Massive black hole found napping after overeating raises eyebrows

In a remarkable discovery, an international team of astronomers led by the University of Cambridge identified a massive black hole in the early universe, located just 800 million years after the Big Bang. The discovery, made with the advanced capabilities of the NASA/ESA/CSA James Webb Space Telescope, revealed that this black hole has a mass 400 million times that of the Sun and is currently in a dormant state after a period of rapid growth. Typically, black holes are believed to consist of about 40 percent of the mass of their host galaxies, while most are significantly smaller. This finding challenges existing models regarding how black holes evolve, as most are thought to maintain a mass of around 0.1 percent of their host.
