fact if you are smart you would watch history are discovery channel ok Stephen hawking proved time travel by using the particle accelerator in Italy and France that if u are near a black hole and circle it that it well slow time and if you would travle at 99.9% the speed of light one day would = 2 years when you stop so what do you think
Time travel into the future has been proven and has been done on an infinitesimal level. Time travel into the past has yet to be proven and unfortunately we have no idea how to accomplish it, if it's even possible.
