![]() ![]() Since the inside of the cell is ordered and the outside is chaotic, there is an entropy gradient across the cell wall. Life on Earth uses a cell wall composed of a lipid membrane. Life that isn't harvesting negentropy isn't alive.įor life to exist it needs a barrier between its ordered self and its chaotic environment. This isn't a property life happens to have. They must harvest negentropy from an external source in order to stay alive. Living cells are at disequilibrium with their environment. The primordial soup theory is implausible from a physics perspective due to thermodynamics. The basic idea is that organic molecules (which just means chemical compounds with carbon-hydrogen bones) formed from natural physical processes and then some of those organic molecules randomly organized themselves into RNA and then that RNA built itself a cell. The most popular theory is called "primordial soup". But we don't know how the first cells formed out of nonliving matter. We know what happened after the first cells: evolution. We know what happened before biology―that's just physics. There is a singularity at the beginning of biology. ![]()
