Cocoons of debris around dying stars could shake ripples in spacetime unlike any astronomers have ever seen. “This is a potential source of gravitational waves that has never been investigated before, ...

Observations of gravitational waves from merging black holes may unveil the true nature of dark matter, according to new research. The announcement last week of the discovery of the gravitational wave ...

There’s a big debate in cosmology about how fast the universe is currently expanding. The collision of two neutron stars in 2017, seen in an artist's rendering, created both gravitational waves and ...

The universe is humming with gravitational radiation — a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. That is the conclusion of several ...

LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves ...

Until now, we’ve only detected gravitational waves originating in binary systems, from the merger of black holes or neutron stars. But researchers from Northwestern University have potentially ...

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the ...

It now takes just a fraction of a minute to detect neutron star mergers, thanks to advancements in a machine-learning-driven approach to astronomy. Reading time 3 minutes A team of researchers just ...

A new simulation by NASA astronomers provides a unique perspective of the cosmos through the lens of gravitational waves, which are elusive ripples in the fabric of space-time generated by orbiting ...
