The Descriptive Physical Cosmological Model for the Formation of Spacetime and Matter and the Prelude to the Cosmic Differentiation

A Physical Cosmological Framework for the Formation of Spacetime and MatterThis section paper provides a direct physical translation of all stages of the cosmological narrative into terminology from astrophysics, cosmology, and plasma-fluid dynamics, while completely excluding literary or metaphorical terminology. 1. Spacetime Genesis and Initial Expansion Stage (The Opening of Spacetime Domains and Dimensions) The fabric of spacetime (Spacetime Genesis) emerges simultaneously with the emergence of vacuum energy from a singularity point or from the horizon of absolute dimensions. This emergence is accompanied by cosmic geometric symmetry and by the symmetric establishment of spatial and temporal coordinate vectors and geodesic trajectories throughout the entire expanding spatial domain. 2. Primordial Cosmic Fluid and Opposing Radiation-Pressure StageThe initial energy condenses into a high-density, high-viscosity primordial plasma (Quantum Fluid / Relativistic Plasma) filling the cosmic volume.This fluid medium is subjected to high-intensity radiation-pressure forces and vacuum-energy pressure (Dark Energy / Quantum Pressure) acting against gravitational collapse. These effects serve as a dynamical stabilizing mechanism that prevents severe gravitational collapse and maintains the stability and geometry of the fluid medium within an approximately flat region.3. Cosmic Turbulence and Hydrodynamic Perturbation Stage Physical Interpretation Higher-order field effects or external perturbations (Higher-Order Quantum/Field Fluctuations) enter the system and generate hydrodynamic turbulence and mechanical instabilities in the fluid medium, including candidate instabilities such as the Rayleigh–Taylor instability.This intense and persistent perturbation produces continuous stirring and interpenetration of the primordial cosmic plasma, corresponding to a possible mechanism of turbulent phase mixing.4. Phase Differentiation and Celestial-Structure Formation Stage (Vapor, Dust, and Stratified Layers)As a consequence of thermal mixing and cosmological phase evolution, the less-dense and lighter components are assumed to migrate toward regions of lower effective density, contributing to the formation of large-scale gaseous structures and radiation fields (Cosmic Web / Stratified Plasma Layers).These structures and spatial layers are assumed to reach states of hydrostatic equilibrium and dynamical/orbital equilibrium without requiring mechanical material supports, with their evolution governed by gravitational interactions and the underlying dynamics of spacetime.5. Surface Deposition and the Independent Formation of Terrestrial Matter The high-density components and heavy elements produced through phase separation accumulate at the surface or boundary of the fluid medium, forming the first primordial condensed solid structures (Primordial Accretion / Surface-Crust Differentiation). Cosmochemical Interpretation The model proposes primordial elemental segregation. The Earth contains a broad spectrum of light and heavy elements represented in the periodic table, whereas stars in their early stages of stellar evolution initially derive their nuclear energy primarily from the fusion of light nuclei, particularly hydrogen and helium, and cannot produce the full range of heavier elements through ordinary hydrogen burning alone.Accordingly, within the proposed model, terrestrial solid matter is interpreted as the result of an early and potentially independent pathway of condensation and deposition relative to the central protosolar disk, rather than as material simply separated from a chemically immature stellar mass.
