I think it's quite possible, it's just a matter of time before we manage to create such machines. It's like teleportation, who would say it's possible? But our current technology has developed to a level where scientists managed to create a device which can actually transport small things, in their sub-molecular state, through a short vacuum tube and successfully reassemble it on the other side. This was performed with a pencil using a 1m length tube.

Where did you read about this Zyd ? Link me

I can't give you the link to this precise experiment, but if I find it, I'll make sure to share it.

I think i read something about an object being at two places at the same time which is something my little brain cannot understand (which doesn't mean it's not possible) but I can't remember if it actually was something that was done or just a theory.

I think eventually it will be possible- but will be outlawed just like cloning is.

plus it will probably be something complicated like a black hole, when you can't get back anyway lol

I've read somewhere that time is an infinite loop (fashion loops, why not time). In theory it is possible to jump forward or backward in time (time being a never ending loop), however the power source needed to generate the energy required for a time jump is so large that it doesn't currently exist. So time travel is still just a dream or theory.

Characters in sci-fi's time jump (Quantum Leap, Star Trek) and some of yesterday's (yesterday meaning past/old) sci-fi has become sci-fact, so why not time travel too!

I believe in order to do that they would have to create a praticle accelerator so big that it should be build in space.

This is an interesting subject...

In the conventional sense, is time travel possible? No. You aren't going to hop in your delorean, punch it to 88mph, and go back in time, all made possible by your flux capacitor. Then, there's the however...

However, time travel, as covered by a couple others here, in a different aspect, might be possible. Since time is relative, if you were to approach the speed of light, since itme is relative to the person observing the passage of time. For them, time would pass slower, and when returning to time moving at a speed at which it would when standing still, the person would appear to have traveled forward in time. IE; everyone else advanced days/weeks/months/years, while said person only saw the passage of fractions of a second, depending on the extreme. In this sense, it is only possible to go forward in time, not backward.

However, there is then theory two... In this theory, you can bend time, so to say, and jump to a different point in time. However, this will never happen, because here we are. If that was done, the "ripple effect" would begin destroying time both forward and backward on the time line. This would be virtually instant, as it would operate outside of time. And we'd all go poof.

Then, there's theory three. This one is good, too... We don't exist. Since time, by definition, extends infinantly in all directions, as well as space, infinantly in all directions, they are said to be unlimited. Now, we're going to stop there, and break that down to two different theories.

Sub-Thoery one. Nothing can be infinite, yet the universe and time cannot be infinite. Thus, we exist in a space/time which cannot exist, thus we don't exist. So why are we here? Momentum. Haven't come to a solid conclusion yet, but the data has not yet presented itself. Eventually the momentum will cease, and we'll end up once again with nothingness. It's a bit more complex than that, but that's the general gist of it.

Sub-Theory two. Since we don't exist, anything is possible, through the use of momentum. Movement through time, unaided flight, mind bullets. It's nothing more than a matter of figuring out how to manipulate that which is around you. Remember, we don't exist. You think that's air your breathing? ;) Go back, and win a major sporting event of some sort, now that you know you can. Remember, we don't exist, we are not bound to physics, we just think we are.

It's impossible. 'cause if you go to the past the history will change and future will change too.

Watch the video I posted before, you can only travel as far back in time at the moment the first time machine was created.

Maybe is possible, but not till the time my grandchildren die, and i guess even if it is possible people will mess up with it, like they did with the flying thing. They build Planes to throw bombs.They can fly to moon, but the same technology can kill thousands of people in a sec. I hope they never can travel in time, because they will build a weapon and kill million of people.

Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. 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.

Newton'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."


Albert Einstein, whose theories of relativity changed our understanding of time and space, once wrote "Newton, forgive me."
--------------------------------------------------------------------------------

Einstein'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.")
Is 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.

Honestly i think its impossible.

If you've watched the movie deja vu, they explain to you that every time you travel back in time you get a diffirent time paradox which makes 2 new time lines, one from which you came, and one that is in the paradox you are in now. its a little complicated, but it does make sense.

if we could time travel? it's either when we get wormhole technology, or by useing massive speed.

what can we say about it, maybe, nothing is impossible.
as you know black holes suck up light, matery and anti matery, even time.
so what would happen if you reverse that effect. anything is possible, as long as we have the technology and the resources to do so

I thinkkkk, of course is possible but i can't do, the time is just like a secuence of instants ( an instant it's the lower intervale of change of state from some object) sou if someone could do balckholes or worm tube(some stuff like that) can travel, i recommend read the books of Stephen Hawkins
