Episode notes
Freezing Beats Running Life Support
- Cryogenic arks trade continuous life support for passive preservation to vastly reduce energy and entropy demands.
- Isaac Arthur explains freezing people reduces a ship from a city to an insulated vault, easing long-duration travel constraints.
Vitrify To Avoid Ice-Shrapnel
- Vitrification and cryoprotectants aim to prevent ice crystal damage by making tissues glass-like rather than frozen solid.
- Isaac Arthur notes current success with embryos and organs, but whole-body revival remains unsolved today.
Nature's Frozen Survivors
- Isaac Arthur cites the wood frog, Antarctic fish, and tardigrade as natural examples of suspended animation strategies.
- These examples show evolution already solved many suspended animation problems at small scales.
