General relativity takes the form of field equations, describing the curvature of space-time and the distribution of matter throughout space-time. Einstein’s theory of gravitation is expressed in one deceptively simple-looking tensor equation (tensors are a generalization of scalars and vectors), which expresses how a mass determines the curvature of space-time around it. Albert Einstein would revolutionize the way physicists saw gravity. The effects of […] Why talk of curvature? Einstein spent more than seven years developing it, and it was worth the wait. Albert Einstein came with his question about Newton’s Law of Gravitation: Suppose, there is a force that exists between two … Einstein derived his theory using mathematics. Instead, Einstein showed that gravity is a result of the warping, or curving, of space and time, which made up the same space-time “fabric.” These ideas about space-time and gravity became known as Einstein’s theory of general relativity. Since string theory is related to the theory of quantum gravity, a good place to begin is by giving an overview of the scientific understanding of gravity, which is defined by Einstein’s theory of general relativity. The solutions to that equation yield … The solutions to that equation yield … Einstein’s Gravity. Einstein’s theory of gravitation is expressed in one deceptively simple-looking tensor equation (tensors are a generalization of scalars and vectors), which expresses how a mass determines the curvature of space-time around it. If, as Newton claimed, gravity was a constant, instantaneous force, the information about a sudden change of mass would have to be somehow communicated across the entire universe at once. Instead of gravity as a force acting between objects, Einstein […] Visualizing Einstein’s Ideas. https://phys.org/news/2020-10-einstein-description-gravity-harder.html "At some level, the majority of physicists believe that Einstein's theory of gravity, called general relativity, is correct. General relativity was Einstein’s theory of gravity, published in 1915, which extended special relativity to take into account non-inertial frames of reference — areas that are accelerating with respect to each other. Einstein’s theory also triumphantly punched a hole in Newton’s logic. Einstein’s theory of gravitation is expressed in one deceptively simple-looking tensor equation (tensors are a generalization of scalars and vectors), which expresses how a mass determines the curvature of space-time around it. The most successful theory of gravity known to humanity is Einstein's famous theory of general relativity. In Einstein's hands gravitation theory was thus transformed from a theory of forces into the first dynamical theory of geometry, the geometry of four dimensional curved space-time. The solutions to that equation yield …
