Relativity - Space-Time, Gravity, Physics | Britannica
WebGeneral relativity Roots of general relativity. Because Isaac Newton’s law of gravity served so well in explaining the behaviour of the solar system, the question arises why it was necessary to develop a new theory of gravity. The answer is that Newton’s theory violates special relativity, for it requires an unspecified “action at a distance” through …
Einstein's Theory of Gravitation | Center for Astrophysics
WebGeneral relativity showed that gravitation has a speed, which is the same as the speed of light. Catastrophic events like collisions between black holes or neutron stars produce gravitational waves. Researchers finally detected these waves in 2015 using the Laser Interferometer Gravitational Observatory (LIGO), a sensitive laboratory that took decades …

General Relativity explained like you've never seen before
WebFor 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. That means if you feel no force you’ll either sit still or glide ...
