This interesting article from Space.com showed up on my Google front page.

Most interesting to me is a recent speculation I had made about the Universe rotating based on the evidence that galaxies take on an appearance similar to rotating weather depressions. A weather depression rotates because, as the air moves to balance the pressure difference, the rotation of the Earth deflects the path to the right or left, depending upon which hemisphere the depression is in. Could this be what causes galactic spin on a cosmic scale? Does it really follow that a rotating Universe would mean time travel was possible? What other effects might this have on space, time, and perception?
