Gravitational time dilation is related to the curvature of spacetime caused by mass and energy, while time dilation due to acceleration (known as "kinematic time dilation") arises from the effects of relative motion and the constant speed of light.

2019年10月26日 · It might help to see what's going on, if you know where that equation came from. That expression for gravitational time dilation comes from the Schwarzschild solution to Einstein's field equations from General Relativity. The Schwarzschild metric tell us about the space-time in a vacuum near a stationary, spherically symmetric mass. That it's a ...

2021年10月26日 · Gravitational time dilation is an actual objective effect, unlike the apparent subjective time dilation of special relativity. Observers who are stationary with respect to each other (in space) but at different “heights” in a gravitational field will agree that time runs at different rates in each of their localities, and the observer for ...

2019年10月18日 · The gravitational time dilation is related to the gravitational potential, not the gravitational acceleration. In the center of a planet the time dilation is the largest even thought the gravitational acceleration is zero.

Gravitational time dilation caused by a galaxy, and by. 5. Voyager local time dilation (caused by gravity ...

Gravitational time dilation can't be fundamental because the gravitational potential isn't even well defined unless the spacetime is static. For example, cosmological spacetimes aren't static. A good popular-level book that explains the fundamental status of the metric very clearly is Geroch, General Relativity from A to B.

2020年5月20日 · But technically there is a tiny, non-zero time dilation effect. For astrophysical sources like LIGO has detected, this time dilation is very much suppressed compared to the already tiny spacial stretching. I personally think of the near field longitudinal modes as "time varying gravitational potential" not "gravitational radiation".

2018年4月5日 · "Gravitational time dilation" and "velocity time dilation" aren't in general clearly separable, physically distinct phenomena. All time dilation is due to the relative velocity between two inertial frames of reference. In a curved spacetime, it isn't possible to define an inertial frame of reference that covers all of spacetime; instead, an ...

2015年10月29日 · Are gravitational time dilation and the time dilation in special relativity independent? Related. 5.

2022年12月21日 · $\begingroup$ As JEB, Yukterez, and Kevin mention, the time dilation due to the Sun's GPE (gravitational potential energy) is much larger than that due to the planets' GPE. $\endgroup$ – PM 2Ring Commented Dec 22, 2022 at 16:47
