See if Sean Carroll answers the question of "weighing" worlds: *How much is too Many Worlds, is it just right?* https://groups.google.com/d/msg/everything-list/E3WLUdnW8jI/MLPg3dAhAgAJ Suppose world W branches (in reality, not in "bookkeeping") to worlds W0 and W1. If reality is pure information (basically purely mathematical bits of 0s and 1s), then that sort of "production" seems OK. But what if W is (or contains) matter. Based on matter contents of W, W0, and W1: *If the matter contents of W0 plus W1 combined is greater than the matter content of W, **how was the extra matter "produced"?* Two answers so far: 1. *If an infinity of indiscernible universes already exist at the start and are only differentiating/diverging (instead of splitting), then no matter is created, all of it was already there.* 2. *Differentiation rather that duplication of matter is one possibility, but duplication of matter is not logically impossible either. Empirically, we have that matter cannot be created, but that is within a single world.* @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
