May 6, 2024 · E = mc 2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other. In the equation, the increased relativistic mass (m) of a body times the speed of light squared (c 2) is equal to the kinetic energy (E) of ...

Technically, general relativity is a theory of gravitation whose defining feature is its use of the Einstein field equations. The solutions of the field equations are metric tensors which define the topology of the spacetime and how objects move inertially.
[1] 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.
Special relativity revealed that the speed of light is a limit that can be approached but not reached by any material object; it is the origin of the most famous equation in science, E = mc 2; and it has led to other tantalizing outcomes, such as the “twin paradox.”
Following is a list of the frequently occurring equations in the theory of special relativity . Postulates of Special Relativity. To derive the equations of special relativity, one must start with two other. The laws of physics are invariant under transformations between inertial frames.
Special relativity also produced the most famous equation ever written: E = mc 2. It says that the energy ( E ) associated with an object – an atom, a person or a whole galaxy – is equal to its total mass ( m ) multiplied by the square of the speed of light (c).
