INTRO: You are one of some billion people on this planet. This planet is one of some hundred billion planets in this galaxy. This galaxy is one of some hundred billion galaxies in the universe. Is our universe the only one? Or are there other universes? In the past decades, the idea that our universe is only one of many, has become popular among physicists.
