Time travel

Time travel is no bullshit, it is theoretically possible but it is still impossible with current technologies. In order to time-travel, we'll need to travel at speed of light or ( exceed the speed of light,c). Maybe the government intends to keep it a secret so that there is no misuse of time machine in the future. John Titor, who claims he is a time traveler from year 2036. Some of his predictions are accurate, but still, it sounds illogical for us to believe that, maybe it makes more sense if he comes from a few hundred years ahead. As far as we know, the current technologies that we have are still incapable. Anyway, I think John Titor's stories are just internet hoax. But, still, there is a possibility that he exposed his identity to the people, he wanted the people to believe in time travel. All these are just assumptions. Who knows.
