Version 3.10 FE: Phase Transition: Dark Energy → Fundamental Energy + Residues v2.7 was skipped. The jump to v3.0 reflects what actually changed. The reversible/irreversible OM distinction is now explicit, and the FM exit and entropic settlement - higher floor - mechanisms are formalized. Part I remains as established: the reclassification of dark matter and dark energy, the resolution of the cosmological constant problem, and the trans-generational conservation of FM and FE. Part II is new: the terminal universe, the chorus trigger, and a proposed mechanism for the Big Bang itself. Not a singularity from nothing — a phase transition with a cause. Although further validation is required: Λ Problem → Boundary Condition Solution α Problem → Self‑Referential Equation Solution Abstract Part I We call it dark matter because we cannot see it, and dark energy becausewe do not understand it. Both names reflect our limitations rather than thenature of the things themselves. This paper proposes that what isconventionally termed dark matter is more precisely Fundamental Matter(FM) — the basic form of matter, interacting solely through gravity — andthat what is conventionally termed dark energy is more preciselyFundamental Energy (FE) — the basic expansive property of space,symmetric to gravity.We propose that what is conventionally termed dark matter is moreprecisely Fundamental Matter (FM) — the basic form of matter, interactingsolely through gravity — and that dark energy is more preciselyFundamental Energy (FE) — the basic expansive property of space,symmetric to gravity. Both are entropic invariants: FM occupies themaximum entropy state available to gravity-only matter; FE has zeroentropy as a uniform property of space. This entropic inertness is thestructural reason why FM and FE persist across cosmological transitionswhile ordinary matter does not. The cosmological constant problemdissolves once vacuum energy (matter sector, extractable via Hawkingradiation) and FE (spatial property, not extractable) are recognised ascategorically distinct — reducing the 10¹²² discrepancy to a boundarycondition, not a fine-tuning problem. Baryonic asymmetry emerges as astructural consequence of the inherited inhomogeneous FM distribution.The fine structure constant α is derived from the FM/FE energy inventory asa fixed-point relation, recovering the observed value to seven significantfigures. The framework makes falsifiable predictions testable with JWST,Euclid, DESI, and LISA. Part II Part I established that Fundamental Matter (FM) and Fundamental Energy(FE) persist across cosmological generations while ordinary matter (OM)cycles through black holes via Hawking radiation. Part II extends thisframework to the terminal state of the universe. We propose that the finaluniverse — in which all OM has been converted to FM and only a singleclass of black holes remains — satisfies two distinct trigger conditions thattogether initiate a new Big Bang: a geometric condition, in which externalFE volume exceeds internal volume, and a thermodynamic condition, inwhich black hole entropy converges on horizon entropy. These twoconditions constitute a chorus trigger: they need not arrive simultaneously,but both must be met. We further propose that our universe is the firstcosmological generation (n = 0), and derive that OM depletion reachescompletion within approximately 4 generational cycles under f = 0.844,derived from the observed OM fraction. The framework requires no inflatonfield, no external fine-tuning, and no appeal to structures beyond FM, FE,and classical thermodynamics. Fine-tuning is not imposed from outside —each generation, the universe converges upon its own constants throughthe self-referential structure of FM, FE, and α.
