A yet-unseen population of ancient black holes may be lurking throughout the universe. If they exist, these bottomless cosmic pits would have a lot in common with known types of black holes. But unlike known black holes, the mysterious kind would have formed right after the Big Bang — before stars and galaxies even existed. Such early-blooming black holes would be primordial black holes. Scientists have wondered for decades if such exotic objects exist.

The icon indicates free access to the linked research on JSTOR. For millions of years following the Big Bang, after the universe’s roiling soup of particles had cooled, the cosmos was a dark and boring place. There were no stars to make light. No familiar swirls of galaxies. Certainly no planets. And the entire universe was shrouded in neutral hydrogen gas. Then, perhaps 100 million years or so in, everything started to change.

An undiscovered population of ancient black holes may be lurking throughout the universe. These bottomless cosmic pits would have a lot in common with more familiar black holes; in some cases, the two may be indistinguishable. But unlike their kin, these undiscovered black holes wouldn’t have formed from a massive star collapsing in on itself, nor would they be peers of the supermassive black holes that feed at the centers of galaxies.

For more than two decades, Theresa S. Betancourt has followed the lives of children (now adults) who returned home after being forced to fight in the civil war that ravaged Sierra Leone from 1991 to 2002. Thousands of children unwillingly participated in the violent conflict as soldiers, spies and laborers. Many took part in attacks on their own neighbors and relatives, many faced sexual violence, many witnessed unspeakable atrocities.

For millions of years following the Big Bang, after the universe’s roiling soup of particles had cooled, the cosmos was a dark and boring place. There were no stars to make light. No familiar swirls of galaxies. Certainly no planets. And the entire universe was shrouded in neutral hydrogen gas. Then, perhaps 100 million years or so in, everything started to change. Over the next billion-odd years, the universe went from a bland, unimpressive landscape to a rich and dynamic one.
