Tony: Althea, do you believe in the future? I mean, that there really is a future for you, your children, Mankind.
Althea: Yes, of course I do.
Tony: And obviously you believe in the past, everybody does. But what if I were to tell you that the past and the future are the same? You think I'm raving.
Althea: No, no, I don't.
Tony: I don't blame you. Suppose I told you that Time itself doesn't exist. It's only motion we measure, the motion of the Earth spinning, the orbit of the Earth around the Sun.
