K2-18 b Life Structure Without Cells: Supercritical Water, Pressure, and Physical Stability This article examines K2-18 b through pressure, temperature, supercritical water, chemical gradients, and physical stability. It does not claim that life has been found, but asks what kind of structure could remain when Earth-like cells and membranes may fail. PASTE YOUR FULL ENGLISH ORIGINAL TEXT HERE. DO NOT PUT IMAGE CODE INSIDE THIS PRE BLOCK. Summary Table Theme Core Idea Planetary Environment K2-18 b is analyzed through pressure, temperature, chemical composition, and water-state conditions. Life Constraint Earth-type cells, membranes, proteins, and enzymes may not remain stable under extreme conditions. Alternative Structures Life-like systems may emerge as density layers, reaction networks, chemical patterns, or slow information structures. Energy Source Chemical gradients and redox imbalances may be more important than sunligh...
