This video is Episode 9 of the multi-part Advanced LIGO Documentary Project by Les Guthman. Titled "aLIGO SNAPS," it brings together into one episode all eight of the aLIGO SNAPS -- the short profiles that conclude each episode. The SNAPS are: "Max Isi and Sarah Gossan," "Teresita Ramirez," "Squeezed Light," "First Light," "Janeen Romie," "A New Measure of the Universe," "Barry Barish: The Nobel Book," and "Into the Unknown," in which Stan Whitcomb talks about what will happen when LIGO detects a signal it can’t explain.
