What best explains the influence of Einstein's general theory of relativity?

Einstein's general theory of relativity revolutionized our understanding of gravity, showing that it arises as a result of the curvature of spacetime by matter and energy. It explains phenomena like the bending of light around massive objects, the existence of black holes, and the expansion of the universe. Its predictions have been confirmed by numerous observations and experiments, solidifying its influence on modern physics and our perception of the cosmos.
