Interesting that you should mention Hindu. That, and Buddhism philosophies (ideologies, religions whatever) fit well with these theories in that there is that whole circle of life and death and rebirth theme throughout each one. An ultimate "Nirvana" as is the case in Buddhism might be equivalent to the utopian time line of our single atom racing back and forth through time, perhaps even the very goal of the atom's journey in the first place. And what happens if the atom stops its journey through time? Does time stop? If so, is time merely an abstract creation as a result of the atom's existence?
You know Josh, i never thought I would philosophize about this kind of thing when I was younger. Thought it was a waste of time. Probably still is a waste of time, but its fun as hell to speculate without having to do any real difficult research (other than looking up some stuff in books or on the net).
