Which scientist proposed the theory of general relativity?

Albert Einstein proposed the theory of general relativity in 1915. This groundbreaking theory revolutionized our understanding of gravity by describing it as the curvature of spacetime caused by mass and energy, rather than as a force acting at a distance, as Newton suggested. General relativity explains phenomena such as gravitational time dilation, the bending of light near massive objects, and the expansion of the universe. Its predictions have been confirmed through numerous experiments and astronomical observations, including gravitational lensing and black hole imaging. The theory remains a cornerstone of modern astrophysics and cosmology, guiding research into dark matter and spacetime.
