It took 13 billion years, but light from the first black holes in the universe is finally reaching our telescopes. And now that we can see the light, we now know more about how these distant space phenomena formed, a new study suggests. “In this study, we have uncovered a totally new mechanism that sparks the formation of massive black holes,” study lead author John Wise, an astrophysicist at Georgia Tech, said in a statement.That new mechanism is the rapid growth of “halos” of dark matter, the mysterious stuff that makes up most of the material universe (and is so named because it neither absorbs nor reflects light), according to Space.com.”Instead of just considering radiation, we need to look at how quickly the halos grow,” Wise added. “We don’t need that much physics to understand it – just how the dark matter is distributed and how gravity will affect that. Forming a massive black hole requires being in a rare region with an intense convergence of matter.”Wise and his colleagues came to this conclusion after analyzing supercomputer simulations of the early universe’s evolution, Space.com reported.The researchers said that when galaxies form quickly, very massive black holes can form. In those rare galaxies, normal star formation is disrupted and black hole formation takes over.
