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.

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 mergers involved either two black holes or two neutron stars. In 2021, ...

Black holes are among the most enigmatic and fascinating objects in the universe. Their sheer existence challenges our understanding of the cosmos and raises deep questions about the nature of reality ...

The Laser Interferometer Gravitational-wave Observatory (LIGO) achieved a historic milestone by making the first direct detection of gravitational waves in 2015. It originated from a black hole merger ...
