But really, didn't people on quantum physics say that quantum particles can reach a collapsed state from their superposition when a conscious observer observes... He was trying to prove them wrong with his thought experiment... That it cannot apply in the real world.. So as opposed to the theory of the cat being both dead and alive until the box is opened, he's saying that it has already reached a collapsed state without the observer having to open the box. People are thinking his thought experiment proves otherwise.. It's not just an analogy...
