The Real Star Wars
Summary
This episode explores the militarization of space during the Cold War, detailing the development of ICBMs, the Soviet Almaz spy stations, and the US Strategic Defense Initiative. The host explains the physics behind the Excalibur program’s nuclear-powered X-ray lasers and the subsequent Brilliant Pebbles kinetic weapon concept, noting their cancellation due to technical and treaty violations. The discussion concludes with modern anti-satellite missile tests and the risks of orbital debris, followed by brief answers to listener questions regarding electron mass and quantum scattering.
