WebJun 24, 2013 · This effect is known as "gravitational time dilation". It is predicted by Einstein's theory of General Relativity and has by verified multiple times by experiments. Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time.

WebAug 30, 2024 · $\begingroup$ General Relativity does not prohibit time loops in principle, but it does not explicitly allow time travel, as it would require physically impossible conditions. GR is a theory of a curved spacetime. Sure any such theory would allow you in principle to bend the spacetime in a loop. However this would require unphysical …
WebDec 11, 2003 · The constant speed of light demands a slowing of time, but in calling this effect "time dilation" instead of "time slowing," we obscure the influence of another element, possibly another constant that demands a stretching of the slowed-down time in order to maintain an absolute present.
