our universe, and
1:22:40
hence supernatural evidence is
1:22:44
accumulating for some of these
1:22:44
higher realms. Quote, every
1:22:49
experiment that brings better
1:22:49
credence to inflationary theory
1:22:52
brings us much closer to hints
1:22:52
that the multiverse is real.
1:22:57
Andrei Linde in interview 2014
1:23:01
quotes quote, various theories
1:23:01
imply that various types of
1:23:05
parallel universes exist so that
1:23:05
by modus ponens if we take any
1:23:10
of these theories seriously,
1:23:10
we're forced to take seriously
1:23:13
also some parallel universes.
1:23:13
Parallel Universes aren't a
1:23:18
theory, but predictions of
1:23:18
certain theories. Max Tegmark in
1:23:23
our parallel universes
1:23:23
unscientific nonsense 2014.
1:23:30
The idea of a pre existent
1:23:30
cause, source or ground of being
1:23:34
one that's external to end
1:23:34
beyond our universe is as old as
1:23:38
religion itself. Quote, by means
1:23:38
of the higher knowledge the wise
1:23:44
behold, everywhere, Brahman,
1:23:44
which otherwise cannot be seen,
1:23:47
or seized, which has no root or
1:23:47
attributes, no eyes or ears, no
1:23:52
hands or feet, which is eternal
1:23:52
and omnipresent, all pervading
1:23:57
and extremely subtle, which is
1:23:57
imperishable, and the source of
1:24:01
all beings mundaka Upanishad,
1:24:01
chapter one, verse six, circa
1:24:07
800 BC, quote, In the beginning, God
1:24:10
created the heavens and the
1:24:14
earth. Genesis chapter one verse

1:24:21
Consciousness, some posits that
1:24:21
consciousness is self existent,
1:24:27
if true consciousness could be
1:24:27
the cause of a universe that
1:24:30
exists only in appearance. The
1:24:30
idea seems strange, but we must
1:24:36
admit all knowledge of existence
1:24:36
comes to us through experiences
1:24:39
that exist in our conscious
1:24:39
minds. This fact hasn't escaped
1:24:44
the attention of scientists.
1:24:44
Quote, it is difficult for the
1:24:49
matter of fact physicist to
1:24:49
accept the view that the
1:24:52
substratum of everything is of
1:24:52
mental character, but no one can
1:24:57
deny that mind is the first and
1:24:57
most
1:25:00
Direct thing in our experience
1:25:00
and all else is remote
1:25:03
inference. And quote, Arthur
1:25:03
Eddington in the nature of the
1:25:08
physical world 1927.
1:25:12
Quote, I regard consciousness as
1:25:12
fundamental. I regard matter as
1:25:19
derivative from consciousness.
1:25:19
We cannot get behind
1:25:23
consciousness, everything that
1:25:23
we talk about everything that we
1:25:27
regard as existing postulates
1:25:27
consciousness. And quote, Max
1:25:33
Planck in interviews with great
1:25:33
scientists 1931
1:25:39
the relation between Mind and
1:25:39
Matter perplexes scientists to
1:25:42
this day, it leads to
1:25:42
philosophical conundrums like
1:25:46
brains in a vat Boltzmann brains
1:25:46
and the simulation argument, all
1:25:52
of which suppose that perceived
1:25:52
reality is an illusion, a
1:25:55
byproduct of a deluded mind.
1:25:55
It's also led physicists to
1:26:00
propose theories where conscious
1:26:00
minds play a fundamental role in
1:26:04
shaping reality as we see it.
1:26:04
Physics, after all, is
1:26:09
fundamentally about experiences.
1:26:09
Physics is the science of
1:26:13
predicting future observations
1:26:13
from prior observations. In
1:26:18
1970, Heinz dtsa proposed the
1:26:18
many minds interpretation of
1:26:22
quantum mechanics, which
1:26:22
proposes that differentiation of
1:26:26
an infinity of observer mind
1:26:26
states explains quantum
1:26:29
phenomena. Quote, a many minds
1:26:29
theory, like a many worlds
1:26:35
theory, suppose is that
1:26:35
associated with a sentient being
1:26:39
at any given time, there is a
1:26:39
multiplicity of distinct
1:26:42
conscious points of view. But a
1:26:42
many minds theory holds that it
1:26:46
is these conscious points of
1:26:46
view all minds, rather than
1:26:50
worlds that are to be conceived
1:26:50
as literally dividing or
1:26:53
differentiating over time.
1:26:53
Michael Lockwood in many minds,
1:26:58
interpretations of quantum
1:26:58
mechanics 1995
1:27:04
the mysterious link between
1:27:04
consciousness and reality
1:27:07
inspired john wheelers idea of a
1:27:07
participatory universe, as
1:27:12
Martin Redfern described, many
1:27:12
don't agree with john Wheeler.
1:27:15
But if he's right then we and
1:27:15
presumably other conscious
1:27:18
observers throughout the
1:27:18
universe are the creators, or at
1:27:22
least the minds that make the
1:27:22
universe manifest. The idea that
1:27:26
consciousness proceeds the
1:27:26
material world has a rich
1:27:30
history. It is found across
1:27:30
philosophies and religious
1:27:34
traditions, where physical
1:27:34
reality is seen as a dream or
1:27:38
construct of a mind or soul.

1:27:44

1:27:53
A few millennia later, the
1:27:53
philosopher George Berkeley
1:27:56
echoed poem and it is concluding
1:27:56
that to be is to be perceived.
1:28:00
Quote, it is indeed widely
1:28:00
believed that all perceptible
1:28:05
objects, houses, mountains,
1:28:05
rivers, and so on, really exist
1:28:10
independently of being perceived
1:28:10
by the understanding. But
1:28:14
however widely and confidently,
1:28:14
this belief may be held, anyone
1:28:18
who has the courage to challenge
1:28:18
it will, if I'm not mistaken,
1:28:21
see that it involves an obvious
1:28:21
contradiction for what our
1:28:26
houses, mountains, rivers, etc,
1:28:26
but things we perceive by sense,
1:28:31
and quote, George Berkeley in
1:28:31
the principles of human
1:28:36
knowledge 1710. Hindus believe the universal
1:28:39
mind or world soul Atman became
1:28:44
the universe. Accordingly, the
1:28:44
universe is not real, but the
1:28:48
dream of a god under the spell
1:28:48
of Maya, a temporary ignorance
1:28:52
of the true reality. Buddhists
1:28:52
believe that the mind underlies
1:28:57
and forms everything. Quote, all
1:28:57
the phenomena of existence of
1:29:03
mind as their precursor mind as
1:29:03
their Supreme Leader, and of
1:29:06
mind are they made, end quote,
1:29:06
Gautama Buddha in the dhammapada
1:29:12
circa 500 BC, the Taoist philosopher Zhu ang
1:29:16
Jo said the world is a dream,
1:29:20
quote, while he is dreaming, he
1:29:20
does not know it is a dream. And
1:29:25
in his dream, he may even try to
1:29:25
interpret a dream. Only after he
1:29:30
wakes does he know it was a
1:29:30
dream. And someday there will be
1:29:34
a great awakening when we know
1:29:34
that this is all a great dream.
1:29:39
And quote, Zhu ng Joe and join z
1:29:39
circa 300 BC.
1:29:46
Reviewing answers, we've
1:29:46
considered seven proposals for
1:29:50
self existence things, logic,
1:29:50
truth, numbers, possibility
1:30:00
The universe, a higher plane,
1:30:00
and consciousness. yet so far,
1:30:07
none of these is satisfactory as
1:30:07
an ultimate explanation. None
1:30:12
stands out as a final because
1:30:12
that doesn't throw up a further
1:30:15
Why? abstract entities, logic,
1:30:15
truth numbers. First, we have
1:30:23
abstract entities, logic, truth
1:30:23
and numbers. But though these
1:30:28
things are plausibly causeless,
1:30:28
how could they cause anything?
1:30:33
These things are eternal and
1:30:33
unchanging, not to mention
1:30:36
abstract, how can they cause
1:30:36
anything like the huge dynamic
1:30:41
universe we see, quote, so the
1:30:41
cause of the universe must at
1:30:46
least causally prior to the
1:30:46
universe's existence transcends
1:30:50
space and time and therefore
1:30:50
cannot be physical or material.
1:30:55
But there are only two kinds of
1:30:55
things that could fall under
1:30:58
such a description, either an
1:30:58
abstract object, like a number,
1:31:02
or else a mind, a soul, a self.
1:31:02
But abstract objects don't stand
1:31:08
in causal relations. This is
1:31:08
part of what it means to be
1:31:12
abstract. The number seven, for
1:31:12
example, doesn't cause anything.
1:31:18
And quote, William Lane Craig in
1:31:18
reasonable faith, 1994.
1:31:25
possibility, mathematical
1:31:25
consistency. What about all
1:31:30
possibility? If all possible
1:31:30
things exist, then our universe
1:31:35
would be counted among those
1:31:35
possible things? But why should
1:31:39
possible things be actual, as
1:31:39
JJC smart remarked that anything
1:31:44
should exist at all does seem to
1:31:44
me a matter for the deepest or
1:31:49
existence is what we seek to
1:31:49
explain. And there is another
1:31:54
issue, why is our universe so
1:31:54
simple and ordered compared to
1:31:58
all else that exists in the
1:31:58
space of all possibility? quote,
1:32:03
Tegmark proposal, however, faces
1:32:03
a formidable problem. The number
1:32:09
of mathematical structures
1:32:09
increases with increasing
1:32:12
complexity, suggesting the
1:32:12
typical structures should be
1:32:15
horrendously large and
1:32:15
cumbersome. This seems to be in
1:32:19
conflict with the simplicity and
1:32:19
beauty of the theories
1:32:22
describing our world. Alexander
1:32:22
the Lincoln in many worlds in
1:32:27
one 2006,
1:32:30
the physical, the universe,
1:32:30
physical law, if the universe
1:32:36
alone exists, it explains
1:32:36
exactly what we see. But there
1:32:41
would be lingering questions.
1:32:41
Why does consciousness exist?
1:32:46
are abstract entities real? And
1:32:46
perhaps the biggest mystery of
1:32:50
all? Why should this universe or
1:32:50
its laws be the only real ones?
1:32:56
As Lee Smolin asked, Why do
1:32:56
these laws and not others hold
1:33:01
in our universe? Does the
1:33:01
existence of laws require some
1:33:05
higher principle? quote,
1:33:05
although science may solve the
1:33:11
problem of how the universe
1:33:11
began, it cannot answer the
1:33:14
question. Why does the universe
1:33:14
bother to exist? Maybe only God
1:33:19
can answer that. Stephen Hawking
1:33:19
in interview 1988
1:33:26
hyperplanes God multiverse
1:33:26
simulation, we might appeal to a
1:33:32
higher cause to explain the
1:33:32
universe we see. But as JJC
1:33:37
smart reminds us if we postulate
1:33:37
God, in addition to the created
1:33:41
universe, we increase the
1:33:41
complexity of our hypothesis. We
1:33:46
have all the complexity of the
1:33:46
universe itself. And we have In
1:33:49
addition, the at least equal
1:33:49
complexity of God. This seems
1:33:53
true for any higher principle.
1:33:53
For example, if we presume our
1:33:58
universe is the result of a
1:33:58
simulation in a higher reality,
1:34:02
what's responsible for that
1:34:02
higher reality? quote, whatever
1:34:08
our final theory of physics, we
1:34:08
will be left facing an
1:34:11
irreducible mystery. For perhaps
1:34:11
there could have been nothing at
1:34:15
all. Not even empty space, but
1:34:15
just absolutely nothing. If you
1:34:21
believe God is the Creator,
1:34:21
well, why is God that way? The
1:34:26
religious person is left with a
1:34:26
mystery which is no less than
1:34:30
the mystery with which science
1:34:30
leaves us. End quote. Steven

1:34:50
is causeless, it could explain

why perceptions exist. But if

reality is only a dream or
1:34:55
illusion, why do our perceptions
1:34:59
appear to follow Long with the universe adhering

