Einstein vs. the Particle

It doesn't really make sense ~ yet. Einstein's Theory of Relativity (1916) can explain everything in the known universe except the realities of quantum mechanics. Does this mean it should be scrapped or merely readjusted or something else entirely? We may have the opportunity to test the theory to its core very soon, as a gas cloud called G2 closes in on the black hole at the center of the Milky Way: http://www.newscientist.com/article/mg21829154.700-black-hole-binge-could-test-general-relativity.html
