If the Universe Spun
I have been reading Michio Kaku's new book, Parallel Worlds and he mentions something that I never came across before.
He points out that many things around us spin from tops, to hurricanes, planets, galaxies and quasars. but the universe itself does NOT spin.
"When we look at the galaxies in the heavens, their total spin cancels out to zero. (This is quite fortunate, because, as we see in chapter 5, if the universe did spin, then time travel would become commonplace and history would be impossible to write.)" P. 95.
Can't wait to get to chapter 5.
