Physicists Report New, Solid Observation of Gravitational Waves

It’s pretty much official now: there are gravitational waves. A collaboration between the LIGO Lab and the Virgo interferometer collaboration just reported the first joint detection of gravitational waves, adding much more weight to previous detection events. It’s not the first time gravitational waves had been detected. Physicists had recorded…
