Does Santa exist in an alternate universe somewhere?

I know a question asking if Santa exists sounds childish but parallel universe theory is a thing. So even though Santa doesn't live at OUR north pole, does he live at the north pole in one of infinite parallel universes?

According to the quantum many-worlds interpretation, such a world would only exist if it could arise due to a random quantum fluctuation at some point in the past history of our own world—which doesn’t seem plausible in this case.

I believe in the Quantum Claus^TM^ theory - there’s just one guy, and he just makes one present for just one kid (on the nice list, which has at most just one name). But on Christmas Eve he exists in a superposition of states at every child’s house with every possible gift.

What do you think "parallel universe theory" is?

"many worlds hypothesis" in quantum physics is nothing like Sci fi "parallel universe" stuff. Sci fi is fiction. Don't get your understanding of science from Sci fi.

You are badly misunderstanding many worlds theory.

I’m using Wheeler’s version of the MWI, because it currently seems to be the most common one—but I think Wheeler’s version is a misunderstanding of Everett’s. So if that’s what you mean, I agree (although in that case I’d say “the Everettian interpretation” instead of “many worlds theory”).
