How Many Black Holes Reside In The Solar System?
Sep 14, 2026 · 27m
Summary
This episode explores the possibility that dark matter consists of asteroid-mass primordial black holes formed shortly after the Big Bang. The hosts explain that while these objects are invisible, their gravitational pull would cause minute, detectable deviations in planetary orbits. By using precise laser ranging to Mars and advanced simulations, scientists can distinguish these subtle shifts from the background noise of known asteroids. This approach effectively turns the entire solar system into a giant detector, potentially solving the dark matter mystery without needing new particle co…
