Ready to travel through time? Here are a few things to keep in mind. When you move faster in space, you move slower in time. You are actually aging more slowly when you're in motion than when
you are standing still. (In fact, Einstein might still be alive today if he had jumped on a spaceship traveling near the speed of light.)
How can you tell when time is moving more slowly? You can't tell unless you move
close to the speed of light, and then compare your watch to that of somebody who had stayed behind.
Sound too wild to be true? Scientists have actually
confirmed this by placing very accurate clocks on flying airplanes.
Here are three ways to do it:
Sit there. Okay! You've just traveled through time!
Run for 2 minutes at full speed. Just by staying in motion that long, you've aged a
tiny bit of a second less than a person who is standing still!
Travel on a plane going about 600 mph for your entire life. You'd age more slowly than
your friend who is sitting at home, but only by a fraction of a second and you'd have to eat a lot of airplane food!
