Or is a legacy medium just promoting it uncritically because no one who thinks pays attention to it anymore?
“It’s absolutely possible that there are multiple worlds where you made different decisions. We’re just obeying the laws of physics,” says Sean Carroll, a theoretical physicist at the California Institute of Technology and the author of a new book on many worlds titled “Something Deeply Hidden.” Just how many versions of you might there be? “We don’t know whether the number of worlds is finite or infinite, but it’s certainly a very large number,” Carroll says. “There’s no way it’s, like, five.”
Carroll is aware that the many worlds interpretation sounds like something plucked from a science fiction movie. (It doesn’t help that he was an adviser on “Avengers: Endgame.”) And like a Hollywood blockbuster, the many worlds interpretation attracts both passionate fans and scathing critics.Corey S.

The multiverse makes physics so cool that it is indistinguishable from self-indulgence.
