The Library of Existence: Dark Matter as a Thermodynamic Archive

This work introduces the Library of Existence, a unified theoretical framework that reinterprets the universe as a thermodynamic accounting system in which all irreversible processes are permanently archived. Within this model, dark matter is identified not as undiscovered particulate matter, but as the gravitationally active, electromagnetically silent archive of completed energy transactions. Each irreversible physical or biological process is treated as a transaction (“Verb”) that, upon completion, is finalized by entropy and compressed to its maximal information density. This compressed record—termed a Binary-Wrapped Transaction—possesses mass via mass–energy–information equivalence and couples only gravitationally to spacetime. The accumulated ensemble of such records constitutes the dark matter component of the universe. Galactic dark matter halos are therefore reinterpreted as spatial maps of historical energetic activity rather than anomalies requiring new particle species. At biological scales, the framework reframes stress, aging, and disease as manifestations of archival inefficiency—situations in which transactions require excess entropy to be encoded. Observable phenomena such as oxidative stress, thermal dissipation, circadian desynchrony, and cognitive fatigue are interpreted as measurable indicators of ledger imbalance rather than primary mechanical failures. To formalize this, the paper introduces the Ledger Health Index (LHI), a scalar metric quantifying entropy overhead relative to expected informational cost. By bridging cosmology, thermodynamics, and systems biology, this work presents a single forensic accounting paradigm in which gravity serves as the read-only interface of the universe’s memory, entropy acts as the settlement mechanism, and dark matter represents the cumulative weight of recorded history. The framework offers conceptual unification, reinterpretation of existing observations, and a basis for future testable predictions across astrophysical and biological domains.
