You can now watch a new, 20-minute film that chronicles the people and strange science behind an amazing astronomical tool that uses lasers to search for violent cosmic events trillions of miles from Earth. The documentary "LIGO, A Passion for Understanding," by filmmaker Kai Staats, follows scientists using the Laser Interferometer Gravitational-wave Observatories (LIGO) to hunt for gravitational waves — ripples in space-time created by cataclysmic events in the cosmos. You can watch the full film in the window above or directly through this link: LIGO, A Passion for Understanding
