Hi there, I'm not extremely adept at understanding what I like to think of as the "Philosophical" side of QM but I find I have a problem with some aspects of an interpretation of the wave function collapse. I also could be misunderstanding what people are saying. When people talk about particles being observed and the wave functions collapsing, It almost seems as if some people think that the observer must be a human. For example, Schrodingers cat: He is said to be half alive and half dead until observed, but doesn't the cat observe whether he is dead or not? More fundamentally i would think that solely interactions between fundamental particles would be what we call observers. I just saw in another thread something along the lines of "Well what happens if the observer dies right after taking a measurement?" on whether or not the wave function can 'un-collapse' .Am i just crazy or do some people talk as if humans have to be the ones to collapse the wave function? I don't agree with this.
