Learn how Einstein's theory of relativity links space and time, and how it affects mass, energy, and gravity. Find out the difference between special and general relativity, and the famous equation e=mc2.
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. [1] Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its ...
Apr 13, 2018 · What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or ...
Learn about Einstein's theories of special and general relativity, which overthrew many assumptions of earlier physics and redefined space, time, matter, and gravity. Explore the history, concepts, and applications of relativity, from the speed of light to the cosmic processes.
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 ...

May 16, 2017 · Learn how Einstein used visualization and imagination to create his famous equation that revolutionized physics. Follow his thought experiments with lightning, trains, and clocks to understand how space and time are relative.
For 100 years, the general theory of relativity has been a pillar of modern physics. The basic idea is so elegant that you don’t need superpowers to understand it. Begin with Isaac Newton’s first law of motion: An object remains in uniform motion unless acted on by a force.
