A significant astronomical discovery involves the merger of two black holes, creating a composite with over 225 times the mass of the Sun. Detected via gravitational waves, the signal termed GW231123 originated from a distance of 2 to 13 billion light-years. These black holes also exhibit extreme spinning speeds, approximately 400,000 times the Earth's rotation, which raises questions about black hole formation theories. Traditional models do not allow for such massive black holes, indicating possible formation through prior smaller black hole mergers. This event poses challenges to existing gravitational-wave detection technology and theoretical understanding.
The most massive black hole binary observed through gravitational waves is an enormous black hole over 225 times the mass of our Sun, a significant discovery.
Detected by the LIGO observatories, the black hole merger signal GW231123 comes from between two and 13 billion light-years away, posing challenges to current theoretical models.
The rapid spin of the black holes, around 400,000 times that of Earth's rotation speed, challenges both gravitational-wave detection technology and existing models of black hole formation.
Experts suggest the formation of such massive black holes might be linked to earlier mergers of smaller black holes, as traditional stellar evolution models do not account for them.
