On November 25, 1915, Albert Einstein submitted his paper "The Field Equations of Gravitation" to the Prussian Academy of Science in Berlin, completing his general theory of relativity. The theory describes gravity as a geometric property of spacetime, where massive objects create curvature that affects the paths of other objects and light. Einstein's equations explained Mercury's perihelion precession and predicted light bending near the Sun, which confirmation during the 1919 solar eclipse brought Einstein international recognition.
