the information paradox.

Tweet

Stephen Hawking recently came up with a solution to his infamous Information Paradox that considers the concept that the universe we live in may only be one of an infinite number of parallel universes, each with its own laws of physics. In some, black holes existed. In others, it did not. In effect, Hawking claims, the universes with black holes cancel out with those without them. This made the information paradox dissapear because, ultimately, no black hole means no problem in the first place. Now, call me old fashioned, but that makes absolutely no sense to me. It seems as if Hawking is going from one crazy idea to another. My confusion is threefold. 1. Basically Hawking is saying that black holes both exist and don't exist at the same time. Even for the baffeling world of physics, that sounds absolutely rediculous. 2. If black holes are cancelling out under this theory, why aren't other things? Matter and antimatter supposedly cancel out, but they're in the same universe. Suppose there were a universe where matter did not exist, just energy. Why isn't that universe cancelling out with the matter of our universe, causing matter to dissappear? 3. If black holes ultimately disappear under this theory, why is it that we still have them? If they disappear in theory, shouldn't they disappear in practice as well, otherwise it's not scientifically valid? Can someone PLEASE help me out here!
