Dark Matter, Cosmic Void and Cosmic Bubble as Three Phases of One Essence: The Dahli Model

This paper documents a single thesis of the Dahli Model: dark matter, the cosmic void and the pure cosmic bubble are not three different entities but three phases of one essence, the pure cosmic mass. The pure cosmic bubble is the unquantized phase; dark matter is the same mass quantized into pure white-hole singularities and maintained by a quantized gravitational relation GDM ; the cosmic void is the same mass after the depletion of that relation, unfolded and organized by a distinct relation Gmem . The essence is conserved across the phases, MDM + MV = Mtot, so the growth of the cosmic void is the unfolding of mass already present in the quantized phase and does not require the creation of mass. Dark energy, defined in the model as the totality of pure cosmic energy singularities not activated into universes, is external to this mass; while the void persists it is in interaction with that external energy, and the pure bubble is reached when that influence ceases. The paper sets out what each phase is, how the phases are related, what is conserved, why the thesis answers the question of where the mass of a growing cosmic void comes from, and what the thesis does not claim. It then states the observational consequence that follows, a decrease of the comoving clustering dark-matter content, and is explicit that this consequence is necessary but not sufficient, that current data neither confirm nor exclude it, and that the mathematical formulation is reserved for subsequent work. The background definitions (pure matter, white-hole and black-hole singularities, the pure force string, the graviton, dark energy) were established in an earlier paper and are only summarized here.
