Introduction to general relativity - Wikipedia
Webe. General relativity is a theory of gravitation developed by Albert Einstein between 1907 and 1915. The theory of general relativity says that the observed gravitational effect between masses results from their warping of spacetime . By the beginning of the 20th century, Newton's law of universal gravitation had been accepted for more than two ...

WebEinstein came up with an explanation, his Theory of Special Relativity. He explained that certain things that we think are always the same, such as the length of an object, mass, and time, aren't really constant. They depend on how fast things are moving relative to each other. And in his Theory of General Relativity, he showed that gravity can ...
