Why is the multiverse so popular in sci-fi at the moment?

“The Multiverse is a concept about which we know frighteningly little”, warns Doctor Strange in Spider-Man: No Way Home, but it is a concept that has become rather familiar on screen. 

The Sorcerer Supreme’s next adventure will see him navigating the wonders and dangers of the Marvel multiverse, but he isn’t the only one exploring infinite realities – several of the movies in our upcoming sci-fi movies in 2022 guide are diving into the multiverse. Michelle Yeoh will be fighting throughout different universes in the A24 produced Everything Everywhere All At Once, before Miles Morales returns to travel across the multiverse in, err, Spider-Man: Across the Spider-Verse (Part One).
