Well, I have no doubt that consciousness is a physical manifestation or 'brain state.'
It's a pretty simple thing to test: put a human into a medically induced coma, and they are no longer conscious. Return the brain function, and voila, consciousness returns.
Anyway, clarify this: how are...
If the there is a photon heading towards the slits, but it exists in two universes, what would cause the copy in universe A to interfere with the copy in universe B? I thought these universes cannot communicate?
