Can gravity slow light
WebGravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events as measured by observers situated at varying distances from a gravitating mass.The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational potential increases … WebDec 9, 2024 · However General Relativity can predict how light will bend when it passes through a strong gravitational field. We say that the world line of light is a "null geodesic" in four dimensional spacetime See Why is light described by a null geodesic. Light can't escape a black hole, because all the null geodesics in a black hole end on the singularity.

WebSep 12, 2024 · This is what happens to light traveling through space: When it comes too close to a massive object, it encounters warped space-time and curves not because it’s being pulled by gravity, but ... WebFeb 12, 2016 · No, gravitational waves also travel at the speed of light in vacuum. However, the interstellar medium is not perfectly empty but filled with plasmas which slow electromagnetic waves (light, radio) down by a factor n, the refractive index. The slowing occurs because the photons are absorbed and reemitted, which takes some time.
WebSep 23, 2010 · Gravity isn't the only thing that can warp time. According to another one of Einstein's theories, special relativity, time slows down for an object when it moves. A twin launched into space on a ship traveling near the speed of light would find on his return that he had aged more slowly than his brother left at the surface. WebFeb 9, 2024 · You know you can’t reach the speed of light for a massive object, so the naive thought that “50% the speed of light + 50% the speed of light = 100% the speed of light” has to be wrong.
