Time dilation - Wikipedia
Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity, a consequence of special relativity, or a difference in gravitational potential between their …
Time dilation | Definition, Equation, Examples, & Facts | Britannica
Jan 8, 2026 · Time dilation, in special relativity, the ‘slowing down’ of a clock as seen by an observer in relative motion with respect to that clock.
5.4: Time Dilation - Physics LibreTexts
Mar 16, 2025 · Time dilation is the lengthening of the time interval between two events for an observer in an inertial frame that is moving with respect to the rest frame of the events (in which the events occur …
Understanding Time Dilation: Why Time Moves Differently in Space
May 23, 2025 · This idea, that time is not fixed, is not just the stuff of science fiction—it’s a scientifically validated phenomenon known as time dilation. Popularized by Albert Einstein’s theories of relativity, …

Einstein Showed That Time Is Relative. But … Why Is It? - WIRED
Jul 18, 2025 · The mind-bending concept of time dilation results from a seemingly harmless assumption—that the speed of light is the same for all observers.
Time Dilation and Length Contraction | Principles & Implications
Time dilation refers to the phenomenon where time passes at different rates for observers in relative motion. According to special relativity, a moving clock ticks slower compared to a stationary one.
