rule #1: be kind
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.
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?
Is this maybe related to spin of particles that was considered to be "a kind of rotation momentum how it behaves mathematically but for all we know it does not literally represent any kind of rotation"...and it turns out it does in fact represent the fundamental rotation of the universe ?
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)
If it's flat, and not curved, I think the center would be everywhere?
I can't find any flaw in this. I was trying to think of it in any way other than having an actual center somewhere. This can be my model till I understand it better.
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.
Scientists propose a lot of stuff. A lot of these proposals are contradictory to each other.
Still cool.
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)

I think Hubble tension could fit into this if the sphere/balloon is also expanding/growing/stretching away from the centre. In this case it would be the fabric of space being stretched though. So not sure how that’d fit into this model exactly.

Yeah. I think so too.

Dunno tbh. Maybe it’s double-sided and it’s on the other side of the balloon/membrane?
(And for some reason my brain associates this spinning sphere analogy with gravastars 🤔)
A center in two dimensions, in three dimensions an axis, in more dimensions...
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
I like the theory from the movie Levels :)
You wouldn't want to put the universe in a tube
