Actually, if I remmember well, some scientists have succeeded in sending information to the past. I don't have the links to do the research, but it was well documented by the press at that time. The experiment was something like sending some binary pulses from one place to another, which were receive before they were actually sent. I just read an article a few years ago and don't remmember the details.
Other experiments done at the PEAR labs, in Princeton University suggest the possibility of travelling information through time.
Anyway, for those who believe in reincarnation, the US scientist, Dr. Michael T. Newton did a research on the life between lives and wrote a series of books (The Journey of Souls) in which he relates a case of exploration of the past by the souls, not as in reading a book or seeing a movie, but by experiencing the subtle impressions left in the environment. If it is possible for a soul to have such an experience, it is certainly possible for a human being, who is an incarnating soul, but it is equally certain that it requires ability to have subtle experiences. If we think carefully, that's what the prophets have done throughout the ages (as well as some wise man in India, who wrote texts on ancient civilizations).
Now, if we can phisically go from one time to another, it has not been proved, but I don't see why it would not be possible. If it is, it certainly requires subtle abilities and a very refined phisiology.
Err..no they have not sent anything back in time. I think you are probably referring to Ron Mallet's proposals to build a time machine based on laser 'frame dragging'.
http://www.physorg.com/news63371210.html
The other possibility is that you are referring to the Nimtz experiment on photonic tunnelling..

Well, that depends on what you mean by "time travel", because you're travelling through time right now. You travelled through several milliseconds just reading the previous sentence. And then of course there is relativistic time dilation, where you can leap into the future relative to some other frame of reference.
i suppose you mean arbitrary travel through time - forward and backwards at will. If so, then so far science has proven time travel backwards is impossible in a few different ways - but that's all complicated quantum mechanics stuff. But of course "proven" does not mean the same thing in science that it does in mathematics or philosophy - so who knows whether it is really possible or not?
There are essentially two different theories as to what would happen if a time machine did exist.
The first is that if you were to go back in time and try to change the past... you would fail. Furthermore, any actions you made in the past would already be part of the past (whether you knew about it or not). In that kind of universe, if a time machine will ever be created, then time travellers from the future are already part of our history.
The second is that if you were to go back in time and try to change the past, you would create an alternate universe where your changes are now part of history. So if you went back to 1929, and killed Hitler, then came back to 2008, if you check the history books they will say "Hitler killed in 1929 by time traveller from 2008" (assuming you told them you were a time traveller from 2008). In that kind of universe, if you built a time machine and then went back and killed your past self an hour before you finished the time machine, you would now be in a universe where your time machine was not built... but you would still exist, and so would the time machine you travelled in, you would just have a hard time explaining where the time machine came from, and why you are standing next to your own corpse. | Zuex wrote: |

Well time travel into the future is possible, in a way, if you go on the speed of light then time for you might seem normal while... infact it goes slower for you. You are traveling into the future.

There is also the 'Many Worlds' version. In this version the act of going back in time would project you into a new 'universe' so there would be no paradox since what had already happened would be in a separate spacetime reality...
(It's a bit fanciful for my tastes)

Reading what you've wrote makes quite abit of sense, that even going back in time and trying to change the past won't work, because it is already from the past etc etc, what everyone is posting is very interesting.I think that the best proof to deny the possibility of time travel (backwards at least) is that there is nobody who has built one in the future and travelled back. Cos if they did we'd know about it. Human nature is such that eventually someone greedy/maliscious/evil would travel back in time and try and take over the world. Even though someone later might try and correct it the nature of humans means that there will always be someone worse in the future and they will keep trying.
Just try to imagine a scenario that from the minute a time machine was invented to the end of the universe, not one single solitary bad person had had access to the time machine - we can't do it with nuclear weapons over a time span of 50 years so we certainly would not be able to with time travel over eternity!
However, I suppose that the Many Worlds scenario could still exist - all the meddling has happened in the parallel universes and we are in the one that is unaffected (by complete random chance) although in a second some of you will 'shift' into a different parallel universe from me and leave a copy of yourself - or something (gets slightly confusing).

The only 'scientific' explanation I've ever heard about a time difference is what occurs over great distances which could be achieved by traveling at near speed of light. It is not an actual time change but something to due with relativity. Like traveling in space and coming back to find that everyone has aged more than you or something like that.
Time travel is a great what if paradox though and great for SCI fi novels.
In my opinion even if time travel is possible it is a bad idea. Who know what the effects could be.
And with what some other people have said i have heard of experiments where particles have been sent at extremely high speeds through a tunnel and actually appeared a fraction of a second before they were sent through.

One would think that if any time traveller understood time well enough to be able to travel around freely within it, they would know the consequences of doing so. Just because we are ignorant of the possible effects, it doesn't follow that someone who could do it would be.

