Perfect Contrast Cannot be Obtained in the Electron Double-Slit Experiment

4 Application This paper offers a pivotal theoretical step in the development of the 0-Sphere electron model. It applies the previously established oscillatory two-point energy model (DOI: 10.5281/zenodo.16759284) to a longstanding puzzle in quantum mechanics: Tonomura’s observation that perfect 100% contrast is never achieved in electron double-slit experiments. This limitation had resisted theoretical explanation, leaving open whether it reflected a fundamental physical law or experimental imperfection. Building on the geometric framework of earlier works, the study proposes that the electron’s internal structure—two distinct kernels arranged along a 0-sphere geometry—explains this contrast limit. These kernels, which radiate and absorb Thermal Potential Energy (TPE), undergo temporal phase variations that alter the electron’s behavior during slit passage. When TPE condenses fully into a single kernel, the electron behaves as a point particle, and the interference pattern disappears entirely. This work forms a bridge between the initial geometric concepts of prior papers and the more developed internal-structure theories that followed. While the precise mathematical formulation of kernel dynamics was still under exploration, the paper demonstrates how the 0-Sphere model can resolve concrete experimental anomalies. The proposal that perfect contrast is fundamentally unattainable marks the first instance in which the framework directly explains puzzling laboratory observations—an important early step toward a complete internal-structure interpretation of quantum phenomena.
