Hi, I'm an 11 year old kid so I won't get any mathematics too complicated, but I don't want an answer simplified too much. So in schrodingers cat experiment, the cat and the Geiger counter used to detect the decaying atom do not decohere the system because they are a part of that closed system. But then i say, if we want to know what's going on inside that box, couldn't we just replace the cat with a person, and the poison with something less lethal? Would the person inside the box just have one version of himself sent to a parallel universe, with the other version stepping out of the box with a definite answer as to what happened inside? But that would have to mean that a conscious person had both if his superpositions collapse, ergo having two states of himself exist in the group of universes we supposedly live in. So is this experiment possible? Would we get the disappointing, seemingly classical result I suggested? Ty!
