going faster just means aging slower.

hhmm...sound nice, interesting

Really it is quite simple to prove, that it is impossible to travel backwards in time.

step 1: If time travel were possible, humans would eventually figure out how to do so.
step 2: Humans from the future would travel back in time.
step 3: No humans have traveled back in time as of yet.
step 4: Therefore time travel into the past never becomes possible.

You are obviously someone from the future trying not to mess up the time-space continuum by letting us know there is time travel in the future.

Interesting

but:

there must be an origional existance where no one has ever travelled back in time, when they do travel back in time it will create a seperate dimension. meaning they will still have memories of the origional dimensions.

example you go back in time to kill your own father (accidentally lets hope), yet you still exist.

or you go back and kill hitler before WW2 but you still remember the world where hitler dies during WW2.

in other words we are in the origional/yet to be split dimension. or we are in another one that is not near as bad as the origional which we do not know. -there are many possibilities.

(Please further explain yourself in order to prove things to me either through logic or facts)
1. You make a large presumption that there are alternate dimensions.
2. You seem to propose that alternate dimensions are created infinitely, but don't you think that creating something like a dimension would consume a lot of energy? Something cannot be made from nothing, the creation of a new dimension would consume all the energy of the previous dimension, hence ending one and creating another, there can only be one.
3. Neither of your examples can be logically deducted to a satisfactory means as true scenarios.
(if you went back in time and killed you father, that means you would never be born. if you are never born you cannot go back in time and kill your father. what happens next is we have an impossible situation, naturally speaking you must be both fully dead and fully alive at the same time, an occurrence impossible by the laws of nature. Nature is commanded by set laws which prevents impossible scenarios for itself, therefore the laws of nature must restrict time travel into the past, in order to prevent the occurrence of an unresolvable paradox within nature itself).

If you would like further explanation regarding anything on my part just let me know and I will try my best, I enjoy intellectual debate and look forward to any response.

not possible.

what's done is done

Actually there are quite a lot of models that treat time just like space. Examples, Minkovsky space and Euclidean space -- they treat time in the direction as they do space, so if you are able to simply turn around and back wards in space you should be able to do so in time as well.

Space travel backwards in time may be physically impossible -- but theoretically there must be a way to do so. What julius is trying to get at, is, what if paradoxes are just limitations of our own mind? Nature doesn't know whos who. If i went back and killed my father before I was conceived, well I wouldn't disappear since i distinctly remember being conceived -- but at that point I would become "this man's murderer", not his son. This is what julius was saying by flinging around the word dimensions. Perhaps they exist, perhaps they don't -- but shouldn't necessarily assume that these paradoxes are the limitation of time travel, they are most probably just human limitations.

It's funny how BovineDesi considers himself the only person to detain the absolute truth.
