Gravitational Waves Detected, Confirming Einstein’s Theory

Predicted 100 years ago:

Einstein was not quite sure about these waves. In 1916, he told Karl Schwarzschild, the discoverer of black holes, that gravitational waves did not exist, then said they did. In 1936, he and his assistant Nathan Rosen set out to publish a paper debunking the idea before doing the same flip-flop again.

Huge step in our understanding of the Universe.
