The Theory of Relativity

Einstein's special relativity shows that time passes slower for objects moving at high speeds (time dilation), and mass increases as objects approach light speed. General relativity explains gravity as the curvature of spacetime caused by mass. GPS satellites must account for both effects to work accurately.

Because of relativity, GPS satellites' clocks run 38 microseconds fast per day!
