網頁4 天前 · On its own, general relativity could predict the expansion of the universe, which (through observations such as the bending of light by large masses, or the precession of the orbit of Mercury) could be experimentally observed and compared to his theoretical calculations using particular solutions of the equations he had originally formulated.
Albert Einstein | Biography, Education, Discoveries, & Facts
網頁2024年6月5日 · Albert Einstein (born March 14, 1879, Ulm, Württemberg, Germany—died April 18, 1955, Princeton, New Jersey, U.S.) was a German-born physicist who developed the special and general theories of relativity and won the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect.
Why We Can't Avoid Singularity Inside Every Black Hole
網頁5 天前 · General Relativity tells us that when a massive star collapses under its own gravity, it forms a black hole with a singularity at its center. At this singularity, spacetime—our concept of space and time—gets twisted beyond recognition, and the usual laws of physics break down. The equations of General Relativity predict that at this point ...
Black hole - Wikipedia
網頁5 天前 · In general relativity, however, there exists an innermost stable circular orbit (often called the ISCO), for which any infinitesimal inward perturbations to a circular orbit will lead to spiraling into the black hole, and any outward perturbations will, depending on the energy, result in spiraling in, stably orbiting between apastron and periastron, or …

網頁6 天前 · In general relativity, physical spacetime is modeled in terms of differential geometry as a Lorentzian manifold whose pseudo-Riemannian metric – or rather the Levi-Civita connection that corresponds to it – encodes the field of gravity.
Theory of Relativity - Discovery, Postulates, Facts, and Examples
網頁2024年6月5日 · Albert Einstein developed the general theory of relativity from 1907 to 1915. The general theory of relativity is also known as the theory of gravitation. According to this theory, the gravitational force between two bodies completely depends on their masses and on the distance between two bodies.
