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 ...

Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...

The Laser Interferometer Gravitational-Wave Observatory, or LIGO, has already won its researchers a Nobel Prize — and now artificial intelligence is poised to take LIGO’s search for cosmic collisions ...

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 facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

Physicists have detected the biggest ever merger of colliding black holes. The discovery has major implications for researchers’ understanding of how such bodies grow in the Universe. “It’s super ...

"We can now reach the deeper universe and are expecting to detect about 60 percent more mergers than before." When you purchase through links on our site, we may earn an affiliate commission. Here’s ...
