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.
noun. the state or fact of being relative. Physics. a theory, formulated essentially by Albert Einstein, that all motion must be defined relative to a frame of reference and that space and time are relative rather than absolute concepts: it consists of two principal parts.
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.

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.
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...

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...
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). As the speed of light is about 300,000 km s -1, this means there is a whole lot of energy tied up in any mass.
