Could someone explain Jan-Markus Schwindt's idea, published under the provocative title Nothing happens in the Universe of the Everett Interpretationplease? Frankly I can't even understand the opening paragraph of the abstract. http://arxiv.org/abs/1210.8447 Since the scalar product is the only internal structure of a Hilbert space, all vectors of norm 1 are equivalent, in the sense that they form a perfect sphere in the Hilbert space, on which every vector looks the same. The state vector of the universe contains no information that distinguishes it from other state vectors of the same Hilbert space. I don't get that. The state vector has direction. In fact that's all it's got. But it's a direction relative to any arbitrary basis. I don't think I'm misinterpreting Schwindt's meaning as he goes on to identify a way of factorizing the space, where each branch "peacefully rotates" and nothing else happens. He calls these Nirvana frames. But I'm out of my depth with tensors and I find it hard to extract the logic from Schwindt's exposition so can someone explain what it all means?
