Hypothetical black holes formed in the very early universe, potentially before the formation of stars and galaxies, could possess a property analogous to electric charge, but related to the strong nuclear force. This “color charge,” a characteristic of quarks and gluons described by quantum chromodynamics (QCD), could significantly influence these early-universe objects’ interactions and evolution. Unlike stellar-mass black holes formed from collapsing stars, these objects could have a wide range of masses, possibly even smaller than a single atom.
The existence of such objects could have profound implications for our understanding of the early universe, dark matter, and the evolution of cosmic structures. These small, charged black holes might have played a role in the formation of larger structures, served as seeds for galaxy formation, or even constitute a portion of dark matter. Their potential discovery would offer valuable insights into the conditions of the early universe and the nature of fundamental forces. Investigating these hypothetical objects can also shed light on the interplay between general relativity and quantum field theory, two cornerstones of modern physics that are notoriously difficult to reconcile.
