The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves, using the US National Science Foundation-funded (NSF) LIGO ...

After a three-year hiatus made longer by pandemic troubles, the search for gravitational waves — ripples in space-time that are the hallmarks of colliding black holes and other cosmic cataclysms — has ...

On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to ...

The LIGO Hanford Observatory near Richland is expected to detect 60% more cataclysmic cosmic events — like colliding neutron stars and black holes — thanks to a quantum limit breakthrough. Since the ...

Putting the squeeze on light improves gravitational wave observatories. An upgrade to one such observatory, LIGO, that comes from exploiting a quantum rule known as the Heisenberg uncertainty ...

LIGO Hanford detected record-setting black hole merger, challenging current knowledge. Merged black holes spun near general relativity’s limit, baffling scientists. Funding cuts threaten U.S.
