Although Einstein’s general theory of relativity has served as a robust classical description of gravity that holds true under most circumstances, the classical theory breaks down under extreme ...
Besides quantum theory, general relativity is one of two ... “space-time”, you can construct a picture in which gravity is just a form of acceleration. Massive objects bend space-time around ...
The trouble boils down to gravity. It’s the only one of the four fundamental forces of nature described by general relativity, and the only one that quantum theory cannot address. Coming up with ...
