General relativity - Wikipedia
General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or four-dimensional spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever present matter and radiation.
Einstein's Theory of General Relativity - Space.com
2024年10月29日 · 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...
Einstein's Theory of Gravitation - Center for Astrophysics
In general relativity (GR), concentrations of mass and energy curve the structure of spacetime, affecting the motion of anything passing near — including light. The theory explained the anomalous orbit of Mercury, but the first major triumph came in 1919 when Arthur Eddington and his colleagues measured the influence of the Sun’s gravity on ...
Two-body problem in general relativity - Wikipedia
The two-body problem in general relativity (or relativistic two-body problem) is the determination of the motion and gravitational field of two bodies as described by the field equations of general relativity. Solving the Kepler problem is essential to calculate the bending of light by gravity and the motion of a planet orbiting its sun.
Tests of general relativity - Wikipedia
Tests of general relativity serve to establish observational evidence for the theory of general relativity. The first three tests, proposed by Albert Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.
General relativity | Gravitational Waves, Spacetime & Cosmology ...
2024年11月14日 · General relativity has been experimentally verified by observations of gravitational lenses, the orbit of the planet Mercury, the dilation of time in Earth’s gravitational field, and gravitational waves from merging black holes.
General relativity: How Einstein's theory explains the universe, …
2015年11月25日 · General relativity lets us calculate and predict exactly how anything with mass will warp spacetime, and how the gravity caused by that warped spacetime will affect not just the matter, but the space, time and light around it.
General relativity is the theory of space and time and gravity. The essence of the theory is simple: gravity is geometry. The effects that we attribute to the force of gravity are due to the bending and warping of spacetime, from falling cats, to orbiting spinning planets, to the motion of the cosmos on the grandest scale. The purpose of
How Albert Einstein Developed the Theory of General Relativity
Black holes and the expanding universe are two concepts that have their roots in general relativity. Even GPS satellites must account for general relativistic effects to deliver accurate position measurements to people on Earth. Learn how one of history’s greatest minds came up with one of science’s most important theories.
Einstein’s general relativity reveals new quirk of Mercury orbit ...
2018年4月11日 · Planets in the solar system move in elliptical orbits that gradually rotate as each planet journeys around the sun. That rotation is mainly due to gravitational tugs from the other planets....
