Time Travel
The Twins Paradox uses Einstein's Theory of Special Relativity to explain that time travel is possible. Let's say two twins are on Earth. They are both twenty years old. One leaves in a spaceship. She is gone for sixty years. When she returns the twin that remained on Earth is eighty years old, she on the other hand appears to be about thirty. How did this happen? Her spaceship must have been traveling at or above the speed of light. When traveling at the speed of light time slows down. It doesn't really slow down (to you the person in the spaceship) time to the people on Earth seem to speed up. It is impossible to travel back in time, but if a human can travel fast enough they can bend time enough to not age as fast relative to humans on Earth.
