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.

I thought the general consensus was that it IS finite and has a relative center point?

Nah in the past it looked like a pretty homogeneous mass when zoomed out enough. I assume this center of rotation is no more of a "pure center of the universe" than our sun is.

I'd imagine its just a local maximum for gravity.
