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 ...

The universe is a turbulent place. Stars are exploding, neutron stars collide, and supermassive black holes are merging. All of these things and many more create gravitational waves. As a result, the ...

The universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. It’s no small feat to measure the ...

An international study led by astronomers from Swinburne University of Technology has created the most detailed maps of gravitational waves across the universe to date. The study has also produced the ...

For more than a decade, astronomers quietly watched the most precise clocks in the cosmos, waiting for a barely perceptible shiver in spacetime. Now, after 15 years of patient measurement, they say ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the ...

Cosmic domain walls are two-dimensional topological defects that arise when a discrete symmetry is broken in the early Universe. As networks of these walls evolve and eventually annihilate, they emit ...

Researchers have built a quantum sensor prototype that cancels laser phase noise, advancing atom interferometry for cosmic ...

Using the largest gravitational wave detector ever made, we have confirmed earlier reports that the fabric of the universe is constantly vibrating. This background rumble is likely caused by ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational waves. University of ...

Pulsar timing arrays exploit the extraordinary rotational stability of millisecond pulsars as a network of galactic clocks. By precisely measuring the arrival times of radio pulses over years to ...
