Laser Interferometer Gravitational Wave Observatory
A device to detect gravitational waves and its use to probe the universe has been a dream of theoretical physicists for several decades
LIGO is such a device. I should detect gravitational waves from sources such as black-hole collisions, the pulsations of newborn neutron stars resulting from supernovae explosions, and the background remnants of the Big Bang itself.
