Nov 25, 2023 · Albert Einstein proposed these theories starting in 1905. By the 1920s, they were widely accepted by physicists. Special relativity involves two key ideas. First, the speed of light in a vacuum is the same for any observer, regardless of the observer’s location or motion, or the location or motion of the light source.
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.

The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity .
Jan 31, 2024 · Einstein's theory of relativity proved to provide solutions to some of the phenomena that scientists had been unable to reconcile with classical physics. Einstein's relativity theory unified the three basic theory complexes: the law of gravity, electrodynamics, and thermodynamics.
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.
