Time travel into the future is definitely possible. Just freeze yourself and you're there. Another way is to jump on a spaceship that accelerates to the speed of light or close to it. When you come back, a lot of time will pass on earth while little time has passed for you. This effect even works for a ride on an airplane, you gain a couple of seconds or minutes. Clearly this is pretty easy and might be possible in the future.

Time travel into the past might not be possible. There really isn't any phenomenon known to be able to cause this. Some theories, like the multiverse, might suggest it might be possible and not cause a paradox. I'm sure you know about the time travel paradox but just to iriterate:

You travel back in time and meet your father when he was a teenager. You accidentally cause him to die. But doesn't that mean you were never born? But then if you were never born, how did you kill him in the first place?

In the multiverse model, The universe is just one possible path in an infinite number of paths. When you "time travel" into another universe, you can change things there without changing things in your own universe. But you would create another universe where you're never born. Still, even though there isn't a paradox, and even if there was a multiverse, it's not truely travel to the past and there's no definite way to do so. So I don't think time travel to the past is possible.

It's not whether it's possible. Time travel is a fact. There are atomic clocks on satelites that orbit the earth. They are transported forward in time by a few seconds every year. The question is can we come up with equipment and technology that can bend time and space. Most scientists agree that it would be impossible to get a spaceship to travel close enough to light speed to go forward in time.

So the next question would be, can we bend time and space. This is more likely, though right now there are no known technologies that can do it. Some fringe theorists claim that they can bend time and space directly in front of and behind a spacecraft.

Others say that by manipulating gravity waves through complicated physics they can manipulate time. Einstein and Tesla did do experiments that proved time travel. These tests were kept out of the media but if you do the research you'll find that some very unusual events took place at the same time that the atomic bomb was being invented. It is some very fascinating stuff that the numskull newspeople who actually work for the spinster government will not tell you about.

No, time travel is completely impossible.

First of all, there is no past or future, there is only now. The concept of time and a past and future are all human concepts. There is only causality, which gives the impression of time passing. Now the passage of time can be slowed, but not accelerated beyond its natural speed, and cannot be reversed.

Also, time travel violates the law of conservation of energy, which states that there is a fixed amount of energy/matter in a closed system (ie the universe) and energy/matter cannot be created or destroyed, it can only change form. So if you travelled in time, then there would be less energy where you left, and more where you went to.

Okay let's say you got around that by assuming the fixed system is 4-dimensional, and you have only "moved" along the temporal line (this is assumption is a fallacy, of course). Let's say you did find some way to send yourself back in time. Well, consider the fact that the earth is rotating and orbiting the sun, which is orbiting the center of our galaxy, which is currently in a gravitational dance with the other galaxies in our local group. Simply put, the earth will never be in the same position it is now. So if you travel to the past of future, you will find yourself somewhere in space or even in the center of the earth!

So it would take perfect calculations to move you in both space and time, at the same time. But in order to determine the actual direction and velocity of our earth, we must be able to measure it from outside this reference frame. Since we can't do that, there is no way to perfect the calculations to move you back to the location you were at relative to earth.

Imagine we could do that, though. Then there is the whole relative velocity issue. The direction the earth is travelling in space is constantly changing. Your velocity would not change. You would have to time it perfectly so that you didn't get smashed into the ground or fly into the air the instant you space-time travelled.

Also there are the space-time paradoxes that could occur like if you went back in time and prevented your parents from hooking up (and no, you wouldn't just slowly begin to fade out).

These are just *some* of the many issues we would have to deal with if time travel ever *could* become a reality. But it can't, so there's no reason to bother yourself with it.

Belive it or not researchers have theorised how time-travel would work however they don't know where to start with human teleportation.

Some theories, most notably special and general relativity, suggest that suitable geometries of spacetime, or specific types of motion in space, might allow time travel into the past and future if these geometries or motions are possible.

In technical papers physicists generally avoid the commonplace language of "moving" or "traveling" through time and instead discuss the possibility of closed timelike curves, which are worldlines that form closed loops in spacetime, allowing objects to return to their own past.

There are known to be solutions to the equations of general relativity that describe spacetimes which contain closed timelike curves, but the physical plausibility of these solutions is uncertain.

Everyone is a time traveler! We are all progressing toward the future from micro second to micro second! If time is discrete what is the interval between each discrete segment? The past continues to exist but whether anyone can access it will be amazing!

It has already been achieved.

The greatest time traveler so far is cosmonaut Sergei Avdeyev, who, by virtue of being on space flights for 748 days, is one-fiftieth of a second younger than if he had stayed home. So that man has traveled one-fiftieth of a second into the future.

the americans are already using a time machine device at maltulk point secret base.Unfortunanly they have not iron out the major problems with it yet.They can send people thought time but cannot get them back.

Well, anything is possible...but...here's another question...what would it take for you to try time travel? I'm sure alot of people didn't trust airplanes right from the start.

as we know time is passing by if we go back in the past

then what about the time that was in the present

in other words its not possible

No. I do not think it is possible.

Some things are impossible. It is just a matter of science.
