Fresh observations of two merging black holes confirm predictions made by Stephen Hawking based on Albert Einstein’s theory. A decade after the first detection of gravitational waves from two merging ...
In the world of astrophysics, Stephen Hawking’s predictions about black holes have always sparked fascination and debate. Recent data from the LIGO-Virgo-KAGRA collaboration has provided the clearest ...
The international LIGO-Virgo-KAGRA Collaboration has completed the fourth observation campaign (called O4) of the ...
When two massive objects – like black holes or neutron stars – merge, they warp space and time. Mark Garlick/Science Photo Library via Getty Images After a three-year hiatus, scientists in the U.S.
On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever ...
After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light ...
Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...
It has been three years since the Laser Interferometer Gravitational-Wave Observatory (LIGO) shut down, starting a long hiatus from searching the universe for gravitational waves. Now, though, the ...
Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

Physicist who won a Nobel Prize for LIGO Hanford observatory in Eastern WA died. LIGO confirmed Einstein’s theory of relativity by detecting gravitational waves in 2015. Twin LIGO sites in WA and LA ...
Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO. In 2015, ...
