Einstein's general theory of relativity confirmed: Gravitational waves observed for the first time

Gravitational waves, the ripples in the spacetime fabric, were observed for the first time, the scientists confirmed on February 11, 2016. The waves resulted from a cataclysmic event of two black holes merging in the distant universe. Their existence, first...
