Evidence of the Multiverse

For most of us, the word “multiverse” probably conjures up some sort of fun sci-fi episode like the universe in which we all have hot dogs for fingers in Oscar contender ‘Everything Everywhere All at Once’ or the parallel universe in Star Trek where there’s an evil you with a moustache.

Multiverses are just vehicles for our flights of fancy, right?

Well, that’s what we thought until Professor Will Kinney casually mentioned that the majority of physicists now accept that we live in a multiverse in an interview with us earlier this year.

Laura Mersini-Houghton is a Professor of Theoretical Physics and Cosmology in the Department of Physics and Astronomy at the University of North Carolina at Chapel Hill and author of 'Before the Big Bang: The Origin of the Universe and What Lies Beyond', she is also one such physicist, and furthermore, she says she has the evidence to back it up.

She joins Jonathan to discuss.
