Marcia Bartusiak joins Kip Thorne, Laura Danly and Rainer Weiss to demonstrate how two observatories on opposite sides of the country, called LIGO (Laser Interferometer Gravitational-wave Observatory), may open a new window on observing the cosmos—one based not in light but in gravity. Scientists have embarked on this joint experiment, seeking whispers of far-away violence—like the collision between distant black holes—rippling through the cosmos. It’s taken nearly a century, but technology has finally caught up to Einstein’s brilliance. His 1916 General Theory of Relativity predicted the existence of gravitational waves—undulations in the very fabric of space and time—and LIGO researchers are now poised to detect them.
