Space Quantum Topological Emergence Theory (SQTE): Topological Grand Unification of the Four Fundamental Interactions

Based on the complete axiomatic system of the Space Quantum Topological Emergence Theory (SQTE), this paper constructs a three-dimensional core framework consisting of holographic active node density ρ , topological coupling coefficient ξ , and topological stability scale ϕ , which unifies and reduces the four fundamental interactions (gravity, electromagnetism, strong and weak interactions) to four basic evolutionary modes of the three-dimensional space quantum topological network. ρ defines the intrinsic type of interactions, ξ quantifies the hierarchical differences in coupling strength, and ϕ provides geometric stability constraints for topological configurations. A rigorous logical closed loop of "axioms → topological rules → interaction characteristics → experimental benchmarking" is realized throughout with elementary algebra. At high energy scales, the four fundamental interactions spontaneously converge to a unified mode with the evolution of the space quantum topological network, without the introduction of new particles, extra fields or higher-dimensional spaces. At low energy scales, the theoretical results accurately reproduce the laws of existing experimental observations, completely resolving the problems of scale fragmentation and auxiliary hypothesis accumulation in traditional physics, and providing a minimalist, self-consistent and strongly falsifiable underlying theoretical framework for the grand unification of physics.
