If you're a fan of multiverse movies, this episode is for you. The many-worlds interpretation of quantum mechanics says that an infinite number of universes exist in parallel to eachother, each having branched off in a moment of divergence before following its own unique timeline.

Theoretical physicist Sean M Carroll guides us through the strange and sometimes daunting topic of quantum mechanics – from Einstein and Bohr to Schrödinger's cat and the many-worlds interpretation.

This talk was recorded from our theatre at the Royal Institution on 22 January 2020.
