Dark matter: How primordial black holes could explain a long ... - CNN
WEBJun 17, 2024 · Scientists studying the earliest black holes may have found an explanation for dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight.
Exotic black holes could be a byproduct of dark matter
WEBJun 6, 2024 · In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain all the dark matter that we can’t see today.
Black holes and dark matter — are they one and the same?
WEBDec 16, 2021 · A new study theorizes that primordial black holes formed after the Big Bang (the far left panel) constitute all dark matter in the universe. At early epochs they cluster and seed the formation of early galaxies and then eventually grow by feeding off gas and merging with other black holes to create the supermassive black holes seen at the ...

WEBFeb 15, 2023 · Observations of supermassive black holes at the centers of galaxies point to a likely source of dark energy—the 'missing' 70% of the universe.
Tiny black holes left over from the Big Bang may be prime dark matter ...
WEBApr 13, 2024 · Don't rule out primordial black holes as dark matter suspects just yet! Particle-sized black holes may resist evaporation, surviving long enough to account for the universe's most...
A wobble from Mars could be sign of dark matter, new study finds
WEBSep 17, 2024 · New simulations suggest that there are enough primordial black holes—potential dark matter candidates—in the universe for one to pass through the inner solar system every decade. The work builds upon an astrophysical theory that has growing popularity.
Primordial black holes are too scarce to explain dark matter
WEBAug 19, 2024 · A decades-long survey of a nearby galaxy has detected signals consistent with ancient black holes that could explain dark matter — but the objects would have to be at least ten times more...

WEBFeb 15, 2023 · Black holes can increase in size by accreting matter, such as by swallowing stars that get too close, or by merging with other black holes. To discover whether these effects alone could account for the growth of supermassive black holes, the team looked at data spanning nine billion years.
