Where exactly do the probability distributions we observe come from under the many worlds interpretation? I know it has something to do with being the only stable configurations in Hilbert space but I don't understand why. This is my attempt to explain it in my own way, please tell me if it makes sense: If four dimensional universes are separated perpendicularly by a fifth spatial dimension then couldn't it be that particles persist through the parallel universes as a fifth dimensional string and that the points on the string closer to our four dimensional universe would be more likely to have an effect than further points? It seems like if that were true that the probability spectrums would look something like what they do. I'm not a physicist so please don't throw math at me, it's too scary. Thanks!
