What The If?

What if the universe was stuck in an eternal cosmic Groundhog Day? Picture traveling backwards through time past the Big Bang only to discover you've looped right back to where you started - like a cosmic snake eating its own tail. Explore the mind-bending possibility that our entire universe repeats itself in endless cycles, where infinite copies of you exist scattered across millions of light years, all having this exact same conversation at different stages of cosmic evolution. Join cosmologist Niayesh Afshordi from the University of Waterloo and Perimeter Institute for Theoretical Physics, and science communicator Phil Halper, fellow of the Royal Astronomical Society, as they dive into Roger Penrose's controversial time loops and the heated scientific battles between cosmologists who engage in academic warfare. Discover the wild world where the universe literally forgets what's big and what's small, why some scientists think this cyclical cosmos is the answer to everything, while others call it pure fanta
