I can't seem to wrap my head around the basic concept of the Schrodinger's cat experiment, the one in which a radioactive particle is either emitted or not emitted, a device is either triggered or not triggered, and the cat is both alive and dead (in a superposition of states) until one of us opens the box and looks inside. It seems anthropocentric to think that nature needs us to observe something in order to have a definite outcome. It's as though the universe should not have existed until conscious life evolved in order to witness it. For one thing, I've always assumed that the term "observer" really meant "interactor" or, any photon or particle that interacts with another photon or particle. I assumed that the thing that would collapse the superposition is the atom that absorbs the radioactive particle (or doesn't) and triggers the cat's death (or doesn't), if not the atom emitting said particle, let alone the cat itself, or the atoms making up the box itself, which would interact with the heat (or lack thereof) or even the minute amount of gravity produced by either the dead or live cat. By the logic used in this thought experiment, if we put the box with the cat inside an even bigger box with a human in it, then the human could look in the box and collapse the superposition for him or her, but to everyone else outside the second box, the cat is both alive and dead and the human who looked inside the box has seen both a live and a dead cat...at least until another human looks inside the box containing the first human along with the box containing a cat. And if the human in the second box is to broadcast the results to everyone on the planet, then to those aboard the International Space Station (who have not heard the news), does the whole planet Earth exist in a superposition of two possible states where the entire human population has heard of both the dead and the live cat? Where does it end? If this is not the case, then neither can it be the case that we need to look inside the box to have a definite live or dead cat. Could someone explain what I'm missing?
