Astronomers have detected the most massive black hole merger ever observed, challenging stellar evolution and black hole formation theories.

The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

A collision observed between two black holes, each more massive than a hundred suns, is the largest merger of its kind ever ...

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

Two colossal black holes—among the most massive ever seen—collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

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

Ripples in space-time signalling the largest merger of two black holes ever seen challenge current understanding of the ...

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

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

The Laser Interferometer Gravitational-wave Observatory (LIGO) is no stranger to making history and breaking records. In 2015 ...

The Trump administration has proposed closing either the LIGO Hanford observatory in WA or its twin in Louisiana.

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