The Geometric Threshold of Matter: Differentiating the Primordial Substrate from the Discrete Phase Transition Grid

This paper investigates an alternative structural framework for spacetime, moving away from the mathematical continuum toward a discrete spatial matrix. It introduces the concept of the Primordial Substrate (Anadihilo), an ontological boundary-maker required by classical thermodynamics to prevent infinite structural dispersion and regulate entropy. Key highlights of the research include: The Phase Transition Threshold (i=10^-4): Deriving a fundamental discrete metric that acts as the geometric juncture where non-localized probability waves collapse into structured solid matter. Dimensional Normalization: Utilizing a 4² operator to translate planar informational interactions (2D) into volumetric structural realities (3D). Proton Radius Prediction: Establishing a direct topological proportionality between macroscopic electron orbitals and microscopic nuclear boundaries, yielding a predicted proton radius of approximately 0. 8422 fm. The Orbital-Nuclear Topological Folding Law: Proving that electron orbits and nuclear cores are geometrically identical manifestations operating on opposite ends of a structural grid filter. The framework provides a purely geometric perspective on atomic synthesis and offers a predictive volumetric scaling law for heavy elements without reliance on arbitrary curve fitting. 4.
