Northwestern’s has proposed a mini detector that could measure gravitational waves. Gravitational waves are disturbances in space time that are caused by processes like collision of black holes, combining of neutron stars etc, the kind seen when earth was formed. Einstein predicted in 1916 that such waves existed in his general theory of relativity, whose first evidence was found in 1974 .In one of great achievements of science massive(KM long)gravitational wave detectors were set in the US(LIGO) and Europe(VIRGO). Northwestern’s mini detector would use lasers to suspend a glass bead inside a vacuum chamber, creating an extremely force-sensitive sensor with arms just a meter long
