Question

Quizplus · Accepted Answer

One of the first and most famous tests of the general theory of relativity was the explanation of the anomalous precession of Mercury's perihelion. Before Einstein's theory, the observed precession of Mercury's orbit could not be fully explained by Newtonian mechanics and the gravitational effects of other planets. General relativity accounted for the discrepancy.
