The Multiverse puzzles me. First it was used in fiction, Michael Moorcock, depicting an eternal battle between the lords of chaos and law. The Queen of the swords is still one of my favs. Then confusingly, in physics, when Schrödinger said that when his equations seemed to describe several different histories, these were "not alternatives, but all really happen simultaneously". Perhaps it's me, but since quantum theory physicists seem to have started talking in riddles.
