Summary:
Since Galileo first turned a telescope to the heavens, astronomers have studied the planets, the stars and distant galaxies. But there are some mysteries so deep, the answers cannot be found with traditional tools. For those, it takes something entirely different: A revolutionary new kind of observatory built to detect the whisper of a signal that's never been directly measured. This award-winning documentary takes viewers inside the National Science Foundation's Laser Interferometer Gravitational Wave Observatory (LIGO), where scientists are spearheading the completely new and radical field of gravitational wave astronomy and opening a whole new window on the universe. It explains how LIGO's exquisitely sensitive instruments may ultimately take us farther back in time than we've ever been, catching, perhaps, the first murmurs of the universe in formation. This is a compelling and thought-provoking production about the drama of the scientific quest.