everything in this universe were
1:35:10

1:35:27
causeless cause what we seek and
1:35:27
have so far have failed to
1:35:32
identify is a causeless cause.
1:35:32
This is something that not only
1:35:37
has a plausibly self existence
1:35:37
and causeless nature, but also
1:35:41
plausibly accounts for the
1:35:41
reality we see. We find things
1:35:46
that appear to be causeless,
1:35:46
logic, truth, and numbers, but
1:35:50
these things also appear in
1:35:50
capable of being a cause.
1:35:54
Conversely, we found things that
1:35:54
could be a cause the universe, a
1:35:59
higher plane and consciousness,
1:35:59
but they don't seem causeless
1:36:04
then there is possibility for
1:36:04
which we have reason to question
1:36:07
whether it is causeless and
1:36:07
whether it causes what we see,
1:36:11
we find an almost inverse
1:36:11
relation, the more plausibly
1:36:15
something is causeless, the less
1:36:15
plausible it seems to be the
1:36:18
cause for what we see. causeless
1:36:18
cause would provide us with a
1:36:23
complete explanation. It will
1:36:23
explain both itself and the
1:36:27
properties of observed reality.
1:36:27
It will describe the relation
1:36:31
between the mental and material.
1:36:31
It will tell us why the universe
1:36:36
exists and why it has simple
1:36:36
ordered laws. to progress we
1:36:40
need to find the connecting glue
1:36:40
the missing piece of the puzzle
1:36:44
that shows either how a
1:36:44
causeless thing accounts for the
1:36:47
reality we see or alternatively,
1:36:47
why the reality we see is
1:36:51
causeless three modes of
1:36:51
existence. In reviewing the
1:36:56
seven categories of possibly
1:36:56
costless things, we encountered
1:36:59
three modes of existence,
1:36:59
loosely speaking they are
1:37:05
mathematical existence, material existence, and mental
1:37:08
existence. Mathematical
1:37:15
existence includes abstract
1:37:15
entities, logic, truth, numbers,
1:37:20
math, properties, forms,
1:37:20
equations, relations,
1:37:24
possibility, structures, laws,
1:37:24
and principles. This mode might
1:37:30
include religious concepts of
1:37:30
divine law will order, Tao, or
1:37:35
logos, the infinite indivisible
1:37:35
truth, Ashoka vendor and divine
1:37:40
mathematics. material existence
1:37:40
includes matter, energy, the
1:37:45
vacuum, spacetime, physical law,
1:37:45
the universe, the multiverse
1:37:51
particles, forces, fields, and
1:37:51
physical systems. This mode
1:37:56
might include what religions
1:37:56
refer to as creation, cosmos,
1:37:59
the material plane, and Maya or
1:37:59
illusion. Mental existence
1:38:04
includes mind consciousness,
1:38:04
observations, perceptions,
1:38:09
ideas, and dreams. This mode
1:38:09
might include religious concepts
1:38:15
of the mind of God, world, soul,
1:38:15
art man, and souls or spirits.
1:38:20
What is the relation between the
1:38:20
three modes of existence, math,
1:38:25
matter and mind? quote, my
1:38:25
viewpoint allows for three
1:38:30
different kinds of reality, the
1:38:30
physical, the mental, and the
1:38:34
platonic mathematical with
1:38:34
something as yet profoundly
1:38:38
mysterious in the relations
1:38:38
between the three. Roger Penrose
1:38:43
in the big questions, what is
1:38:43
reality? 2006
1:38:50
math matter, mind, of the three
1:38:50
modes of existence does any
1:38:55
stand out as being more
1:38:55
fundamental than any of the
1:38:58
others? What is their relation?
1:38:58
If one of these modes of
1:39:03
existence can be shown as
1:39:03
primary while the others are
1:39:06
derivative, then we might close
1:39:06
in on a causeless cause. A
1:39:11
common view of physicists is
1:39:11
that matter produces mind and
1:39:15
mind produces math. But even
1:39:15
among physicists, this view
1:39:19
isn't universal. Quote. The
1:39:19
triangle suggests the
1:39:25
circularity of the widespread
1:39:25
view that math arises from the
1:39:28
mind the mind that arises out of
1:39:28
matter, and that matter can be
1:39:31
explained in terms of math. Non
1:39:31
physicists should be wary of any
1:39:36
claim that modern physics leads
1:39:36
us to any particular resolution
1:39:40
of this circularity. Since even
1:39:40
the sample of three theoretical
1:39:43
physicists writing this paper
1:39:43
hold three divergent views. And
1:39:48
quote, Pizza Hut, Mark Alford
1:39:48
and Max Tegmark in on math
1:39:53
matter and mind 2006
1:39:58
what is the reality of These modes of existence are all
1:40:00
on equal footing, or is one more
1:40:05
fundamental while the others are
1:40:05
derivative. materialism matter
1:40:11
is primary. materialism is the
1:40:11
view that matter is fundamental.
1:40:17
It assumes mental states are the
1:40:17
byproduct of particular material
1:40:21
arrangements, for example,
1:40:21
brains, and that mathematical
1:40:24
objects, if they exist at all
1:40:24
outside of minds have no bearing
1:40:29
on the material world.
1:40:29
materialism is a popular if not
1:40:34
conventional view among
1:40:34
physicists. materialism can
1:40:39
explain why our perceptions
1:40:39
follow the patterns of physical
1:40:42
law, but it has difficulty
1:40:42
explaining why matter gives rise
1:40:45
to mental states. This is the so
1:40:45
called hard problem of
1:40:49
consciousness. materialism also
1:40:49
hits an explanatory dead end
1:40:54
trying to answer why matter
1:40:54
exists and why it follows simple
1:40:57
physical laws. Quote, if he gets
1:40:57
to know the worlds structure,
1:41:04
asked the scientists, science,
1:41:04
however, seems unable to answer
1:41:09
some key questions concerning
1:41:09
the structure. For start, why is
1:41:14
the structure an orderly one?
1:41:14
Why do events so often develop
1:41:18
in fairly simple and familiar
1:41:18
ways leading us to talk of
1:41:22
causal laws? Then there is what
1:41:22
can seem the biggest question of
1:41:27
all, science investigates the
1:41:27
world's structure, but why is
1:41:32
there anything at all to be
1:41:32
structured? Why is there a
1:41:35
Cosmos? Not a blank? Why is
1:41:35
there something rather than
1:41:40
nothing? Science cannot answer
1:41:40
this. JOHN Leslie and a Cosmos
1:41:46
existing through ethical
1:41:46
necessity 2000 that Ben's nine
1:41:51
idealism mind his primary
1:41:51
idealism is the view that mind
1:41:57
is fundamental. It assumes
1:41:57
mental states are the basis of
1:42:01
reality, and that the matter
1:42:01
that seems to exist exists only
1:42:05
as thoughts and perceptions in
1:42:05
minds, idealism as expressed by
1:42:10
Eastern religions, theologians,
1:42:10
and mystics, but increasingly,
1:42:16
physicists recognize they can't
1:42:16
so easily do away with the
1:42:19
observer. It seems the observer
1:42:19
plays a necessary if not
1:42:24
fundamental role in any
1:42:24
description of reality, quote,
1:42:29
consciousness cannot be
1:42:29
accounted for in physical terms
1:42:33
for consciousness is absolutely
1:42:33
fundamental. It cannot be
1:42:38
accounted for in terms of
1:42:38
anything else. And quote, Erwin
1:42:43
Schrodinger in interview 1931.
1:42:47
But idealism doesn't answer
1:42:47
everything. He doesn't explain
1:42:52
why minds are bound up with the
1:42:52
patterns of matter in a material
1:42:55
world. Quote, we find that our
1:42:55
perceptions obey some laws,
1:43:01
which can be most conveniently
1:43:01
formulated if we assume that
1:43:04
there is some underlying reality
1:43:04
beyond our perceptions. This
1:43:09
model of a material world
1:43:09
obeying laws of physics is so
1:43:12
successful that soon we forget
1:43:12
about our starting point and say
1:43:16
that matter is the only reality
1:43:16
and perceptions are nothing but
1:43:19
a useful tool for the
1:43:19
description of matter. This
1:43:23
assumption is almost as natural
1:43:23
and maybe as false as our
1:43:27
previous assumption that space
1:43:27
is only a mathematical tool for
1:43:31
the description of matter. We
1:43:31
are substituting reality of our
1:43:35
feelings by the successfully
1:43:35
working theory of an
1:43:37
independently existing material
1:43:37
world. And the theory is so
1:43:42
successful that we almost never
1:43:42
think about its possible
1:43:45
limitations. And quote, Andrei
1:43:45
Linde in inflation, quantum
1:43:51
cosmology and the anthropic
1:43:51
principle 2002
1:43:57
platonism. Math is primary
1:43:57
platonism is the idea that math
1:44:02
is fundamental. It assumes
1:44:02
abstract objects are the most
1:44:07
real, and that everything we see
1:44:07
and perceive is somehow
1:44:10
derivative from this higher
1:44:10
existence. platonism is popular
1:44:15
among philosophers and
1:44:15
mathematicians whose job is to
1:44:18
study the objective properties
1:44:18
of abstract things. If
1:44:22
mathematical objects form the
1:44:22
basis of reality, it might
1:44:26
explain why the material world
1:44:26
is so mathematical in its form.
1:44:30
Quote, in a famous 1959 lecture,
1:44:30
physicist Eugene p Wigner,
1:44:36
argued that the enormous
1:44:36
usefulness of mathematics in the
1:44:39
natural sciences is something
1:44:39
bordering on the mysterious
1:44:44
conversely, mathematical
1:44:44
structures have an eerily real
1:44:47
feel to them. They satisfy a
1:44:47
central criterion of objective
1:44:52
existence, they are the same no
1:44:52
matter who studies them. A
1:44:56
theorem is true regardless of
1:44:56
whether it is proved by a human
1:45:00
A computer or an intelligent
1:45:00
dolphin, contemplative alien
1:45:05
civilizations would find the
1:45:05
same mathematical structures as
1:45:09
we have. Accordingly,
1:45:09
mathematicians commonly say that
1:45:13
they discover mathematical
1:45:13
structures rather than create
1:45:16
them. Max Tegmark in parallel
1:45:16
universes 2003
1:45:23
where platonism falls short is
1:45:23
in explaining how abstract
1:45:27
objects lead to material or
1:45:27
mental existence. According to
1:45:31
lightness, the difficulty is
1:45:31
explaining how from eternal or
1:45:35
essential metaphysical truths
1:45:35
there arise temporal contingent
1:45:39
or physical truths. What came
1:45:39
first, for each of the three
1:45:44
modes of existence, there is an
1:45:44
ancient school of thought
1:45:48
holding that mode of existence
1:45:48
as most fundamental. The
1:45:52
mathematical, Plato believed
1:45:52
that abstract entities were the
1:45:56
most real, and that the material
1:45:56
world was derivative. The
1:46:00
material Plato's foremost
1:46:00
student, Aristotle, disagreed,
1:46:05
saying material substances were
1:46:05
more real than abstract forms.
1:46:10
The mental several centuries
1:46:10
later, plotinus argued that mind
1:46:14
was more real than the material
1:46:14
reality it perceives. Today's
1:46:19
scientists, mathematicians, and
1:46:19
philosophers seem no closer to
1:46:23
an answer on whether math matter
1:46:23
or mind came first.
1:46:29
Does mind give rise to math? Or
1:46:29
does math give rise to mind?
1:46:34
does matter give rise to mind?
1:46:34
Or does mind give rise to
1:46:38
matter? Does math give rise to matter?
1:46:40
Or does matter give rise to
1:46:43
math? to unravel? The mystery of
1:46:43
existence requires that we
1:46:48
understand the relationship
1:46:48
between these modes of
1:46:50
existence. Only then do we have
1:46:50
any hope of identifying an
1:46:55
ultimate explanation or
1:46:55
causeless cause, quote, to
1:47:00
address the nature of reality,
1:47:00
we need to understand its
1:47:03
connection to consciousness and
1:47:03
mathematics. And, quote, Roger
1:47:10
Penrose in the big questions,
1:47:10
what is reality? 2006
1:47:17
are they one, various thinkers
1:47:17
have suspected the three modes
1:47:22
of existence to be connected and
1:47:22
perhaps are all aspects of one
1:47:25
ultimate reality, Mind and
1:47:25
Matter as one. Modern physical
1:47:31
experiments have revealed
1:47:31
something inseparable between
1:47:34
the mind and the observed
1:47:34
physical reality. Quote, as we
1:47:39
penetrate into matter, nature
1:47:39
does not show as any isolated
1:47:43
basic building blocks, but
1:47:43
rather appears as a complicated
1:47:47
web of relations between the
1:47:47
various parts of the hole. These
1:47:51
relations always include the
1:47:51
observer in an essential way,
1:47:55
the human observer constitutes
1:47:55
the final link in the chain of
1:47:59
observational processes, and the
1:47:59
properties of any atomic object
1:48:03
can only be understood in terms
1:48:03
of interaction with the
1:48:06
observer. This means that the
1:48:06
classical ideal of an objective
1:48:10
description of nature is no
1:48:10
longer valid. The Cartesian
1:48:14
partition between the eye and
1:48:14
the world between the observer
1:48:17
and the observed cannot be made
1:48:17
when dealing with atomic matter.
1:48:22
In atomic physics, we can never
1:48:22
speak about nature without at
1:48:26
the same time speaking about
1:48:26
ourselves fritjof Capra and the
1:48:31
Tao of physics 1975.
1:48:35
Quote, aren't we mistaken in
1:48:35
making this separation between
1:48:40
the universe and life and the
1:48:40
mind? Sugar we seek ways to
1:48:44
think of them as one. JOHN

Math and matter as one.
1:48:53
Likewise, mathematicians and
1:48:58
scientists cannot help but
1:48:58
notice a mysterious link
1:49:01
connecting mathematics and the
1:49:01
physical world. Quote, there
1:49:07
exists unless I am mistaken, an
1:49:07
entire world consisting of the
1:49:11
totality of mathematical truths,
1:49:11
which is accessible to us only
1:49:15
through our intelligence, just
1:49:15
as there exists the world of
1:49:18
physical realities. Each one is
1:49:18
independent of us, both of them
1:49:23
divinely created and appear
1:49:23
different only because of the
1:49:26
weakness of our mind. But for a
1:49:26
more powerful intelligence, they
1:49:32
are one and the same thing whose
1:49:32
synthesis is partially revealed
1:49:35
in that marvelous correspondence
1:49:35
between abstract mathematics on
1:49:39
the one hand, and astronomy and
1:49:39
all branches of physics on the
1:49:42
other. End quote, Charles a

are all that exist. Maybe the

world, the physical world and
1:51:07
the mathematical world? On the
1:51:12
unarguable assumption that the
1:51:12
principle underlying Ultimate
1:51:15
Reality is radically simple? It
1:51:15
will here be conjectured that
1:51:18
these three realms are one and
1:51:18
the same under different
1:51:21
descriptions. David psny, does
1:51:21
anything exist in 1995?
1:51:29
a path to reality. For
1:51:29
millennia, philosophers have
1:51:34
debated the relation between
1:51:34
math matter and mind. For
1:51:38
millennia, they've sought a
1:51:38
causeless cause. Despite this,
1:51:43
philosophy has not yielded any
1:51:43
definitive answers. Perhaps
1:51:48
science can shed new light on
1:51:48
this question. Science allows us
1:51:53
to test and decide among
1:51:53
competing theories, science
1:51:56
provides opportunities to
1:51:56
discover the missing piece of
1:51:59
the puzzle and explain how and
1:51:59
why a causeless thing gives rise
1:52:03
to the reality we see. As it
1:52:03
happens, discoveries in the
1:52:07
field of mathematics in the 20th
1:52:07
century found this missing
1:52:11
puzzle piece. We now know a
1:52:11
viable link between eternal or
1:52:15
essential metaphysical truths
1:52:15
and temporal contingent or
1:52:19
physical truths. We can explain
1:52:19
how reality can emerge from self
1:52:24
existent causeless truth
1:52:24
concerning numbers and their
1:52:27
relations. But without hard
1:52:27
science and observational
1:52:31
evidence to back it up, how can
1:52:31
we ever know if this explanation
1:52:34
is right? How can we ever escape
1:52:34
from the morass of inconclusive
1:52:39
philosophy? Fortunately,
1:52:39
discoveries in the fields of
1:52:43
physics and cosmology, also
1:52:43
occurring in the 20th century
1:52:47
provide exactly this support. We
1:52:47
not only have found a plausible
1:52:52
path to reality, we have
1:52:52
evidence for it. 20th century
1:52:56
mathematics many consider the
1:52:56
field of mathematics to be
1:53:01
mostly uneventful unchanged,
1:53:01
since you could define the laws
1:53:05
of geometry 2300 years ago, but
1:53:05
at the turn of the 20th century,
1:53:11
the field of mathematics was in
1:53:11
a state of crisis. The field was
1:53:15
shaken to its foundation. Math
1:53:15
was broken, and it had to be
1:53:20
rebuilt from scratch. During
1:53:20
this reformation, monumental
1:53:24
discoveries shocked and dismayed
1:53:24
mathematicians. In the first
1:53:29
half of the 20th century,
1:53:29
logicians and mathematicians
1:53:33
discovered a provably self
1:53:33
existence thing. In the second
1:53:37
half of the 20th century, they
1:53:37
showed how, under certain
1:53:40
assumptions, this self existence
1:53:40
thing could account for the
1:53:44
reality we see. Mike this thing
1:53:44
the causeless cause. Let's see
1:53:51
what mathematicians found and
1:53:51
how they came to find it. The
1:53:55
foundational crisis. At the turn
1:53:55
of the 20th century, math was in
1:54:01
trouble. It was undergoing what
1:54:01
came to be called the
1:54:04
foundational crisis of
1:54:04
mathematics. At the time, set
1:54:09
theory had come to serve as the
1:54:09
foundation of mathematics. All
1:54:13
mathematical proofs ultimately
1:54:13
relied on it. But in 1899, Ernst
1:54:19
sumela noticed this set theory
1:54:19
had a fatal flaw. The Melo told
1:54:24
other math professors at the
1:54:24
University of getting in about
1:54:26
it, including David Hilbert, but
1:54:26
tumelo didn't publish it. In
1:54:31
1901 Bertrand Russell also
1:54:31
noticed this flaw, but Russell
1:54:37
didn't stay quiet. He wrote a
1:54:37
letter in 1902 to gottlob frager
1:54:42
just as his second volume on set
1:54:42
theory was going off to the
1:54:45
publisher frager had spent
1:54:45
decades laying the foundation of
1:54:50
set theory. It was his life's
1:54:50
work, but one letter showing one
1:54:55
flaw brought it all down.
1:54:55
Russell showed frager
1:55:00
Set Theory allows two
1:55:00
contradictory statements to both
1:55:03
be proved. This flaw is known as
1:55:03
Russell's paradox. one flaw
1:55:09
might not sound so bad, but in
1:55:09
math it is fatal. For if in
1:55:13
math, just one false hood can be
1:55:13
proved, then any false hood can
1:55:18
be proved. This is known as the
1:55:18
principle of explosion. For
1:55:23
example, assume mathematics had
1:55:23
a flaw that allowed you to prove
1:55:27
that two plus two equals five.
1:55:27
You could use this false proof
1:55:32
to prove anything, you could
1:55:32
prove that the $1 in your bank
1:55:36
account equals $1 million. Starting with two plus two
1:55:39
equals five, subtract four from
1:55:44
both sides, then you get zero
1:55:44
equals one. Now multiply both
1:55:49
sides by 999,999. Then you get
1:55:49
zero equals 999,999. Now add one
1:56:02
to both sides. You have now
1:56:02
proven one equals 1 million. If
1:56:08
mathematic proofs have false
1:56:08
statements, then contracts,
1:56:11
commerce, even society as we
1:56:11
know it couldn't function. This
1:56:16
was the state of mathematics in
1:56:16
1900. It's no wonder it was
1:56:20
considered a crisis. Math was
1:56:20
broken. It had to be fixed. It
1:56:27
needed a rallying cry, a call to
1:56:27
action. In 1900, mathematicians
1:56:34
from around the world gathered
1:56:34
in Paris for the International
1:56:37
Congress of Mathematicians,
1:56:37
David Hilbert considered the
1:56:42
greatest mathematician of his
1:56:42
time was invited to speak, he
1:56:46
used the opportunity to present
1:56:46
what he considered to be the 23
1:56:50
most significant open problems
1:56:50
in mathematics. The second of
1:56:55
Hilbert problems call for a
1:56:55
proof that the foundational
1:56:58
rules of mathematics were free
1:56:58
of contradictions. This would
1:57:03
once and for all, put math on a
1:57:03
solid foundation. Never again
1:57:08
would mathematicians need worry
1:57:08
that a new contradiction might
1:57:11
one day surface and torpedo the
1:57:11
whole of mathematics, new
1:57:16
foundations, the collapse of
1:57:16
fraters set theory and Hilbert
1:57:21
score for a provably solid
1:57:21
foundation for math served as an
1:57:25
inspiration. Under Hilbert
1:57:25
direction as a mellow began work
1:57:30
on fixing set theory. Similarly,
1:57:30
Bertrand Russell began work with
1:57:35
his supervisor, Alfred North
1:57:35
Whitehead on a solution. Their
1:57:40
aim was to lay a new foundation
1:57:40
for mathematics based on a
1:57:44
precise logic and produce a set
1:57:44
theory rid of paradoxes and
1:57:47
contradictions. It was a massive
1:57:47
undertaking that took over a
1:57:52
decade. It culminated in the
1:57:52
three volume tome Principia
1:57:56
Mathematica, published in
1:57:56
1910 1912, and 1913. It was so
1:58:03
detailed that it famously
1:58:03
required several 100 pages to
1:58:06
work up to the point where it
1:58:06
proved one plus one equals two.
1:58:11
Owing to its complexity and
1:58:11
unique notation, Principia
1:58:14
Mathematica never gained much
1:58:14
popularity with mathematicians.
1:58:19
It also had a competitor. By
1:58:19
1908, sumela developed a new set
1:58:25
theory consisting of just eight
1:58:25
rules, and in 1921, it was
1:58:31
further improved by Abraham
1:58:31
Frankel. Their combined result
1:58:35
is called a mellow Fraenkel set
1:58:35
theory. It became the default
1:58:40
foundation of mathematics and
1:58:40
remains so to this day Hilbert
1:58:45
program. Although no one had
1:58:45
discovered contradictions in
1:58:49
either Russell's also melos new
1:58:49
foundational systems, no one had
1:58:53
been able to prove they were
1:58:53
free of contradictions either.
1:58:57
Mathematics still rested on a
1:58:57
foundation of uncertain
1:59:01
stability. This led Hilbert in
1:59:01
1921, to push for finding a
1:59:06
mathematical theory that was
1:59:06
provably consistent. And not
1:59:11
only did he want this theory to
1:59:11
be provably consistent, he
1:59:14
wanted it to be provably
1:59:14
complete. A complete system of
1:59:18
mathematics means any true
1:59:18
statement can be proven within
1:59:22
that theory. There would never
1:59:22
be a need to add to this
1:59:25
complete theory, as it would
1:59:25
cover everything that
1:59:28
mathematicians might think up in
1:59:28
the future. It would be a final
1:59:32
theory and the last theory any
1:59:32
mathematician would ever need.
1:59:37
It was the mathematicians
1:59:37
equivalent of a theory of
1:59:39
everything, where all of
1:59:39
mathematics is derived from one
1:59:43
rock solid foundation. The
1:59:43
effort to find this theory
1:59:47
became known as Hilbert program.
1:59:47
It was a noble goal. but less
1:59:53
than a decade after launching
1:59:53
his program, Hilbert stream of a
1:59:57
final theory was shattered In 1930, at a conference in Kern
2:00:00
expec, Hilbert remained
2:00:04
confident in the eventual
2:00:04
success of his program
2:00:06
proclaiming the moves and vison
2:00:06
via Verdun vison, we must know
2:00:13
we will know. The phrase would
2:00:13
later be Hilbert epitaph girdles
2:00:19
incompleteness theorems. Unknown
2:00:19
to Hilbert, his dream had
2:00:24
already been crushed the day
2:00:24
before. At the very same
2:00:28
conference, the 24 year old Kurt
2:00:28
girdle presented his PhD thesis,
2:00:34
it proved Hilbert stream is
2:00:34
impossible. at the conference
2:00:38
girdle presented his first
2:00:38
incompleteness theorem. It
2:00:42
showed that in any finite
2:00:42
mathematical Foundation, there
2:00:46
will be true statements that
2:00:46
can't be proved in that theory.
2:00:50
Thus Hilbert stream of
2:00:50
completeness is impossible.
2:00:54
Quote, the most comprehensive
2:00:54
current formal systems are the
2:00:58
system of Principia Mathematica
2:00:58
pm on the one hand, there's a
2:01:03
mellow Frank Elian AXIOM system
2:01:03
of set theory. On the other
2:01:06
hand, these two systems are so
2:01:06
far developed that you can
2:01:10
formalize in them all proof
2:01:10
methods that are currently in
2:01:13
use in mathematics, ie you can
2:01:13
reduce these proof methods to a
2:01:17
few axioms and deduction rules.
2:01:17
Therefore, the conclusion seems
2:01:22
plausible that these deduction
2:01:22
rules are sufficient to decide
2:01:26
all mathematical questions
2:01:26
expressible in those systems, we
2:01:30
will show that this is not true.
2:01:30
And quote, Kurt girdle in on
2:01:36
formerly undecidable
2:01:36
propositions of Principia
2:01:39
Mathematica and related systems.
2:01:39
119 31.
2:01:44
girdles first incompleteness
2:01:44
theorem showed there could never
2:01:48
be a final theory that would
2:01:48
serve mathematicians for all
2:01:51
time, girdle wasn't finished.
2:01:51
Shortly thereafter, he published
2:01:57
his second incompleteness
2:01:57
theorem. This proved that no
2:02:01
consistent theory of mathematics
2:02:01
can ever prove itself to be
2:02:04
consistent. The second of
2:02:04
Hilbert 23 problems was
2:02:08
impossible. This explained the
2:02:08
failure of the Melo improving
2:02:13
the consistency of his set
2:02:13
theory. It was actually a good
2:02:17
sign that he was unable to had
2:02:17
he been able to prove it
2:02:20
consistent, it would imply that
2:02:20
it was not. So now, not only was
2:02:25
completeness impossible, but it
2:02:25
was also impossible for a theory
2:02:29
to prove its own consistency.
2:02:29
This was a double whammy to
2:02:33
Hilbert. Hilbert lived another
2:02:33
12 years but he never publicly
2:02:38
acknowledged girdles result.
2:02:38
privately, he was crushed. He
2:02:43
didn't want mathematics to be
2:02:43
this way. But others greatly
2:02:47
admired girdle and his
2:02:47
achievement. When Harvard gave
2:02:51
girdle an honorary degree, he
2:02:51
was introduced as the discoverer
2:02:55
of the most significant
2:02:55
mathematical truth in the
2:02:57
century. Some are called girdle
2:02:57
the greatest logician since
2:03:01
Aristotle. Edward Nelson called
2:03:01
Aristotle the greatest logician
2:03:06
before girdle. JOHN von Neumann
2:03:06
said girdle is absolutely
2:03:11
irreplaceable. He is the only
2:03:11
mathematician alive about whom I
2:03:15
would dare make this statement.
2:03:15
Einstein and girdle both worked
2:03:20
at the Institute for Advanced
2:03:20
Study. Near the end of his life,
2:03:24
Einstein confided to Oskar
2:03:24
Morgenstern that his own work no
2:03:28
longer meant much that he came
2:03:28
to the institute merely to have
2:03:31
the privilege of walking home
2:03:31
with girdle undecidability. In
2:03:37
1673, libraries invented and
2:03:37
later built the first digital
2:03:42
calculator, he declared, it is
2:03:42
beneath the dignity of excellent
2:03:46
men to waste their time in
2:03:46
calculation when any peasant
2:03:50
could do the work just as
2:03:50
accurately with the aid of a
2:03:52
machine. After he built the
2:03:52
device likeness began to wonder
2:03:57
about the limits of what
2:03:57
machines can calculate. Was it
2:04:00
possible to build a machine that
2:04:00
could answer any mathematical
2:04:03
question? several centuries
2:04:03
later, David Hilbert together
2:04:08
with Wilhelm Ackerman, redefined
2:04:08
blindnesses question. At a
2:04:12
conference in Berlin in 1928,
2:04:12
they defined the chairman's
2:04:16
problem or decision problem. The
2:04:16
decision problem asks, Is it
2:04:21
possible to build a machine that
2:04:21
can decide whether or not any
2:04:24
mathematical question can be
2:04:24
proved in some mathematical
2:04:27
system? girdle showed that not
2:04:27
every true statement was
2:04:32
provable. But was there a way to
2:04:32
decide whether or not a
2:04:35
statement was provable? It was
2:04:35
an important question. Such a
2:04:40
method would be most useful to
2:04:40
mathematicians. It would tell
2:04:45
them when they ought to give up
2:04:45
and thereby save them from
2:04:48
wasting their lives searching
2:04:48
for proofs that don't exist.
2:04:52
Alonzo church got the first
2:04:52
results on the on shadings
2:04:55
problem. He defined a
2:04:55
programming language and proved
2:04:59
so Questions about it are
2:05:00
undecidable quote, it follows
2:05:05
that the unshaded problem is
2:05:05
unsolvable in the case of any
2:05:08
system of Symbolic Logic which
2:05:08
is consistent in the sense of
2:05:12
girdle, Alonzo church in an
2:05:12
unsolvable problem of elementary
2:05:17
number theory 1935.
2:05:21
The next year churches' student
2:05:21
Alan Turing published another
2:05:25
example of an undecidable
2:05:25
problem, the halting problem,
2:05:29
quote, girdle has shown that
2:05:29
there are propositions you such
2:05:34
that neither you nor not you is
2:05:34
provable. On the other hand, I
2:05:39
shall show that there is no
2:05:39
general method which tells
2:05:42
whether a given formula U is
2:05:42
provable. Alan cheering it on
2:05:47
computable numbers with an
2:05:47
application to the unshaded
2:05:50
problem 1936.
2:05:54
It was in this paper that Turing
2:05:54
introduced the concept of a
2:05:57
general purpose programmable
2:05:57
computer birthing the digital
2:06:00
age. Hilbert never got the
2:06:00
answers he hoped for. We can't
2:06:06
prove the consistency of our
2:06:06
mathematical foundation. We
2:06:10
can't prove everything that is
2:06:10
true and given undecidability we
2:06:14
can't even be sure whether a
2:06:14
statement has approved for not.
2:06:18
And yet, despite not getting the
2:06:18
answers he hoped for. Hilbert
2:06:22
knew the right questions to ask
2:06:22
the answers produced great
2:06:26
discoveries. Quote, I'd like to
2:06:26
make the outrageous claim that
2:06:32
has a little bit of truth. That
2:06:32
actually all of this that's
2:06:36
happening now with the computer
2:06:36
taking over the world, the
2:06:39
digitalization of our society of
2:06:39
information in human society.
2:06:45
You could say in a way is the
2:06:45
result of a philosophical
2:06:48
question that was raised by
2:06:48
David Hilbert at the beginning
2:06:51
of the century. Gregory chayton.

