David joins Hakeem to discuss primordial black holes, tiny objects that may have formed in the first fraction of a second after the Big Bang. First proposed by Stephen Hawking more than 50 years ago, this hypothesis requires no new physics and no new particles, making it one of the most grounded ideas currently on the table… and one that may solve more than one cosmic mystery. David explains what these primordial black holes are, why many in the physics community are returning to this decades-old idea, and how it could potentially solve the dark matter mystery.
