Is multiverse actually a thing? Any proofs at all? I'm asking because it looks more like a religion tier bullshit. Making up some shit to explain something.

basically theoretician fap stains

Its theory blown way out of proportion. Like all science.

it's theoretical physics that's become so commonplace that many people think of it as actual physics

there's precedent for it in the sense that we thought a lot of things were unique (our planet, then the sun, then the galaxy) so who knows

that and the simulation argument. But there's no empirical proof for the multiverse theory no.

I think a multiverse is just logical.
Space doesn't make anything in singles. There's not just one planet, there's not just one solar system, there's not just one galaxy and there's not just one cluster of galaxies out there.

There's probably not just one universe out there either.
I imagine a black ocean where big bangs are happening all over the place, like rings on the water if you're throwing sand or gravel in a lake.

And maybe if you "zoom out" from that level there are more of those "black oceans" out there,
like galaxy clusters.

OP asked for proof, anyone can imagine anything, the question is whether its true

the multiverse right now seems like a completely ad-hoc hypothesis

I guess but, again I just think it's logical.

I like the simulation idea but can you imagine the complexity of the project and the energy and technology required to actually make a
simulation of this universe. Actually programming time, matter and laws of physics, the detail of it all down to every unique little particle and atom in our entire universe.

But then again, the universe is old. Who knows what type of super advanced civilizations have come and gone. Maybe we are living in
a simulation of some godlike ancient civilization. Wonder if they've
wondered if they are living in one themselves.

it seems more logical by that line of thought to assume that there is a larger galaxy composed of galaxies, and another after that and so on

Thats the interesting part of the simulation arguement. If you were to create an ancestor simulation it really wouldnt matter unless that simulation was currently being observed by consious entities. So as long as nobody is watching the universe simulation can run very rough calculations for things like orbiting bodies, galaxy motion, etc. Only when things are being observed by beings who would otherwise notice, does the simulation actually need to process things down to an atomic level. Then you have strange things like particle wave duality, and the delayed choice quantum eraser experiment, and we actually start to see the lack of precision universe "rendering". Whether the universe is a simulation or not it does seem like when you get to the subatomic level, things like position and momentum aren't really real until it has some impact on an external system. If you want to make that simulation even easier to run, you dont even have to simulate the entire universe. You only have to simulate the brains of consious entities in said universe and the stimuli they encounter. This is a feat we are not far from being able to accomplish with current levels of technology, and it fixes the whole "you can only simulate a universe thats smaller than the one you inhabit" problem.