1902. deceptively simple Daya. fantine
2:07:46
equations were often notoriously
2:07:50
difficult. A famous example is
2:07:50
the dire fontein equation, a to
2:07:56
the power of n equals b to the
2:07:56
power of n plus c to the power
2:08:00
of n. This equation is easy when
2:08:00
n equals one, or when n equals
2:08:06
two millennia ago, Pythagoras
2:08:06
proved there were infinite
2:08:10
solutions when n equals two. And
2:08:10
yet, no one had found even one
2:08:15
solution for n greater than or
2:08:15
equal to three. No one knew of a
2:08:20
cube number A to the power of
2:08:20
three. That was the sum of two
2:08:24
other cube numbers in 1673.
2:08:24
Pierre de firma wrote in his
2:08:29
notes that he had a proof that
2:08:29
there were no solutions when n
2:08:32
greater than or equal to three,
2:08:32
but no one had ever found it.
2:08:37
Nor was anyone able to
2:08:37
rediscover a proof. The missing
2:08:41
proof became known as firmers
2:08:41
Last Theorem. The problem went
2:08:46
unsolved for 321 years, until in
2:08:46
1994, after seven years of work,
2:08:54
Andrew Wiles completed a 129
2:08:54
page proof that no whole number
2:08:58
solutions exist when n is
2:08:58
greater than or equal to three.
2:09:03
If mathematicians had a
2:09:03
procedure to solve diaphram tiny
2:09:06
equations, Andrew Wiles wouldn't
2:09:06
have had to spend seven years
2:09:10
working on this problem.
2:09:10
Instead, he could program a
2:09:13
computer to follow the procedure
2:09:13
and the computer would crank out
2:09:17
a solution. In 1970, Hilbert
2:09:17
10th problem was solved. solving
2:09:24
it required 21 years of work by
2:09:24
four mathematicians Martin
2:09:28
Davis, Julia Robinson, Hilary
2:09:28
Putnam, and Yuri mais j civic.
2:09:34
They're proof called the mrtp
2:09:34
theorem, after their initials
2:09:38
gave a negative result, they
2:09:38
proved there is no general
2:09:42
procedure for solving diffontein
2:09:42
equations. And they proved it in
2:09:46
a shocking way. They showed an
2:09:46
equivalence between solutions to
2:09:51
Daya fantine equations and what
2:09:51
is computable In other words,
2:09:55
for any imaginable computer
2:09:55
program, there is a dire fantana
2:09:59
question. Whose solutions equal all the
2:10:00
outputs of that computer
2:10:03
program? This was so surprising
2:10:03
that many mathematicians had
2:10:08
difficulty believing it. It
2:10:08
meant there is a dire fantine
2:10:12
equation that picks chess moves
2:10:12
like deep blue, and there's a
2:10:15
dire fantine equation does your
2:10:15
taxes like TurboTax, and there's
2:10:19
yet another die of fantine
2:10:19
equation that does spell
2:10:22
checking like Microsoft Word.
2:10:22
For anything a computer can
2:10:26
compute. There's a dire fontein
2:10:26
equation that gives the exact
2:10:30
same answers. But despite how
2:10:30
surprising their result was, it
2:10:34
was true. And this is why there
2:10:34
can be no general method for
2:10:39
solving dire fontein equations,
2:10:39
because the question of whether
2:10:42
or not a program finishes
2:10:42
Turing's halting problem is
2:10:46
equivalent to asking whether or
2:10:46
not some diffontein equation has
2:10:49
solutions. Since the halting
2:10:49
problem is not generally
2:10:53
solvable, the equivalence
2:10:53
between diffontein equations and
2:10:57
computers mentai fantine
2:10:57
equations weren't generally
2:11:00
solvable either. Yet again, what
2:11:00
Hilbert asked for couldn't be
2:11:05
provided Hilbert questions
2:11:05
probed at the heart of
2:11:09
consistency provability,
2:11:09
decidability and computability.
2:11:14
They didn't leave where he
2:11:14
expected, but they did reveal
2:11:17
deep truths about the nature of
2:11:17
mathematics, universal
2:11:22
equations. In 1978, the
2:11:22
mathematician James P. Jones
2:11:27
went a step further, just as it
2:11:27
is possible to make a computer
2:11:31
program that runs all other
2:11:31
computer programs. It is also
2:11:35
possible to make a Daya fantine
2:11:35
equation that includes all other
2:11:39
Daya fantine equations. Quote,
2:11:39
makes j civics theorem implies
2:11:45
also the existence of particular
2:11:45
undecidable di fantine
2:11:48
equations. In fact, there must
2:11:48
exist universal diaphragm tiny
2:11:53
equations, polynomial analogues
2:11:53
of the universal Turing machine,
2:11:58
and quote, James P. Jones and
2:11:58
undecidable diophantine
2:12:03
equations 1980.
2:12:06
Such diffontein equations are
2:12:06
general purpose computers plug
2:12:10
in the programmer has one of the
2:12:10
variables to the equation, and
2:12:13
the solutions to the equation
2:12:13
will be the outputs of that
2:12:16
program. Jones provided an
2:12:16
example of such an equation. It
2:12:22
is complex, but the truths
2:12:22
concerning this single equation
2:12:25
include all truths concerning
2:12:25
the executions and outputs of
2:12:29
all computer programs. Quote, as
2:12:29
V varies through the positive
2:12:36
integers, the equation defines
2:12:36
every recursively enumerable
2:12:40
set. This is to our mind the
2:12:40
attraction of the universal
2:12:45
equations at once. This equation
2:12:45
defines primes, Fibonacci
2:12:50
numbers, Lucas numbers, perfect
2:12:50
numbers, theorems of Zed F, or
2:12:55
indeed theorems of any other x
2:12:55
amortizable theory. James P.
2:13:00
Jones in three universal
2:13:00
representations of recursively
2:13:03
enumerable sets 1978.
2:13:07
We might consider such universal
2:13:07
equations as got equations,
2:13:11
equations whose solutions
2:13:11
contain and include all the
2:13:14
others. In his 1987 book
2:13:14
algorithmic information theory,
2:13:19
Gregory chayton describes one
2:13:19
such equation, the exponential
2:13:23
Daya fantine equation computer.
2:13:23
It has 20,000 variables and is
2:13:28
200 pages long. This equation
2:13:28
perfectly replicates the
2:13:33
behavior of the Lisp programming
2:13:33
language, he describes the
2:13:38
equation as follows. Quote, if
2:13:38
the Lisp expression k has no
2:13:43
value, then this equation will
2:13:43
have no solution. If the Lisp
2:13:48
expression k has a value, then
2:13:48
this equation will have exactly
2:13:52
one solution. In this unique
2:13:52
solution, n equals the value of
2:13:57
the expression K. And quote,
2:13:57
Gregory chayton in metamath, the
2:14:04
quest for omega 2004
2:14:08
chattin showed that even modern
2:14:08
day computers and programming
2:14:12
languages have counterparts in
2:14:12
the form of Daya fantine
2:14:15
equations. Universal Daya
2:14:15
fantine equations are
2:14:19
remarkable. They exist in pure
2:14:19
arithmetic. The arithmetical
2:14:24
relations they encode represent
2:14:24
every program that can be
2:14:28
computed along with all of their
2:14:28
outputs. Among these solutions,
2:14:32
we can find the valid proofs of
2:14:32
every theorem in every
2:14:35
mathematical system, every way
2:14:35
of playing every computer game
2:14:39
that has all will ever be
2:14:39
invented, and simulations of
2:14:42
every galaxy in the observable
2:14:42
universe down to the atomic
2:14:45
level. Universal die fantine
2:14:45
equations contain in their
2:14:50
solutions everything computable
2:14:50
since known physical laws are
2:14:54
computable quantum detailed
2:14:54
histories of every particle
2:14:57
interaction in the observable
2:14:57
universe
2:15:00
counted among these solutions.
2:15:00
Jones's discovery of universal
2:15:04
Daya fantine equations inspired
2:15:04
him to quote chapter 11, verse
2:15:09
seven of the Bhagavad Gita,
2:15:09
whatever you wish can be seen
2:15:12
all at once right here. This
2:15:12
universal form can show you all
2:15:16
that you now desire. Everything
2:15:16
is here completely. Given that
2:15:21
such equations include
2:15:21
everything computable, including
2:15:25
all physical laws and systems as
2:15:25
well as simulations of any
2:15:28
observers, mind and brain. Could
2:15:28
these equations be the glue
2:15:31
connecting eternal mathematical
2:15:31
truth with contingent physical
2:15:35
truths? The Universal Deaf
2:15:35
Taylor in 1991, Bruno Marshall
2:15:42
wrote a program he called the
2:15:42
universal Deaf tailor, a program
2:15:46
that generates and runs all
2:15:46
programs. In order to run every
2:15:50
program without getting stuck on
2:15:50
a program that never ends. The
2:15:54
Universal dovetail into leaves,
2:15:54
or dovetails on the processing,
2:15:59
doing a little bit of work on
2:15:59
each program at a time. The
2:16:03
program is simple. The full
2:16:03
program is quite short,
2:16:07
consisting of about 300 lines of
2:16:07
Lisp code. It's pseudocode is
2:16:13
even simpler for K from zero to
2:16:13
infinity, for j from zero to k,
2:16:21
for I from zero to J, compute k
2:16:21
steps of program I on input J.
2:16:28
This program sequentially
2:16:28
generates every program and runs
2:16:32
it for every input. The longer
2:16:32
the universal dovetail runs, the
2:16:37
more programs it generates, and
2:16:37
the more steps of each program
2:16:40
it performs. If allowed to run
2:16:40
forever, it runs every program
2:16:45
there is the universal Duff
2:16:45
Taylor, like a fractal is itself
2:16:50
simple and yet it generates
2:16:50
infinite complexity. In the
2:16:55
words of plotinus for that which
2:16:55
generates is always simpler than
2:16:59
that which is generated to 70
2:16:59
ad. This program like universal
2:17:06
diaphragm tiny equations
2:17:06
contains all. While studying the
2:17:10
consequences of the existence of
2:17:10
all computations, Marshall made
2:17:15
an incredible discovery what he
2:17:15
describes as the many histories
2:17:18
interpretation of elementary
2:17:18
arithmetic. The discovery served
2:17:23
as the basis of his 1998 PhD
2:17:23
thesis computability physics and
2:17:28
cognition. This paper explains
2:17:28
how we can explain the
2:17:32
appearance of a multiverse given
2:17:32
two assumptions. One, all
2:17:38
computations exist and two,
2:17:38
computation supports cognition.
2:17:45
Quote, we will explain that once
2:17:45
we adopt the computation list
2:17:49
hypothesis, which is a form of
2:17:49
mechanistic assumption, we have
2:17:53
to derive from it how our belief
2:17:53
in the physical laws can emerge
2:17:56
from only arithmetic and
2:17:56
classical computer science.
2:18:00
Bruno Mars shall in the
2:18:00
computation list reformulation
2:18:04
of the mind body problem 2013
2:18:08
given there exists universal
2:18:08
Daya fantine equations, all
2:18:12
computations exist as a
2:18:12
consequence of arithmetical
2:18:15
truth concerning them. While
2:18:15
there is no physical realization
2:18:19
of the perpetual execution of
2:18:19
the universal Duff Taylor, it's
2:18:22
complete execution exists in
2:18:22
number theory as a consequence
2:18:26
of arithmetical truth. There are
2:18:26
for instance, diaphragm tiny
2:18:31
equations whose solutions
2:18:31
exactly equal all the
2:18:34
sequentially generated states
2:18:34
reached by the universal Duff
2:18:37
Taylor. So if we accept the self
2:18:37
existence truth of two plus two
2:18:42
equals four, we must also accept
2:18:42
truths concerning universal Daya
2:18:46
fantine equations, truths that
2:18:46
concern all computational
2:18:50
histories and all simulated
2:18:50
realities. Quote, to be sure,
2:18:56
the existence of the UD is a
2:18:56
logical consequence of
2:18:59
elementary arithmetic with
2:18:59
Church's thesis or Turing's
2:19:02
thesis and quote, Bruno ma shall
2:19:02
in discussion list 2019.
2:19:11
It therefore becomes a purely
2:19:11
mathematical question to prove
2:19:14
whether some diaphragm tiny
2:19:14
equation contains in its
2:19:17
solutions a computational state
2:19:17
equivalent to some person's
2:19:20
physical brain state. We would
2:19:20
then exist for the same reason
2:19:25
that two plus two equals four as
2:19:25
an inevitable consequence of
2:19:29
mathematical truth. The question
2:19:29
Why is there anything at all is
2:19:34
reduced to why does two plus two
2:19:34
equals four, a story of creation
2:19:41
We have arrived at a plausible
2:19:41
story of creation. We can now
2:19:46
connect the causeless abstract
2:19:46
entities, logic, truth and
2:19:50
numbers with a viable cause for
2:19:50
our perceptions of a physical
2:19:54
reality. Why does anything exist
2:19:54
because necessity requires
2:20:00
As logical laws, logical laws
2:20:00
imply incontrovertibly truth
2:20:06
such truth includes mathematical
2:20:06
truth. Mathematical truth
2:20:11
defines numbers, numbers possess
2:20:11
number relations, number
2:20:17
relations imply equations.
2:20:17
equations define computable
2:20:22
relations computable relations
2:20:22
define all computations, all
2:20:29
computations including
2:20:29
algorithmically generated
2:20:32
observers. And these observers
2:20:32
experience apparent physical
2:20:37
realities ancient anticipations
2:20:37
this account of how eternal
2:20:43
mathematical truths could give
2:20:43
rise to contingent physical
2:20:46
truths depended on recent
2:20:46
discoveries. If required a deep
2:20:50
understanding of modern ideas,
2:20:50
universal equations, computers,
2:20:55
computation, virtual reality and
2:20:55
simulation only a century ago,
2:21:01
we didn't even have words for
2:21:01
these concepts. Despite this, a
2:21:06
few ancient thinkers gave
2:21:06
theories for existence that are
2:21:09
eerily similar to this modern
2:21:09
creation story. They postulated
2:21:14
something primal and simple that
2:21:14
gave rise to the numbers and
2:21:17
from numbers arose beings
2:21:17
consciousness and matter. 2600
2:21:23
years ago, Lowry jr wrote that
2:21:23
numbers proceed from the tower
2:21:27
and that from numbers that all
2:21:27
things are born, quote, The Tao
2:21:33

