One of Einstein's greatest achievements was the Theory of General Relativity, which is a theory of gravitation, developed between 1907 and 1915, according to which, "the observed gravitational attraction between masses results from the warping of space and time by those masses." 2/

Some phenomena which were not explained by Newton's theory of gravity (e.g. the 'wobble' of Mercury's orbit) fit into the Theory of General Relativity, which also predicted other phenomena (e.g. deflection of light by the Sun) 3/
