3 days ago · General relativity can be understood by examining its similarities with and departures from classical physics. The first step is the realization that classical mechanics and Newton's law of gravity admit a geometric description.
Apr 6, 2024 · While general relativity is a complex theory, it can be understood by anyone with an interest in the universe. Key Takeaways. General relativity is a theory that explains gravity as the curvature of spacetime. The mathematics of general relativity involves complex equations that describe the behavior of matter and energy in spacetime.
Apr 8, 2024 · General Relativity makes specific predictions about how the light emitted from material in the inner-most regions around a black hole is distorted and gravitationally redshifted. Detailed observations of that light will provide stringent tests of strong gravity.
Apr 10, 2024 · 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.
Mar 31, 2024 · The actual path, as in the orbit of a planet, is found by solving a differential equation. In general relativity, one must solve Einstein’s equations for a given situation to determine the corresponding structure of space-time, and then solve a second set of equations to find the path of a particle.

Apr 12, 2024 · Special relativity revealed that the speed of light is a limit that can be approached but not reached by any material object. It is the origin of the most famous equation in science , E = m c 2 , which expresses the fact that mass and energy are the same physical entity and can be changed into each other.
