Physics, cosmology, and the ultimate nature of reality. Is our Universe infinite—or finite, but wrapped in higher dimensions? Janna Levin, renowned theoretical physicist and science communicator, explores bold ideas about the cosmos: the possibility of a finite universe, the nature of extra dimensions, and how abstract mathematical truths might constrain the physical world.
In this wide-ranging conversation, Levin considers whether the Multiverse is physics or metaphysics, whether the laws of physics are fixed or contingent, and if the universe is fine-tuned for life. Could the Big Bang have been just one of infinite cosmic bounces? Are the deepest truths of existence determined by necessity, chance, or brute fact?
Levin’s latest book, “Black Hole Survival Guide”, is an evocative exploration of black holes, provoking us to imagine the visceral experience of a black hole encounter illustrated with original artwork. The book is available for purchase now: https://amzn.to/4cVzn9n
