Your comment presupposes that the Everett interpretation cannot be true. But it offers an explanation of the appearance of collapse without having a collapse.

Your comment presupposes that the Everett interpretation cannot be true. But it offers an explanation of the appearance of collapse without having a collapse. Namely if a quantum mechanical observer observes a quantum mechanical system in a superposition of states, we get a superposition of quantum mechanical observers who can no longer meaningfully interact, each of which observed a different state of the quantum mechanical system. This is exactly what the Schrödinger equation predicts MUST happen. As a side note, this is the most popular interpretation of quantum mechanics among cosmologists. It turns out that if you're using quantum mechanics to explain things like the birth of galaxies, taking seriously what quantum mechanics says for human sized quantum mechanical systems becomes very easy.
