The Laser Interferometer Gravitational-wave Observatory (LIGO) published
a monumental confirmation of classical physical theory: gravitational
waves exist. Very
few details have been derived from the signal they recorded though.
The gravitational wave was the last of the major prediction of Einstein’s world-changing theory that scientists had yet to confirm; according to Einstein’s understanding of spacetime, movements of mass should create moving ripples of gravitational force. The problem was that gravity is extremely weak when compared to pretty much any other force in the universe, so only the most monumentally enormous happenings could possibly create ripples big enough for scientists to detect. That’s where black holes come in.
