[collision] Welcome to LIGO Hanford Observatory, located in the Columbia Basin region of southeastern Washington. LIGO, the Laser Interferometer Gravitational-wave Observatory, seeks to detect gravitational waves -- ripples in the fabric of spacetime. First predicted by Einstein in his theory of general relativity, gravitational waves are produced by exotic events involving black holes, neutron stars and objects perhaps not yet discovered. Use our links to explore LIGO science, public outreach and educational resources.
