Is there only one past? You know the theory or whatever that says your past self hasn't done this yet. I was thinking wouldn't there have to be a past realm for EVERY second?

Say you pick up a can and hold it in the air. Wouldn't there be a past for when you first pick up the can and every millimeter or inch you had moved it there would be one that was almost to the top holding it in the air, one in the middle holding it in the air, one just starting to pick it up....and so on. Same for the furture, where technically you would be the past?

I don't know if I am making sense or if anyone will get this but...um yeah....