2:21:33
birth to two, two gives birth to
2:21:39

2:22:49
theory concerning the relations

between various levels of being
2:22:54

2:22:54

2:22:57
of emanations the first
2:22:57
emanation his new divine mind,
2:23:01

2:23:01
New proceeds the world soul,
2:23:07
from the world soul proceeds
2:23:07
individual human souls, and
2:23:11
finally, matter, at the lowest
2:23:11
level of being and thus the
2:23:15
least perfected level of the
2:23:15
cosmos. Quote, the one is not a
2:23:21
being but the generator of
2:23:21
being, the greatest later than
2:23:25
the one must be the intellectual
2:23:25
principle and it must be the
2:23:29
second of all existence, for
2:23:29
what emanates from the
2:23:33
intellectual principle is a
2:23:33
reason principle or logos. And
2:23:38
as soon as there is
2:23:38
differentiation, number exists.
2:23:42
Thus number the primal and true
2:23:42
is principle and source of
2:23:46
actuality to the beings. The
2:23:46
souls substantial existence
2:23:51
comes from the intellectual
2:23:51
principle, the soul itself a
2:23:56
divine thought, and possessing
2:23:56
the divine thoughts, or ideas,
2:24:00
of all things, contains all
2:24:00
things consented within it. This
2:24:05
gives the degree in which the
2:24:05
cosmos is then sold not by a
2:24:08
soul belonging to it, but by one
2:24:08
present to it, it is mastered,
2:24:12
not Master, not possessive, but
2:24:12
possessed. This one universe is
2:24:17
all bound together in shared
2:24:17
experience. So matter is

of mathematical procedure in

dealing with its subjects as

extended, and it's setting up of

different prior principles for

different objects. These gift a

propolis in a commentary on the
2:25:35
first book of Euclid elements
2:25:35
circa 450 ad,
2:25:40
the causeless cause found? Could
2:25:40
this be the answer? Could things
2:25:46
be so simple, in order for this
2:25:46
explanation of existence, to be
2:25:50
correct, mathematical truth must
2:25:50
be causeless mathematical
2:25:55
existence must depend on neither
2:25:55
human minds nor on physical or
2:25:59
material things. In addition,
2:25:59
mathematical truth must be
2:26:04
something capable of generating
2:26:04
observers, observers who
2:26:08
consciously perceive their
2:26:08
environment, and which they
2:26:10
consider as existing physically.
2:26:10
Ideally, this causeless cause
2:26:15
will illuminate the relation
2:26:15
between the mental and material
2:26:19
and explain why the universe
2:26:19
obeys simple laws. Can the
2:26:23
theory achieve this? Is it
2:26:23
causeless for mathematical truth
2:26:29
to serve as a causeless? Cause
2:26:29
it must exist cause lessly math
2:26:34
must depend on neither minds no
2:26:34
matter independent of minds. Do
2:26:41
numbers and their properties
2:26:41
exist beyond the minds of
2:26:44
mathematicians and their
2:26:44
scribblings on blackboards? Had
2:26:48
Hilbert program succeeded and
2:26:48
given a mathematical theory
2:26:51
capable of proving all true
2:26:51
statements, then arguably,
2:26:55
mathematics might only be that
2:26:55
which follows from this theory.
2:26:59
Math would then be an invention
2:26:59
of the human mind. But the
2:27:04
failure of Hilbert program and
2:27:04
girdles proof of the
2:27:07
impossibility for any finite
2:27:07
theory to define all
2:27:10
mathematical truth meant that
2:27:10
mathematical truth is infinite
2:27:13
and beyond description, and
2:27:13
therefore cannot be a product of
2:27:16
human minds. Quote, the
2:27:16
existence of absolutely
2:27:22
undecidable mathematical
2:27:22
propositions seems to disprove
2:27:26
the view that mathematics is
2:27:26
only our own creation, for the
2:27:30
creator necessarily knows all
2:27:30
properties of his creatures
2:27:34
because they can't have any
2:27:34
others except those he has given
2:27:37
to them. So this alternative
2:27:37
seems to imply that mathematical
2:27:41
objects and facts or at least
2:27:41
something in them, exist
2:27:45
objectively and independently of
2:27:45
our mental acts and decisions.
2:27:49
That is to say, it seems to
2:27:49
imply some form or other of
2:27:54
platonism, or realism as to the
2:27:54
mathematical objects. That

2:28:08
c is math invented or
2:28:08
discovered, independent of
2:28:13
matter. The infinite nature of
2:28:13
mathematical truth also implies
2:28:18
an independence from matter are

observable universe has an
2:28:22
information capacity of 10 to
2:28:22
the power of 120 bits. This

number is large, but finite.
2:28:27
Nowhere in physics is there room
2:28:33
to store represent or hold the
2:28:33
infinite true statements of
2:28:37
mathematics. If there are
2:28:37
infinite primes, infinite
2:28:41
factors of zero, infinite digits
2:28:41
of pi, they don't exist
2:28:45
physically. If these infinite
2:28:45
properties don't and can't
2:28:49
depend on physical processes
2:28:49
operating within a material
2:28:52
universe, it follows that
2:28:52
mathematical properties must
2:28:55
exist independently of matter.
2:28:55
Quote, it is our firm belief
2:29:01
that the Pythagorean Theorem
2:29:01
needs not be created, nor the
2:29:04
fact that the circumference of a
2:29:04
circle is 3.14 and so on, times
2:29:09
the diameter. The laws of nature
2:29:09
and the collection of truths,
2:29:14
values and their interrelations
2:29:14
are primordial and have always
2:29:18
existed. CW varieties in four

2:29:26
to work, abstract objects,
2:29:32
truth, numbers, equations, and
2:29:32
so on must play a causal role in
2:29:37
generating reality and
2:29:37
perceptions. The default
2:29:41
position of philosophers has
2:29:41
been that abstract objects have
2:29:44
no effects they cause and do
2:29:44
nothing. But we must admit that
2:29:48
this has always been an
2:29:48
assumption it's never been
2:29:51
proven. Quote, although
2:29:51
philosophers deny that abstract
2:29:57
objects can have causal effects
2:29:57
on concrete objects.

abstract objects are often

2:30:19
recently, recent advances in
2:30:19
mathematics give us pause. The
2:30:23
discovery that all computations
2:30:23
exist as a consequence of
2:30:26
mathematical truth makes us
2:30:26
wonder whether abstract
2:30:30
mathematics is really so in
2:30:30
effectual, but can mind or
2:30:34
matter really be created by
2:30:34
math? The cause of minds?
2:30:40
consciousness remains one of
2:30:40
humanity's last great mysteries.
2:30:44
While science has not settled
2:30:44
the question of what
2:30:47
consciousness is, it has
2:30:47
progressed by developing a
2:30:49
testable theory of
2:30:49
consciousness. In the 1600s
2:30:54
thinkers such as Rene Descartes
2:30:54
and Thomas Hobbes advanced the
2:30:57
idea of mechanism, the theory
2:30:57
that our brains and bodies are
2:31:01
machines that operate according
2:31:01
to mechanical rules. In 1936,
2:31:06
the discovery of universal
2:31:06
machines or computers led to the
2:31:10
church cheering thesis, which
2:31:10
says the behavior of any finite
2:31:14
machine can be perfectly
2:31:14
replicated by an appropriately
2:31:17
programmed computer. This is
2:31:17
their special power. It is what
2:31:22
makes computers so useful.
2:31:22
Without changing your computer's
2:31:27
hardware, it is able to run any
2:31:27
one of the millions of
2:31:30
applications available to it,
2:31:30
including applications not yet
2:31:33
developed or conceived off. Each
2:31:33
new application provides the
2:31:38
computer with new functionality
2:31:38
and behaviors. Some were quick
2:31:42
to recognize the implications of
2:31:42
the church cheering thesis for
2:31:46
theories of minds, brains and
2:31:46
consciousness. The two fathers
2:31:51
of computing, Alan Turing and
2:31:51
john von Neumann noticed
2:31:55
parallels between computers and
2:31:55
the mind. In 1948, Turing wrote
2:32:00
the first chess playing program
2:32:00
with an in his 1950 paper
2:32:04
Computing Machinery and
2:32:04
intelligence cheering asked Can
2:32:08
machines think the last work of
2:32:08
john von Neumann was a lecture
2:32:12
series, the computer and the
2:32:12
brain, published posthumously in
2:32:16
1958. In it one normal explains
2:32:16
that it is not that the brain
2:32:21
acts like a computer, but that
2:32:21
computers are so varied in what
2:32:25
they can do that they can be set
2:32:25
up to imitate any machine,
2:32:28
presumably even the human brain.
2:32:28
Quote. The important result of
2:32:34
Turing's is that in this way,
2:32:34
the first universal machine can
2:32:38
be caused to imitate the
2:32:38
behavior of any other machine,
2:32:42

2:32:42
and the brain 1958.
2:32:48
In the 1960s, and 1970s,
2:32:48
philosophers of mind, including
2:32:53
Hilary Putnam, and his student
2:32:53
Jerry Fodor developed what they
2:32:56
call functionalism. In its
2:32:56
digital form, functionalism is
2:33:01
known as the computational
2:33:01
theory of mind or computational
2:33:05
ism. This is the idea that
2:33:05
function or computation is the
2:33:09
foundation of consciousness. The
2:33:09
computational theory of mind
2:33:14
remains as the most popular
2:33:14
theory for consciousness among
2:33:17
scientists and philosophers,
2:33:17
quote, computational ism or
2:33:23
digital mechanism or simply
2:33:23
mechanism is a hypothesis in the
2:33:27
cognitive science according to
2:33:27
which we can be emulated by a
2:33:30
computer without changing our
2:33:30
private subjective feeling.

2:33:34
computational history

2:33:42
If the computational theory of
2:33:42
mind is true, then mathematics
2:33:46
can explain where observers come

