Episode notes
Silicon Life Needs New Genetics And Energy
- Silicon-based organisms would need alternative genetic polymers (s-DNA) and energy fluxes like thermocouples or photovoltaics.
- Evolution could favor quartz hides, photovoltaic tissues, or thermoelectric structures on molten or volcanic worlds.
Phosphorus As An Energetic Backbone
- Phosphorus sits between geology and biochemistry, storing energy in high-energy bonds and forming DNA backbones on Earth.
- Worlds rich in accessible phosphorus could evolve life centered on energy-rich phosphorus polymers and electrical conduction.
Crystals As Structural And Computational Media
- Crystals exhibit growth, repeatable lattices, and semiconductor properties making them plausible substrates for information processing.
- Life need not be wholly crystalline, but crystals can form skeletons, shells, or energy-harvesting tissues in alien ecologies.
