Maybe it's a stupid question, so I will delete it if it will receive too many down votes but..

I was wondering about the Universe, and the fact that

  • We know it's expanding;
  • We don't know if it has an edge, maybe yes maybe no;

But.. does the Universe spin? If we should describe the entire observable Universe as a "body", we should take into account its expansion but would it be also described as a rotating body or as a non-rotating one?

The universe is constantly expanding, but not rotating. It would be possible for our universe to spin if there were several other universes orbiting in a system of their own, but that answer is in the perspective of how our solar system's planets rotate.

There are so many possibilities, but not enough definite answers.

  • A better question may be " Is there a preferred rotation axis for all the galaxies. When you look, they all appear to be in random orientation but is there a preferred orientation for the galaxies?" – Peter R Mar 14 '16 at 22:57
