Why 1916 is special
It described gravity as the curvature of spacetime rather than a force. Its prediction that starlight bends around the Sun was confirmed in 1919, which made Einstein internationally famous almost overnight.

Special relativity in 1905 and the general theory in 1916. The second extended the first to gravitation and accelerated frames, and took Einstein eleven years.

General relativity predicted that light passing the Sun would bend by a specific amount. Eddington's 1919 eclipse measurements matched it, and the confirmation turned a physicist into a public figure within weeks — an unusual trajectory for a field equation.
