A model for a non-chemical form of life: Crystalline physiology
- to be stable,
- to contain rich information,
- to diffuse it into the surrounding medium.
It is then shown that the complex dislocation networks encountered in crystals can in some cases follow these criteria and lead to a crystalline physiology. The places of possible occurrence in nature of this kind of physiology, terrestrial and extraterrestrial rocks, interplanetary dust, white dwarfs and neutron stars are then discussed.
