able for time travel?

So far time dilation is possible in the forward direction. That is if YOU travel away from earth in a very fast spaceship near the speed of light then turn around and come back. The people on earth would age more then you have. YOUR clock would be different then those people on earth. It would be faster.\n\nGoing backward in time is still up there.\n\nThere are many experiments that prove this to be true. Atomic clocks capable of high accuracy are sync up. One is put on a plane and flown around the earth at high speeds for a long time. When the two clocks were compared later, they showed a difference, a very small difference but a difference none the less.\n\nTake a look at this website. There are plenty of other site out there.\n\nhttp://imagine.gsfc.nasa.gov/docs/ask_astro/answers/050225a.html\n\nInterestingly, if you did travel at the speed of light, you would be anywhere and everywhere all at once... WOW! That blows my mind.    :-)

Time travel is actually 100% possible.  You're time travelling right now, the problem is that you cannot control how to time travel.  \n\nIf you had enough fuel on a spaceship that could go at 99% the speed of light, the time on the spaceship is slowed down dramatically, this is called time dilation, which means your biological clock also slows down, slowing your aging process.  If you come back to Earth by travelling 60000 light-years, you're only 40 years older then, but the Earth and everyone on it is 60000 years older.\n\nTime travelling to the past is currently not possible.

according to einstein's theory of relativity, if you are able to travel at a speed faster than that of light then you will be able to travel back into time. got my point? if you leave earth today at 1 million km/hr, then you will be back on earth before you started out(means you will have travelled back in time) it cannot be said in which year you will return because there is no relation for this case. but good luck with your time travel!!!

I have done time travel. Evertime I come back to California from Japan. I leave around 16:00 in Japan and get home around 09:00 . Sounds like time travel to me.

I would travel thru time

Time travel is possible. It has been proven with the use of atomic clocks placed on the earth and on board spacecraft which show a difference in time because of the difference of speed between the two parties. The faster you move in space, the move time that passes on earth.

Traveling into the future is possible.  Going back through time, however, is not.

See my answer to the question "Is time travel a possibility?" especially the part about other universes

you can go back to the future

Possible now!\nwe go forward in time 1 day every day.

You first have to decide what you mean exactly by 'time travel'. In one sense *everyone* is travelling into the future at the rate of 60 seconds every minute. No big deal. If you go  on a journey at a speed close enough to the speed of light, and return to the earth, you will have aged less than those on the earth by an amount that depends on how fast you were going. So, it is theoretically possible to spend 10 subjective years and come back 30 years in the future. We know this is possible from special relativity and we see effects along this line everyday in particle accelerators. The only problem is getting to high enough speeds. So if you regard this as time travel, there is very concrete proof that such is possible.\n\nBut the real question about time travel is whether you can *return* to your original time. Technically, that involves travelling in a 'closed, timelike curve'. While there are theoretical possibilities for such curves, nothing concrete along these lines has *ever* been seen. Furthermore, some theorists think that such curves are flat out impossible. So if this is what you require for time travel, then there is no hard evidence that it is possible.

well its theoretically feasible to go forward in time but not backwards, but with today's technology its not very doable.

Actually, the current theory on time travel is that the furthest back into the past you can travel with a time machine is to the point that the time machine was created.\n\nAccording to this theory, to travel back into the past, you would need to create two worm holes.  One wormhole would exist at the time that you turn on the machine and the other worm hole would be put somewhere to 'age'.  At some time in the future, something could be put into the wormhole in the future and it would come out in the past.

I don't think it is possible.  If it was possible, it could sure mess up current events...or would it mess them up or fix them and what would the consequences of their actions be in the long run.  Hypothetically, it can be quite a conundrum really.  I really don't think that we, as humans, have even the remotest possibility of messing with time.  It is, and will remain, in the realm of fantasy and science fiction.

Well this one is interesting.  Mathematics tell us that to move in time, one must move faster than the speed of light.  There are particles that do move that fast so it is theoretically possible.\n\nWith that having been said, I'll go back to the particles that move faster than light.  These particles cannot be seen or measured in any way that we can figure out but we know that they exist because of the reaction of other things.  ( its like the wind blowing,  you dont see it but trees and stuff react to it )\n\nOne theory suggests that if we do manage to travel back in time,  we wont be able to interact with it at all. ( I dont understand all the mechanics on this one)  But it would be like being an invisible ghost.  You could observe things and events but couldnt make actual physical contact with anything thus you couldnt change events.

Time travel is possible. Theoretically.  According to some theories, there are random tears in the fabric of space-time.  Some researchers have even interviewed people who have had experiences of "lost time" and weird visions such as seeing things that were there one moment but gone the next only to find out that the particular thing they had see there only exsted in a time before.

Time travel is impossible. Find someone who taped it. Put up a card at the grocery store and leave a number. Maybe you'll meet a nice guy and GET A LIFE!!
