Neutron Stars Collide in New LIGO Signal?
Summary
This episode explores the rumored LIGO detection of a neutron star merger, analyzing evidence from gamma-ray bursts and Hubble observations to confirm the event. The hosts explain the physics of neutron stars, why they are harder to detect than black holes, and how such collisions may produce heavy elements like gold. The segment concludes with answers to viewer questions about stopping hurricanes with nuclear weapons, observing Proxima Centauri b, and the mathematical similarities between the Big Bang and white holes.
