The Chirp Heard Round the World: How Scientists Confirmed the LIGO Detection

It’s been a year since researchers with the Laser Interferometer Gravitational-wave Observatory (LIGO) announced the first direct observations of gravitational waves, the oscillations in the fabric of space and time created by powerful cosmic events—like the merging of two massive black holes. This cosmic phenomenon was first predicted by Einstein in 1915, but it took a century…

Scientists Prove It’s Still Einstein’s Universe and We’re All Just Living In It

In what has truly turned out to be a momentous occasion in astrophysics, today scientists announced the first-ever direct observation of gravitational waves by the Laser Interferometer Gravitational-wave Observatory (LIGO) experiment, which consists of two enormous detector facilities located in Louisiana and Washington state and an international consortium of thousands of researchers. First predicted by Albert Einstein in…
