Okay, so to go back in time , you must go back in a physical form right? And you must also use some machine to transport you through the warp, correct?
Well, if those are two absolutes, than to go back in time you are bringing matter with you. Whether it be your self or a machine of some kind, you are bringing matter with you. Since the matter that forms you and the machine are already present in the past, just in a different form, then you are really creating matter, correct? And when creating that matter, there is a big frigging explosion, since you just formed matter that already existed. Therefore, you die.
However, when you go forward in time, with such a machine, you will not die form a big boom. The reason being, when you leave your time period to go forward in time, then you left a gap in matter where you and your machine used to be. This would create a gap in time, but only until the time in which you get back, at which point the gap will be refilled.
I don't even believe in time as a concept - just because we can measure and record it doesn't make it a physical quantity - far as I'm concerned, there's one big point of existence and we're all invited.
time is the 4th dimension. there is length, width, height, an time. saying you dont believe in time is saying you dont believe in the 1st three dimensions.
It may be possible to travel through time if parallel universes exist. Simply, one would jump to that universe and then jump back to this one at a different point in time. This way, one would not be restricted to the timestream, moving forwards at a constant rate, and could simply pick a timeframe they wished to join.
Of course, this also relies on time being one big string of...well, time. Time, of course, is relative to whichever being is in question - Einstein's Theory of Relativity provides solid evidence towards this - and hence it may also be possible for a being to stop within the timestream, or exit it as such.
as long as we are going backwards, it is impossible. i will prove this through an experiment that stephen hawking did. http://www.youtube.com/watch?v=zOezD5zguQo watch and learn. it will blow your mind, and end this discussion. all 5 parts are crutial.
