Dark matter could have helped make supermassive black holes in the early universe
It takes a long time for supermassive black holes, like the one at the center of our Milky Way galaxy, to form. Typically, the birth of a black hole requires a giant star with the mass of at least 50 of our suns to burn out - a process that can take a billion years - and its core to collapse in on itself. Even so, at only about 10 solar masses, the resulting black hole is a far cry from th
