Time Travel: Into The Future

Physics has many ways of explaining the idea of time travel into the future, one of these ways is travel using a craft that could move at speeds faster than light. According to Einstein’s theory of relativity, as an object reaches and goes beyond the speed of light time is slowed. Say the object was a spaceship with a person onboard, while traveling at light speed time appears to be moving fluidly, but in truth, time has a slowed around the person. Therefore, while the pilot has been traveling for a particular amount of time, for everyone else much more time has passed. For example, an hour for him may be several years for us, in effect, he has traveled through time (“Time Travel: Einstein,” 2007). In this method of time travel, travel into the past is also possible although not as easily explainable.
This is explained more thoroughly in this TLC documentary clip found on youtube:
