Do you ever wake up thinking, here we go again? Same stuff, different day? What many of us call "Groundhog Day" but physicists call a "Causal Loop" or "Time Loop". This idea has been used as a plot device in many movies and series like "The Day After Tomorrow", "Russian Doll", "Palm Springs". The one that kind of got it all started, the aforementioned "Groundhog Day", the 1993 comedy classic where cynical weatherman Phil Conners, played by Bill Murray, wakes up in the same day over and over and over again...until he can figure a way out. So who better to take us through it than the writer of "Groundhog Day", Danny Rubin. He joins Peter and Richard to discuss "What If you were stuck in a time loop?". Stick around for philosopher and author of "Paradoxes of Time Travel" Ryan Wasserman as he breaks down the science of time travel in some of your favourite sci-fi classics.