No, those claims are based on misunderstandings of the physics involved. A single particle - for example, a photon - has several different speeds, depending on how you measure it. Various experiments have changed the phase velocity of photons or the group velocity of photons to several times c (the speed of light)... but none have actually changed the signal velocity of photons - the signal velocity is always c. In simplistic practical terms, it's like cheating - if you want to time how long it takes for Joe to run from one office to another down the hall, and you know that he is on his way and no one else is around, you can hit the "stop" button the moment you hear someone outside of the finish line's office door. The problem is, if you don't know that Joe is coming, you don't know when you hear someone outside whether they are actually coming in or not, you certainly don't know that it's Joe. To cheat, you need to have the information about the photon beforehand (and that information will be limited by c). Without it, you don't know that you are receiving a photon at all (and by the time you do, it will have been limited by c).
Despite what many people claim, there are many, many things in our universe that travel faster than light. The problem is that we cannot use those mechanisms to transmit information. If we could, we could (at least) send messages to the past (and possibly travel ourselves). But we can't. | powers1983 wrote: |

I do agree that humans are indeed greedy but maybe in the future we will invent an AI and put it in charge of it. That will eliminate human greed and restrict acces to it for anyone. Just tell it to explore the whole past and then come back to exactly 1 millisecond from when it left. But again this is whole speculative however it can be a good SF story.

Well if we learned to time travel. We could find out some mysteries, just make some micro camera's that look like fly's and monitor what happened in the past so we can answer some questions like:
Who killed kennedy? How did the egyptians build the piramids? What happened throughout history? We could answer all questions and remove all doubt's.
But such questions are maybe not very important. We also would answer questions as:
Where do we come from is evolution real? And then look at our own development we would be able to solve the questions of the universe how did the earth came into existance? The moon the sun we have scientific theories now but we still don't know for shure.
If we were able to time travel and make shure no one would abuse it, we would get a whole wealth of imformation in a blink of an eye.Hmm...I don't think it's going to happen because if it was, something from the future should already be in our time. Theoretically, everything should have been in chaos right at the beginning point of 'time' if a time machine were possible.

If there is an time machine being build in the future it doesn't automatically mean that we would know it, they can make shure we don't notice it.If there was a time machine, that means matter would be changed every time someone used it and theoretically, that's impossible.
Also, how would you explain something?

No he didn't. Special relativity shows that travel IN SPACETIME is limited to light-speed. General Relativity, however, allows for 'frame dragging' where spacetime itself is 'moved' relative to the surrounding spacetime.i thought of it and i get that bound to make a time mechin or travel in the time i cant say why in english i can only in hebrow sorry

Excellent Post....actually made me Laugh Out Loud.... I don't think this would be possible.
What has happend in the past, is not gone. I do not think there is any way of re-creating of what has happend. Where are where we are now, there is no going back.
Now traveling with teleporting to like another galaxy would be more understanding. But time travel? Doesn't seem possible...
As a kid i always dreamed of owning or inventing the time machine but now i believe that this would be quite impossible. i think everything about a time machine is impossible but certain elements of time travel possible. I don't believe that this could be achieved with stability or choice of when or where to travel but I do believe that time travel is possible. I'm not going to say that a time machine is completely impossible because anything is possible! but its unlikely
i hope my views have been understood

I like where you're going with this, but consider this: What if Bill Gates was a time traveller?
Maybe he became the most successful and rich with technology because he stole it from the future.
What if Hitler was from the future because German engineering went through some advances, and he also had some excellent ideas when it came to gaining power in Germany legally.
I mean, it's unlikely, but we have to give time travellers (if they have existed) the benefit of the doubt that they would be able to not leave too much of a trail.
And while we're at this... what if Jesus was a time traveller? That'd certainly explain the miracles and such if he had some crazy 25th Century technology. | Zuex wrote: |

The interesting thing about time travel/machines is that if it were possible in the future, that would mean that there would already be people from the future here.
BTW, there is a movie from the 80's called "Back to the Future" about this very thing.

Oh looks like somebody had the similar idea as me. Come to think about it, didn't he just "disappear"? I mean, isn't it just speculation that he moved to Argentina or committed suicide? Was his body ever found?

Just out of curiosity... why does everyone immediately jump to the conclusion that any change to the past will result is "damage"? If we went back in time and gave modern technology to the people in the past, especially medicine and technologies that increase food supply and so on, won't that mean more people will live, not die? And... given that they don't need to invent those things themselves, won't they have more time to invent other things, like space flight and so on, so that our current problems of overpopulation and environmental disaster won't even have happened?
| Lord Klorel wrote: |

