4 days ago · General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
3 days ago · Special relativity rests on two postulates: that the laws of physics are the same in all inertial (non-accelerating) reference frames; and that the velocity of light in empty space, c, is the...

5 days ago · The marriage of special relativity and quantum mechanics in the 1930s allowed for the prediction of antimatter and soon led to the birth of particle physics via quantum field theory.

The Michelson–Morley experiment was an attempt to measure the motion of the Earth relative to the luminiferous aether, [A 1] a supposed medium permeating space that was thought to be the carrier of light waves. The experiment was performed between April and July 1887 ...
3 days ago · In 1915, Albert Einstein proposed general relativity, a fundamental theory in physics. It defines gravity as a geometric property of spacetime in which massive objects such as stars and planets warp the fabric of space and time, causing other objects to move in curved paths.
4 days ago · His special theory of relativity, which explains the relationship between mass, time and space, suggests that as an object approaches the speed of light, its mass and energy become...
5 days ago · 1911 – Albert Einstein explains the need to replace both special relativity and Newton's theory of gravity; he realizes that the principle of equivalence only holds locally, not globally. 1915-16 – Albert Einstein completes his general theory of relativity.
