The primary assumption of General Relativity is that matter "warps" space. "Warps" means: causes a depression that holds mass in place or motion, while its depression moves towards all other such depressions in space.
The second assumption is the Riemann geometry and tensor calculus can be used to explain the motions of all matter and light within a 4 dimensional Minkowski spacetime manifold.
The scientific Theories of General and Special Relativity were first proposed by Albert Einstein.Special Relativity in 1906 and General Relativity in 1916.
General Relativity - book - was created in 1984.
E=mc^2 Edit : That equation is part of "special relativity" not "general relativity".
General Relativity - book - has 491 pages.
The ISBN of General Relativity - book - is 0-226-87033-2.
Before you depend on this "General Relativity", you should check what it depend on. It relativises its reference frames, arguments, concepts, imaginations, assumptions in a big and complicated circle --- its base is relative. If you want to lean on something based on that shaky ground, it's your choice.
Galilean Relativity - Galileo Galilei Special and General Relativity - Albert Einstein
The Theory of Special Relativity was published in 1905. General Relativity was published in 1915.
The General theory of relativity primarily applies to particles as they accelerate, particularly due to gravitation
At first people thought that General Relativity was a bizarre and irrelevant theory. However, as time went by, people started to accept General Relativity more and more.
Galileo Galile wrote "the Theory of Relativity", and Einstein wrote the General theory of relativity and the special theory of relativity.
