The Dark Universe at Large Scales: A Unified Topological Mechanism for Voids, White Holes, and Ultra-Long Dark Jets

Within the standard ΛCDM cosmological framework, cosmic large-scale voids, white-hole solutions, and large-scale cosmic jets belong to three mutually independent and mutually incompatible physical pictures: cosmic voids are regarded as low-density residual regions produced by gravitational instability, exhibiting only passive and weak negative gravitational lensing, and possessing no independent dynamics; classical general-relativistic white holes are widely considered not to correspond to real universes because of their time-reversal instability; and large-scale cosmic jets are entirely attributed to the magnetohydrodynamic accretion mechanism of active galactic nuclei, with scales strictly confined to the central active regions of galaxies. The GDUM pre-geometric ontological framework provides a fundamentally different unified picture: the negative gravitational lensing of voids, the topological output of white holes, and ultra-long cosmic dark jets are not three independent phenomena, but rather the gravitational observational face and the matter-dynamical observational face, presented at the four-dimensional projection layer, of a single low-topological-winding-channel ontology. Based on the GDUM axiomatic system, the topological mass theorem, and the pre-geometric bidirectional conversion-kernel mechanism, this chapter establishes a unified large-scale topological dynamics of the dark universe in three parts, completing the closure of field-theoretic definitions, energy self-consistency, mechanism-homogeneous unification, five falsifiable cosmological predictions, and the deep correspondence with the pre-geometric holographic-dual structure. With the sole exception of Postulate S-01 explicitly marked in this chapter (extrapolated and anchored by Theorem 4.2), no exogenous new-physics assumption is introduced; all conclusions can be fully incorporated into the self-consistent ontological structure of GDUM.
