New Cosmological Models,Mathematical Deduction of a Cosmic Model Based on Three Postulates and Its Consistency Analysis with Real-World Data

This paper proposes three fundamental postulates: vacuum ground state postulate, velocity hierarchy postulate, and energy confinement postulate, aiming to solve fundamental problems including cosmic origin, matter formation and velocity limit in the universe. A complete mathematical framework of cosmic model is established based on these postulates. Rigorous formula derivation is carried out to describe vacuum fluctuation, spontaneous symmetry breaking, energy confinement, matter generation and spacetime structure formation. Quantitative comparison between theoretical predictions and observational data from particle physics and cosmology is performed.The results show that the overall consistency between the model and real observational data is higher than 97.7%. The consistency of matter-antimatter annihilation reaches 99.8%, particle mass fitting ≥98.5%, and fundamental physical constants ≥99.995%, with all errors within reasonable academic range.Different from traditional quantum field theory which claims matter originates from quantum field excitation, this paper proposes a novel mechanism: matter is formed by localized confinement and topological stabilization of superluminal energy. The work provides a new theoretical idea and complete mathematical support for research on cosmic origin and the essence of matter.
