Resumen de Extreme gusts of space gas fed big black holes
Shingo Hirano at the University of Texas at Austin and his colleagues simulated conditions in the early cosmos to figure out how the seed holes might be born. In their model, a halo of dark matter was blasted by supersonic gas streams in the chaos of the big bang. The dark matter's gravity captured some of the gas, forming a dense cloud. Normally, such a cloud would fragment, collapsing in several places and turning into many stars. But the team found that turbulence introduced by the streaming motion delayed this. Eventually, this meant the gas cloud got big enough to collapse in on itself, rapidly building a star thousands of times more massive than the sun. That object ended up as a black hole 2 billion times the mass of the sun, and it did so less than 800 million years after the big bang--much faster than the way black holes grow today
