Mysteries of Physics — Simple Explanations in SP3

This manuscript presents a set of well-known “mysteries” in quantum and foundationalphysics—including wave–particle duality, the double‑slit experiment,measurement/collapse, entanglement and nonlocal correlation, vacuum fluctuations,identical particles, quantization, tunneling, time’s arrow, the Born rule, and the emergenceof the classical world—in a plain-spoken, mechanism-first format. Each topic is framed intwo parts: (A) the intuitive gap that a lay reader experiences in the standard account, and(B) a proposed SP3 (Space‑Phase 3) mechanism that renders the same phenomenonvisually and physically interpretable as behavior of a structured medium. The intent is notto replace successful calculation methods used in contemporary physics, but to supply acoherent “how it works” story that connects propagation, boundary interaction, andinformation loss/retrieval within a single medium-based picture. The result is a compacteducational bridge document for general readers and scientists alike, designed to motivatetestable handles and clearer intuition for why the standard mathematics works.
