In late 2017, when we learned the Nobel Prize in Physics had gone to the team that discovered gravitational waves using LIGO (The Laser Interferometer Gravitational-Wave Observatory) we rushed to finish this short piece about how LIGO works.

A special thanks to Caltech and SC17 for providing the opportunity to tell this story. Jennifer Boyd, Erik Angra, Tom Nelson, Rena DeBortoliJim Chapdelaine, Scott Persson and Michael Bacon worked to create this video.
