Question

Quizplus · Accepted Answer

Time dilation refers to the fact that time appears to stretch or slow down for objects that are moving at high speeds relative to an observer. This effect is predicted by the theory of relativity and has been observed experimentally. It means that time is not constant at all speeds and can appear to slow down as an object approaches the speed of light.
