David Kaiser: MIT Physicist on Black Holes Older Than the Universe

MIT physicist and historian David Kaiser examines primordial black holes, exploring how they might explain dark matter and connect to cosmic inflation. He discusses their potential impact on our understanding of the early universe, linking quantum theory, cosmology, and the history of physics.
