The Physical Necessity of Life: A Unified Derivation from Vesicles to Civilization

Modern life sciences have accumulated immense knowledge describing how life works, yet the question of physical necessity—why life must be the way it is rather than otherwise—has remained largely unasked. This paper presents a unified physical derivation of life phenomena proceeding from three known physical laws: the second law of thermodynamics, Newton's first law, and Ohm's law. Operating simultaneously on carbon-based carriers, these laws necessarily produce the complete spectrum of life phenomena—from primitive vesicles to DNA, from the geometric predetermination of the heart to the passive shaping of the brain, from the mathematical inevitability of aging to the universal physical conditions for extraterrestrial life. The Life Force Equation and the Type I/Type II memory phase transition are proposed as unifying conceptual frameworks. This derivation does not replace existing biological knowledge—it provides the physical substrate for it. All core deductions are accompanied by specific falsification conditions.
