Aiming at core bottlenecks of modern physics, including the schism between quantum mechanics and general relativity, the lack of empirical support for dark matter and dark energy hypotheses, the absence of falsifiability in mainstream unified field theories, and the absence of first-principles explanations for mass and fundamental physical constants, this paper breaks through the traditional frameworks of geometric spacetime, point particles, and gauge boson theories to construct a new paradigm of cross-scale physical unification based on the Planck-scale vacuum superfluid. This study establishes the core ontological cognition of “the homology and symbiosis of spacetime, matter, and interactions”, proving that the vacuum is a superfluid substrate with zero viscosity and high elasticity at the Planck scale, and all physical phenomena in the universe originate from the elastic deformation and vortex topological self-organizing evolution of the vacuum medium. Taking relativistic fluid dynamics and pure elasticity as the only first-principles criteria, this research achieves a self-consistent unification of microscopic quantum, macroscopic relativity, and cosmic cosmology. This paper confirms that vacuum micro-element elastic repulsion is the only primary interaction in the universe, and the four fundamental forces are all secondary effects evolved from this primary force via topological scales; it strictly derives the origin of mass and mass-energy equivalence based on fluid dynamics, clarifies the geometric topological origin of the fine-structure constant, and systematically explains microscopic physical puzzles such as quark confinement and matter-antimatter asymmetry. Meanwhile, this work reconstructs the deterministic physical mechanisms of relativity and quantum phenomena, defines spacetime curvature as the gradient of vacuum density and pressure, and fundamentally eliminates the theoretical separation between quantum probabilistic phenomena and classical dynamics. At the cosmological level, this theory can self-consistently explain astronomical observation puzzles such as flat rotation curves of galaxies, mass offsets of galaxy clusters, and large-scale cosmic filament structures without introducing auxiliary hypotheses such as dark matter, dark energy, and cosmic singularities. This study constructs a physical unified system with the simplest parameters and mathematical self-consistency, providing a new deterministic theoretical paradigm for the research of fundamental physical unification. Keywords: Vacuum Superfluid; Vortex Topology; Cross-Scale Unification; First-Principles; Fundamental Interactions Version Note: Version 6.1 (708 revised original manuscript). This version revises and standardizes the full set of theoretical symbols, restores the original complete algebraic coefficients of vacuum stiffness and gravitational constant derivation in Appendix A/C that were simplified in Version 6.0, fixes dimensional inconsistency of Lagrangian cross-coupling terms, and removes redundant extended descriptive paragraphs unique to Version 6.0. Core optimizations of microscopic derivation: 1. The electromagnetic force derivation process is reorganized based on the intrinsic vortex topology of protons. The whole derivation contains no artificial fitting parameters, and the final deduced formula precisely matches the standard form of Coulomb's law. 2. The intrinsic geometric radius of electron vortex is newly solved through proton-electron circulation conservation, and the quantitative relation Re≈274rp is given with self-consistent numerical verification. The geometric source of π and 0.4 thickness ratio correction factors is supplemented, and the theoretical boundary constraints of superfluid zero viscosity are added throughout the text to improve logical rigor. This manuscript restores the original concise academic writing style of the theoretical framework, weakens over-extended qualitative discussion in cosmology, and retains all falsifiable physical predictions with standardized quantitative derivation logic.
