Abstract
In 2015, a huge scientific collaboration called LIGO discovered gravitational waves. Gravitational waves are huge ripples in spacetime that occur as a result of astrophysical events, like collisions between massive things in outer space. In 2015, the LIGO scientists found a signal that came from two black holes merging. This was huge scientific news, and resulted in the 2017 Nobel Prize in Physics for Rai Weiss, Kip Thorne, and Barry Barish.
