How to Create a Black Hole Out of Thin Air

"How many ways are there to leave this universe? Perhaps the best known exit entails the death of a star. In 1939 the physicist J. Robert Oppenheimer and his student Harlan Snyder, of the University of California, Berkeley, predicted that when a sufficiently massive star runs out of thermonuclear fuel, it collapses inward and keeps collapsing forever, shrink-wrapping space, time and light around itself in what today is called a black hole. But it turns out that a dead star might not be needed to make a black hole. Instead, at least in the early universe, giant clouds of primordial gas may have collapsed directly into black holes, bypassing millions of years spent in stardom. ..."
