We already can travel to the future. The faster you move through space, the slower time moves for you. So astronauts have travelled a few nanoseconds into the future because they travel so fast orbiting the earth or going to the moon. Travelling back in time is another issue. Supposedly time reverses when moving faster than the speed of light, but we don't how to do that.
