Gravitational Waves Discovered

Without exception, Gravitational Wave discoveries are one of the most important developments in all of science. Predicted by Einstein in 1911, they were finally observed in 2016. This is part of my complete intro Astronomy class that I taught at Willam Paterson University and CUNY Hunter.
