Groundbreaking Black Hole Merger Challenges Cosmic Understanding

11/20/2025

Summary

Story summary

The gravitational-wave event GW231123 marks the most significant merger ever detected, forming a "forbidden" black hole.
The merger involved black holes weighing about 100 and 130 solar masses, placing them in the mass gap.
The study suggests rapidly spinning, magnetized stars can collapse in unexpected ways, enabling more efficient black hole formation.
These findings challenge existing models and could reshape our understanding of cosmic history and supermassive black holes.
