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

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. One of the most understated frontiers in all of physics is the quest ...

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 ...

An artist’s conception shows gravitational waves emanating like ripples in space time as two black holes approach each other in their orbits. (Credit: T. Pyle / LIGO) It looks as if gravitational-wave ...

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 ...
