>People talk about how stuff like Many Worlds is too outlandish
>Read up on inflation theory
>mfw Inflation leads to a literal infinite universe, where after a certain distance things are so far and different that it might as well be a new universe anyways
I don't get it. Why dismiss a theory for being outlandish when even our most well grounded and observationally supported theories of the universe lead to outcomes JUST AS OUTLANDISH?

Half integer spin is too outlandish to exist as well and yet it does exist.

How about this: a
The universe exists as a 3-dimensional "sheet", and this sheet is capable of being manipulated on the 4th dimensional axis. Photons are particles that are rotating and moving on the 4th dimensional axis (hence the illusory "wave" movement pattern). They have no mass because mass is a result of moving on the 3rd dimensional axis, and by those standards photons are technically not moving at all.

Well “spin” itself is just an analogy to classical rotation so some of that strangeness is just going to be the analogy breaking down

To the extent that half integer spin can't be generated from orbital angular momentum, that is true. That's not so outlandish, however. What I meant was outlandish is the behavior of half integer spin states under rotations of the lab frame being such that turning a physical device upside down only rotates the half-integer spin state trapped inside it by 90 degrees. This is basically the definition of "too outlandish to exist," IMO. It's far more outlandish with many worlds which fundamentally doesn't conflict with anything familiar.
