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.
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.

Apr 13, 2018 · Albert Einstein is famous for his theory of relativity, and GPS navigation and nuclear energy would be impossible without the equation e=mc2. How our ideas about space and time changed forever.
May 16, 2017 · Albert Einstein’s theory of relativity is famous for predicting some really weird but true phenomena, like astronauts aging slower than people on Earth and solid objects changing their shapes...
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 theory of special...
Jul 2, 2019 · What is relativity? Succinctly put, it is the notion that the laws of physics are the same everywhere. We here on Earth obey the same laws of light and gravity as someone in a far off corner of...
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).
The general theory of relativity (or general relativity for short) is a major building block of modern physics. It explains gravity based on the way space can 'curve', or, to put it more accurately, it associates the force of gravity with the changing geometry of space-time.
In his four papers, published in November 1915, Einstein laid the foundation of the theory. In the third in particular he used general relativity to explain the precession of the perihelion of Mercury. The point at which Mercury has its closest approach to the Sun, its perihelion, moves.
