Well the current theory is if you go faster than the speed of light you would appear to go back in time. That is appear not actually go back but time would appear to reverse itself. (I think something to do with light moving in the opposite direction.)
My other question would be this...
you go back in time and the earth isn't in the same spot it was when you left. wouldn't you be stuck out in space or worse stuck in the middle of the planet? you have to remember that the earth revolves around the sun the sun revolves around the center of the milky way galaxy and this galaxy also moves away from universal central point. So when you take your jaunt back in time, space is different from where you left. Not only are you traveling through time you have to travel through space as well.
Imagine the calculations that would have to be made in order to jump through time?

Time is nothing but a measure of the changing of postions of objects in space.

Yes, time travel is entirely possible, even right at this moment. It doesn't need to be invented, it has always been possible.
