This strange behavior doesn’t apply only to light. If you were to get in a rocket and blast off through a rotating universe, you, too, would get caught up in the rotation. And because of that rotation, your movement would double back on itself. When you returned to your starting point, however, you would find yourself arriving before you had left.
In a manner of speaking, a rotating universe would be capable of rotating your future into your own past, allowing you to travel back in time.
