General relativity, also known as the general theory of relativity, and as Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1916 and is the …

Dec 18, 2025 · General relativity is concerned with gravity, one of the fundamental forces in the universe. Gravity defines macroscopic behaviour, and so general relativity describes large …

Oct 29, 2024 · General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time.

In general relativity (GR), concentrations of mass and energy curve the structure of spacetime, affecting the motion of anything passing near — including light.

May 5, 2025 · General relativity extended the principle of relativity to include acceleration and redefined gravity not as a force, but as a geometric property of spacetime. Einstein’s central …

Nov 27, 2022 · Einstein's Theory of General Relativity is our current best model of gravity. It expands on the ideas of special relativity in a way that accounts for an apparent paradox when …

Along with Einstein's idea from special relativity that physics has no preferred coordinate system, it forms the cornerstone of the conceptual foundation of general relativity.

The theory of relativity comprises two physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. [1] Special relativity …

Apr 5, 2023 · General relativity (GR), also known as the General Theory of Relativity, is an extension of special relativity, dealing with curved coordinate systems, accelerating frames of …

This page features an overview of all our Spotlights on Relativity dealing with the basic features of general relativity. The spotlight texts under the heading Fundamentals deal with the …
