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 …

WEBIn his four papers, published in November 1915, Einstein laid the foundation of the theory. In the third in particular he used general relativity to explain the precession of the perihelion of Mercury. The point at which Mercury …
General relativity | New Scientist
WEBvchal/Getty Images. Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short ...
General Relativity For Dummies: An Intuitive Introduction
WEBAs a brief introduction, general relativity is the most accurate theory of gravity so far, introduced by Albert Einstein in the early 1900s. General relativity explains gravity as a property of spacetime rather than a force, namely, as the curvature of spacetime, which is caused by matter and energy. Now, while the mathematical structure of ...
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 ...
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 …

WEB14 Sep 2010 · Special Relativity and General Relativity. The theory of general relativity better enables us to study distant stars. Let's heap a second scoop onto the relativity cone -- a lovely taste of Black Forest courtesy of German-born physicist Albert Einstein. As we just mentioned, Galilean relativity, even after it got a few tweaks from Newtonian ...
Special relativity - Wikipedia
WEBt. e. In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein 's 1905 treatment, the theory is presented as being based on just two postulates: [p 1] [1] [2] The laws of physics are invariant (identical) in all inertial frames of ...
