Scientists at the world's largest gravitational wave observatory have just squeezed light beyond a key quantum limit. The new technique, called frequency-dependent squeezing, will increase the number ...

The alerts started in the early morning of Aug. 17. Gravitational waves produced by the wreck of two neutron stars—dense cores of dead stars—had washed over Earth. The thousand-plus physicists of the ...

Call it a gut reaction. The revolutionary discovery of space-time ripples may have come from two black holes colliding while inside the belly of an enormous star, whose subsequent collapse launched ...

RICHLAND, Wash. Just a short distance from where this nation once made plutonium for nuclear warheads, scientists believe they are close to making history by detecting for the first time a phenomenon ...

This week’s landmark discovery of gravitational and light waves generated by the collision of two neutron stars eons ago was made possible by a signal verification and analysis performed by Comet, an ...

PORTLAND, Ore. — One of the biggest discoveries in modern physics came as a quiet thump in the night. The first ever detection of a gravitational wave sent ripples of excitement through the scientific ...

Today the Barcelona Supercomputing Center announced it has allocated 20 million processor hours to the LIGO project, the most recent winner of the Nobel Prize for Physics. Since 2015, the LiGO project ...

Scientists reveal how two giant laser interferometers in the US have been able to ‘hear’ gravitational waves produced by the collision of two black holes. Scientists at the two Laser Interferometer ...

When incredibly massive objects collide violently in space, they send out ripples in space-time that reverberate through the cosmos for billions of years. Long after the collisions happen, these ...

The core of a neutron star is such an extreme environment that physicists can’t agree on what happens inside. But a new space-based experiment — and a few more colliding neutron stars — should reveal ...
