Episode notes
Doomsday Evolved Beyond Nukes
- Doomsday concepts evolved from nuclear fears into imaginative weapons that erase reality itself.
- Science fiction stretches apocalypse from firepower to things that unmake time, causality, and meaning.
Project Sundial And Nuclear Fears
- Project Sundial and Cold War stockpiles pushed the idea that humans could cause civilization-ending disasters.
- Isaac Arthur notes these fears made extinction seem achievable and reshaped fiction and policy.
Scale Replaces Mystery In Cosmic Arms
- Cosmic-scale weapons use star or black-hole energy to annihilate planets or fleets rather than violate physics.
- These are extreme extrapolations of known physics, not necessarily science fiction magic.
