a generalization of special relativity to include gravity (based on the principle of equivalence)
Source: WordNetIt is almost impossible to have a baseless snobbish opinion of the General Theory of Relativity. Michael Moorcock
Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out. Stephen Hawking
For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin. Stephen Hawking
In Einstein's general theory of relativity the identity of these two coefficients, the gravitational and the inertial mass, is no longer a miracle, but a necessity, because gravitation and inertia are identical. Willem de Sitter
Cosmology main collapsible In 1917, Einstein applied the general theory of relativity to the structure of the universe as a whole.sfn He discovered that the general field equations predicted a universe that was dynamic, either contracting or expanding. Source: Internet
Einstein 1920: We may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an aether. Source: Internet
