True, but there is nothing special about plane waves in that regard, whenever a physicists makes a mathematical model he always ignores many things, one example would be effects that decrease asymptotically so much they become unmeasurable. Models are always simpler than the reality, if they weren't there would be no point in making mathematical models. Physics is more complex than mathematics and for that reason I think a mathematical sphere is an approximation of a physical ball, but Bruno thinks a physical ball is an approximation of a mathematical sphere. On this point at least I was under the impression that you agree more with me than Bruno, but maybe not. > > *as far as I am concerned the MUH is easily falsified, and why it > continues to interest people is baffling.* Brian Greene lists 9 different types of possible other worlds, Hugh Everett's Many Worlds is # 3. There is no rock solid proof for any of them but I think 8 of them are reasonable hypotheses, but MUH is a step too far for me.
