YES! Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future.\n\nNewton's most important contribution to science was his mathematical definition of how motion changes with time. He showed that the force causing apples to fall is the same force that drives planetary motions and produces tides. However, Newton was puzzled by the fact that gravity seemed to operate instantaneously at a distance. He admitted he could only describe it without understanding how it worked. Not until Einstein's general theory of relativity was gravity changed from a "force" to the movement of matter along the shortest space in a curved spacetime. The Sun bends spacetime, and spacetime tells planets how to move. For Newton, both space and time were absolute. Space was a fixed, infinite, unmoving metric against which absolute motions could be measured. Newton also believed the universe was pervaded by a single absolute time that could be symbolized by an imaginary clock off somewhere in space. Einstein changed all this with his relativity theories, and once wrote, "Newton, forgive me."\n\nEinstein's first major contribution to the study of time occurred when he revolutionized physics with his "special theory of relativity" by showing how time changes with motion. Today, scientists do not see problems of time or motion as "absolute" with a single correct answer. Because time is relative to the speed one is traveling at, there can never be a clock at the center of the universe to which everyone can set their watches. Your entire life is the blink of an eye to an alien traveling close to the speed of light. Today, Newtonian mechanics have become a special case within Einstein's theory of relativity. Einstein's relativity will eventually become a subset of a new science more comprehensive in its description of the fabric of our universe. (The word "relativity" derives from the fact that the appearance of the world depends on our state of motion; it is "relative.")\n\nWe are a moment in astronomic time, a transient guest of the Earth. Our wet, wrinkled brains do not allow us to comprehend many mysteries of time and space. Our brains evolved to make us run from saber-toothed cats on the American savanna, to hunt deer, and to efficiently scavenge from the kills of large carnivores. Despite our mental limitations, we have come remarkably far. We have managed to pull back the cosmic curtains a crack to let in the light. Questions raised by physicists, from Newton to Kurt Gödel to Einstein to Stephen Hawking, are among the most profound we can ask.\n\nIs time real? Does it flow in one direction only? Does it have a beginning or an end? What is eternity? None of these questions can be answered to scientists' satisfaction. Yet the mere asking of these questions stretches our minds, and the continual search for answers provides useful insights along the way.

Hoax.\n\nTime travel is almost certainly impossible in our universe (the whole cause-and-effect thing). And there is certainly no time travel machine. Even if the machine was secret, some of the physical basis for such a machine would be known. And its not.

You can travel to the past but you can not travel to the future BECAUSE it did not occur yet.\nCheck the latest Physics web sites on this topic of time travel

Time travelling is a very difficult topic.\n\nYou can supposedly travel into the past if you travel faster than the speed of light but this involves getting a source of infinite energy as when matter gets closer and closer to the speed of light its mass will dramatically increase.\n\nThis is said to be very unlikely but general relativity says it may be possible on highly unusual circumstances.\n\nWormholes, permitted by general relativity,  could be possible only if it is traversable.\n\nIf you read general relativity and objects at speed of light you get time, space and gravity based dilations where light appears to be bent by gravity and arrives at an object at different times.\n\nYet again the object has to be travelling at 0.99c or faster!!\n\nI says time travel will never happens but i wish it would.

yes. everyone is a time traveller. in fact, even now you are travelling from a past to a future. the present is but a trasistory period of your journey.

According to Einstein, time travel like that which you are speaking is impossible. It revels in the laws of circular contradiction. Allow me to explain: If you were to go back in time and kill your grandfather, your parents would cease to exist and therefore you would cease to exist. But if you never exist, you cannot go back in time to kill your grandfather and he would therefore CONTINUE to exist and eventually you would be born into his lineage. Though time travel is impossible according to Einstein, he firmly believed that time VIEWING was completely possible. As for why you ask these questions, Einstein has no answer. Though Descartes might as he coined the phrase "I think, therefore I am." So perhaps you just "are", and that is why you ask these questions.

I don't think it is possible, and if so the experiment itself would probably detroy the fabric of our reality to the point that people's answers would disappear, and reappear as different answers. The time machine does make for some fine fiction, though.

i don't think this is the best we can do but dude think about it, even we want to advance, the environment does not allow it because we are gradually running out of resources. I know we have everything figured out but come on, our ultimate life source, the sun, is generally going to explode into a super nova.\n\nPerhaps we can find a new planet to live but not until someone invent a spacecraft that can get us out of this solar system and into other galaxies.\n\nlet me think of these inventions...hologram...maybe...time travel...impossible.....but i do believe in time viewing when we travel thousands times faster than the speed of light and go to a distant planet and observe the light reflected from Earth  thousands of  years ago.\n\nAs far as this generation is concerned, technology is only going to improve as much as more memory space on a mp3 player. But who knows, maybe tomorrow there will be another revolution like the industrial revolution and change our lives forever.

