In simple terms, the model suggests that supermassive black holes are "very, very fast over very, very short periods of time" and then suddenly come to a standstill. "Supermassive black holes only had a short time to grow quickly, and then their production eventually came to a halt due to all the radiation in the universe created by other black holes and stars," Basu said. So far, the current understanding has been that black holes form star masses when the center of a massive star collapses. By contrast, Basu and Das propose that some black holes come from direct collapse rather than star remnants.
According to the researchers, over the last decade many supermassive black holes have been discovered that are billions of times heavier than the Sun. Scientists believe that they formed within 800 million years after the Big Bang, but this challenges our understanding of the formation and growth of black holes. This new direct collapse scenario could explain the emergence of these early supermassive black holes.
