First, I was already on board with all the content of this post. My question is this: would there be any difference, or would it help resolve any confusion for anyone, if instead we said something like “There is still just one ‘world’ in the sense that there’s one universal equation constantly following the same rule. The math shows that that world consists of many non-interacting parts, and the number of non-interacting parts grows with time. For convenience, when performing experiments, we ignore the non-interacting components, just like we already ignore components outside the experimental system, only now we also re-normalize to exclude the non-interacting components”?
