Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of ...

A new data release more than doubles the number of gravitational-wave candidate events—and reveals unexpected complexities of merging black holes ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

The results are included in a new paper from the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the VIRGO gravitational-wave detector, which presents analysis of 10 stellar-mass binary ...

To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB. There’s a new cosmological background in town. In June, researchers from the ...

In a paper published Nov. 7th on the preprint server ArXiv, the team has detected a further 35 gravitational wave events since the last catalog release in October 2020, bringing to 90 the total number ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By transferring minute amounts of energy between light and gravity, the interaction ...

Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe’s gravitational wave background. That’s the name for the ripples in space and time that move ...

Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of general relativity to its toughest test yet. This extraordinary signal, known as ...
