Scientists may have found an answer to the mystery of dark matter. It involves an unexpected byproduct
Scientists studying the earliest black holes may have found an answer to dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight.
Early in the search, renowned British physicist Stephen Hawking postulated that dark matter could be hiding in black holes — the main subject of his work — formed during the big bang. The study, published June 6 in the journal Physical Review Letters, reveals that these black holes must have appeared in the first quintillionth of a second of the big bang: “That is really early, and a lot earlier than the moment when protons and neutrons, the particles everything is made of, were formed,” Alonso-Monsalve said. These minuscule black holes, due to their small size, would have been able to pick up a rare and exotic property from the quark-gluon soup in which they formed, called a “color charge.” It is a state of charge that is exclusive to quarks and gluons, never found in ordinary objects, Kaiser said.
