LIVINGSTON, LOUISIANA-- Physicists are preparing the first experiments with a real chance to spy the elusive gravitational ripples predicted by Einstein to fill space. One is an elaborate apparatus here and a near-twin across the continent in Hanford, Washington, that forms a $365 million venture known as the Laser Interferometer Gravitational-Wave Observatory, or LIGO. But success may take many years--and come in unexpected guises.
