LIGO Livingston in Louisiana, USA, where researchers detect gravitational waves. “This technology will help us not only improve LIGO but also to build next-generation, even bigger gravitational-wave detectors.”LIGO’s interferometers, located in the US states of Louisiana and Washington, detect gravitational waves – undulations in space-time which ripple out from colliding cosmic bodies. As gravitational waves reach Earth, they stretch and contract these arms by almost imperceptible amounts. Improved low-frequency sensitivity of gravitational wave observatories would also make it easier for LIGO to detect black holes with eccentric (oblong) orbits. LIGO researchers approached DeepMind to develop an AI to control this noise better than the traditional feedback control system.
