Relativity, wide-ranging physical theories formed by the German-born physicist Albert Einstein. Special relativity is limited to objects that are moving with respect to inertial frames of reference. General relativity is concerned with gravity, one of the fundamental forces in the universe.
May 14, 2023 · General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the...
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 ...
May 16, 2017 · By Mitch Waldrop. May 16, 2017. • 9 min read. Albert Einstein’s theory of relativity is famous for predicting some really weird but true phenomena, like astronauts aging slower than people on...
general relativity, part of the wide-ranging physical theory of relativity formed by the German-born physicist Albert Einstein. It was conceived by Einstein in 1916. General relativity is concerned with gravity, one of the fundamental forces in the universe. Gravity defines macroscopic behaviour, and so general relativity describes large-scale ...
Description of Albert Einstein's theory of relativity as a theory about what is absolute and not relative. (more) See all videos for this article.
In his special relativity theory, Einstein instead showed that the laws of physics and, crucially, the speed of light are the things that are constant. Fixing these meant that time and space could vary – and were two sides of the same ‘spacetime’ coin.
