General Science / Relativity?

« on: 20/08/2009 00:19:53 »

Although, this question can be called "fool question", i think, if you are-scientists-genius, maybe, you want to "WOW".
Ok, my theory,
"if time is relative, all things in the world can go future, go back, up to you. Now i imagined with the "destiny". We can go future like a seek in your vid player. We can go back like a seek in my mp3 player. I think, all of this, happened, because of "recorded world". Our behavior aren't our behavior. It like destiny and cassette. Could you understand and tell me about this?
