are you a time traveler?

no sorry I just don't have the time for it right now....

Theoretically, time travel is possible. But current technology does not permit it. An interesting article appeared in Popular Science a while ago on time travel physics (see link). You're right about the stars - in that we're not looking at them in real time. In a similar vein, light from the earth reaches outward into space. An alien civilisation looking at us from far away through a telescope could theoretically view our past history. But light also weakens the further it gets away from its source, so to really look way back into our past, we'd need a really powerful instrument to detect such light patterns.

of course in the future, its the only time i havent been to yet.. anybody who who wants to go back to the past must have something in the present to regret about.

Time travel is very possible. You are travelling in time right now, but just at a slow pace.  If you move a lot faster than someone else you will be travelling in time slower than they are.  But if you travel at 95% of the speed of light for 10 years (relative to you), you'd have travelled 11 and a half years relative to someone who is not travelling with you!  This is due to a phenomenom called Time Dilation and is part of Einstein's Theory of relativity.  \n\nYou could say you have travelled 1 and a half years in the future over 10 years.  If you travel even closer to the speed of light for the same amount of time you would have travelled even further into the future.  The equation for time dilation is T=T(0)/(sqaure root of(1-(v/c)^2)).  Where T is the time according to someone staying still, T(0) is the time according to you, v is the speed you are travelling, and c is the speed of light.\n\nTravelling back in time is not yet proven to be feasible but it is thought, by many major scientists believe it would involve bending the universe (which may or may not be possible depending on the type of universe we have) or travelling to a parrallel universe, which would really on have the affect of time travel.\n\nOne major flaw of all these is that returning to the time of your original place is impossible or hard to do.

I think that there is the theory that you could travel back in time, but it is really all Star Treckie.  I don't think there is any possibility of travelling back in time, no matter how fast you can go.

You would need a time portal machine

Well in all simplicity, if that were fact then yes it would be conclusive proof.  But can you state that we have never encountered a time traveler with any margin of accuracy?  I think not.  If technology ever reached the point of time travel, there is good reason to believe that philosophy and laws of that time period would dictate how our future friends would carefully act in their past (our present).  The same laws (along with technology) would also, most likely, prevent folks from misusing time-travel technology.\nAlso, I don't think we can accurately predict what sort of effects it would have on non-time travelers.  (I mean, you and me, the people who don't "go anywhere" in time)  Who knows weather we time-bound folk would have any way of perceiving the effects a time-traveler would have on the time line?

Yes, it is very possible. If I had told people about my time travel experience, they would call me a retard. In year 2003 or 2004, I don't remember which year it was, I had kind of like the time travel experience reliving the same day. The same exact things happened to me in two straight days. It was the most weired experience I have ever had in my life. Yeah, reliving the same day.

According to Einstein, it's only possible to travel time to the future, although he never said that going back in time is impossible.\nTime slows down for you and your vechicle as you travel close to the speed of light (186,000 miles per second).  Anything outside is at normal time and speed obviously.\n\nTheoretically, if you travel 30 mins out into space at the speed of light and travel back to earth, you're only an hour old (by the way, at that speed, you've traveled an equivalent of six of our solor systems).  However, as you return to earth get ready to meet your great great grandson.\n***\nI don't know why.\nIf I did I'd own this freaking corporation.  *L*

yes - i can travel forward in time already

Time travel is possible when we travel forward not backward. IF you look to the history books there are no such thing of human come form the future. So that is the proof that has defined the theory that we can't go to the past. There are theory that we can move forward by using the method of speed. Once you increase the speed of travelling the time will change very fast, and you might be in the future. But to have that kind of machine to bring you forward needs a lot of discovery especially about the strenght of metal, fuel, speed, and a lots more. You can get the theory about speed from einstein. Whatever you want to know about it, you can get it there, BUT eventhough you learn about time travel, you won't get that technology while you still alive. Maybe you can use that information just for you knowledge. Not more than that.

I have not seen or met a time traveller. However their is such a thing as a gauche horizon. Basicaly when you create a time machine you cannot travel back before the time machine was created. So sence as far as I know, no time machine has been invented as of yet. It would be impossible for a time traveller from the future to experience what life is like in our historical period. For instance if the time machine was created in 2500 they may start having time travellers from the future coming back for anthropological surverys. However they could not visit 2006 because the time machine was not yet invented.

if you already have a time machine, then go...\nyou can find your wife but i guess  you can't go back to the past to change the future...\nhave you seen the movie "The Time Machine"?... it's very nice....

I haven't.But.......\n\nTime travel has been a popular science-fiction theme since H. G. Wells wrote his celebrated novel The Time Machine in 1895. But can it really be done? Is it possible to build a machine that would transport a human being into the past or future? \nFor decades, time travel lay beyond the fringe of respectable science. In recent years, however, the topic has become something of a cottage industry among theoretical physicists. The motivation has been partly recreational-time travel is fun to think about. But this research has a serious side, too. Understanding the relation between cause and effect is a key part of attempts to construct a unified theory of physics. If unrestricted time travel were possible, even in principle, the nature of such a unified theory could be drastically affected....

There are some strange solutions to Einsteins field equations which some theorists claim to offer the possibilty to travel backwards in time but these are pure hypothesis.\n\nFor one of these possibilties you would need a huge amount of "strange matter" which we yet even don't know what it is exactly, other of these hyothesis would allow to travel back in time, but not past the invetion of the thime machine, since this time machine is the "exit" on the other side of the "time tunnel".\n\nOther scientists say it will never be possible, for varios reasons, one of the most mentioned is the problem with causality (althogh there are again theories that that would't be a problem) another very funny one is by Stephen Hawking: There never will be time machines, becaus if it would we would see tourists from the future all the time.\n\nSo, seriuosly, don't expect to see a working time machine during your lifetime.

I don't accept the premise that a time machine is possible, therefore I can't answer such a question, even hypothetically. I can give you a proof that time travel into the past is impossible. It goes like this. If time travel into the past were possible, then at some time in the future, the means to travel into the past will be developed. That being the case, then we could expect to have been visited by time travelers from the future, but we have not. Ergo, time travel into the past is impossible. However, time travel into the future is possible. From the time I started typing this answer, up to now, I have traveled into the future about two minutes. However, it is still now. It is always the present. Always and forever.

hi, well if i could change one thing i would want too go back in time so that i could fix all the stupid mitakes i have made in the past. i know that might sound crazy, but theres alot of mistakes i have made. catcha ps great question!
