What If A Black Hole Dwelt Inside The Sun? | Hawking Stars

Oct 29, 2026 · 23m

Summary

This episode explores the theoretical possibility that stars harbor primordial black holes, a concept first suggested by Stephen Hawking. It details how such "Hawking stars" would evolve, potentially mimicking red giants before being consumed from the inside out. The discussion highlights new simulations and astroseismology methods that could detect these hidden black holes, offering a unique way to test if primordial black holes constitute dark matter.
