Episode notes
Ship-As-First-Colony
- The first true interstellar colony will likely be the ship itself rather than a planet-side settlement.
- Long transit times force habitats to function as full, multi-generational cities during the voyage.
Decades-Long Journeys Are The Norm
- Realistic early interstellar speeds are decades-long, often a few percent of light speed, making trips measured in decades to centuries.
- That mandates habitats with full social, entertainment, and life-support systems for long-term continuity.
Mass Versus Energy Tradeoff
- A Stanford Torus habitat for 10,000 people might mass ~10–20 million tons, with fuel and propulsion dominating cost and difficulty.
- Power needs (lighting/agriculture) are large but trivial compared to the energy to move that mass between stars.