2:33:50
among the infinite computational
2:33:50
histories within arithmetical
2:33:54
truth. See, what is
2:33:54
consciousness? And can a machine
2:33:59
Be conscious recent discoveries
2:33:59
in physics lend support to
2:34:04
computational ism. In 1981,
2:34:04
Jacob Beck and Stein discovered
2:34:10
a physical limit now known as
2:34:10
the back end Stein bound. This
2:34:14
bound says that a physical
2:34:14
system of finite mass and volume
2:34:18
can contain at most a finite
2:34:18
amount of information. This
2:34:23
applies to any finite physical
2:34:23
system or brain, the earth, the
2:34:27
solar system, our galaxy, or the
2:34:27
observable universe. Given that
2:34:33
the observable universe has a
2:34:33
finite mass and volume, it
2:34:36
follows by the back and Stein
2:34:36
bound that it has a finite
2:34:39
description. Given that it is a
2:34:39
finite description. It follows
2:34:44
by the church Turing thesis that
2:34:44
the evolution of the observable
2:34:47
universe is something that is
2:34:47
perfectly replicated by a
2:34:50
certain computer program. This
2:34:50
program contains a version of
2:34:55
You, me, the earth and everyone
2:34:55
and everything present in our
2:34:59
universe. Our shared histories and
2:35:00
memories would be identical. But
2:35:04
the question remains are these
2:35:04
computational doppelgangers
2:35:08
conscious like we are, if we
2:35:08
inspected the contents of this
2:35:12
computer program, we would find
2:35:12
analogs of all the objects of
2:35:16
our own universe, we will find
2:35:16
the same books, articles, and
2:35:21
movies. Among these, we will
2:35:21
even find many works on the
2:35:25
mysterious nature of
2:35:25
consciousness. These same books
2:35:29
will also appear in a purely
2:35:29
computational version of our
2:35:32
universe written by
2:35:32
computational authors, who
2:35:35
apparently are just as baffled
2:35:35
by their conscious experiences
2:35:39
as we are, if these purely
2:35:39
computational versions of us are
2:35:43
not conscious, what drives them
2:35:43
to write and read books about
2:35:46
consciousness. If on the other
2:35:46
hand, they are just as conscious
2:35:51
as we are, then the idea of a
2:35:51
separately existing physical
2:35:55
reality becomes redundant. In
2:35:55
that case, for all we know, we
2:36:00
are these computational
2:36:00
versions, we would then exist as
2:36:04
pure computations, we would
2:36:04
inhabit the computational
2:36:08
histories of simulated realities
2:36:08
that exist only as a consequence
2:36:12
of mathematical truth concerning
2:36:12
universal equations. every
2:36:17
imaginable computation is
2:36:17
realized in arithmetic has true
2:36:20
relations about these universal
2:36:20
equations. This includes the
2:36:25
computations that describe you,
2:36:25
your environment, and even the
2:36:29
evolving state of your brain as
2:36:29
it processes this very sentence.
2:36:33
If computational ism is right,
2:36:33
this is who we are, quote, will
2:36:39
explore the fascinating
2:36:39
relations between computation,
2:36:42
mathematics, physics and mind
2:36:42
and explore a crazy sounding
2:36:47
belief of mine that our physical
2:36:47
world not only is described by
2:36:50
mathematics, but that it is
2:36:50
mathematics, making yourself
2:36:54
aware parts of a giant
2:36:54
mathematical object. Max Tegmark
2:36:58
in our mathematical universe
2:36:58
2014
2:37:03
the cause of matter can
2:37:03
mathematical truth with its
2:37:07
inherent infinite collection of
2:37:07
computational histories,
2:37:10
explained matter, physical laws
2:37:10
and universes. How can abstract
2:37:16
things like truth numbers,
2:37:16
computations give rise to
2:37:20
concrete things like chairs,
2:37:20
bricks, and houses? What's the
2:37:25
difference between abstract
2:37:25
existence versus concrete
2:37:29
existence? Some say the
2:37:29
difference is only a matter of
2:37:33
perspective. To a being who
2:37:33
inhabits an abstract object, be
2:37:37
it an abstract mathematical
2:37:37
object or abstractly existing
2:37:41
computation, it seems concrete
2:37:41
to them. Quote, this equivalence
2:37:47
between physical and
2:37:47
mathematical existence means
2:37:50
that if a mathematical structure
2:37:50
contains a self aware sub
2:37:53
structure, it will perceive
2:37:53
itself as existing in a
2:37:55
physically real world just as we
2:37:55
do. And quote, Max Tegmark in
2:38:02
the mathematical universe 2007
2:38:06
the relative aspect of concrete
2:38:06
existence is explicit in Marcus
2:38:11
molars definition of physical
2:38:11
existence. Quote, given two
2:38:16
objects A and B, we say that
2:38:16
they physically exist for each
2:38:20
other if and only if, under
2:38:20
certain auxiliary conditions,
2:38:23
modifying the state of a will
2:38:23
affect the state of B and vice
2:38:27
versa. Marcus Miller in could
2:38:27
the physical world be emergent
2:38:32
instead of fundamental, and why
2:38:32
should we ask 2017.
2:38:38
Whenever conscious observer
2:38:38
experiences or interacts with
2:38:41
another object, that object
2:38:41
appears concrete to that
2:38:45
observer, even if, from another
2:38:45
point of view, both that
2:38:48
observer and objects seem
2:38:48
abstract of the modes of
2:38:53
existence, this understanding
2:38:53
implies mind over matter. Math
2:38:58
produces an infinity of
2:38:58
conscious minds. And the
2:39:00
perceptions of these minds
2:39:00
include experiences of material
2:39:04
realities. Computational ism,
2:39:04
together with the mathematical
2:39:08
existence of all computations,
2:39:08
leads to a causal reversal
2:39:12
between Mind and Matter. Quote,
2:39:12
what results is not a primitive
2:39:18
matter with consciousness
2:39:18
emerging from its organization,
2:39:21
but the reverse consciousness is
2:39:21
now the more primitive and
2:39:25
matter more rather, the
2:39:25
appearance of material
2:39:28
organization emerges from all
2:39:28
the possible experiences of all
2:39:32
the possible consciousnesses end
2:39:32
quote. Bruno ma shall in the
2:39:38
amoebas secret 2014
2:39:42
matter is then as plotinus
2:39:42
supposed a Phantasm is this
2:39:47
testable? This is a big pill to
2:39:47
swallow, are we to take as
2:39:52
serious the idea that we live
2:39:52
inside an equation and this
2:39:56
equation somehow produces all
2:39:56
computations by
2:40:00
That you have it solutions, and
2:40:00
that the whole physical universe
2:40:04
is just some kind of shared
2:40:04
hallucination. extraordinary
2:40:08
claims require extraordinary
2:40:08
evidence. Unless there is a way
2:40:13
to test or neither confirm or
2:40:13
falsify this theory, we are not
2:40:17
operating in the realm of
2:40:17
science, but fantasy.
2:40:21
Fortunately, there is a way to
2:40:21
test this theory. Due to the
2:40:26
fact that not all programs
2:40:26
appear with equal frequency, a
2:40:30
particular bias should appear in
2:40:30
the resulting computational
2:40:33
histories. We can then check for
2:40:33
this bias by comparing our
2:40:38
observations of the character of
2:40:38
physical law and the properties
2:40:41
of our universe against the
2:40:41
predictions made by the theory.
2:40:45
Not all predictions of a theory
2:40:45
are necessarily testable. But
2:40:49
the more predictions of a theory
2:40:49
we test and confirm, the more
2:40:52
our confidence in that theory
2:40:52
grows. If our observations match
2:40:57
the predictions, we gain
2:40:57
evidence in support of the
2:41:00
theory. If they don't match, we
2:41:00
rule the theory out. This is how
2:41:06
all theories are tested.
2:41:06
algorithmic information theory,
2:41:11
the reason not all programs
2:41:11
occur with equal frequency is
2:41:15
due to a consequence of
2:41:15
algorithmic information theory
2:41:18
or a IIT. This field was
2:41:18
developed by Ray Solomonoff,
2:41:23
Andrei Kolmogorov, and Gregory
2:41:23
chayton. Starting in the 1960s.
2:41:29
chayton says a IIT is the result
2:41:29
of putting Shannon's information
2:41:33
theory and Turing's
2:41:33
computability theory into a
2:41:36
cocktail shaker and shaking
2:41:36
vigorously. The basic idea is to
2:41:41
measure the complexity of an
2:41:41
object by the size in bits of
2:41:44
the smallest program for
2:41:44
computing it. Across the
2:41:47
infinite programs executed by
2:41:47
Universal equations, some
2:41:51
programs exhibit identical
2:41:51
behavior. This is because the
2:41:55
program's code may instruct it
2:41:55
to read only a fraction of its
2:41:59
total available code. Consider
2:41:59
all possible bit strings
2:42:03
representing programs executed
2:42:03
by Universal equations. programs
2:42:09
that complete are naturally self
2:42:09
delimiting. They define their
2:42:13
own length by virtue of reading
2:42:13
only a finite number of bits.
2:42:18
When the bits that are red are
2:42:18
the same, the program behavior
2:42:21
is the same even when the rest
2:42:21
of the unread part of the bits
2:42:25
strings differ. If, for example,
2:42:25
a program length is nine bits,
2:42:30
we can calculate that this
2:42:30
program should appear once every
2:42:33
two to the power of nine or 512
2:42:33
bit strings. Self delimited 10
2:42:40
bit programs would be half as
2:42:40
common, appearing once every two
2:42:43
to the power of 10, or 1024.
2:42:43
programs. Conversely, eight PID
2:42:50
programs are twice as common as
2:42:50
nine bit ones. We can use this
2:42:55
consequence of algorithmic
2:42:55
information theory to make
2:42:58
several predictions about the
2:42:58
character of physical law.
2:43:02
Quote, the main point is that
2:43:02
the derivation is constructive
2:43:07
and it provides the technical
2:43:07
means to derive physics from
2:43:10
arithmetic. And this will make
2:43:10
the computation list hypothesis
2:43:15
empirically testable and thus
2:43:15
scientific in the property
2:43:18
analysis of science. Bruno Mars

2:43:28
confirming evidence could such a
2:43:28
bowl theory be true? For now,
2:43:35
let's neither accepted nor
2:43:35
reject this theory to do either
2:43:39
before weighing the evidence
2:43:39
would be premature. So let us
2:43:43
not believe anything and
2:43:43
maintain an open mind. For the
2:43:48
time we will only play with the
2:43:48
idea and see where it leads. As
2:43:53
with any theory, the only path
2:43:53
forward is to see what this
2:43:56
theory predicts and then to
2:43:56
compare the predictions with our
2:43:59
observations. If we find it
2:43:59
leads in a fruitful direction by
2:44:04
making predictions we can
2:44:04
confirm and by not making
2:44:07
predictions we can refute then
2:44:07
we will have cause to
2:44:10
tentatively accept this theory.
2:44:10

2:44:18
generated by the infinite
2:44:18
computations inherent to
2:44:21
causeless arithmetical truth for
2:44:21
that matter? What are the
2:44:26
predictions? at first blush, it
2:44:26
seems impossible to get any
2:44:31
useful predictions from a theory
2:44:31
that includes all computations
2:44:34
and all observations for if they
2:44:34
all exist, any observation is
2:44:40
compatible with the theory as
2:44:40
Victor Stanger noted theories
2:44:44
that explain everything
2:44:44
explained nothing. Fortunately,
2:44:49
there is a catch, not all
2:44:49
observations are equally likely.
2:44:53
If our conscious states result
2:44:53
from the existence of all
2:44:56
computations, then they are
2:44:56
subject to the rules of our
2:45:00
algorithmic information theory.
2:45:00
This enables us to make testable
2:45:04
predictions and thereby tied
2:45:04
back to hard science,
2:45:07
observation and measurement.
2:45:07
Some of the predictions of this
2:45:12
theory provide clues to
2:45:12
otherwise unsolvable questions
2:45:15
in physics and cosmology money.
2:45:15
These predictions offer answers
2:45:19
to such fundamental mysteries as
2:45:23
why the universe obeys simple
2:45:23
mathematical, life friendly
2:45:28
laws. Why empiricism by experimental
2:45:30
reproducibility works.
2:45:36
Why auctions razor works?
2:45:39
Why the laws appear fine tuned
2:45:39
for life.
2:45:44
Why the laws are quantum
2:45:44
mechanical?
2:45:47
Why uncertainty and randomness
2:45:47
exist in physics?
2:45:52
Why infinite descriptions are
2:45:52
needed to explain any
2:45:55
occurrence? Why observation and information
2:45:58
are fundamental in physics and
2:46:03
why the universe has time and
2:46:03
the beginning. For example, The
2:46:07
Big Bang these results are the
2:46:07
work of pioneers in the theory,
2:46:12
who include Bruno Mars shell,
2:46:12
Max Tegmark, Russell Standish,
2:46:16
and Marcus Moeller. using the
2:46:16
tools of computer science, math,
2:46:21
information theory and
2:46:21
algorithmic information theory,
2:46:25
they revealed how these traits
2:46:25
of the universe result from our
2:46:28
mind states being
2:46:28
computationally generated,
2:46:32
quote, the appearance of a
2:46:32
universe or even universes must
2:46:37
be explained by the geometry of
2:46:37
possible computations. Bruno ma

