Two large, "L"-shaped instruments separated by 1,865 miles are eavesdropping on the most extreme events in the universe. The two Laser Interferometer Gravitational-Wave Observatory (LIGO) sites, ...
Scientists on the lookout for subtle disturbances in the fabric of space-time have detected the signal from a cataclysmic collision between two black holes that lie some 3 billion light-years away, ...
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 ...
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 ...
Whenever a star is born in the Universe, its eventual fate is almost completely determined from the moment nuclear fusion ignites in its core. Dependent only on a few factors — mass, the presence of ...
Today, the team behind the Laser Interferometer Gravitational-Wave Observatory (LIGO) is announcing the detection of a third black hole merger, the first from its second operational run. The merger ...
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 ...
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 ...
About 1.4 billion years ago, the universe gave scientists a Christmas present. Two black holes spiraled toward one another, approaching closer and closer until they finally collided. Ripples in ...
The LIGO detector has now seen at least two black hole mergers. The second merger it spotted was about what we would expect given a binary system of two massive stars. Both explode, leaving black ...
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 ...
New mirror coatings will increase the volume of space LIGO can probe in its next run. Since LIGO's groundbreaking detection, in 2015, of gravitational waves produced by a pair of colliding black holes ...
