This is a tricky subject. As was already stated, we are traveling through time at a nearly constant rate already, always going forward. However, it has been proven that when we move faster in physical space, we also move slower through time. There was an experiment testing Einstein's theory of general relativity that took two clocks set exactly to each other down to the nanosecond, left one on the ground and took the other on a very fast jet, and by the time the experiment was finished, the clock that had been on the jet was one nanosecond slower than the one on the ground. Another theory that takes inference from Einstein's theory of general relativity states that when you surpass the speed of light, you start moving backwards in time. Using this theory, you could say we've already created a method of time travel. Some scientists have been able to accelerate photons to 5 times the normal speed of light. How they figured out they'd done it, I'll probably never be able to figure out, but it means that it should be theoretically possible to use this photonic acceleration method to accelerate matter as well, which would theoretically push us backwards in time. This is all very theoretical, as you can see, and some theories actually seem to prove that accelerating past the speed of light is impossible for massive objects, as they actually gain mass as they approach the speed of light, becoming infinitely massive as they move infinitely close to light-speed. However, this would seem to say that black holes are moving infinitely close to the speed of light, and we just don't know about that yet, they seem to us right now to be moving at normal speed. So there's a lot of debate in the issue. The simplest answer is that we are moving through time, and we can control that movement to a small degree. However, we just don't know when we'll be able to substantially control our temporal passage.

I'm my own grandfather as the result of an accident with a condom and a time machine. (Apologies to Mr. Adams, or someone.)
You are traveling in time at the astonishing rate of an hour every hour.
But is time quantised? Is there a period of time which is the shortest possible and all other periods are made up of multiple bits of time quanta? If so, can we call it a "chronon"? What is it's wave function? Is it the same as the Planck time, 10^-49 seconds? Or is it shorter? Why am I writing this guff? Two lousy points is all I get.

Time travel is impossible. For a start we are moving through space at an incredible speed already. If you went back in time by 1 minute, without taking into account this distance travelled by the Earth and solar system around the galactic centre, then you would find yourself in empty space.

Well to go forward in time seems imposable because that means that every ones life and every move is predetermined and i don't believe that. Now to the past could happen in a since. for example the light you see from the stars took years to get here and there for makes it light given off in the past. If we could travel faster than the speed of light that we could go to the past. Here in lies the problem it would be the past, of the light you move towards, only to you but time will still move as fast as ever and if it took you a year to get there and back it would be a year later here too so it probably will never happen.

Time travel is not and never will be possible.
If it could happen it would be a common practice in all eras now included.
Ken e is right about the quantum time, it is the principal that limits the speed of light.
In any sci-fi concept of time travel exceeding the speed of light would be necessary.

i do not think there will ever be an age were u can travel backwards in time... however, it is possible to travel forward in time... for example if i were able to travel through speave at the speed of light, like a second could tick by on my watch but back on earth like 100 years could pass... This is the E=Mc2 theory of eiensteins and i get how it works... but thats a realy long conversation to explain = P ... i dunno.. think about it...

If you were researching on it for a long time as you say, you wouldn't ask that question.
We simply do not know when it will be possible, we do not even know, whether it will be possible after all. And for we don't know nothing related to that, no estimation about "when" is possible.

You see things in front of you. You dont see things behind you.
You see the past. You dont see the future.
We are going backwards thru time already.
Good luck unraveling that. :-)

Once time travel is invented, you can go back in time and invent it again. So then how can you ever tell when it was invented?
