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 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?
