Ok, so the earth spins around its axis, and around the sun; and the sun spins around the black hole at the center of the Milky Way galaxy; and that center spins around some other monster black hole at the galactic center of a cluster of galaxies, which, in turn spins about another monster monster black hole at the center of the center of the cluster of glaxies, etc. etc., and all this spinnning makes me dizzy. QUESTION: Ultimately, does the spinning end? Is there one mother of all black holes? It would seem that if not, then there must be an infinite number of black holes in an infinite universe.
