MP3•Episode home

In this episode of Theories of Everything, MIT physicist and historian David Kaiser explores primordial black holes which are hypothetical entities that may have formed before stars or atoms. David discusses their potential role in explaining dark matter, their connections to cosmic inflation, and how they might reshape our understanding of the early universe. This conversation connects the realms of quantum theory, cosmology, and the history of physics. As a listener of TOE you can get a special 20% off discount to The Economist and all it has to offer!
