Dark matter: How primordial black holes could explain a long ... - CNN
Jun 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.
Black holes and dark matter — are they one and the same?
Dec 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 ...
Exotic black holes could be a byproduct of dark matter
Jun 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 …
Tiny black holes left over from the Big Bang may be prime dark matter ...
Apr 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...
New research challenges black holes as dark matter explanation
Jun 24, 2024 · A team of scientists from the OGLE (Optical Gravitational Lensing Experiment) survey from the Astronomical Observatory of the University of Warsaw have announced the results of nearly 20-year-long...
Primordial black holes are too scarce to explain dark matter
Aug 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...
Astronomers Find Early Fast-Feeding Black Hole Using NASA …
8 hours ago · Using data from NASA’s James Webb Space Telescope and Chandra X-ray Observatory, a team of astronomers have discovered this low-mass supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang. It is pulling in matter at a phenomenal rate — over 40 times the theoretical limit.
Scientists find first evidence that black holes are the source of dark ...
Feb 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 …
Dark Matter Black Holes Could Fly through the Solar System …
Sep 24, 2024 · Black holes the size of an atom that contain the mass of an asteroid may fly through the inner solar system about once a decade, scientists say. Theoretically created just after the big bang ...
Using gravitational waves to hunt for dark matter | The Royal ...
Attribution (CC BY 4.0) Using computer simulations, an international team of cosmologists have discovered that observations of gravitational waves from merging black holes may unveil the true nature of dark matter. Their findings are presented at the 2023 National Astronomy Meeting in Cardiff this week by co-author Dr Alex Jenkins of University ...
