Thanks David. Even Feynman said:-"I think it is safe to say that no one understands quantum mechanics. Do not keep saying to yourself,.... "But how can it be like that?" because you will get "down the drain" into a blind alley from which nobody has yet escaped."-I think it can 'be like that' because QM is describing entities that are not contained within spacetime. These are what I call 'physical possibilities', after an idea by Heisenbert that he didn't pursue. Most physicists assume that 'physically real' = 'living in spacetime'; I'm suggesting that this should be questioned. Physical reality need not be restricted to the spacetime manifold.- Again, for dhw -- I'm not saying other things (such as mental phenomena) are not real. But for now, I'm not considering them as physical things (but I don't rule out that they could be, on some very subtle level that is not a known part of any current physical theory).
