Three scientists from the U.S. Department of Energy's Brookhaven National Laboratory have determined one plausible theory to explain the formation of supermassive black holes, and the key is ultralight dark matter
But known particles wouldn't behave quite right under those conditions to form supermassive black holes. So the researchers hypothesized an as-of-yet-unobserved form of matter — ultralight dark matter, which would be 28 times lighter than a proton at the heart of an atom — might be the key to the process.
"The frequency of interactions between known particles suggests matter, as we know it, would not have collapsed into black holes very efficiently," Denton said."But, if there was a dark sector with ultralight dark matter, the early universe might have had just the right conditions for a very efficient form of collapse.
But supermassive black holes, which have millions or billions of times more mass than regular black holes, are much too large to form by those means, since scientists believe the behemoths formed very early in our universe's history, which wouldn't give them enough time to acquire so much mass. But the Brookhaven team's model of a collapse of ultralight dark matter provides a potential explanation — and a signal to look for.
