The universe moves with the energy left off from the big bang. This is why the universe constantly expands.

Things rotate and revolve because of gravity.

the galaxies outside of our own Are moving away from us and the ones that are farthest away are moving the fastest however the galaxies are not moving through space they are moving in space, Because space is also moving in other words the universe has no center everything is moving away from everything else
