Do you really think time-traveling will be ever possible?

yes - i can travel forward in time already

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.

Teleportation. We at least have theory on how teleportation could work. If the universe under discussion permits of time machines, then no time machines will be invented. The noted s/f author Larry Niven wrote a couple excellent essays on these topics, which I recommend to your attention. They will provide all the information you could possibly need.

No we cannot. The time travel stories are our over enthusiastic mind's work. It just cannot be possible. Unless we attain speed of light. Do u believe in relativity? think about it... maybe u will find answers there.

Time travel to the future is theoretically possible.  Travel in space at near-light speed for a short time and a much longer period of time will have passed on Earth.  Or you could have yourself cryogenicly frozen (though I'd wait until they perfect the revival process) and see the future that way.\n\nIt would be a good thing to see the progress of mankind, but you may have a hard time fitting in.  Since there's no way to travel backwards in time, you would be stuck there.

These answers sound pretty good.  However, if the fantasy idea were real and I looked up teleportation in the dictionary, which is based on common usage, I suspect I would find 'time travel' as the definition.\n\nWith my two cents, Teleporting would be a method of time travel, as opposed to others, I guess like OBE's.  I'm sure there would be more than one way to time travel by then.\n\nYou might not be the same person, Star Trek transported people out and back without their diseases or illnesses as a cure.  But if you did the sling-shot effect, using that method as opposed to teleporting you would be the same person.

Everything is possible but is it also likely? I don't think so..

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 you can. it takes you back in time...or you get to see the future..this is how time machines work.

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.

the answer is - it depends - on a lot of things\n\nI hate to answer a question with a question but here goes ...\n\n- do you mean in theory or in practice ??? (in [einstein's relativity] theory it is possible to travel into the future - all you need to do is to go out into space for a while - the time here on earth will continue to progress at a normal pace while time for you will progress more slowly - when you come back you'll have essentially traveled into the future - not quite a time 'machine' but same effect

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.

You cannot go into the past beyond your own birth and the future for the same reason. In both cases non-existence cannot be overcome. You may live to 100 but you have not yet so....you cannot visit yourself, there is nothing to visit. When you get to 100 you can visit yourself at 20 and so see yourself at 100 and see the future that way.\n\nTime travel  will always be limited to a persons life time i am afraid and the events that occured during it. No hunting dinosaurs, Hitler killing, Cruxifiction visiting.\n\nThis is the reason no one from the future has visited us yet. Once the future becomes the present and they invent time travel they can but only if the people who invent it and use it are alive now.\n\nGet it.\n\nIt a paradox I know but.....

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

Im afraid I do not think time travel is possible.  Einstein’s theory says that as you move faster time slows down.  The problem lies in getting to a speed that is so fast that time actually moves backwards.  Anything with mass cannot reach the speed of light, because as its speed increases the amount for energy required to push it increases, so it would take an infinite amount of energy for something with mass to reach the speed of light.  Photons have a zero-mass and therefore light can travel at... well the speed of light :)\n\nSo if it was possible to break ourselves down into zero-mass pieces then it would be possible to travel the speed of light.  What is unknown is if you could travel so fast that you could actually "turn back time" which I do not believe is possible.  Or else we would see people from the future already coming back to the past.\n\nAnd then you would get those crazy little problems of ... if you went back in time and killed yourself at say 12 years old.   How would you have ever been old enough to actually travel back in time to kill yourself... because you would have been dead...\n\nIt could be possible to slow time down in relationship to yourself, so that the earth ages faster... If you consider that time travel.  Say for example you get into your space ship, and travel near the speed of light, then the earth would age faster relative to you.  If you consider that time travel then yes I believe that is possible.  But the thought of going forward, and back in time is not possible in my humble opinion.

I would love to see time travel available, but I believe to go back and prevent a part of history would be wrong. It would change the future for everyone. I loved the TV show "Quantum Leap", but I always thought there was something wrong about changing history.

OK, first fo all Mr cliffx has it backwards.  As you continue to acellerate tworads the speed of light time will slow down for you and stay normal for everyone else.  Thus at that speeds you could travel 10000 lightyear in only 1 year, your lifetime, but thousands of years could pass on earth.\n\nIt has been theorized that time travel is posible but you could not simply accelerate to that speed.  Even if we could travel that fast the economical need would be currently beyond what any country has, even if they put all there funding into that one project.  but I am getting off the subject.\nOne theory is to travel into a black hole.  The gravetational field in a black hole is so strong that it has been theoryzed that even time cannot escape.  Thus if we were able to travel into a black hole we could use the captuered time there, so to speak, and transverse the timeline.\n\nThen there are ideas of actually traveling on light waves, lasers, to allow us to travel to the speeds necisary.  Of course then we could only travel to the time of how long that peice of machinery is on.  Also we would have to convert ourselvesinto an electrical signale, data (essicially transport), which would then bring up the promblum of measuring matter without moving it and blah blah blah.\n\nSummery, Yes it is possible to travel through time.  We just do not havet he knowledge and/or technology to do it yet.
