Two new probable gravitational waves—ripples in the fabric of spacetime caused by cataclysmic cosmic events and first predicted by Albert Einstein over 100 years ago—have been detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo observatory in Italy in the first weeks after the detectors were updated. The source of both waves is believed to be the merging of a pair of black holes.

LIGO, the world’s largest gravitational-wave observatory, once considered a “total waste of money,” has nearly doubled its capability to detect gravitational waves and is now more sensitive than ever to the tiny ripples in spacetime generated when black holes and dead stars collide. The broader capability is a result of numerous upgrades to the lasers, mirrors, and quantum noise filters at LIGO’s facilities in Washington state and Louisiana, making it possible to scan about twice the volume of space for smashups between two black holes or two neutron stars.

The LIGO and Virgo laser interferometer gravitational-wave observatories in the U.S. and Italy have begun a third yearlong observation run with the hope of yielding new astronomical observations. The O3 run, as it is being called, will likely add to the milestones achieved in the first two runs. These include the detection of gravitational waves from 10 binary black-hole mergers and from the collision of a pair of ultradense neutron stars. The latter detection, coordinated with observations from more traditional optical, x-ray, and gamma-ray telescopes in an example of “multimessenger astronomy,” resulted in new scientific information. This current run comes just three years after the first detection of gravitational waves (GW). The LIGO/Virgo Scientific Collaboration (LSC) will make data about possible GW detections publicly available in near real time. LSC scientists are

22:41 WhatReallyHappened.comGrave doubts over LIGO’s discovery of gravitational waves

THERE was never much doubt that we would observe gravitational waves sooner or later. This rhythmic squeezing and stretching of space and time is a natural consequence of one of science’s most well-established theories, Einstein’s general relativity. So when we built a machine capable of observing the waves, it seemed that it would be only a matter of time before a detection.
In point of fact, it took two days. The Laser Interferometer Gravitational-Wave Observatory collaboration, better known as LIGO, switched on its upgraded detectors on 12 September 2015. Within 48 hours, it had made its first detection. It took a few months before the researchers were confident enough in the signal to announce a discovery. Headlines around the world soon heralded one of the greatest scientific breakthroughs of the past century. In 2017, a Nobel prize followed. Five other waves have since been

Black holes colliding, gravitational waves riding through space-time - and a huge instrument that allows scientists to investigate the fabric of the universe. This could soon become reality when the Laser Interferometer Space Antenna (LISA) takes up operations. Researchers have now found that LISA could also shed light on the elusive dark matter particle.
