Take a whirl above the massive LIGO gravitational wave detector

After decades of effort, physicists with the Laser Interferometer Gravitational-Wave Observatory (LIGO) say they're on the verge of detecting ripples in space and time called gravitational waves. Their detection would open a new window on the cosmos and fulfill perhaps the most spectacular prediction of Albert Einstein's general theory of relativity. Fly above the massive LIGO interferometer in Livingston, Louisiana and learn how physicists will search for those tiny, elusive signals.
