Summary:
- This article discusses the discovery of the largest black hole merger ever observed, which occurred about 7 billion years ago.
- The merger involved two black holes with masses about 85 and 66 times the mass of the Sun, resulting in a final black hole with a mass of about 142 solar masses.
- This discovery provides important insights into the formation and evolution of black holes, as well as the processes that can lead to such massive mergers in the distant universe.
