It is stated in some interpretations of QM (exceptionally to mention Copenhagen interpretation) that an object stays in superposition (SP) as long as not a human (good physicist– just kidding) brain observes it and so projects it on a definite state (dead/alive). But as I think the following very simple example disproves this statement. I consider a working clock in a closed room. It was left at 2 o’clock and it is not observed (even put in vacuum to avoid decoherence induced by the medium) – e.g. closed there for 2 hours and then by entering the room one sees of course that it is showing 4 o’clock instead of 2 o’clock. But according to the above mentioned interpretations every instant it must have been in a superposion of showing the next second or not. If observation is what causes it to move then there were not such and hence it must still be showing 2 o’clock. (analogously as the cat is both dead/alive) So I think this disproves the statements for staying in SP until a brain or environment appears to project it. Do you agree?
