Description

Over the last few years, the box office has been dominated by films like "Spider-Man: Across the Spider-Verse" that explore ideas of parallel universes, quantum worlds and alternate lives. There's some real science behind those ideas, but they may not look exactly how we imagine. Theoretical physicist Sean Carroll helps us untangle the madness from the multiverse.
