Space Compression Field Hypothesis: Postulate Construction, Mathematical Formalization, and Multi-Scale Cosmic Observation Systematic Verification

Feng Dejian Independent Researcher, Founder of the Unified Theory of Matter and Energy ORCID: 0009-0000-5793-9666 Web of Science ResearcherID: PQA-8034-2026 November 2026 Abstract This paper establishes and systematically verifies an original cosmic dynamic framework, namely the Space Compression Field Hypothesis (SCFH). Treating space as a compressible and stretchable dynamic physical medium, this theory introduces a local space compression coefficient field ε(r,t) and constructs a complete self-consistent system consisting of five fundamental postulates A1–A5 and one removable critical behavior conjecture C1. This research completes a hierarchical, near-to-far full-chain falsifiable verification system: (1) weak-field self-consistent symbolic verification to ensure the theory recovers the classical Newtonian limit; (2) hard magnitude constraint verification of laboratory-scale weak perturbations; (3) numerical integration of Mercury’s perihelion precession and multi-dimensional parameter grid scanning for dual constraint screening; (4) self-consistent pathological investigation of C1 critical expansion-contraction oscillation; (5) construction of a flat dynamic fitting framework for SPARC galactic rotation curves; (6) strict observational constraint verification of GRB high-energy vacuum dispersion; (7) deduction of a zero-dimensional homogeneous early universe model to complete pre-feasibility verification of CMB and BBN theories. All verifications strictly distinguish the fundamental postulate system, additional conjectures, and sub-physical interpretation models, forming a modular scientific structure where the falsification of sub-conjectures will not destroy the main framework. The results show that under the simplest constitutive relation, the SCFH framework possesses observational compatibility at the solar system and galactic scales and effectively avoids high-energy gamma-ray burst dispersion conflicts. However, unsolved gaps exist in the high-temperature and high-density evolution of the early universe, and the standard thermal evolution path of the early universe cannot be naturally reproduced under the current assumptions. This work realizes the academic standardized transformation from verbal hypothesis to computable, reproducible, and falsifiable physical models, with all numerical codes open-source and reproducible.
