part 3 - K2-18 b Life Structure: How Life Can Exist Without Cells Under Extreme Pressure and Supercritical Water

Image
K2-18 b Life Structure Without Cells: Supercritical Water, Pressure, and Physical Stability K2-18 b as a pressure-shaped world where life may be understood as maintained physical structure. I live in South Korea and spend most of my time each day doing physical labor with my body. One day, as similar days kept repeating, I took a short moment to read observational data about K2-18 b, and I found myself stopping at one question. We often ask whether life exists on this planet, but in truth, under that extreme pressure and temperature, and within that unfamiliar chemical composition, we rarely think deeply about what kind of physical structure can actually remain without collapsing. From that moment, rather than imagining life in familiar forms, I began to follow, almost as a problem of its own, the question of “what can remain until the very end” within this environment. This writing was not made from imagination or storytelling, ...
