Prebiotic Geochemical Automata at the Intersection of Radiolytic Chemistry, Physical Complexity, and Systems Biology

Figure 5

An approximated temperature feedback control diagram of a natural ²³⁵U water-moderated and cooled fission zone. Thermostatic feedback is an emergent property spread between subatomic, atomic, and molecular levels of energy attenuation. The maximum temperature of the thermostat is governed by the boiling temperature of the moderating fluid, which is most likely water but may also include organic carbon compounds produced via radiolysis of inorganic carbon.
