Time dilation is a phenomenon predicted by the theory of relativity, which applies to all objects, including nonliving things. According to the theory, the passage of time can be affected by the relative motion between two observers or the strength of the gravitational field they are in.
For example, in special relativity, time dilation occurs when an object moves relative to an observer. As the object's velocity approaches the speed of light, time appears to slow down from the perspective of the observer. This effect has been experimentally confirmed in various experiments, such as with atomic clocks on fast-moving objects like airplanes or satellites.
In general relativity, time dilation can also occur due to gravitational fields. Clocks in stronger gravitational fields run slower compared to clocks in weaker fields. This has been observed in experiments as well, such as with atomic clocks placed at different elevations where gravitational fields differ.
Therefore, both motion and gravity can affect the passage of time for all objects, including nonliving things. However, the observable effects of time dilation are typically more pronounced at extreme velocities or in strong gravitational fields. For everyday objects and ordinary speeds, the differences in time dilation are negligible and not noticeable.
