Implication

Experimental study reveals coincident signals across spaced gravitational wave detectors, suggesting detection of common external gravitational radiation.

Key Points

To evaluate whether spatially separated gravitational wave detectors register coincident signals indicative of a shared external excitation such as gravitational radiation.
Operated two gravitational wave detectors spaced approximately 2 km apart.
Recorded coincident signals and analyzed the statistical likelihood of random simultaneous events.
Observed a number of coincident events occurring simultaneously in both detectors.
Determined that the probability of these coincident events occurring due to statistical chance is extremely small, confirming response to an external excitation.
