If on 6-20-06 you went back in time and killed, say , what would happen when the time line rolls back 6-20-06 and is . there would be no reason for you to go back in time to kill him if he was already killed. but if you dont go back in time on that day then you never killed him because you never traveled back in time. so if you think about it, you cant change the past because if you did you would have no reason to go back in time to change it and therefore you wouldnt go back in time which means you didnt change it.

I think I get what you're saying, but man...try to be a little bit more clear...

Time travel is impossible so you are left with two alternatives. The first is to live in the past like most people, and the second is to change your perception of the past, which is little different from seeing a new path into the future. All great philosophies and all revolutions are the result of a changed perception of the past. The world of the possible is difficult enough without the confusion of the impossible, and if you can have a clear perception of the past, and live without guilt, you should have no problem seeing the future clearly. Good luck!

there's one easy way to change the past: win and write the history book. :twisted:

what if everything that occurs is the result of time travel of the future? in that case, every conceivable plot to reverse events would be nullified because a future time travel has already altered it.
what a paradox.

Your sentence is highly debateable. For one, read about Einstein's special theory of relativity. Then, after a little more research, and when you hear about tachyons, wormholes, infinite cylinders, and other anomalies, you will see that what you said is not currently a (dis)provable fact.

Git out of dodge, hombre!

All these methods require energy beyond imagination. Then if you had the energy to travel at the speed of light and beyond you would expand absolutely, essentially becoming light with no guarantee your atoms would re-associate properly. Then, you could get to the future sooner, but to go back in time would require even greater speeds, perhaps in excess of C squared -becoming energy itself. So whether provable or not it is only a diversion from the possible, and while we know the impossible is only a degree of difficulty some things are so far beyond the possible that they will likely always stay that way: an exercise in speculation.

Talk about a reversal.
A few years back, they said you couldn't go into the future because it hasn't happened yet and now they say you can, but not the past!
But if I could go into the past and kill Hitler and came back to the exact point at which I left, nothing would have happened as I would have killed Hitler in a different universe and he had still lived in mine.

It is a matter of energy, which at present is beyond our reach. To get to the future sooner you have to travel at the speed of light or faster. The past is falling away from us at the speed of light. To catch it, and get into it you would have to travel at twice the speed of light to catch up. So far as we know the speed of light is an absolute quantity and the reason only light travels at that speed is that matter, mass, increases absolutely with absolute speed becoming in its individual parts the most basic form of energy- light.

I believe you could actually change the past. I guess in the future you would reach a point where you realize that something happened because YOU changed it..something may be going different to what it's supposed to be.

Ok..I don't really make sense. Read Harry Potter and the Prisoner of Azkaban? Childish book, whatever, but it has a point there. Go back, and do what you know it's supposed to be happening.

Time travel is possible.

The only reason why you don't see anyone from the future here.

Is because there is no future

I believe that it was Data from TNG that put time travel in the easiest terms to understand.

It is possible, but completely pointless for one to attempt to change the past, since doing so will only confirm the past you already have. It has already happened and is so and can never be undone. It may become necessary for a person to travel into the past to keep the past as it currently is. You have created the past you have, whether in the given time, or from a future date.

Data showed it through the inevitability of his own head's removal, no matter what decisions he made in the past. Since he had already made them, and will most certainly have the same options and information in the future (something that is changed only in the present), he will inevitably make the same decision he did when the destruction occured.

In simpler terms: If you were to go back to the past to give yourself information, you would already remember it occuring, and thus be forced to travel back to make sure it occured, or risk undoing it. But in remembering said action, you have confirmed that you will travel to the past in the future.

The parallel universe theory, which would require someone to remove themselves from their timeline and then travel back, is merely a sad attempt to have science-fiction emulate a complicated topic in an easily "understood" way. Trying to make true sense of such a "theory" in real scientific terms will easily turn you into the smiley above. :bang: A nice way to give youself brain damage. The upside is that you will no longer be so bothered by time travel.

I thank you have to incorporate parallel universe theory, in order to avoid such a paradox.

Indeed. For time travel into the past to be possible in the future, it would require parallel universes/chains. You would be in the same time period, but things could be radically different and wouldn't effect the period you came from. Most likely, it simply wouldn't happen.

Time travel into the future, however, would be easier. In essence, all it is is speeding up the process from now to then without you aging. The problem with it is, you wouldn't be able to go back, so you wouldn't know your limits.

But why wouldn't it be possible to take a wormhole to a parallel universe and end up in the past.

Some say control is the ability to make change. And according to Rage Against the Machine, "Who controls the present, controls the past." -Testify :wink:

If you did that, then you would have no means of getting back. You wouldnt be able to direct your travel in the first place. And there arent any parallel universes to boot.

Actually science says there are. Just as it is absurd to think that we are alone in the universe it is absurd to think that we are the only universe. these other universes are different maybe by one atom, one atom may be in a different place, and a different time. Also, there are other yous. and therefore parallel universes would be the only logical answer to any paradox that uprises in time travel talk. If someone has enough power to even generate a wormhole they have enough power to control one.
