The detection of Einstein's gravitational waves relies on highly precise laser measurements of small length changes. The kilometer-size detectors of the international network (GEO600,... more
The gravitational waves created in the depths of space indeed reach Earth. Their effects, however, are so small that they could only be observed so far using kilometer-long measurement facilities. Physicists therefore discuss whether... more
In 2016, an international team of scientists found definitive evidence—tiny ripples in space known as gravitational waves—to support one of the last remaining untested predictions of Einstein's theory of general... more
The records of cataclysmic cosmic events, including four black hole observations disclosed for the first time, have been collected into a catalog. Production of the catalog suggests that gravitational wave... more
On Saturday, December 1, scientists attending the Gravitational Wave Physics and Astronomy Workshop in College Park, Maryland, presented new results from the... more
The twin LIGO (Laser Interferometer Gravitational-Wave Observatory) detectors, located in Livingston, Louisiana, and Hanford, Washington, and the Virgo detector located near Pisa, Italy, have... more
Four new detections of gravitational waves have been announced at the Gravitational Waves Physics and Astronomy Workshop, at the University of Maryland... more
Four new gravitational-wave observations mean scientists can start to make broader discoveries about the world around us and the black holes that fill it. more
The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical... more
An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun –... more
