A distant black hole is 10 times smaller than thought, upending early universe black hole growth theories.
Astronomers using the GRAVITY+ instrument at the European Southern Observatory have found a supermassive black hole in a 12-billion-light-year-away quasar to be about 10 times smaller than previously estimated, challenging long-standing theories about early universe black hole growth.
The discovery, based on observations of intense radiation expelling surrounding gas—a "cosmic hairdryer" effect—suggests earlier mass estimates were inflated due to flawed measurement methods.
This finding may require a reevaluation of models for black hole formation and galaxy evolution in the universe’s first billion years.
