Historic Gravitational Waves Rippled, But Left No Fireworks

"This first attempt to detect visible light associated with gravitational waves was very challenging, but it paves the way to a whole new field of astrophysics," Edo Berger of the Harvard-Smithsonian Center for Astrophysics said in a statement. Berger was the principal investigator of a team t
