The Story Behind Discovering Gravitational Waves

Nicola Twilley, writing for The New Yorker, with the behind the scenes look at the scientists that discovered gravitational waves exist:

The fact that gravitational waves were detected so early prompted confusion and disbelief. “I had told everyone that we wouldn’t see anything until 2017 or 2018,” Reitze said. Janna Levin, a professor of astrophysics at Barnard College and Columbia University, who is not a member of the LIGO Scientific Collaboration, was equally surprised. “When the rumors started, I was like, Come on!” she said. “They only just got it locked!” The signal, moreover, was almost too perfect. “Most of us thought that, when we ever saw such a thing, it would be something that you would need many, many computers and calculations to drag out of the noise,” Weiss said. Many of his colleagues assumed that the signal was some kind of test.
