Einstein’s mass-energy relation. special relativity, part of the wide-ranging physical theory of relativity formed by the German-born physicist Albert Einstein. It was conceived by Einstein in 1905. Along with quantum mechanics, relativity is central to modern physics. relativity of simultaneity.
General Theory of Relativity. General Relativity theory, developed by Einstein in 1907-1915, states that being at rest in the gravitational field and accelerating are identical physically. For example, an observer can see the ball fall the same way on the rocket and on Earth. This is due to the rocket’s acceleration, which equals 9.8 m/s 2.
This latter theory deals with the extension of the Special Theory to the case of the law of gravitation; we shall not discuss the General Theory here. The principle of relativity was first stated by Newton, in one of his corollaries to the laws of motion: “The motions of bodies included in a given space are the same among themselves, whether ...
The general theory of relativity explains gravity as a distortion in spacetime. According to general relativity, objects warp the fabric of spacetime like a weight resting on a trampoline, and the ...

relativity, Concept in physics that measurements change when considered by observers in various states of motion. In classical physics, it was assumed that all observers anywhere in the universe would obtain identical measurements of space and time intervals. According to relativity theory, this is not so; all measurements depend on the ...
General relativity is Einstein's theory of gravity, in which gravitational forces are presented as a consequence of the curvature of spacetime. In general relativity, objects moving under gravitational attraction are merely flowing along the "paths of least resistance" in a curved, non-Euclidean space. The amount that spacetime curves depends on the matter and energy present in ...
Jul 2, 2019 · Einstein's theory is divided into special and general relativity. Special relativity came first and is based on the speed of light being constant for everyone. That may seem simple enough, but it ...
