It is the natural cycle of life for things to be born only to die at a later date. Worlds are just like that. This is one fact about the worlds that you have already discovered, or at least theorized about. In the famous problem, a cat is placed in a box with a random item that will kill it when it is knocked over. Is the cat alive, or dead? Many speculate that it is decided and fixed when you open the box. Others say that the world splits into two when it is opened. Most agree that the cat is neither alive nor dead, and that it is not yet decided. This is how new worlds are created- Any time a single variable can change the flow of a world, whether it is small or immense, the world duplicates.
