"The collision, which caused a gravitational wave, or sudden ripple in space-time, was observed on November 23, 2023, just before 13:00 GMT by two detectors simultaneously. These detectors, in the US states of Washington State and Louisiana, are operated by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and are part of the LIGO-Virgo-KAGRA (LVK) network. The LIGO comprises two large-scale laser interferometers, which act as antennae to detect gravitational waves."
"Black holes are cosmic objects, or regions of space, which comprise a large concentration of matter packed into a relatively tiny space. The enormous amount of mass packed into a small space creates a gravitational pull so strong that nothing, not even light, can escape it. As no light is emitted from black holes, rendering them invisible, we do not know what, exactly, is inside them."
"The gravitational wave, which was detected for 0.1 seconds as a result of the collision, was named GW231123. LIGO, which is funded by the US National Science Foundation, is a large-scale physics observatory that detects gravitational waves using highly sensitive laser interferometers. It was designed and built by scientists and engineers at the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT)."
Scientists discovered the biggest-known merger of two black holes using gravitational wave detectors. The collision was recorded on November 23, 2023 and produced a gravitational wave named GW231123. The wave was observed for 0.1 seconds by two LIGO detectors in Washington State and Louisiana, part of the LIGO-Virgo-KAGRA network. LIGO comprises two large-scale laser interferometers that act as antennae to detect gravitational waves and is funded by the US National Science Foundation. LIGO was designed and built by Caltech and MIT. The findings were presented at the International Conference on General Relativity and Gravitation in Glasgow.
