General relativity is a theory of gravitation developed by Albert Einstein between 1907 and 1915. The theory of general relativity says that the observed gravitational effect between masses results from their warping of spacetime.
May 14, 2023 · General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has...
Learn what general relativity is, how Einstein developed it, and why it explains gravity based on the curvature of space-time. Find out how general relativity differs from quantum mechanics and why it remains a challenge for modern physics.
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.
Learn how Einstein's theory of gravity is the warping of spacetime with a simple analogy of a roof. Explore the basic idea and its implications with an interactive comic that lets you manipulate the diagrams.
