Theoretically speaking, if you were to travel at the speed of light, time would pratically freeze relative to you. What would happen if you traveled faster than the speed of light?

It's impossible.

I agree with you that speed is the key to time travel. Theoretically, if you go from point a to point b in 10 minutes, then go from point a to point b in 5 minutes, you have arrived at the same place sooner so you witness events that you would not have witnessed had you gotten there later. Light is the fastest thing that we know of, but really there is no limit to how fast something can go, we just haven't invented it yet. But using the theory/formula of increasing speed to witness and interact with events, eventually, speed would surpass distance and therefore arriving at a certain place would be relevant only to time.

I hope you dont expect a decent answer from Yahoo Answers :/
But heres' my take:
Travelling at the speed of light doesnt freeze time, it just gives the appearance that nothing is changing. But something is changing, your position (relative to the universe).
Moving faster than the light would simply put you ahead of the light, and while it might appear that things are moving in reverse, it's just the light that seems to be moving in reverse (relative to you).
Events themselves would not actually be reversed, only the light that lets you identify the event would appear to be in reverse. If you stopped, then you would see the events 'for the 2nd time', but the event itself only happened once, and you could not interfere with it.
In response to Mister El's answer (below), it will never be possible to go faster than light by simply increasing the speed.
According to Einstien's theory of relativity, as things move faster their relative mass increases. One of the conclusions of this, is that something moving at the speed of light has infinite mass!
And we know that moving larger objects takes more energy... moving even a tiny particle as fast as the speed of light, would take infinite energy! Nothing can possibly generate infinite energy... nothing that we pathetic humans can harness, anyways.

to do that you have to reverse the orbit of every thing in an orbit patern by staying in a curcler orbit around almost everything while sustaining an incalculable amount of speed

I dont know what would happen if we go back in time.
but i think traveling intime is impossible because there are a lot of paradoxes in that.

go to youtube and search for the elegant universe . Watch the whole two series and you will hgave some idea

You'd explode, but if you took a really fast plane, to a different time zone, you'd technically be going back in time, but then again there was that one time when superman spun the world backwards that he went back in time and punched a baby just to get away with it.

Hi. Time is like a river. You can step out of it (maybe) but not swim upstream against the flow.
