An upgrade to LIGO that comes from exploiting a quantum rule known as the Heisenberg uncertainty principle makes it easier to detect spacetime ripples.

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the LIGO observatories. The powerful merger produced a ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123 ...

May 24 marked the start of O4, the latest gravitational-wave hunting effort of the LIGO-Virgo-KAGRA Collaboration. But only LIGO is fully operational right now.

Scientists say they detected the largest-ever merger of two black holes, forming one that is 225 times the mass of the sun, adding that the new discovery "pushes the limits of" how astronomers ...
