Do you believe in the theory of quantum particles (which sometimes disappear and re-appear mysteriously) vanishing into alternate universes?
What interests me about quantum mechanics is that the world of sub-atomic particles is almost its own world, governed by rules and causes that we humans barely even begin to understand (yet). The deeper you go into the physical foundations of nature, the further away from human reason and common sense you get. IIRC, Bakker said something similar about neuroscience - you get to a point where "normal" logic and common sense don't apply anymore.
(Bakker was making a point about Pavlov and the behaviorists, AFAIK. They ran into the same "wall" where the human brain's inner workings just couldn't be described by common sense anymore. Not that this has anything to do with quantum physics, just that it's a similar case of the human brain only going so far.)
