time dilation

noun

1. the principle predicted by relativity that time intervals between events in a system have larger values measured by an observer moving with respect to the system than those measured by an observer at rest with respect to it

time dilation

1. The relativistic effect of the slowing of a clock with respect to an observer. In Special Relativity, a clock moving with respect to an observer appears to run more slowly than to an observer moving with the clock. In General Relativity, time dilation is also caused by gravity; clocks on the earth's surface, for example, run more slowly than clocks at high altitudes, where gravitational forces are weaker.

time dilation

1. In physics , the apparent slowing down of moving clocks that is predicted by the special theory of relativity . Time dilation is well verified experimentally.

Example Sentences

High-energy muons traveling at near–light-speed endure longer, for milliseconds, because of the time dilation predicted by Einstein’s theory of relativity.

From Science Magazine

Since the wave experiences a time that is different from the laboratory time, the researchers found that accelerating waves also experience time dilation and length contraction.

From Science Daily

This approach minimized the chance of making “apples-to-oranges” comparisons between distinctly different quasar types and allowed the researchers to calibrate each quasar’s “ticks,” yielding more certainty that some of the observed discrepancies in light fluctuations were caused by time dilation.

From Scientific American

Specifically, the study confirms that quasars align with consensus expectations—and it reinforces the need for astronomers to consider time dilation when studying them.

From Scientific American

Quasars found in faraway galaxies ticked slower than ones born in the later, nearby universe, with time dilation making those most distant appear to run at a glacial one fifth of the standard speed.
