Death as a First-Order Depletion Process: The Aging Equation of the Carbon-Based Power Grid and the Boundaries of Longevity

This paper proposes a first-order depletion kinetics model of aging grounded in the physical principles of Neutralization Destiny and Electrochemical Lift. At the heart of the model is the death equation: the cumulative net charge leakage over time eventually exhausts the system's insulation budget, forcing the system to collapse. Aging is thus reduced to a single measurable physical process—the continuous leakage of charge from the body's electrochemical network—while death is the inevitable thermodynamic relaxation that occurs when insulation is depleted below a critical threshold. This paper provides, for the first time, a unified physical foundation for mainstream aging theories—free radical damage, telomere attrition, mitochondrial dysfunction, and epigenetic drift—by demonstrating that the damage accumulation processes described by these theories may share a single underlying driver: the progressive electrical leakage of the carbon-based power grid and the energy budget constraint of the repair system. From the death equation, the paper derives four testable predictions: the mathematical impossibility of immortality, a negative correlation between body size and lifespan, a calculable development-repair inflection point, and a unique potential advantage of the umbilical charging pathway that bypasses hepatic first-pass metabolism. This paper is a purely conceptual hypothesis containing no new experimental data, but it provides a complete mathematical model and a parameter extraction roadmap for independent verification.
