Kiiiind of. I suppose we haven’t definitively ruled out a geometric centre, but it runs up against Occam’s Razor in a really big way. A centre of the universe would require some kind of boundary or edge to the universe, and the physical dynamics of how that would even work are very much non-trivial.

Generally the universe is thought to either loop back on itself like the surface of a globe, or extend infinitely in every direction.

The big rip scenario happens in the case where the rate of space expansion is increasing. It’s possible, but we haven’t seen any evidence of it yet, so far the rate appears constant, which means a heat death scenario.

They wouldn’t; the expansion of space isn’t strong enough to change the distance between atoms; the force holding them together overcomes it.

Effectively, yes

There actually isn’t a center of the big bang, every point is expanding away equally.

Turns out, no; every point is expanding away from every other point, so every point sees itself as the center of expansion.

and now it is capitalist.

The USSR hasn’t existed for 35 years you arrogant fucking western dipshit.

No actually, you’re just a racist making assumptions.
