In order to qualify, shouldn’t an “observer” have a specific awareness, or understanding of the experiment at hand (whether it be Schrodinger’s cat, the double slit, etc.)? I’m not sure that a cat, a vial of poison, or a detector could observe or collapse anything . . . but I do suspect that these things, like most objects, are regularly collapsed by means of Probability. In this way, Probability is a kind of “observer.” That is, Probability really exists (with or without the existence of humans), it’s the specific idea of how things collapse (evolve) in each moment, any idea is an awareness in the truest sense, so could Probability itself be a specific awareness necessary to collapse an object?
Has anyone explored whether a cat, a nematode—or a QM-unaware human for that matter—could bring about (“observe”) the wave or particle result of a double slit experiment?
