Empirical Investigation into the Discreteness of Matter and Physical Interactions, and the Minimal Unit Response Mechanism

This study focuses directly on physical material systems and interaction processes, systematically conducting an empirical investigation into discreteness through controllable structural cleavage and multi-type interaction transfer experiments. Through structural cleavage observations of homogeneous rigid matter and magnetic matter, we provide evidence that macroscopic material systems are constituted by the coupling of microscopic discrete unit clusters. Through transfer observations in mechanical, acoustic, optical, electrical, and thermal phase transitions, our findings indicate that the transfer processes of physical interactions possess discrete operational characteristics of packet-by-packet relay. Based on reproducible empirical results, this study establishes the cluster response mechanism of microscopic units, defining the inherent structural properties, cooperative operational rules, and cross-scale adaptive characteristics of the Equivalent Minimal Unit (EMU). We elucidate the statistical average emergence law of macroscopic physical representations originating from the cluster behavior of microscopic discrete units. We establish the ontological feature of minimal units: "external discrete independence and internal continuous indivisibility," suggesting that all macroscopic physical evolution originates from the fundamental response of minimal units. The results indicate that the discrete structure of matter, the discrete transfer of interactions, and the discrete response of microscopic units are inherent foundational operational characteristics of natural systems. All experiments are conducted under conventional conditions, are reproducible and verifiable, constructing a complete discrete physics system encompassing empirical phenomena, foundational mechanisms, unit essence, statistical emergence, and cross-scale laws.
