I do not believe there is anyone who can answer that question.
What do you think? your question is a wonderful starting point. Remember that less than 60 years ago most scientists were not sure if we could travel faster than sound waves, and one hundred years ago almost nobody believed that we could fly, and by then balloons and airships already existed!!!
Physics tell us that it can be done, so lets wait and see who can achieve it and how.

Sure. People do it all the.....time. We just time travel on such a small scale that it's not noticable. And only travel into the future is possible.
Everyone has heard the thought experiment related to Einstein's theory of relativity, where one of a pair of 30 year old twins takes off on a rocket and travels through space at speeds approaching the speed of light, while the other twin stays on earth. After a few days the space-traveling twin returns to earth to find that her twin has aged 50 years.
What happened? Well, Einstein showed that we all have individual clocks and that there is no universal time reference. In normal everyday life, everyone is moving slowly relative to each other. So any change in individual clocks is so small it's insignificant.
Can we demonstrate this in real life and not just in a thought experiment? Sure. We've taken a pair of the world's most accurate atomic clocks, synchonized down to the smallest increment possible. We put one on a plane in low orbit and left one on the ground. We flew the one in low orbit as fast as we could. When the plane landed the plane-clock was slightly (very small fractions or a second) behind the ground-clock. In other words, the plane-clock was "younger" and had traveled (albiet -very- slightly) into the the future, in relation to the ground-clock, to get to the present.

If it were possible, I think it would only be possible to travel to the future, not the past. That if time moves forward, which is what we experience to be true, then if we could move faster than that time, we could somehow end up in the future, but I don't think you could go back to where you came from, and I don't think you could travel to the past. If this were true, no one would ever know time travel really existed because they could never travel back to your time to tell you...that is assuming that they traveled quite a long ways.

Of course it is possible to travel in time. Matter of fact I would postulate that all travel is in time and of course this is proven by the algebraic formula t=r/d or time equals rate(speed) divided by the distance traveled. Which basically means any distance you travel would take an amount of time to cover it.
This is also proven by quatum theory and of course by Einstein's famous theory of relativity which states: E=mc2. Essentially energy (expended power or force) equals the mass (density or weight or proportion of an object) times the speed of light (c) squared. Which is another way of saying that crossing distance takes time that is measurable.
To explain this on a laymans level think about how you describe how far something is away from you. For example someone may ask how far is it from Seattle, WA to Bellingham WA. You might respond that Bellingham is about an hour and a half drive from Seattle. Or you might say it is about 90 miles from Seattle. But what you are really saying is that 90 miles equals 60mph times 1hour and 30 minutes. Which is of course the distance = rate/time or d=r/t equation.
I think the more interesting question would be: Is it possible to travel through or across time to the past or into the future. Matter of fact I'm gonna ask it myself.

In theory time travel is completely possible. If you really want to learn more about it you should learn more about String Theory and the other dimensions. For a starter check out the Flash movie at the link below.

This will be a good place to start.

Yes, it's really possible to travel in time, but not many people are able to do it and those people protect the knowledge of time travel, myself being one of them. Time travel is both interdimensional and dimensional and that's all that I'm going to say about it.

Space and time occupies the same dimension. However our present physical perception of time allows only a unidirectional dimension for time. It may be that there is multidimensional time but this is not currently a perception we can appreciate. Under the circumstances it is not possible to do time travel until we can find some other physics for this.

No you cant travel through time as in going from one time to another

As you sit in front of your computer reading this text displayed on your monitor, you are indeed traveling through time. We all are traveling through time at the same speed.

If you traveled at .99 the speed of light for one mouth, when you returned to Earth, it would be milenia in the future.
Traveling backwards in time is much harder.
