Physicists were all abuzz in February 2016 with a universe-shaking announcement: Scientists had detected the sound of two massive black holes smashing into one another, forming a new black hole nearly twice as big.<\/p>\n
The sound came in the form of a brief burst of gravitational waves, vibrations that radiated from the collision-like ripples spreading on a pond, traveling more than a billion light-years before they reached Earth. This was the first time in history that anyone had directly detected gravitational waves.<\/p>\n<\/a>
