Black holes this massive are forbidden through standard stellar evolution models.” And with those words, Cardiff University’s Mark Hannam, a member of the LIGO-Virgo-KAGRA (LVK) Collaboration, ...

Our galaxy may reside in a billion-light-year-wide cosmic bubble that accelerates local expansion, potentially settling the ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely ...

“It’s the most massive [merger] so far,” says Mark Hannam, a physicist at Cardiff University, UK, and part of the LVK ...

Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

New gravitational wave findings from the LIGO-Virgo-KAGRA Collaboration report the discovery of the largest black hole merger ...

Scientists have witnessed evidence of a collision between black holes so huge that it defies their understanding of physics.

To date, the collaboration has detected dozens of merger events since its first Nobel Prize-winning discovery. Early detected ...

Though our solar system and the movement of its planets appear relatively sedate, there are many things that could upset the ...
