When Einstein proposed his new theory of gravity in 1915 his theory of General Relativity that massive objects curve space he came up with three ways of testing his theory. One of those ways was whether it could properly predict the orbit of Mercury, which up until then, no theory of gravity had been able to do. So why is Mercury's orbit so odd?
