eli5: “choice” in the Many Worlds theory.

346 views

From what I’ve read, according to the Many Worlds theory, every time I make a choice, a new universe springs into being in which I make a different choice. But what constitutes a choice? Does it have to be a conscious, binary choice? For example, there are a large number (infinite?) of things I’m NOT doing right now, including running around my workplace naked except for clown makeup. Does that mean that there’s a universe in which I am doing that? And am I just getting lucky to keep ending up in the universe in which I’m behaving well? Or does the theory only apply when I have to actually consider what to do next? (Until now I’ve never considered running around naked at work with clown paint on).

The idea is that anything that can happen does happen, even mutually exclusive events, they just happen in alternate realities. Is it possible that a radioactive decay causes a brain cancer that results in you running around your workplace naked in clown makeup? Call it a low probability. (still infinitely many, if it’s possible at all, but very much a smaller infinity than the ones that don’t run around naked in public with clown makeup on).

Of the universes have someone recognizable as you in it, most of them are probably pretty similar.
