time dilation
Physics term for the relativistic effect where time passes at different rates for observers in different frames of reference.
When moving at speeds close to the speed of light, time dilation occurs.
GPS衛星では、一般相対性理論による時間の遅れを補正している。
GPS satellites correct for time dilation due to general relativity.
Compound of 時間 (time) + の (possessive particle) + 遅れ (delay, lag). The term is a direct translation of the English 'time dilation' used in physics.
