Interest in the multiverse theory, suggesting that our universe is just one of many, has spiked since the movie Everything Everywhere All At Once was released. The film follows Evelyn Wang on her journey to connect with versions of herself in parallel universes to stop the destruction of the multiverse. The multiverse idea has long been an inspiration for science fiction writers. But does it have any basis in science? And if so, is it a concept we could ever test experimentally?
Featuring Andrew Pontzen, professor of Cosmology at University College London, Katie Mack, Hawking chair in cosmology and science communication at the Perimeter Institute for Theoretical Physics, and Sabine Hossenfelder, research fellow of physics at the Frankfurt Institute for Advanced Studies.
This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware. Social media and platform production by Alice Mason, sound design by Eloise Stevens and music by Neeta Sarl. A transcript is available here.
