Einstein's theory of relativity establishes that time dilation occurs for particles moving at high speeds, causing them to decay more slowly than expected. This phenomenon has been verified through experiments, including the behavior of atomic clocks in GPS satellites and the decay rates of muons. The constancy of the speed of light for all observers is a fundamental principle that leads to the distortion of time measurements across different reference frames. Understanding this concept is crucial for grasping the implications of special and general relativity.
PREREQUISITESPhysicists, students of relativity, engineers working with GPS technology, and anyone interested in the fundamental principles of time and motion in physics.

Yes. I tend to speak a little fast and loose because there is no good pithy term for the force-per-unit-mass.Mister T said:That's the gravitational field, the force is ##mg##.
