Time is space. You can't go backwards only forward. The only way to go forward is to travel faster then the object you want to see in the future. This is why astronauts in space currently are a few seconds younger then us. In fact there very complex equations in satellites that have to account for the time difference. It's also why we can point telescopes at the center of the universe and see near the beginning since space is expanding, pushing us faster then the speed of light. If a person were to some how travel near the speed of light for a few months and come back to Earth hundreds of years would have passed even if it was only a few months for him. Hence why we can never go into the past, only the future.
