Crystalline Alien Civilizations

Crystalline alien civilizations are one of the oldest and strangest models in alien-civilization theory: societies built not from soft carbon-based tissues, but from ordered lattices, mineral growth systems, or crystal-like bodies that persist through pattern rather than flesh. Drawing on crystallography, Cairns-Smith’s crystal-gene hypothesis, mineral self-organization research, and the long science-fiction history of inorganic aliens, the concept explores whether civilization could ever emerge from matter that seems more geological than biological.
