Gravitational wave hunters will get an ultracool new tool in 2023
31 December 2022
We have been detecting gravitational waves since 2015, but there is still much more to learn. The Matter-wave Laser Interferometric Gravitation Antenna will use ultracold atoms to spot ripples in space-time at lower frequencies than ever before
How a new kind of gravitational wave will reveal the early universe
16 March 2022
With 90 detections now under our belt, gravitational waves are solving riddles about the evolution of galaxies and missing black holes – and they could soon give us a glimpse of dark matter
Quantum nature of gravity may be detectable with gravitational waves
30 August 2021
Perhaps the most important problem in physics is how gravity and quantum mechanics fit together, and strange fluctuations in gravitational waves could help us figure it out

Dark matter must exist, but has evaded all attempts to find it. Now comes our boldest plan yet – sensing its minuscule gravitational force as it brushes past us
Some physicists still doubt whether LIGO has seen gravitational waves
10 September 2019
LIGO has explained how it processes gravitational wave data in greater detail than ever before. But some physicists still say the analysis contains mistakes
Welcome to the 5th dimension: Our universe's radical new fate
17 July 2019
Our best models of cosmology suggest the universe will either go on forever, implode or rip itself apart. A new proposal suggests an even weirder destiny