2:46:47
Let's review the evidence for
2:46:47
this most speculative of
2:46:50
theories, which is presently at
2:46:50
the forefront of mathematics and
2:46:53
physics. Why laws? We take for
2:46:53
granted that our universe obeys
2:46:59
laws. But why should it? What's
2:46:59
the source of these laws? Why
2:47:06
are they so simple? Why aren't
2:47:06
they ever violated? Why these
2:47:11
laws and not others? All these
2:47:11
questions are mysteries left
2:47:15
unaddressed by science. Quote,
2:47:15
in the Orthodox view, the laws
2:47:22
of physics are floating in an
2:47:22
explanatory void. Ironically,
2:47:26
the essence of the scientific
2:47:26
method is rationality and logic.
2:47:30
We suppose that things are the
2:47:30
way they are for a reason. Yet
2:47:34
when it comes to the laws of
2:47:34
physics themselves, well, we are
2:47:38
asked to accept that they exist
2:47:38
reason lessly and quote, Paul
2:47:44
Davis in the Flexi laws of
2:47:44
physics 2007.
2:47:49
Quote, with the equations when
2:47:49
they are not too complicated, we
2:47:55
can predict phenomena. But in
2:47:55
truth, the equation doesn't
2:47:59
explain anything. it compresses,
2:47:59
certainly, in a very ingenious
2:48:04
way, the description of the
2:48:04
physical world, but it does not
2:48:08
explain the nature of bodies nor
2:48:08
why these bodies have a laws nor
2:48:13
from where these laws come. And,
2:48:13
quote, Bruno ma shall in the
2:48:18
amoebas, secret 2014
2:48:22
that laws are never violated on
2:48:22
its face seems highly
2:48:26
improbable. For in the space of
2:48:26
possibility for each way there
2:48:31
is for the universe to obey the
2:48:31
laws, there are infinite ways it
2:48:35
might deviate from them. Quote,
2:48:35
for each law govern world there
2:48:40
are countless variants that
2:48:40
would fail in different ways to
2:48:43
be wholly law governed. Derek
2:48:43
parfit in why anything? Why this
2:48:50
2008
2:48:54
why the laws hold is unknown to
2:48:54
science. And yet this feature of
2:48:59
reality is the very basis that
2:48:59
allows us to do science. A
2:49:04
lawful universe is the basis of
2:49:04
empiricism. It is why we can
2:49:09
repeat experiments and make
2:49:09
predictions about the future
2:49:12
based on past observations. But
2:49:12
why does this work and why
2:49:17
should it work? Marshall
2:49:17
explains the emergence of laws
2:49:21
as a consequence of the
2:49:21
computational reality. He says
2:49:25
the laws are the consistent
2:49:25
extensions of programs that
2:49:28
produce the observers mind
2:49:28
state, quote, arithmetic
2:49:34
contains or executes all
2:49:34
computations. Your first person
2:49:39
is distributed on all
2:49:39
computations going through your
2:49:42
current first person state. To
2:49:42
make any prediction on the
2:49:46
future of your possible inputs,
2:49:46
you need to take all the
2:49:49
computations into account and
2:49:49
the laws of physics is what is
2:49:52
invariant in all consistent
2:49:52
extensions. Bruno ma shall in
2:49:57
discussion list 2019
2:50:01
Muller goes further and gives a
2:50:01
mathematical proof that shows
2:50:05
why given algorithmic
2:50:05
information theory, observers
2:50:08
will with high probability,
2:50:08
observer persistence of
2:50:12
regularities, ie laws, quote,
2:50:12
that is computable regularities
2:50:19
that were holding in the past
2:50:19
tend to persist in the future.
2:50:23
Intuitively, highly compressible
2:50:23
histories are those that contain
2:50:27
regularities, which can be used
2:50:27
to generate shorter
2:50:30
descriptions. Market smaller in
2:50:30
law without law, from observer
2:50:35
states to physics via
2:50:35
algorithmic information theory
2:50:39
2020. Because most programs are
2:50:41
simple, and simple programs tend
2:50:45
to keep doing what they have
2:50:45
been doing. This gives the
2:50:47
appearance of a fixed set of
2:50:47
laws that holds into the future
2:50:51
as the program unfolds. So in a
2:50:51
sense, the laws of physics are
2:50:56
the rules of the programs that
2:50:56
instantiate us, as seen by those
2:51:00
of us inside those programs. Why
2:51:00
the laws are mathematical. It
2:51:06
has long been recognized that
2:51:06
mathematics is unreasonably
2:51:09
effective in describing the
2:51:09
physical laws. In 1623, Galileo
2:51:15
wrote the universe is written in
2:51:15
the language of mathematics.
2:51:20
This connection between math and
2:51:20
physics so puzzles scientists,
2:51:26
quote, The miracle of the
2:51:26
appropriateness of the language
2:51:29
of mathematics for the
2:51:29
formulation of the laws of
2:51:32
physics is a wonderful gift
2:51:32
which we neither understand nor
2:51:36
deserve. We should be grateful
2:51:36
for it and hope that it will
2:51:40
remain valid in future research
2:51:40
and that it will extend for
2:51:43
better or for worse to our
2:51:43
pleasure, even though perhaps
2:51:48
also to our bafflement to wide
2:51:48
branches of learning. And quote,
2:51:55
Eugene Wigner in the
2:51:55
unreasonable effectiveness of
2:51:58
mathematics in the natural
2:51:58
sciences 1960
2:52:03
mathematical patterns appear
2:52:03
everywhere in nature. But why
2:52:07
should physics be so
2:52:07
mathematical? Tegmark offers a
2:52:11
simple explanation because
2:52:11
physical theories result from
2:52:15
our perceptions of what are
2:52:15
ultimately mathematical
2:52:17
structures. Quote, the various
2:52:17
approximations that constitute
2:52:23
our current physics theories are
2:52:23
successful because simple
2:52:27
mathematical structures can
2:52:27
provide good approximations of
2:52:30
how a self aware sub structure
2:52:30
will perceive more complex
2:52:34
mathematical structures. In
2:52:34
other words, our successful
2:52:38
theories are not mathematics
2:52:38
approximating physics, but
2:52:42
mathematics approximating
2:52:42
mathematics. And quote, Max
2:52:47
Tegmark in his the theory of
2:52:47
everything really the ultimate
2:52:50
ensemble theory 1998
2:52:55
why the laws are simple. In the
2:52:55
second century, Ptolemy wrote,
2:53:00
we consider it a good principle
2:53:00
to explain the phenomena by the
2:53:03
simplest hypothesis possible.
2:53:03
This rule of thumb is called the
2:53:08
law of parsimony or Occam's
2:53:08
razor. It is the idea that in
2:53:13
science, the simplest answer
2:53:13
that fits the facts is usually
2:53:16
right. Occam's razor is no doubt
2:53:16
a useful and effective rule. But
2:53:21
until recently, no one
2:53:21
understood why it works. What is
2:53:25
striking about the great
2:53:25
questions of physics is their
2:53:28
simplicity. Deep truths of
2:53:28
nature can be expressed by short
2:53:33
formulas, like F equals MA and
2:53:33
the equals mc squared. Physical
2:53:39
equations rarely involve more
2:53:39
than a few terms, rather than
2:53:43
dozens or hundreds. physicists
2:53:43
are all struck by this
2:53:47
simplicity. Einstein remarked,
2:53:47
the eternal mystery of the world
2:53:52
is its comprehensibility. Given,
2:53:52
there are far more ways for
2:53:56
these formulas to be more
2:53:56
complex. It's especially odd
2:54:00
that they should be so simple
2:54:00
quote. Compared with simple
2:54:05
laws, there is a far greater
2:54:05
range of complicated laws. We
2:54:10
will have some reason to believe
2:54:10
that there are at least two
2:54:13
partial selectors being law
2:54:13
governed and having simple laws.
2:54:18
Derek parfit in why anything?
2:54:18
Why this 2008.
2:54:26
Quote, but the lesson is that,
2:54:26
at present, the idea that the
2:54:30
ultimate laws are as simple as
2:54:30
possible is a hope not something
2:54:34
suggested by the evidence.
2:54:34
Moreover, the prospect still
2:54:39
faces the challenge of
2:54:39
explanatory regression, as one
2:54:42
would be left to explain why the
2:54:42
underlying laws should be so
2:54:45
simple. Sean Carroll in Why is
2:54:45
there something rather than
2:54:50
nothing? 2018
2:54:54
the mystery of simple
2:54:54
comprehensible laws can now be
2:54:58
answered. We have Found the selector that
2:55:00
preferentially selects universes
2:55:03
with simple laws. algorithmic
2:55:03
information theory tells us that
2:55:07
for each bit saved in a
2:55:07
program's description, its
2:55:10
occurrences double. This adds up
2:55:10
fast, a program that's 30 bits
2:55:16
shorter, say 120 bits versus 150
2:55:16
bits occurs two to the power of
2:55:22
30, or over 1 billion times more
2:55:22
often. Ray Solomonoff, the
2:55:28
father of algorithmic
2:55:28
information theory was the first
2:55:31
to draw a connection between AI
2:55:31
tea and Occam's razor quotes. On
2:55:38
a direct intuitive level, the
2:55:38
higher priority probability
2:55:42
assigned to a sequence with a
2:55:42
short description corresponds to
2:55:45
one possible interpretation of
2:55:45
Occam's razor. And quote, Ray
2:55:51
Solomonoff in a formal theory of
2:55:51
inductive inference 1964
2:55:57
when Muller applied algorithmic
2:55:57
information theory to observer
2:56:00
states, he found that it led to
2:56:00
the prediction of simple
2:56:03
physical laws, quote, observers
2:56:03
Well, with high probability, see
2:56:10
an external world that is
2:56:10
governed by simple computable
2:56:14
probabilistic laws. And quote,
2:56:14
Marcus Miller in law without
2:56:20
law, from observer states to
2:56:20
physics via algorithmic
2:56:23
information theory 2020
2:56:27
why the laws are life friendly.
2:56:27
One of the most surprising
2:56:31
discoveries in physics of the
2:56:31
past 50 years was the discovery
2:56:35
that the laws of physics and
2:56:35
constants of nature appear
2:56:38
specially selected to allow
2:56:38
complexity in life to arise. We
2:56:43
wrote, a life giving factor lies
2:56:43
at the center of the whole
2:56:46
machinery and design of the
2:56:46
world. That the constants of
2:56:50
nature, the strengths of the
2:56:50
forces, the particle masses,
2:56:54
etc, are just right to permit
2:56:54
complex structures to arise is
2:56:58
mysterious. Why are the laws
2:56:58
this way? Why are they life
2:57:03
friendly? physicists ask, why
2:57:03
does the universe appear fine
2:57:08
tuned. Quote, as we look out
2:57:08
into the universe and identify
2:57:14
the many accidents of physics
2:57:14
and astronomy that have worked
2:57:17
together to our benefit, it
2:57:17
almost seems as if the universe
2:57:20
must in some sense have known we
2:57:20
were coming. Freeman Dyson in
2:57:25
energy in the universe 1971.
2:57:30
Quote, the fine tunings, how
2:57:30
fine tuned are they? Most of
2:57:36
them are 1% sort of things. In
2:57:36
other words, if things are 1%,
2:57:41
different, everything gets bad.
2:57:41
And the physicist could say
2:57:46
maybe those are just luck. On
2:57:46
the other hand, this
2:57:50
cosmological constant is tuned
2:57:50
to one part in 10 to the power
2:57:54
of 120 120 decimal places.
2:57:54
Nobody thinks that's accidental.
2:58:02
That is not a reasonable idea
2:58:02
that something is tunes to 120
2:58:07
decimal places just by accident.
2:58:07
That's the most extreme example
2:58:12
of fine tuning. And quote,
2:58:12
Leonard Susskind in what we
2:58:17
still don't know, are we real
2:58:17
2004.
2:58:23
The first step in explaining
2:58:23
fine tuning is to recognize that
2:58:27
for any universe, to be
2:58:27
perceived, requires that it be
2:58:30
populated with conscious
2:58:30
observers. This reasoning is
2:58:33
known as the anthropic
2:58:33
principle. The next step is to
2:58:38
explain why any universe exists
2:58:38
that supports conscious
2:58:41
observers. Typical answers are
2:58:41
that the universe was either
2:58:45
designed or it is just one among
2:58:45
a vast set of mostly dead
2:58:49
universes. Quote, we imagined
2:58:49
our universe to be unique, but
2:58:55
it is one of an immense number,
2:58:55
perhaps an infinite number of
2:58:58
equally valid, equally
2:58:58
independent, equally isolated
2:59:02
universes. There will be life in
2:59:02
some and not in others. Carl
2:59:08
Sagan in pale blue dot 1994
2:59:13
the existence of infinite
2:59:13
computational histories
2:59:16
guarantees that some will be of
2:59:16
a type that can support life.
2:59:21
Moreover, algorithmic
2:59:21
information theory tells us the
2:59:24
resulting physics should be
2:59:24
maximally simple while
2:59:27
respecting the constraint of
2:59:27
being life friendly. Quote, in
2:59:32
this paper, I show why, in an
2:59:32
ensemble theory of the universe,
2:59:36
we should be inhabiting one of
2:59:36
the elements of that ensemble
2:59:39
with least information content
2:59:39
that satisfies the anthropic
2:59:43
principle. This explains the
2:59:43
effectiveness of aesthetic
2:59:46
principles such as outcomes
2:59:46
raiza in predicting usefulness
2:59:50
of scientific theories, and
2:59:50
quote, Russell Standish in why
2:59:56
Occam's razor 2004
3:00:00
And indeed, this is what we find
3:00:00
when we examine our physics.
3:00:05
Quote, a very interesting
3:00:05
question to me is, is the
3:00:09
universe more complicated than
3:00:09
it needs to be to have us here?
3:00:14
In other words, is there
3:00:14
anything in the universe which
3:00:17
is just here to amuse
3:00:17
physicists? It's happened again
3:00:22
and again that there was
3:00:22
something which seemed like it
3:00:24
was just a frivolity like that.
3:00:24
Were later we've realized that,
3:00:28
in fact, no, if it weren't for
3:00:28
that little thing, we wouldn't
3:00:32
be here. I'm not convinced,
3:00:32
actually, that we have anything
3:00:36
in this universe, which is
3:00:36
completely unnecessary to life.
3:00:41
Max Tegmark in what we still
3:00:41
don't know, why are we here?
3:00:45
2004. See, is the universe fine tuned?
3:00:48
Why quantum mechanics quantum
3:00:55
mechanics is a cornerstone
3:00:55
theory of modern physics. It's
3:00:59
among the most thoroughly tested
3:00:59
of all theories in science, and
3:01:03
it's given us the most accurate
3:01:03
predictions in all of physics.
3:01:07
But quantum mechanics is
3:01:07
incredibly strange. It suggests
3:01:12
the existence of many infinite
3:01:12
histories, ie many worlds or
3:01:16
many minds, observation or
3:01:16
measurement appears to cause the
3:01:21
infinite set of possibilities to
3:01:21
collapse to just one of the
3:01:24
possibilities and the selected
3:01:24
result is absolutely
3:01:27
unpredictable. According to
3:01:27
quantum mechanics, no one can
3:01:32
predict whether a photon will be
3:01:32
reflected by or transmitted
3:01:35
through a piece of glass, not
3:01:35
even in principle. It's
3:01:38
fundamentally random. Quantum
3:01:38
Mechanics includes apparent
3:01:43
absurdities, like unobserved
3:01:43
cats being simultaneously alive
3:01:47
and dead, non local faster than
3:01:47
light influences and unlimited
3:01:51
computation underlying physical
3:01:51
reality. Quote, I have never
3:01:57
been able to let go of questions
3:01:57
like How come existence? How
3:02:02
come the quantum and quote john
3:02:02
Archibald Wheeler in John's
3:02:08
black holes and quantum foam
3:02:08
1998
3:02:13
of the mysteries in physics, how
3:02:13
come the quantum ranks highly?
3:02:18
Niels Bohr said those who are
3:02:18
not shocked when they first come
3:02:22
across quantum theory cannot
3:02:22
possibly have understood it.
3:02:26
When a Heisenberg admits, I
3:02:26
repeated to myself again and
3:02:30
again the question Can nature
3:02:30
possibly be so absurd as it
3:02:33
seemed to us in these atomic
3:02:33
experiments, and Richard Fineman
3:02:38
said, I think I can safely say
3:02:38
that nobody understands quantum
3:02:42
mechanics will have thought if
3:02:42
an ultimate theory could explain
3:02:46
quantum mechanics, it would be a
3:02:46
sure sign the theory was on the
3:02:50
right track. Quote, the most
3:02:50
important test is whether it
3:02:55
gives anything like quantum
3:02:55
mechanics. If it does, we have a
3:03:00
go ahead sign? If not, we have
3:03:00
to revise our thinking. And
3:03:05
quote, john Archibald Wheeler
3:03:05
quoted in trespassing on
3:03:09
Einsteins lawn 2014
3:03:13
Marshalls 1998 thesis
3:03:13
computability physics and
3:03:18
cognition gave the first hints
3:03:18
that features of quantum
3:03:21
mechanics such as indeterminism
3:03:21
the many parallel histories, the
3:03:26
non cleanability of matter, and
3:03:26
quantum logic could be explained
3:03:30
as a consequence of
3:03:30
computational ism. Quote, as in
3:03:35
quantum mechanics, computational
3:03:35
ism highlights a strong
3:03:38
indeterminism as well as a form
3:03:38
of nonlocality. Computational
3:03:43
ism entails the existence of a
3:03:43
phenomenology of many worlds or
3:03:47
parallel states. End quote.

3:03:59
Marshall writes, the quantum
3:03:59
empirical clues happen to be
3:04:02
serious hints that the physical
3:04:02
emerges from an internally
3:04:05
defined statistics on the
3:04:05
numbers, dreams or computations
3:04:09
seen from inside. Standish went
3:04:09
further, in a 2004 paper and in
3:04:15
his 2006 book, he showed one
3:04:15
could derive the basic rules or
3:04:20
postulates of quantum mechanics,
3:04:20
including the Schrodinger
3:04:24
equation purely from basic
3:04:24
assumptions about observation
3:04:28
within an infinite set of
3:04:28
possibilities. Quote, the
3:04:33
explanation of quantum mechanics
3:04:33
as describing the process of
3:04:36
observation within a plenitude
3:04:36
of possibilities is for me the
3:04:39
pinnacle of achievement of the
3:04:39
paradigm discussed in this book,
3:04:43
I can now say that I understand
3:04:43
quantum mechanics. So when I say
3:04:49
I understand quantum mechanics,
3:04:49
I mean that I know that the
3:04:52
first three postulates are
3:04:52
directly consequences of as
3:04:55
being observers. Quantum
3:04:55
mechanics is simply a theory of
3:05:00
observation and quote, Russell
3:05:00
Standish in theory of nothing
3:05:05
2006 irreducible randomness one of
3:05:08
the strangest features of
3:05:13
quantum mechanics is the
3:05:13
presence of irreducible
3:05:16
randomness that creates absolute
3:05:16
unpredictability. Compounding
3:05:21
this strangeness is the fact
3:05:21
that the equations of quantum
3:05:24
mechanics are entirely
3:05:24
deterministic. And yet, when a
3:05:28
measurement is made, it seems
3:05:28
the universe momentarily stops
3:05:32
following these equations to
3:05:32
randomly select one possibility
3:05:35
to make real from among the many
3:05:35
possibilities present in the
3:05:39
equations. This was a pill too
3:05:39
hard for Einstein to swallow. He
3:05:45
declared, God doesn't play dice
3:05:45
with the world. And in the end,
3:05:49
he never accepted it. The single
3:05:49
electron double slit experiment
3:05:54
was voted the most beautiful
3:05:54
experiment in physics. In this
3:05:59
experiment, an electron is put
3:05:59
into a superposition where the
3:06:03
electron exists in multiple
3:06:03
locations at once, then its
3:06:07
location is measured. But when
3:06:07
we measure the electrons
3:06:10
location, it will appear in only
3:06:10
one location seemingly at
3:06:15
random. Before measurement, it's
3:06:15
impossible, even in theory to
3:06:20
predict where the electron will
3:06:20
be. If we inhabit a
3:06:24
computational reality, why do we
3:06:24
see any randomness or
3:06:27
unpredictability computations
3:06:27
are perfectly predictable? Mike,
3:06:32
this observation of randomness
3:06:32
give us cause to doubt or rule
3:06:36
out our being in a computational
3:06:36
reality. The opposite is true.
3:06:41
The existence of an infinite
3:06:41
computational reality explains
3:06:45
why we encounter absolute
3:06:45
unpredictability. If only one
3:06:50
computational history existed,
3:06:50
observing randomness would be
3:06:53
caused to dismiss the theory.
3:06:53
But here there are infinite
3:06:57
computational histories. Some of
3:06:57
these histories will be similar
3:07:02
to each other some so similar as
3:07:02
to be almost indistinguishable.
3:07:07
Since there are infinite
3:07:07
computational histories each
3:07:10
observers mind state can be
3:07:10
found within infinite parallel
3:07:14
computational histories. In a
3:07:14
1988 conference, and in a 1991
3:07:19
paper mechanism and personal
3:07:19
identity Marshall explains how
3:07:23
the appearance of randomness
3:07:23
emerges from multiple
3:07:26
instantiations of a single
3:07:26
observers mind. He calls the
3:07:31
phenomenon first person
3:07:31
indeterminacy. Quote, to predict
3:07:37
the first person observable
3:07:37
outcome of any physical
3:07:39
experiment, you have to assume
3:07:39
that your current computational
3:07:43
state will not be obtained in
3:07:43
some other part of the universe
3:07:46
or the multiverse with different
3:07:46
output for your experience.
3:07:51
Bruno ma shall in the
3:07:51
computation list reformulation
3:07:54
of the mind body problem 2013.
3:07:58
In summary, no brain that
3:07:58
belongs to multiple distinct
3:08:02
universes where computational
3:08:02
histories can ever be sure what
3:08:06
it will see next. Multiple
3:08:06
parallel histories contain
3:08:10
identical instances of the same
3:08:10
observers mind, state or brain.
3:08:15
Fundamental unpredictability and
3:08:15
randomness will result from the
3:08:19
observers inability to determine
3:08:19
which universe she's a part of,
3:08:23
as she exists in all of them.
3:08:23
Quote, it is impossible for any
3:08:28
observer to deduce with
3:08:28
certainty on the basis of her
3:08:31
observations and memory which
3:08:31
world she is a part of. That is,
3:08:36
there are always many different
3:08:36
worlds for which being contained
3:08:39
in them is compatible with
3:08:39
everything she knows, but which
3:08:42
imply different predictions for
3:08:42
future observations. Marcus
3:08:47
Miller in could the physical
3:08:47
world be emergent instead of
3:08:50
fundamental, and why should we
3:08:50
ask 2017.
3:08:56
So even in a fully deterministic
3:08:56
reality, the existence of
3:09:00
infinite histories makes the
3:09:00
appearance of randomness
3:09:03
inevitable. The physicist
3:09:03
shining a photon at a piece of
3:09:06
glasses in an infinity of
3:09:06
histories where the photon will
3:09:09
reflect and is in an infinity of
3:09:09
histories where the photon will
3:09:13
pass through. The physicist
3:09:13
can't tell which until after the
3:09:17
experiment is performed, and she
3:09:17
learns the result. Ultimately,
3:09:22
randomness stems from our
3:09:22
inability to self locate within
3:09:25
the infinite sea of
3:09:25
indistinguishable computational
3:09:28
histories. Tegmark notes how
3:09:28
randomness appears in
3:09:32
deterministic processes. Quote,
3:09:32
it gradually hits me that this
3:09:39
illusion of randomness business
3:09:39
really wasn't specific to
3:09:42
quantum mechanics at all.
3:09:42
Suppose that some future
3:09:46
technology allows you to be
3:09:46
cloned while you're sleeping,
3:09:49
and that your two copies are
3:09:49
placed in rooms numbered zero
3:09:52
and one. When they wake up,
3:09:52
they'll both feel that the room
3:09:56
number they read is completely
3:09:56
unpredictable and random.
3:10:01
End quote. Max Tegmark in our
3:10:01
mathematical universe 2014.
3:10:08
Einstein is vindicated. God
3:10:08
doesn't play dice with the
3:10:12
world. But perhaps not even God
3:10:12
can predict what universe you
3:10:17
will find yourself in once you
3:10:17
perform a measurement that
3:10:20
splits yourself. See, does
3:10:20
everything that can happen
3:10:25
actually happen? infinite
3:10:25
complexity. In 1948 Richard
3:10:31
Fineman developed the path
3:10:31
integral formulation, which
3:10:34
provided a new way to understand
3:10:34
quantum mechanics. Fineman
3:10:39
showed that you get the same
3:10:39
results quantum mechanics
3:10:42
predicts by taking into account
3:10:42
and adding up every one of the
3:10:45
infinite combinations of
3:10:45
possible particle paths and
3:10:48
interactions. It was bizarre,
3:10:48
but it worked. And this new
3:10:54
formulation provided key
3:10:54
insights that helped develop
3:10:57
quantum electrodynamics or QE D.
3:10:57
in 1965. Fineman together with
3:11:04
ceniceros tomonaga and Julian
3:11:04
shringar shared the 1965 Nobel
3:11:08
Prize in Physics for developing
3:11:08
QED. But while adding up all of
3:11:13
these infinite possibilities
3:11:13
gave the right answers presented
3:11:16
a great puzzle which bothered
3:11:16
Fineman. Quote, it always
3:11:22
bothers me that according to the
3:11:22
laws as we understand them
3:11:25
today, it takes a computing
3:11:25
machine an infinite number of
3:11:28
logical operations to figure out
3:11:28
what goes on in no matter how
3:11:32
tiny a region of space and no
3:11:32
matter how tiny a region of
3:11:35
time, how can all that be going
3:11:35
on in that tiny space? Why
3:11:41
should it take an infinite
3:11:41
amount of logic to figure out
3:11:43
what one tiny piece of space
3:11:43
slash time is going to do?

