What are the three primary interacting domains necessary for life to continue across geological timescales?
Answer
Location relative to the parent star, the planet’s intrinsic protective mechanisms, and the availability of necessary chemical scaffolding.
The requirements for life to persist over geological timescales coalesce into three primary interacting domains: the location relative to the star (Stellar Distance), the planet’s internal shielding capabilities (Planetary Shielding), and the presence and cycling of necessary chemical components (Geochemistry and Energy).
