Quantum Model of the Universe. Part II. Fundamental Hypotheses of Modernity

Preprint. This manuscript is a preprint and has not been peer-reviewed. It is currently under consideration for publication in a peer-reviewed journal. This volume develops the Quantum Model of the Universe (QMU) as a structurally organized theoretical framework in which cosmological dynamics, vacuum physics, quantum geometry, structure formation, and observational signatures are treated as logically connected layers of a single descriptive system. The central objective is not merely to collect hypotheses, but to arrange them into a hierarchy of physical description levels, each with explicit structural status, mathematical formulation, and observational interface. The material is organized according to a strict architectural principle: physical theory is presented in ascending layers, beginning with the fundamental carriers and substrates of physical effects, proceeding through geometric and dynamical laws, extending to domain structure and early-universe regimes, then to structure formation and nonlinear regulators, and finally to observational tests and complex-system consequences. Each hypothesis is formulated as a self-contained unit with explicit epistemic classification: empirically established, mathematically necessary, structurally implied, observationally indistinguishable within known limits, or open to refutation by observation. The global structure of the volume is divided into nine conceptual groups, each corresponding to a distinct level of physical description. The first group establishes the physical carriers and substrates of cosmological behavior, including the vacuum, multi-sector vacuum structure, dark-sector coupling, and fundamental background media that support effective cosmological dynamics. Here the vacuum is treated not as a parameter placeholder but as a dynamical structural component. The second group develops the quantum–geometric structure of spacetime itself, including quantum foam, network and discrete metric models, wave-mode gravity descriptions, and Planck-scale structural corrections. This level defines the geometric and quantum substrate on which macroscopic cosmology is built. The third group formulates the theory of cosmic expansion and accelerated dynamics, including structural acceleration mechanisms, effective cosmological terms, generalized Friedmann dynamics, and theorem-level constraints on late-time acceleration. This layer contains the core structural acceleration results and no-go regimes. The fourth group analyzes multi-domain and bubble cosmology, including multiverse scenarios, domain coupling, external-mass influence, and bubble-in-bubble structures, treating cosmology at the level of domain topology and inter-domain dynamics. The fifth group addresses early-universe regimes and ultra-early structural formation, including primary fluctuations, inflationary network mechanisms, pre-cycle inheritance, and early structural traces. The sixth group develops the physics of cosmic structure formation, including galaxies, protogalaxies, disks, gas dynamics, invariant formation laws, and scaling relations across early cosmic environments. The seventh group isolates black holes and compact objects as nonlinear structural regulators, treating their role in feedback, co-evolution, scaling, and structural control of galaxy formation and matter flows. The eighth group presents observational and correlation-based cosmological tests, including background correlations, survey missions, anomaly signatures, and cross-domain observables that form the empirical stress-test interface of the framework. The ninth group extends the structural analysis toward complex systems and global consequences, including planetary formation, astrobiological thresholds, civilization statistics, information and entropy structure, and the final structural acceleration theorems that close the logical chain of the volume. For practical readability and publication architecture, the nine groups are further organized into three books, each containing three groups and connected by dedicated transition chapters. This layered structure allows the reader to approach the framework progressively, moving from substrate and geometry to dynamics and structure, and finally to observation, information, and structural closure. The resulting organization is designed to function simultaneously as a reference compendium, a theorem-driven theoretical construction, and a falsifiable structural program in modern cosmology and quantum gravitational physics.
