Death by Black Hole
Summary
This episode explores the mechanics of black holes, explaining how massive stars collapse into singularities with gravity so intense that not even light can escape. The narrator contrasts these cosmic threats with other extinction scenarios before detailing the formation process, including the role of iron fusion and the event horizon. A central segment imagines a hypothetical journey into a black hole, describing the visual distortion of the universe and the CMB as one approaches the horizon. The discussion concludes by explaining why escape is impossible, noting that inside the event hori…
