MIT Scientist's Discovery: "Black Holes Might Be Dark Matter!"

Primordial black holes represent a compelling, albeit hypothetical, cosmological phenomenon that could potentially resolve long-standing mysteries, including the nature of dark matter and the origin of supermassive black holes. Unlike stellar-collapse black holes, these entities would have formed directly from early-universe density fluctuations, long before the emergence of stars. David Kaiser, a theoretical physicist and historian of science, highlights how these black holes serve as a central node connecting disparate fields, from quantum field theory and QCD plasma dynamics to solar system orbital mechanics. By leveraging high-precision astronomical data and multi-field inflationary models, researchers can test these theories without the extreme fine-tuning required by simpler models. Furthermore, the search for these objects involves innovative techniques, such as analyzing gravitational perturbations in the solar system and investigating high-energy neutrino events, bridging theoretical cosmology with observational astrophysics.
