If two black holes collide, then Einstein's general theory is proven true and gravitational waves are propagated throughout the universe. Either two black holes collide, or space-time is distorted and Einstein's general theory is proven true. Therefore, Einstein's general theory is proven true. (T = Two black holes collide. E = Einstein's general theory is proven true. G = Gravitational waves are propagated throughout the universe. S = Space-time is distorted.)
