A pleasant presentation of facts that looked into diverse range of subjects ( Black Holes/ Jeans / Pennies’ worth / Thomas Edison ) interjected with jokes and comedic statements to lighten the conversation. Who would have thought that massive stars explode into what is called Massive Failures ? Also, Supernovas blow out into black holes, but these black holes are actually smaller in size than massive failures; Ironic, isn’t it? Another noted fact is that Thomas Edison best friend was Henry Ford who bought a wheel chair when Thomas Edison was confined to a chair as he got older . Why? So that, they could wheel race together! Such an enjoyable listen!
