Researchers believe dark matter could be composed of primordial black holes

Researchers from the Kavli Institute for the Physics and Mathematics of the Universe have been conducting a study of black holes that could’ve formed in the early universe. These so-called primordial black holes are believed to have formed before stars and galaxies were born. Primordial black holes could account for all or part of dark matter and be responsible for some of the observed gravitational wave signals and supermassive black holes found in the center of our galaxy and others.
The researchers also theorize the primordial black holes could play a role in the synthesis of heavy elements when they collide with neutron stars and destroy them, releasing neutron-rich material. The most interesting theory is that dark matter is composed of primordial black holes. Researchers looked at the early universe for clues about primordial black holes d

The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.
Such primordial black holes (PBHs) could account for all or part of dark matter, be responsible for some of the observed gravitational waves signals, and seed supermassive black holes found in the center of our Galaxy and other galaxies. They could also play a role in the synthesis of heavy elements when they collide with neutron stars and destroy them, releasing neutron-rich material. In particular, there is an exciting possibility that the mysterious dark matter, which accounts for most of the matter in the universe, is composed of primordial black holes. The 2020 Nobel Prize in physics was awarded to a theorist, Roger Penrose, and tw

Dark matter is thought to outnumber the regular stuff by a ratio of five to one, yet it remains frustratingly elusive. But there might be ways to potentially spot it, if you know where to look, and now astronomers have scanned neutron stars for telltale signals of a proposed dark matter particle called an axion.

In the 1970s, physicists uncovered a problem with the Standard Model of particle physics the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong interactions; the fourth is gravity). They found that, while the theory predicts that a symmetry between particles and forces in our Universe and a mirror version should be broken, the experiments say otherwise. This mismatch between theory and observations is dubbed “the Strong CP problem” CP stands for Charge+Parity. What is the CP problem, and why has it puzzled scientists for almost half a century?