Based on the relativity theory, there are many studies that are taking place to look into the possibility of traversing the time-space continuum.  As far as I know, we're not quite there yet.  But if and when we are, we should be able to tap into the theoritical "worm-holes" to go into different points in space without having to exume too much time.

My opinion is that in order to travel through time we would need to be able to travel uncalculable extraordinary distances.\n\nImagine how fast the earth is moving through space. Not only would we need to calculate the speed of the Solar System; but the speed of the Milky Way Galaxy; the speed of the Universe; and in which direction.\n\nWhy would we need to know this? We would need to be able to travel to the actual physical position in which the Earth would be located at the time in which we were desiring to be present.\n\nIt is my opinion that if it were not for the fact that we are traveling at such and such a speed that "Time" itself would not be possible in the first place.\n\nThe fact that physical matter is never in the same location;;;EVER;;; is what I believe makes the existance of matter a possibility.\n\nImagine that if the Earth were a hundred miles away from its current location in just one small second of time. To travel back one second in time you would have to travel that one hundred miles of distance.\n\nWould the Earth be there if you could travel that distance? Some scientists want to believe that "worm holes" can link up huge distances in space by folding or warping space, distance, and time. \n\nI personally believe that God has the power to time travel; or how else could he know the future in order to prophesy; and I do believe he has proven the ability to prophesy. Yet, did he time travel, or did he make things happen according to his prophecy?\n\nOk; if God exists in the future; or at the end of time (the furthest point in which time has yet reached since the beginning of all time) and has the ability to travel back into various points of the timeline; he then has the ability to travel forward and backward in order to see how well things are going according to his own actions.\n\nSo then, Jesus would have seen everything before it ever happened. I also take into account that God must have the ability to be larger than the Universe and smaller than the smallest forms of energy and matter if he were truly capable of producing and controlling them.\n\nYet affording us free will is what allows us to be who we are.\n(see references below)\n\nIs it possible that matter is frozen in time at every location along the path of which it travels? In other words; Is our history preserved as if it were a tape or recording throughout all of its existence? It does not seem possible; but anything is possible with God. Maybe this is where the "Missing Universe" energy is located; frozen in time. If this were true than I believe it may be possible to time travel. One would have to have the ability to travel amazing distances at amazing speeds.\n\nI would have to believe that traveling into the past would be possible under the circumstance that matter becomes frozen in place as it travels and that a person could travel such distances and had much time available for the journey.\n\nSo if traveling into the past were possibe; because the past would be there; whereas the future may not be yet, would traveling into the future be possibe?\n\nAfter traveling backward, surely we could then travel back to the future from where we just came from. This theory would conclude that we exist in the "real" present and the future really has not happened yet.\n\nSo traveling into the future could only happen if we first traveled back into the past, and then went back to the future.; where we came from.\n\nSo lets say someone else traveled back from the future (which has not happened yet to us; because at which point do we cease to be the "real" point in which time has already existed?) into our present time. We would have to consider that if God really does prophecy by time traveling, then we do not currently live in the "real stream of time"; but time and history has already taken its course and has already been fulfilled.\n\nIn other words; we do not live in the real present; but

Time travel at least in the sense of viewing the past events is possible. This can be done with meditation, remote viewing,scrying, Dream work, past life regression, psychic vision or hypnosis. Most people can learn. I have done it and know many others who have also done it. It is also possible to veiw created realities too. Yes psychic veiwing often reveals  things very different from the accepted view. \nFor example,remote viewing of the Crucifition shows around 40 crucifixions on the site at that time rather than three.\nThis is probably historically correct . \n Rather than being confusing this is usualy liberating and has a quality of rightness that was missing from the conventional version. Biblical  historical events are often quite different from taught versions. Some of these psychic perceptions have been confirmed by archeologists and historians.

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

There is no such thing as time travel, it's a physical impossibility. The reason we haven't had any visitors from the future is because time travel simply cannot occur.

Yes, if there were no such thing as time.\nJust for fun, try to imagine that there is no such thing as time. I think human thought/existence is very difficult without the concept of time. If time doesn't exist, then everything that has happened, is happening and will happen is right now!!! Is that possible?

I think it could be possible. Even though some people ask why someone doesn't come back and tell us this, if you came back in time and told everyone this, how would you know what effect it would have? What would probably happen it that they when it's invented, nobody will be able to use it, and then it might as well not exsist. There's irony for you.