Richard Fineman in the character
3:11:48
of physical law 1965.
3:11:54
Under quantum mechanics, an
3:11:54
infinite number of things happen
3:11:58
behind the scenes, the smaller
3:11:58
the scales, you look, the more
3:12:03
seems to be happening with no
3:12:03
bottom in sight. The appearance
3:12:07
of infinite happenings, infinite
3:12:07
computations and infinite
3:12:11
logical operations underlying
3:12:11
physical reality is mysterious.
3:12:16
perhaps the simplest answer for
3:12:16
why reality appears this way is
3:12:20
it appears this way because that
3:12:20
is the way reality is infinite
3:12:25
computational histories form the
3:12:25
foundation of reality, then
3:12:29
infinities in physics might just
3:12:29
be a reflection of this reality.
3:12:33
Quote. In short, within each
3:12:33
universe, all observable
3:12:37
quantities are discrete, but the
3:12:37
multiverse as a whole is a
3:12:41
continuum. When the equations of
3:12:41
quantum theory describe a
3:12:45
continuous, but not directly
3:12:45
observable transition between
3:12:48
two values of a discrete
3:12:48
quantity, what they are telling
3:12:51
us is that the transition does
3:12:51
not take place entirely within
3:12:54
one universe. So perhaps the
3:12:54
price of continuous motion is
3:12:59
not an infinity of consecutive
3:12:59
actions, but an infinity of
3:13:03
concurrent actions taking place
3:13:03
across the multiverse. And
3:13:07
quote, David Deutsch in the
3:13:07
discrete and the continuous
3:13:11
2001. Quote, matter is only what seems
3:13:14
to emerge at infinity from a
3:13:19
first person plural point of
3:13:19
view, defined by sharing the
3:13:22
computations which are
3:13:22
infinitely multiplied in the
3:13:25
universal Duff Taylor's work
3:13:25
when persons look at themselves
3:13:28
and their environment below
3:13:28
their substitution level. The
3:13:32
non cloning results from the
3:13:32
fact that such a matter emerges
3:13:36
only from an infinity of
3:13:36
distinct computations. And
3:13:40
quote, Bruno ma shall in the
3:13:40

3:13:45
of the mind body problem 2013
3:13:49
quantum computers, Richard
3:13:49
Fineman and David Deutsch are
3:13:54
the two fathers of the quantum
3:13:54
computer. Fineman proposed their
3:13:58
possibility in 1982, and in
3:13:58
1985, Deutsch described how to
3:14:03
build one. These computers
3:14:03
exploit the unlimited complexity
3:14:08
inherent in quantum mechanics to
3:14:08
build computers of incredible
3:14:12
power. How quantum computers do
3:14:12
what they do is puzzling. Each
3:14:17
qubit added to a quantum
3:14:17
computer doubles its power. a
3:14:22
quantum computer with 300 cubits
3:14:22
can simultaneously process two
3:14:26
to the power of 300 states. This
3:14:26
number of states exceeds the two
3:14:32
to the power of 265 atoms in the
3:14:32
observable universe. How could a
3:14:38
tabletop device process more
3:14:38
states than there are atoms? How
3:14:43
could it solve problems that no
3:14:43
conventional computer could
3:14:46
solve in the lifetime of the
3:14:46
universe even if all matter and
3:14:49
energy in the observable
3:14:49
universe were recruited for that
3:14:53
purpose? Some found the
3:14:53
abilities of these computers so
3:14:57
incredible, they concluded
3:14:57
quantum computers
3:15:00
simply weren't possible. After
3:15:00
all, where exactly would all
3:15:04
that computation be occurring?
3:15:04
Deutschen Tegmark offers some
3:15:08
answers. Quote, since the
3:15:08
universe as we see it lacks the
3:15:14
computational resources to do
3:15:14
the calculations. Where are they
3:15:17
being done, it can only be in
3:15:17
other universes. quantum
3:15:23
computers share information with
3:15:23
huge numbers of versions of
3:15:26
themselves throughout the
3:15:26
multiverse. David Deutsch and

3:15:35
Given engineering challenges for
3:15:35
decades, quantum computers
3:15:38
remained only theoretical.
3:15:38
Today, quantum computers are a
3:15:43
reality. In 2019, engineers at
3:15:43
Google reported that their 53
3:15:49
qubit quantum computer solved in
3:15:49
200 seconds a problem that would
3:15:53
take the world's most powerful
3:15:53
supercomputer 10,000 years.
3:15:58
Today, anyone can sign up for
3:15:58
free to program and use IBM's
3:16:02
quantum computers over the
3:16:02
internet. What makes quantum
3:16:06
computers difficult to build is
3:16:06
that to work, they must be
3:16:10
completely isolated from the
3:16:10
environment such that they are
3:16:13
not measured by anyone or
3:16:13
anything until it finishes its
3:16:16
work. by isolating the quantum
3:16:16
computer from the environment,
3:16:21
observers temporarily make their
3:16:21
existence compatible with all
3:16:25
the possible states the quantum
3:16:25
computer might simultaneously be
3:16:28
in. Parallel computations
3:16:28
performed by quantum computers
3:16:33
can then be explained by the
3:16:33
work of parallel computational
3:16:36
histories. Quote, if current
3:16:36
efforts to build quantum
3:16:41
computers succeed, they will
3:16:41
provide further evidence for the
3:16:45
quantum multiverse as they
3:16:45
would, in essence, be exploiting
3:16:49
the parallelism of the quantum
3:16:49
multiverse for parallel
3:16:52
computation. And quote, Max
3:16:52
Tegmark in parallel universes
3:16:58
2003 See, how do quantum computers
3:17:01
work? Why time, the universe,
3:17:08
our lives, and even our thoughts
3:17:08
are inextricably linked with the
3:17:12
march of time. Few things are as
3:17:12
familiar to us as time and yet
3:17:17
time remains little understood.
3:17:17
See what is time 2500 years ago,
3:17:25
Heraclitus recognized change to
3:17:25
be the only constant in life,
3:17:29
saying all entities move and
3:17:29
nothing remains still. But it
3:17:34
doesn't seem logically necessary
3:17:34
for a universe to have time.
3:17:38
Quote, mathematical structures
3:17:38
are eternal and unchanging. They
3:17:43
don't exist in space and time.
3:17:43
Rather, space and time exist in
3:17:48
some of them. If Cosmic History
3:17:48
were a movie, then the
3:17:53
mathematical structure would be
3:17:53
the entire DVD. Max Tegmark in
3:17:58
our mathematical universe 2014
3:18:02
Why should our universe have a
3:18:02
property like time, all
3:18:06
computers process information in
3:18:06
an ordered sequence of steps.
3:18:11
This ordering defines a notion
3:18:11
of time that exists for any
3:18:15
computation. Quote, a Turing
3:18:15
machine requires time to
3:18:20
separate the sequence of states
3:18:20
it occupies as it performs the
3:18:24
computation. And quote, Russell
3:18:24
Standish in why Occam's razor
3:18:30
2004 Muller further showed that with
3:18:33
algorithmic information theory,
3:18:36
we can predict the appearance of
3:18:36
a universe that evolves in time.
3:18:41
Quote, our theory predicts that
3:18:41
observers should indeed expect
3:18:45
to see two facts which are
3:18:45
features of our physics as we
3:18:48
know it. First, the fact that
3:18:48
the observer seems to be part of
3:18:53
an external world that evolves
3:18:53
in time, a universe. And second,
3:18:59
that this external world seems
3:18:59
to have had an absolute
3:19:02
beginning in the past the Big
3:19:02
Bang, Marcus Miller in could the
3:19:07
physical world be emergent
3:19:07
instead of fundamental, and why
3:19:10
should we ask 2017?
3:19:15
Assuming we are part of an
3:19:15
unfolding computation, then we
3:19:18
should expect to find ourselves
3:19:18
in a universe with time,
3:19:22
beginning in time, current
3:19:22
evidence suggests our universe
3:19:27
has a beginning. But why should
3:19:27
it until the middle of the 20th
3:19:32
century, most scientists believe
3:19:32
the universe was infinitely old
3:19:37
without a beginning. They
3:19:37
considered theories of an abrupt
3:19:40
creation event to be inelegant.
3:19:40
Accordingly, scientists resisted
3:19:46
the idea of a beginning until
3:19:46
overwhelming evidence came out
3:19:49
in its favor. It wasn't until we
3:19:49
could actually see the afterglow
3:19:53
of the Big Bang in the form of
3:19:53
microwaves that scientists were
3:19:57
convinced the universe began a
3:19:57
finite
3:20:00
time ago. We call this point the
3:20:00
beginning because in tracing the
3:20:04
history of the universe
3:20:04
backwards, we hit a point where
3:20:07
predicting earliest states
3:20:07
breaks down and further
3:20:10
backwards tracing becomes
3:20:10
impossible. The physics either
3:20:13
stops providing sensible
3:20:13
answers, or we run into an
3:20:17
explosion of possibilities and
3:20:17
can't tell which of them is
3:20:20
real. The theory of cosmic
3:20:20
inflation gives an account of
3:20:24
what caused the hot, dense early
3:20:24
phase of the universe. See what
3:20:30
caused the Big Bang. But
3:20:30
inflation makes further
3:20:34
backwards prediction or retro
3:20:34
diction impossible. it wipes its
3:20:39
footprints with a set of
3:20:39
infinite pre history's quotes.
3:20:44
Since our own pocket universe
3:20:44
would be equally likely to lie
3:20:47
anywhere on the infinite tree of
3:20:47
universes produced by eternal
3:20:50
inflation, we would expect to
3:20:50
find ourselves arbitrarily far
3:20:54
from the beginning. The Infinite
3:20:54
inflating network would
3:20:58
presumably approach some kind of
3:20:58
a steady state, losing all
3:21:01
memory of how it started. So the
3:21:01
statistical predictions for our
3:21:06
universe would be determined by
3:21:06
the properties of this steady
3:21:09
state configuration, independent
3:21:09
of hypotheses about the ultimate
3:21:13
beginning. End quote. Alan Guth
3:21:13
in eternal inflation
3:21:18
implications 2013.
3:21:22
Muller shows that algorithmic
3:21:22
information theory predicts most
3:21:26
observers will find themselves
3:21:26
in a universe with simple
3:21:29
initial conditions and an
3:21:29
absolute beginning in time. He
3:21:33
explains this reasoning for a
3:21:33
hypothetical observer named
3:21:37
Abby, quote, If she continues
3:21:37
computing backwards to retract
3:21:42
earlier and earlier states of
3:21:42
her universe, she will typically
3:21:46
find simpler and more compact
3:21:46
states with measures of entropy
3:21:49
or algorithmic complexity
3:21:49
decreasing simply because she is
3:21:53
looking at earlier and earliest
3:21:53
stages of an unfolding
3:21:56
computation. At some point, Abby
3:21:56
will necessarily arrive at the
3:22:01
state that corresponds to the
3:22:01
initial state of the graph
3:22:04
machines computation, where
3:22:04
simplicity and compactness are
3:22:07
maximal. At this point, two
3:22:07
cases are possible. Either
3:22:12
Abby's method of computing
3:22:12
backwards will cease to work, or
3:22:15
Avi will retronix a fictitious
3:22:15
sequence of states before the
3:22:19
initial state, typically with
3:22:19
increasing complexity backwards
3:22:22
in time. And quote, Marcus
3:22:22
Miller in law without law, from
3:22:28
observer states to physics via
3:22:28
algorithmic information theory
3:22:32
2018. This mirrors what cosmic
3:22:34
inflation does for our universe.
3:22:39
In an alternate history where
3:22:39
humans developed algorithmic
3:22:42
information theory before
3:22:42
microwave telescopes, we might
3:22:46
have predicted the beginning of
3:22:46
the universe before telescopic
3:22:49
evidence came in information as
3:22:49
fundamental. physicists are
3:22:54
increasingly recognizing that
3:22:54
information plays a fundamental
3:22:58
role in physics. Scientists have
3:22:58
long understood that matter and
3:23:03
energy can be neither created
3:23:03
nor destroyed. They are in all
3:23:08
interactions conserved, but only
3:23:08
recently of physicists realize
3:23:14
the same is true for
3:23:14
information. Physical
3:23:17
information can neither be
3:23:17
copied nor deleted. There is an
3:23:21
equivalent law for the
3:23:21
conservation of information.
3:23:25
This discoveries stem from the
3:23:25
black hole information paradox.
3:23:30
According to general relativity,
3:23:30
dropping something into a black
3:23:33
hole destroys its information,
3:23:33
like an ultimate furnace. But
3:23:38
according to quantum mechanics,
3:23:38
information can't be destroyed.
3:23:43
At best, a black hole can only
3:23:43
rearrange information like an
3:23:47
ultimate Shredder. In 1981. This
3:23:47
paradox sparked the black hole
3:23:53
war waged by two camps of
3:23:53
physicists. After decades of
3:23:57
debates, the black hole was
3:23:57
settled in favor of quantum
3:24:01
mechanics. Information can't be
3:24:01
destroyed, not even by a black
3:24:06
hole. Physicists now understand
3:24:06
the kind of mass energy
3:24:10
information equivalence There is
3:24:10
also an equivalence between
3:24:15
entropy in thermodynamics and
3:24:15
entropy in information theory.
3:24:19
And constants of nature are
3:24:19
closely linked to the ultimate
3:24:23
physical limits of computational
3:24:23
speed, efficiency and storage
3:24:27
density. See, How good can
3:24:27
technology get? Why is the link
3:24:33
between physics and information
3:24:33
so tight? Wheeler dedicated his
3:24:38
life to the pursuit of
3:24:38
fundamental questions.
3:24:41
Ultimately, he reached the
3:24:41
conclusion that everything is
3:24:44
information, quotes. It from bit
3:24:44
symbolizes the idea that every
3:24:50
item of the physical world has a
3:24:50
bottom, a very deep bottom, in
3:24:54
most instances, an immaterial
3:24:54
source and explanation that
3:24:59
which We call reality arises in the
3:25:00
last analysis from the posing of
3:25:03
yes no questions and the
3:25:03
registering of equipment evoke
3:25:06
responses. In short, that all
3:25:06
things physical are information
3:25:12
theoretic in origin. JOHN

Quote, now I am in the grip of a
3:25:22
new vision that everything is
3:25:27
information. The more I have
3:25:27
pondered the mystery of the
3:25:30
quantum and our strange ability
3:25:30
to comprehend this world in
3:25:34
which we live, the more I see
3:25:34
possible fundamental roles for
3:25:37

bedrock of physical theory, john

Archibald Wheeler and John's

3:25:49
The answer is easy if reality is
3:25:54
computational information lies
3:25:54
at the heart of computation. In
3:26:00
the end, all that computers do
3:26:00
is process information. So to
3:26:05
say computation is the
3:26:05
foundation of reality is another
3:26:09
way of saying information
3:26:09
processing is the foundation of
3:26:12
reality. Quote, the burgeoning
3:26:12
field of computer science has
3:26:17
shifted our view of the physical
3:26:17
world from that of a collection
3:26:21
of interacting material
3:26:21
particles to one of receiving
3:26:23
network of information. And

quote, Paul Davis in the Flexi
3:26:29
laws of physics 2007
3:26:33
quote, what we can learn from
3:26:33
these reconstructions is that a
3:26:37
few simple and intuitive
3:26:37
constraints on encoding and
3:26:41
processing of information will
3:26:41
automatically lead to aspects of

the Hilbert space formalism of

observation is fundamental.

