In a video for PBS Nova, alumna Elba Alonso-Monsalve PhD ‘26 explains the definition of primordial black holes (PBHs), and how dark matter may be formed from them. “Think like the mass of an asteroid but packed into the volume of a single atom, and these [PBHs] would be floating around our universe, maybe even our own solar system,” says Alonso-Monsalve. “There could be enough of these PBHs lurking around to make up all of the dark matter, and they would be tiny enough to be hard to spot.”