Wouldn't the future people have a problem with you using future knowledge to "damage" their past? ^_^;A new concept for a time machine could possibly enable distant future generations to travel into the past, research now suggests.
Unlike past ideas for time machines, this new concept does not require exotic, theoretical forms of matter. Still, this new idea requires technology far more advanced than anything existing today, and major questions remain as to whether any time machine would ever prove stable enough to enable actual travel back in time.
Time machine researchers often investigate gravity, which essentially arises when matter bends space and time. Time travel research is based on bending space-time so far that time lines actually turn back on themselves to form a loop, technically known as a "closed time-like curve."
"We know that bending does happen all the time, but we want the bending to be strong enough and to take a special form where the lines of time make closed loops," said theoretical physicist Amos Ori at the Technion-Israel Institute of Technology in Haifa. "We are trying to find out if it is possible to manipulate space-time to develop in such a way.
In my opnion, in every second we are transacting with lots of energy in different forms,
if you want go back in time, you need to supply/ or should have a ready backup of
supply of all such energies in very small time
It is theoretically possible to travel forward in time, but traveling back in time is a lot harder.
Traveling forwards is possible when you gain a high speed, very close to the speed of light. If you travel at or close to the speed of light the time in the universe around you will go quicker than your own time, so when you stop traveling on such a high speed, the universe around you got older than you did. This has been tested with a highly accurate clock(I don't know how to call them in English 
). That clock traveled around the world at a very high speed and after a while the clock was running a very tiny bit behind. I don't know the exact time. Not quite right.
Your own time is always constant for you. When you travel fast, relative to a fixed point, then your own time is different (slower) to the time at that point. As far as you are concerned time passes normally. As far as an observer at the point is concerned time passes normally. When you eventually came back together, however, you would find that your time was different to the time at the point. If you travelled very fast indeed then you might have aged by a year, whereas observers at the point might have aged a decade, for example.
There is no 'universal' clock - each frame of reference has its own.
Interesting repsonses everyone. I've always had a point of view as per time travel and it relates closesly to a theory I've founded about death and the nonexistant. If you simply utilize the Conservation of Energy law and alternate realties/parallel universes aside, every chemical action to ever occur in your body or on this earth remains in some other form of chemical composition. From the death point of view, every memory a person has ever created or "thought" never disappears but rather over time is used and reused or dispersed somewhere else. Thus, for every mental task the deceased person has ever done (memories, correct?) some remnant of that still remains whether it be within different action potentials or as entirely different purposes.
Applying this to human existance and time, the only remnant of time is chemical composition. For every car ever started for example, a byproduct is released through heat and carbon monoxide. Looking at this through my theory, every vehicle ever started in the history of the universe has left a trace no matter how far reaching it might be. Consequently, time does leave a permanent remnant in that it is transitional.
So for a time machine, we would have to capably understand all forms of physics and quantam physics in the unvierse (for the automobile exhaust, I.E. the weather patterns to an exact science...trace their flow from the beginning of their leaving the exhaust, but that is of course, an obvious physical remnant where as things like emotion would have to be decoded). I would imagine, if done possibly, time would represent a three dimensional fluid movement of mass and chemical reaction, somewhat similar to how chaos theory represents a chaotic map. Thus, we could never TRAVEL back in time as per an actual human, but rather look back at time through a virtual re-reprensentation of the universe's' existence.
Let me explain why a time travel is impossible.
Opinion supporting time traveling
It's said that a time machine would be invent because an airplane was invented to help us go up or down. Before a plane was invented, we can't fly up, just walk forward or backward, turn left or turn right. So, why can't we expect a time machine will be invented to help us travel across the time?
My Opposite Opinion
That's the problem!! When we are on a plane, we didn't leave vertical dimension at all, even we can move freely in it. Therefore, if a time machine was invented, we could travel across the time. But REMEMBER, we can't leave the time, we will be younger or older on the so-called time machine. How about 100 years later?? Maybe you just make yourself dead faster. I can't see any point in inventing such a machine, which will never be invented.

This is based on a misconception about space and time (spacetime). Time is relative to the observer as is length (and mass). There is no 'universal' dimension in which you move - each person moves through the time dimension at a different pace, depending on their relative speeds. Your clock will always tick (to you) normally, unless you exceed the speed of light, somehow, in which case all bets are off. | Bikerman wrote: |

I mean even though time can be controlled, we need to be out of the control of time. | takashiro wrote: |

Nope - I don't understand that at all.dude come on einstein disproved time travel
ANYTHING IS POSSIBLE
People thought we couldnt land on the moon. Never doubt the power of science and technology.
Time travel is already technically possible ie Newtonian Relativity which is traveling at the speed of light. Its been confirmed and tested. Who knows what else is possible.

Newton had nothing to say about time travel. Newton based his work on Galilean relativity which shows that speed is relative, but assumes that time is invariant. I think you mean Einsteinean Relativity (specifically Special Relativity).
There is a difference between 'people' thinking we could not land on the moon and a scientific theory which says the speed of light is a limit.
Clearly not all people thought we could not land on the moon - have you read HG Wells - The First Men in the Moon (1901)?I also don't think it is created because you would need to have a machine right now to travel from the future to now. No machine = No travel. It is possible that we might create a machine in the future and as soon aswe create it, people will start walking through it from the future.
How should a timemachine work ?
Well, i don' believe time travel is possible in anyway, because whats done is done.
Say we could though, then there would be a person living an instant for eternity, because why would people be there when you went back? If you went back a little further, they have to be there again? So there would have to be millions of copies of people to play every instant in the past. If not, then it would be more like traveling back to a memory that just plays when you get there, and you won't be able to interact with them at all.
