Do you think of reality in terms of different "timelines"? (sh.itjust.works)

I'm imagining like a lot of different timelines. I'm jealous of the versions of me in the better timelines, and simultaneously afraid of those darker timelines, ones even darker than this timeline.

Do y'all think of the world as different "timelines"?

Perhaps I'm too obsessed with time-travel/multiverse-theory?

Btw I read Recursion lately (time trsvel story). And I watched Dark Matter TV Series (parallel universe story). Both stories by the same author.

Every time these concepts appear in the media, my "obsession" just goes even further.

I don't like this current "depression" timeline. Very shitty.

Physicists say timelines break causality and would thus go against reality.

Isn't it time travel that breaks causality? How can even physical existence of parallel timelines break it?

Via the concept of Laplace's Demon, according to those physicists.

Laplace's Demon is just a thought experiment, and has nothing to do with alternate timelines.

Anyway, multiple timelines are definitely not incompatible with our understanding of physics and causality. Look into the many worlds interpretation of quantum mechanics. (in my opinion, the most reasonable explanation of quantum physics)

Why is adding an additional unprovable postulate to quantum mechanics (the universal wave function) and believing we live in an invisible infinite-dimensional infinitely branching multiverse more reasonable than just accepting that quantum mechanics is a time-symmetric theory?

I mean referring to the parallel universe concept. Unless everyone here believes in free will, the thinking goes universes that start out the same are going to play out the same, requiring any differences to be caused by external interference.
