| Laser Interferometer Gravitational-Wave |
A project by California Institute of Technology and the Massachusetts Institute of Technology to construct a detector of gravitational waves in the USA. It will consist of detectors in Washington State and Louisiana. Each L-shaped installation will beam laser light down 4-kilometre-long 2.5-mile, evacuated tubes. Changes in the length of the light path caused by gravitational waves should register in the detectors.
