Há 3 dias · General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
21 de jun. de 2024 · In Einstein’s theory of general relativity, the physical consequences of gravitational fields are stated in the following way. Space-time is a four-dimensional non-Euclidean continuum, and the curvature of the Riemannian geometry of space-time is produced by or related to the distribution of matter in the world.
Há 6 dias · Einstein was convinced that general relativity was correct because of its mathematical beauty and because it accurately predicted the precession of the perihelion of Mercury’s orbit around the Sun (see Mercury: Mercury in tests of relativity).
16 de jun. de 2024 · The theory of relativity encompasses the gravitational force, one of the four fundamental forces in the Universe. Conversely, the Standard Model encompasses the other three forces—nuclear...
Há 6 dias · 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.
Há 1 dia · July 1, 2024. Researchers have built an atomic clock that is more precise and accurate than any previous clock. For the first time, the clock can detect the effects of gravity predicted by the theory of general relativity at the microscopic scale. The clock is the latest demonstration that a much more precise definition of the official second ...
Há 3 dias · General relativity also breaks down at the very small scale. This is where quantum theory takes over — an entirely different set of rules that tells us how subatomic particles, such as photons ...
