A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics ...

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.

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

It took less than a second for the space observatory hidden in Louisiana woods to detect a black hole that is that is ...

Named GW 231123 after the date it was recorded on 23 November 2023, it's the most massive black hole collision we've seen yet ...

The biggest black hole merger yet observed could confirm a rare class of black holes long thought to be missing from the universe.

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, ...

Caption: Astronomers have revealed the largest black hole merger to date. This illustration shows how the merger would appear to our eyes if we could somehow travel in a spaceship for a closer look.
