Between May 2023 and January 2024, a global network of gravitational-wave detectors picked up 128 new cosmic signals, more ...

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

A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of ...

Researchers have designed a new type of gravitational wave detector that operates in the milli-Hertz range, a region untouched by current observatories. Built with optical resonators and atomic clocks ...

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 ...

LIGO's 2015 detection confirmed Einstein's theory and sparked a decade of data. Upgraded LIGOs now detect black hole mergers every three days with precision. New 2025 findings confirmed Hawking’s ...

The younger black hole, the product of a cataclysmic cosmic event known as a black hole merger, was first spotted in 2019. Now, about 6 years later, a team of international researchers led by the ...

Scientists have used the loudest gravitational-wave signal ever recorded to put Albert Einstein's more than 100-year-old theory of gravity to its toughest test yet — and once again, it passed. The ...

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 ...

Simon Stevenson receives funding from the Australian Research Council. He works for Swinburne University of Technology. He is a member of OzGrav and the LIGO Scientific collaboration. Ten years ago, ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...
