Cool Speed Of Light Vs Speed Of Vravity 2023. Web this case is sometimes called special relativistic time dilation. Web the speed of light is constant, so if light is passing through this gravitational field, it does not slow down but rather time itself relative to the observer, slows down.
Web the special theory of relativity is really enough to see that gravitational signals have to propagate by the speed c c which we call speed of light because the light is the most commonly understood entity that is moving by this maximum speed. Or, to be more precise, gravity moves at 299,792,458 metres per second, a rate we can just call c. Because, in einstein’s theory of gravity (general relativity), nothing can travel faster than the speed of light.
