A new study from the Australian National University (ANU) shows that the fastest-growing black hole in the universe has a mass that grows in one day equivalent to the mass of a sun. The study, carried out by Dr Christopher Onken of the Australian National University and colleagues, found that the fastest-growing black hole was about 34 billion times the mass of the sun and about 8,000 times the mass of the Milky Way black hole. Its daily growth is equivalent to the mass of a sun.
“This supermassive black hole, called J2157, was discovered in 2018 and was formed about 1.2 billion years into the universe and is the largest black hole in the early universe,” Dr. Onken said. If the Milky Way’s black holes are to reach this mass, they must devour about two-thirds of the stars in the Milky Way. “
At present, researchers don’t know exactly how the black hole became so large in the early universe, and they are looking for more black holes through the European Southern Observatory (ESO) to see if they can bring some clues.
The researchers point out that how much black holes can swallow depends on the size of their mass, and at the current rate of devouring, we think it is expected to become the largest black hole in the universe.
