3rd Gravitational Wave detection doubted as noise by a team
Gravitational Wave detections are made by two synchronised LIGO detectors separated by 3,000 km to cross-check other's observations for noise in the signal. However, a group of scientists studying LIGO's public data claim the third detection appears to have correlated noise simultaneously. They have called for a "re-evaluation of the signals with a more careful consideration of noise properties."
