[Moderator's note: this discussion has been spun off from another thread.] This is probably a silly idea, but I haven't got any reputation to preserve, so I'll mention it anyway. My very limited (and probably very wrong) understanding of quantum theory tells me that until something is observed, it hasn't actually happened one way or another, but remains a probability distribution. If there is no way for a person outside the black hole to make any observations which would distinguish the possible cases for the distribution of matter inside the black hole (shell outside the EH, shell a millimetre inside the EH, singularity at the centre, small sphere of matter around the centre etc.), then could it be said that none of those things is actually the case, but rather, just some sort of probability distribution? While I'm here and on the topic, I might ask another related question that I've never been able to find the answer to. I understand that, for Schrodinger's cat to stop being alive and dead and go into just one of those states, it has to be observed. But does it have to be observed by the scientist who put him in there, or will some other human do? Will the cat do? (because the cat will know when the poison is released)? Would a severely handicapped person with the same IQ as the cat do? Would a robot do? Or some kind of simple sensing device inside the box that will activate when the cat falls over, but not send any message out of the box? Or if the janitor sneaks a look when the scientist is out of the room, could it be that the cat is dead for the janitor, but still alive and dead for the scientist - is the cat's state subjective?
