It took 100 years, but finally, scientists proved Albert Einstein’s theory that gravitational waves exist. The waves were predicted as part of Einstein’s General Theory of Relativity nearly 100 years ago. It was the theory of the physics behind the workings of our world and the universe. The idea was that the waves are like ripples in space, caused by some of the violent and energetic processes in the Universe. For example, two black holes crashing into each other. Now a group of scientists, including ones from from CalTech, MIT and the LIGO Scientific Collaboration finally found the gravitational waves. David Reitze is the executive director of the LIGO observatory at CalTech. “We have detected gravitational waves. We did it! (applause)”
