There may be an endless number of worlds.
This is more of a theoretical ideal than a reality, but numerous fields of mathematics, quantum mechanics, and astrophysics have all reached similar conclusions: our world is just one among many, and we live in a multiverse.' There are several theories as to how this may happen, one of which being that atoms can only be organized in a finite number of ways in time and space, eventually leading to the repetition of events and individuals. Other ideas postulate bubbles or parallel universes, as well as 'braneworlds' that exist just outside the grasp of the dimensions we know.
