still its a question .
But according to Einstein "theory of relativity" time travel is possible
when a person's motion is very fast according to him time moves somewhat slowly.
this was already proved by Einstein.
so may be time travel would be possible in future.
hope this answer helps u....

Avanish010: bro..time machine will not b made ever...

Time travel has always been one of the most fascinating things in science. And as it turns out, we have the complete knowhow of traveling into the future.

It all started when Albert Einstein brought forward his Special and General Theory of a Relativity.

He suggested that 'time' is not absolute. It is a relative concept like motion. In other words, the reference of time for each independent observer is different.

In the Special Theory of Relativity, Einstein showed that The Speed of Light in vacuum (which is 299792458 m/s) is the only constant thing in the universe.

Einstein gave the time dilation equation, which suggests that as we move faster and near the speed of light, time must slow down for us.

This means that if you are in space moving at near the speed of light, then for every T seconds you experience, the people at Earth will experience greater than T seconds.

Example: you feel that only 1 year has passed for you, but for people at Earth, 3 years have passed by.

In this way, you are traveling into the future.

In the General Theory of Relativity, Einstein gave other equations showing how time is affected by the presence of mass in space-time.

The more massive an object is, the more slowly time will flow near it.
(Actually, the correct term is density. So the more dense an object is, the slower time will flow near it).

This happens because massive objects create a distortion in space -time, and so light follows a curved (and longer ) path. As speed is light is constant, time must slow down to cancel the effect.

The extreme case is black hole, where it's density tends to infinity at its centre (this is called a singularity).
So, time literally stops inside a black hole.

These ways tell us about going to the future.

But what about the past? There is only one way we currently know of: Traveling at a speed faster than the speed of light in vacuum.

But since General Theory of Relativity doesn't allow that, we don't know any complete foolproof plan yet.

However, the conclusion is that time-travel into future is indeed possible, when we have the right technology to develop equipment for that.
