New movie on LIGO's Mirror suspensions

The Advanced LIGO Documentary project released an 8 minute video looking at the suspension system that holds up LIGO's Mirrors.  LIGO achieves its extraordinary sensitivity partially by hanging its mirrors so that ground vibrations don't disturb them.  Each mirror is a pendulum, and this video available on vimeo (or in our own media gallery) explores in simple language how hanging the mirrors helps LIGO detect gravitational waves.
