Weeeee!
I don't like your username, but I like your message.
If that is true maybe that means that it actually is finite and has a center. And the rotation and light speed put an upper bound on its size.
Then again the expansion of space doesn't care about such mundane things as a cosmic speed limit so the universe rotation probably won't either. Or the extents just slow down.
And if everything is rotating, and most is rotating in the same direction, it means we're probably in a black hole.
Science is going to be interesting during the next twenty years.
Black hole cosmology makes the most sense to me. But what do I know, I’m just a burnt out stoner.

I think that if space itself is what is rotating, then speed of light limit does not apply. But if it's everything in the universe orbiting, as it were, a central point, then it would.
But if it is space itself rotating, then that would suggest some objective frame of reference outside the universe. Wouldn't it?
You might be onto something.

Wow, so maybe the universe really is centered around me after all. Take that, 1st grade teacher! j/k.

How does this manage to bypass the need for a center to the Universe?
Obviously it's spinning in four dimension space. Like living on the 2D surface of an inflating balloon that is rotating, there is no "center" from the perspective of us lower dimensional scrubs.
Ok. So hear me out. What if said 2D universe is spread out on the inside of said balloon and the spinning is happening on two axis? Wouldn’t that make gravity the result of centrifugal force? And what if the balloon is actually flexible, so that the heavier stuff stretches its surface outwards (thus warping time and space around it)?
I’m no scientist but that’s how I’ve often imagined it. Although it’d have to be in an even higher dimension for more degrees of freedom on rotation? No clue there.
No clue haha but that is a neat idea. Also my explanation probably wouldn't really explain centrifugal force to offset the hubble tension.
There was also a scishow or spacetime video about how gravity can be seen as an emergent property of "time / causality is slower the nearer the gravity well", and that is how gravity works. To truly understand it you have to understand the math and how to solve it, afaik our explanations are all rather imaginary. So you could probably interpret the math to mean that this "spacetime bulging" is the result of a spinning universe.
The bigger question is: Where is the rest of the matter that spins in the other direction? It should have perfectly canceld each other out! (like matter and antimatter also didn't)

A center in two dimensions, in three dimensions an axis, in more dimensions...
Scientists propose a lot of stuff. A lot of these proposals are contradictory to each other.
Still cool.
considers things moving at very close to the speed of light uses Newtonian mechanics
It’s an interesting idea but this is a pretty massive oversight.
Forgive me for strawmanning but you know some idiot is going to say this contradicts "scientists'" claim that the universe is 13.8 billion years old
If it indeed rotates, this raises another question: What does it rotate around, i.e. where is the center of the universe? How does our position in the universe relate to this center, or which (known) structures have we observed there. Could it be the Great Attractor?
spiral ever increasing outward, wouldnt the center represent the big bang
Because time isn't linear or whatever and its still expanding (I have no idea what im talking about)

Actually it's just toilet water. Slow motion flushing.
It's toilets all the way down!

So it's about 3 universe months old? Pfffft, baby.
I like the one where we live inside of a black hole, and a black hole is a gateway to another universe
Not the most useful of gateways though if you have to be smushed to go through it.
I believe the correct term is "spaghettification" and it's not your ordinary everyday spaghettification, but one that happens at an atomic level.
As long as you find a black hole that leads to the spaghetti universe, it would be fine

If you drink enough it won't take 500 billion years to rotate. In fact, you'll have to hold onto the grass to keep from falling off the planet.
Science is cool.
Cool theory. But should not work if the universe is much larger than what can be seen though? Unless it’s just our visible part of the universe is rotating in a mind boggling large structure? And why not? All matter clumps, and a huge universe should have countless structures that are the size of all we know
I think as telescopes get better we just keep noticing bigger structures. Maybe this is just the biggest one we know right now.
I feel like it'd take some amazing statistics and millions of years of data to detail out structures larger than our observable universe.
