Physics in a Minute: The twin paradox

Twins can be competitive, but thanks to special relativity you could age slower than your sibling. The feat requires a trip to space aboard a rocket travelling near the speed of light. Known as the twin paradox, this animation by The Open University explores the scenario posed by Albert Einstein.
As time marches on as usual for the earthbound twin, time ticks slower for the space explorer thanks to the time dilation of relativity. The faster you travel through space, the slower time passes.
