The question of the birthright of stars and black holes is a chicken-and-egg question. What came first? We are witnessing massive stars turning into black holes – it’s a proven fact. At the same time, we are also focusing on the existence of supermassive black holes in the early universe that would not have had time to reach detectable mass. “James Webb” seems ready to solve this mystery. Astrophysical Journal Letters reports that a group of scientists from Johns Hopkins University in the US and Sorbonne University in France have collected web data on black holes discovered in the early universe, providing further evidence for the hypothesis that stars were born at the same time. Scientists realized that Webb discovered a supermassive black hole 470 million years after the Big Bang, and even 400 million years later. The mass of the latter was determined to be 1.6 million suns. She was at the center of a galaxy that was lighter than the hole in its center. A black hole with such a mass cannot grow to a certain value. According to our observations, black holes are formed by the collapse of dying stars with more than 50 solar masses. This could not have happened in the early Universe, leading to the effect observed there: small galaxies clustered around a black hole. The researchers conclude that primordial black holes formed from clouds of primordial material at the same time as the first stars, or slightly earlier. The centers of the clouds collapsed, and the black holes that appeared in each cloud began to emit winds, which triggered and accelerated the process of star formation. In fact, primordial black holes became the tools for assembling galaxies and transforming them into the structures we observe. “We argue that jets of gas depart from clouds of black holes and transform them into stars, significantly accelerating the rate of star formation,” the paper’s authors said. “We can’t see these strong winds or jets very far away, but we know they must exist because we see many black holes in the early stages of the universe.”