Observation also appears to have

a fundamental role in reality,

quote, the universe and the

3:27:10
moment you say that the universe
3:27:15
exists without any observers, I
3:27:15
cannot make any sense out of
3:27:19
that. You need an observer who
3:27:19
looks at the universe. In the
3:27:24
absence of observers, our

recently, physicists have

speculated that the observers

profoundly different view of

cosmology and the relation

between cause and effect. top

3:28:33
which one essentially traces the
3:28:33
history is backwards from a
3:28:36
space like surface at the
3:28:36
present time. The no boundary
3:28:40
histories of the universe thus
3:28:40
depend on what is being
3:28:43
observed, contrary to the usual
3:28:43
idea that the universe has a
3:28:47
unique observer independent
3:28:47

to explain the Goldilocks factor

define the histories and laws of

3:30:52
in the view that all

computational histories exist,
3:30:55
observation does play a role in
3:30:55
selecting both histories and

physical laws. It is a tautology
3:30:59
that observers only find

imaginable program exists,
3:31:12
implementing every imaginable
3:31:12
set of laws, then in a very real
3:31:16
sense, the observer does force
3:31:16
reality to select both the laws
3:31:20
and history they observe, quote,
3:31:20
to derive the effective laws of
3:31:25
physics, one needs to do
3:31:25
statistics over the ensemble of
3:31:29
identical observers. This
3:31:29
involves performing summations
3:31:34
over the multiverse, but these
3:31:34
summations are with a constraint
3:31:37
that says that some given

observer is present. And quote,

3:32:03
he could insert himself. The
3:32:03
external world and his inner
3:32:07
world are for him only two sides
3:32:07
of the same fabric, in which the
3:32:11
threads of all forces and of all
3:32:11
events of all forms of
3:32:15
consciousness and their objects
3:32:15
are woven into an inseparable
3:32:18
net of endless mutually
3:32:18
conditioned relations. And
3:32:23
quote, anagarika given the in
3:32:23
foundations of Tibetan mysticism
3:32:27
1969. Reviewing the evidence, we have
3:32:30
found evidence in support of
3:32:35
this theory. The existence of
3:32:35
infinite computational histories
3:32:39
predicts many features of
3:32:39
reality. It predicts a universe
3:32:44
of inviolable, but simple,
3:32:44
mathematical and life friendly
3:32:48
laws. It predicts a multiverse
3:32:48
of parallel histories, infinite
3:32:53
computational complexity, and a
3:32:53
fundamental unpredictability as
3:32:57
we find in quantum mechanics.
3:32:57
The theory predicts a universe
3:33:02
that evolves in time has simple
3:33:02
initial conditions, and appoints
3:33:06
that we can't retract beyond the
3:33:06
beginning. Further, it predicts
3:33:11
information and observation are
3:33:11
fundamental. So far, all of
3:33:16
these predictions are confirmed
3:33:16
by current physical and
3:33:19
cosmological observations. For
3:33:19
the first time in history,
3:33:23
humanity has an answer to why we
3:33:23
exist that is backed by physical
3:33:27
evidence, conclusions. Given the
3:33:27
observational evidence, we have
3:33:33
reason to suspect that this
3:33:33
theory or something close to it
3:33:37
is correct. It implies we live
3:33:37
within the total set of all
3:33:42
computations. Moreover, we have
3:33:42
traced the existence of this set
3:33:47
to something that's a strong
3:33:47
candidate for having necessary
3:33:50
existence, self existent truths
3:33:50
concerning numbers and their
3:33:54
relations. Quote, one option
3:33:54
following Leibniz and others is
3:34:00
that we reach a level at which
3:34:00
further explanation is not
3:34:03
required, because something is
3:34:03
necessarily true. Shawn Carolyn,
3:34:08
why is there something rather
3:34:08
than nothing? 2018
3:34:14
this truth not only seems
3:34:14
causeless but because from it,
3:34:18
we can deduce much of physics it
3:34:18
is also a candidate for being
3:34:22
the cause. Quote, the Supreme
3:34:22
task of the physicist is the
3:34:27
discovery of the most general
3:34:27
elementary laws from which the
3:34:30
world picture can be deduced
3:34:30
logically. Max Planck in Where
3:34:34
is science going 1932.
3:34:39
Under this theory, the most
3:34:39
general laws from which we can
3:34:43
deduce the world picture become
3:34:43
the laws of arithmetic. Thus,
3:34:47
arithmetic as a theory of
3:34:47
arithmetical truth becomes a
3:34:51
theory of everything. This
3:34:51
brings a whole new meaning to
3:34:55
Leopold Kronecker is edict God
3:34:55
made the integers all else's the
3:34:59
work of Man, quote. This is why with
3:35:00
churches thesis and the quantum
3:35:06
confirmation of the mechanism,
3:35:06
intuitive arithmetic, aka number
3:35:10
theory and its intentional
3:35:10
variants may well be the
3:35:13
simplest and richest theory of
3:35:13
everything that we can have at
3:35:16
our disposal. Bruno Mars shell
3:35:16
translated from computability
3:35:21
physics and cognition 1998.
3:35:25
This theory, arithmetic has been
3:35:25
under our noses the whole time.
3:35:31
Quote, behind it all is surely
3:35:31
an idea. So simple, so
3:35:35
beautiful, so compelling that
3:35:35
when, in a decade, a century or
3:35:41
millennium, we grasp it, we will
3:35:41
all say to each other. How could
3:35:46
it have been otherwise? How
3:35:46
could we have been so stupid for
3:35:50
so long? JOHN Archibald Wheeler
3:35:50
in how come the Quantum 1986
3:35:58
the journey here, it's been a
3:35:58
long road to reach the point
3:36:03
where humanity can
3:36:03
scientifically address the
3:36:05
question, why does anything
3:36:05
exist? Humans have walked the
3:36:10
earth for some 500,000 years,
3:36:10
but only in the last 1% of that
3:36:15
time, or the past 5000 years
3:36:15
have we had writing? Only in the
3:36:21
last 0.1% of that time? All the
3:36:21
past 500 years? Have we had the
3:36:26
scientific method? And only in
3:36:26
the past 0.01% of that time, all
3:36:33
the past 50 years has humanity
3:36:33
known about universal equations?
3:36:38
To get an answer to our question
3:36:38
require that humans discover
3:36:42
numbers, equations, computation,
3:36:42
and wrestle with topics of the
3:36:46
foundation of mathematics,
3:36:46
including consistency,
3:36:49
completeness, and decidability.
3:36:49
In the end, this led to our
3:36:54
discovery of universal equations
3:36:54
that define all computation. To
3:36:59
find evidence linking this
3:36:59
computational reality to
3:37:02
physics, humans have to discover
3:37:02
the expanding universe and
3:37:06
gather evidence of the Big Bang.
3:37:06
We also have to prove the
3:37:10
smallest scales and through
3:37:10
careful study of particles
3:37:13
discover the quantum nature of
3:37:13
reality. A century ago, we had
3:37:18
none of this understanding. A
3:37:18
strange answer. We can't help
3:37:24
but notice how strange this
3:37:24
answer is. Perhaps we should
3:37:29
have expected this. Would we
3:37:29
expect that the final answer to
3:37:33
the greatest mystery of the
3:37:33
cosmos would be ordinary quote.
3:37:38
Now, my own suspicion is that
3:37:38
the universe is not only clearer
3:37:42
than we suppose, but clearer
3:37:42
than we can suppose. JBS Haldane
3:37:48
in possible worlds and other
3:37:48
essays 1927.
3:37:53
Quote, whatever may be the truth
3:37:53
about the universe, it is bound
3:37:58
to be astonishing. Bertrand
3:37:58
Russell,
3:38:02
quote, We will first understand
3:38:02
how simple the universe is when
3:38:07
we recognize how strange it is.

Tegmark cautions against
3:38:18
rejecting theories just for
3:38:21
being weird, and admits he would
3:38:21
be disappointed if the answer
3:38:26
weren't a bit weird. Quote. It's
3:38:26
very important for us physicists
3:38:31
to not dismiss ideas just
3:38:31
because they are weird, because
3:38:35
if we did, we would have already
3:38:35
dismissed atoms, black holes,
3:38:38
and all sorts of other marvelous
3:38:38
things. And actually, you know,
3:38:43
when you ask a basic question
3:38:43
about the nature of reality, you
3:38:46
know, don't you expect an answer
3:38:46
which is a bit weird? I think
3:38:50
anything but weird would be a
3:38:50
big letdown. And quote, Max

Quote, I believe when the

history of science is written,
3:39:08
then what's being discovered
3:39:12
about our universe in the last
3:39:12
decade or two will be one of the
3:39:15
most exciting chapters and

quote, Martin Reese in what we
3:39:20
still don't know, are we real

3:39:26
we now have viable answers to
3:39:26
great questions of existence.
3:39:32
Liabilities question, why is
3:39:32
there something rather than
3:39:35
nothing? Einstein's question, why is the
3:39:37
universe so comprehensible?
3:39:43

Hawking's question what breathes
3:40:03
fire into the equations. It
3:40:09
required us to assume math
3:40:09
rather than matter is
3:40:12
fundamental. Given the evidence
3:40:12
supporting this view, we might
3:40:16
consider the 2400 year old
3:40:16
debate between Plato and
3:40:21
Aristotle is settled. Quote, if
3:40:21
we do discover a complete
3:40:26
theory, it should in time the
3:40:26
understandable in broad
3:40:29
principle by everyone, not just
3:40:29
a few scientists, then we show
3:40:34
all philosophers, scientists,
3:40:34
and just ordinary people be able
3:40:40
to take part in the discussion
3:40:40
of the question of why it is
3:40:43
that we in the universe exist.
3:40:43
If we find the answer to that,
3:40:47
it would be the ultimate triumph
3:40:47
of human reason for then we
3:40:51
should know the mind of God.
3:40:51
Stephen Hawking in a brief
3:40:55
history of time 1988.
3:40:59
Hawking believed if could
3:40:59
discover what breathes fire into
3:41:02
the equations, then we should
3:41:02
know the mind of God. But do we,
3:41:08
by postulating infinite, eternal
3:41:08
mathematical truth as the
3:41:12
ultimate explanation and the
3:41:12
cause and source of reality?
3:41:15
Have we succeeded in explaining
3:41:15
God? Or have we explained God
3:41:19
away? open questions. Wireless
3:41:19
theory provides answers to many
3:41:25
questions, it does not answer
3:41:25
everything, and much additional
3:41:29
work is required. Room for God.
3:41:29
This theory provides a purely
3:41:35
natural and rational account for
3:41:35
why anything exists. Is there
3:41:39
any room for God in this
3:41:39
picture? We now have a view of
3:41:44
reality where everything emerges
3:41:44
from absolute truth. This
3:41:48
infinite truth embodies all
3:41:48
knowledge. Being a container of
3:41:52
all knowledge, as well as all
3:41:52
mines and things can we compare
3:41:56
this infinite set of truth to an
3:41:56
omniscient mind? This truth is
3:42:01
infinite and in comprehensible,
3:42:01
eternal and indestructible.
3:42:05
Without a beginning or end. It
3:42:05
is uncreated and self existent.
3:42:10
It is transcendent, immaterial,
3:42:10
imminent, and indivisible. It's
3:42:16
the reason and cause behind all
3:42:16
things. It serves as the
3:42:21
creator, source and ground of
3:42:21
being supporting us in the
3:42:25
material universe. Does this
3:42:25
infinite truth or omniscient
3:42:29
mind lead to the existence of
3:42:29
God? might even be God? It's not
3:42:35
a simple question. But knowing
3:42:35
why anything exists leaves us in
3:42:40
a better position to answer
3:42:40
questions about what exists and
3:42:43
what doesn't. See, Does God
3:42:43
Exist? deriving physical law?
3:42:51
How much of physical law can we
3:42:51
derive from the assumption of
3:42:54
all computations together with
3:42:54
the requirement of life
3:42:57
friendliness? can we predict
3:42:57
things like types of particles
3:43:01
and forces or the dimensionality
3:43:01
of space time? might we even be
3:43:06
able to predict values of
3:43:06
constants like particle masses
3:43:10
and force strengths? quote, what
3:43:10
really interests me is whether
3:43:16
God could have created the world
3:43:16
any differently. In other words,
3:43:21
whether the requirement of
3:43:21
logical simplicity admits a
3:43:24
margin of freedom, and quote, by
3:43:24
Albert Einstein,
3:43:30
it remains to be seen how much
3:43:30
of physical law is universal
3:43:34
applying to all observers in all
3:43:34
computational histories, and how
3:43:38
much is geographical depending
3:43:38
on which histories an observer
3:43:41
belongs to, quote, as a
3:43:41
theoretical physicist, I would
3:43:47
like to see us able to make
3:43:47
precise predictions, not vague
3:43:50
statements that certain
3:43:50
constants have to be in a range
3:43:53
that is more or less favorable
3:43:53
to life. I hope that string
3:43:58
theory really will provide a
3:43:58
basis for a final theory and
3:44:01
that this theory will turn out
3:44:01
to have enough predictive power
3:44:04
to be able to prescribe values
3:44:04
for all the constants of nature
3:44:08
including the cosmological
3:44:08
constant, we shall see. End
3:44:13
quote, Stephen Weinberg in
3:44:13
dreams have a final theory 1992.
3:44:20
But this hope of deriving every
3:44:20
aspect of physics is waning. Max
3:44:26
Tegmark recounts as recently as
3:44:26
1997, the famous string theorist
3:44:32
at viton told me that he thought
3:44:32
string theory would one day
3:44:35
predict how many times lighter
3:44:35
an electron is than a proton.
3:44:39
Yet when I last saw him at
3:44:39
Andrei Lin's 60th birthday party
3:44:44
in 2008, he confessed after some
3:44:44
wine that he'd given up on ever
3:44:48
predicting all the constants of
3:44:48
nature implications if all
3:44:54
computations exist, and if those
3:44:54
computations explain our
3:44:58
observed reality, it leads to Many surprising implications.
3:45:00
The universe is a dream. The
3:45:05
theory lends support to the
3:45:05
ancient idea expressed by Taoist
3:45:09
Greek and Christian
3:45:09
philosophers, and a tentative
3:45:12
Hindu and Buddhist belief that
3:45:12
the material universe is a kind
3:45:16
of dream or illusion. It implies
3:45:16
that the material and physical
3:45:21
are byproducts of mind. Quote,
3:45:21
collective karmic impressions
3:45:27
accumulated individually are at
3:45:27
the origin of the creation of a
3:45:31
world. The outside world appears
3:45:31
as a result of the acts of
3:45:35
sentient beings who use this
3:45:35
world. The creator of the world
3:45:40
basically is the mind the 14th
3:45:40
Dalai Lama in beyond dogma 1994.
3:45:49
quotes for the things which one
3:45:49
thinks are most real, are the
3:45:53
least real plotinus in the any
3:45:53
ads, five 511 to 70 ad.
3:46:01
Only recently have modern
3:46:01
scientists began to embrace this
3:46:05
view, with a few even doubting
3:46:05
the realness of physical
3:46:08
existence. Niels Bohr said,
3:46:08
Everything we call real is made
3:46:13
of things that cannot be
3:46:13
regarded as real. In an
3:46:16
interview, Marvin Minsky
3:46:16
admitted, we don't know that we
3:46:20
exist because maybe we adjust
3:46:20
what a program will do if the
3:46:23
computer were turned on, and
3:46:23
it's not even running. We live
3:46:27
in a simulation. The simulation
3:46:27
hypothesis and simulation
3:46:32
argument raise the question of
3:46:32
whether or not we inhabit a vast
3:46:35
computer simulation. If we exist
3:46:35
as a consequence of mathematical
3:46:40
truth, the simulation hypothesis
3:46:40
is made true by default, for we
3:46:46
will then find ourselves living
3:46:46
within the infinite set of
3:46:49
computationally generated
3:46:49
histories. This blurs the
3:46:53
distinction between virtual
3:46:53
reality and real reality? It
3:46:58
remains an open question, is
3:46:58
anyone in control of the
3:47:01
simulation we happen to be in?
3:47:01
See, are we living in a computer
3:47:06
simulation? Our Place in
3:47:06
reality? With an answer to why
3:47:11
anything exists, we can
3:47:11
orientate ourselves in reality,
3:47:16
we now understand our position
3:47:16
and place in it. Mathematical
3:47:21
truth implies the existence of
3:47:21
all computations. The existence
3:47:26
of all computations implies the
3:47:26
existence of all observers. The
3:47:31
existence of all observers leads
3:47:31
to a quantum mechanical reality
3:47:35
populated with all possibilities
3:47:35
and ruled by simple laws. So
3:47:40
what exists, almost everything
3:47:40
in reality becomes so big and so
3:47:46
comprehensive, that it includes
3:47:46
everything and everyone that can
3:47:50
be every thought that can be had
3:47:50
and every experience, every
3:47:56
story and scenario plays out,
3:47:56
eventually, in somewhere.
3:48:00
Actually, they all recur an
3:48:00
infinite number of times.
3:48:05
Indeed, in this view, reality is
3:48:05
so large that it guarantees the
3:48:09
existence of an afterlife. See,
3:48:09
is there life after death?
3:48:15
quote, confession. If I love
3:48:15
this theory, it is because it
3:48:20
entails the existence of many
3:48:20
things not physically present,
3:48:24
notably those incredible deep
3:48:24
universal dreamers which keep
3:48:28
losing themselves in an
3:48:28
incredible labyrinth of
3:48:31
partially shareable dreams,
3:48:31
meeting ladders and ladders of
3:48:35
surprises, self multiplying, and
3:48:35
self fusing, and which are
3:48:39
partially terrestrial and
3:48:39
partially divine creatures. And
3:48:44
quote, Bruno Mars shall in
3:48:44
discussion list 2011
3:48:50
reasons study of the mysteries
3:48:50
of existence has brought us to a
3:48:53
coherent theory of why there is
3:48:53
something rather than nothing.
3:48:58
The best evidence suggests our
3:48:58
universe is one malong an
3:49:01
infinite number of possible
3:49:01
realms with the full extent of
3:49:04
reality being unbounded. The
3:49:04
source of this reality is
3:49:08
logical necessity, via infinite
3:49:08
mathematical truths which are
3:49:12
independent of any material
3:49:12
universe. We can count ourselves
3:49:17
among the first generation of
3:49:17
humans able to reason logically,
