The Unity of Matter and Energy —On the Formation of Micro‑Particles and Energy Differentiation from the Perspective of Singularity Evolution

This paper, together with the previous work Physical Existence of the High‑Energy Singularity, initiates a comprehensive study on the high‑energy mass‑condensed singularity. From different perspectives, they jointly demonstrate the unity of matter and energy as well as the objective physical reality of the high‑energy mass‑condensed singularity. While Physical Existence of the High‑Energy Singularity comprehensively argues for the physical rules governing the high‑energy mass‑condensed singularity from a static viewpoint and in terms of the energy‑mass structure of micro‑particles, the present paper corroborates the conclusions and theories of the previous work by investigating evolutionary dynamics of the high‑energy singularity and the formation chain of micro‑particles, and further deduces an extended theoretical system. Mutually embedded, complementary and mutually supportive, the two papers together build a brand‑new physical framework for high‑energy‑singularity physics. This is the second paper in the series The Cosmic Large‑Cycle Repeating and Cyclic Evolution Model — An Expansion‑Contraction Cyclic Evolution Theory of the Universe Based on Bidirectional Mass‑Energy Conversion, serving as a sister paper to Physical Existence of the High‑Energy Singularity. Its core propositions are: first, matter is not an entity independent of energy, but a structural form of existence of energy‑density gradients; second, the evolutionary process of the high‑energy mass‑condensed singularity follows the physical law of symmetry‑breaking phase transition of energy‑(mass) density. Based on a set of innovative notions including the degree‑of‑freedom of energy, space‑evolution kinetic‑expansion‑contraction energy, symmetry‑breaking phase transition of energy‑(mass) density, and density‑gradient evolution mechanism, this paper systematically elaborates the complete evolutionary path of the singularity: from the merging of germinal bodies, quiescent heat accumulation, to unfolding phase transition, escape of space‑evolution kinetic‑expansion‑contraction energy from the high‑energy body, and the consequent so‑called “Big‑Bang” leading to the deconstruction of the high‑energy body. It reveals the underlying logic for the origin of micro‑particles and energy differentiation, and achieves the ultimate unity of matter and energy. Moreover, the origin of micro‑particles and the unfolding of large‑scale cosmic structures are incorporated into a self‑consistent first‑principle narrative. The study indicates that the symmetry‑breaking phase transition of energy‑(mass) density constitutes the core physical law governing singularity evolution. At each volume and corresponding temperature point, this law “filters” regions of energy‑mass density: parts “unfiltered” retain their original density state, while “filtered‑out” parts undergo successive density reduction to form density‑gradient structures of micro‑particles, which are activated as micro‑particles in the Big‑Bang event. This paper further puts forward the Wang‑Shan‑Zhang critical density and the concept of energy‑mass‑density gap, and illustrates their fundamental physical significance: they provide the structural guarantee for stable cosmic evolution, ordered reincarnation and replicative cyclic recurrence.
