If you want to see fear in the eyes of a quantum physicist, mention the word “measurement.” — Folk saying
Is reincarnation possible from a scientific, rationalist point of view? For my purposes today I’m going to argue that it is. We will never, however, be aware of it, and indeed “we,” as we like to think of ourselves, will be completely out of the picture. I’m going to approach the problem from the point of view of quantum mechanics–a field about which I understand almost nothing, although discussing it permits others to assume I have gone mad.
Let’s begin, for the sake of argument, by saying that when you get right down to the bottom–under the turtles–everything, and I mean Everything, consists of quantum particles. These particles can as well be in one place as another, even at the same time. As Wikipedia informs us: The Everett many-worlds interpretation, formulated in 1956, holds that all the possibilities described by quantum theory simultaneously occur in a “multiverse” composed of mostly independent parallel universes.
The crucial word here is “simultaneously.” I take it to mean that Everything can be thought of as being in no particular place at any particular time. If you choose to think of it that way, be my guest. Whatever you think will be sublimely irrelevant, because places and times are concepts we bring with us to the quantum level. They do not seem to exist there. Or if they do, they are created only in the act of our applying them, and our measurements have meaning to us but not to them.
