Regarding everybody who is saying that this kind of thing will probably only be possible in hundreds of thousands of years, remember that the rate of technological development is accelerating constantly so you never know what could happen in just 200 hundred years.
Another thing I need to make clear is that time travel to me means experiencing the passage of time differently from the rest of the human race. For example if you travel close to the speed of light you can travel for hundreds of someone else's "years" in a matter of seconds.
However as this is proven to be possible what i really mean is the ability to experience time backwards and then forwards again and then find yourself at a time before you started off.
