Time Travel

Time travel in reality is a mind boggling idea and seems utterly impossible.

Einstein's theory of relativity allows time travel in extreme circumstances. Some interpretations of quantum mechanics permit particles to travel backwards in time.

The speed of light is 67,000,000 miles an hour- nothing can go faster than the speed of light.

Time flows at different rates depending how fast you are going. So this means that if it were possible to travel very very fast lets say in a space ship. You could spend a year traveling extremely fast and come back to earth where a 100 years have passed on Earth. So you would age far slower than your friends back home.
