Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new ...
The findings confirm the presence of rare binary systems and suggest certain black holes are second-generation, forged in earlier cosmic collisions.
The Laser Interferometer Gravitational Wave Observatory (LIGO) has seen over 300 black hole mergers in its short time in operation, and now it’s seen an event so large—and so rare—that it challenges ...
