Physics Logic

According to Einstein's special relativity, as an object's velocity approaches the speed of light ($c$), time for that object slowing down relative to a stationary observer. This is not an illusion, but a fundamental property of spacetime.

About Relativity Time Dilation

Experience the physics of the very fast. Calculate the time dilation between a moving observer and a stationary one using the Lorentz factor ($ gamma $), with visual context for speeds approaching $c$.
