The loudest gravitational wave ever recorded, GW250114, has travelled 1.3 billion light-years to Earth, reinforcing Einstein's century-old theory of relativity.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. One of the greatest scientific achievements in all of human history was ...

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 ...

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 Scientific Collaboration and Virgo Collaboration released a catalog of results from the first half of its third observing run (O3a), and scientists have detected more than three times as many ...

Think of spacetime as a rubber sheet, which is stretched when there are large objects such as stars and black holes. Gravitational waves are the waves on this cloth, which are produced when the masses ...

For 13 years, the scientists of LIGO—the most ambitious, and expensive, project in the history of the National Science Foundation—had been waiting. LIGO, the Laser Interferometer Gravitational-Wave ...

Earth is awash in gravitational waves. Over a six-month period, scientists captured a bounty of 39 sets of gravitational waves. The waves, which stretch and squeeze the fabric of spacetime, were ...

After a year of downtime to perform hardware upgrades, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is ready for action and will turn on its twin detectors, one in Washington state ...
