CATCH A WAVE

Fred Raab, director of the Laser Interferometer Gravitational-Wave Observatory (LIGO) near Richland, Wash., explains on Friday, Feb. 22, 2002, how laser light traveling through a pair of 2.5-mile-long vacuum tubes will hopefully help the observatory measure gravitational waves from space. LIGO is set to become operational this summer to try to measure evidence of violent space events such as the blasts of a supernova or collisions of black holes. (AP Photo/Jackie Johnston)
