A Unified Continuous-Wave Interpretation of Quantum Phenomena: --- Phase Evolution, Non-Zero Energy, and a Reconsideration of Probability ---

This paper presents a unified conceptual reinterpretation of quantum phenomena based on continuous wave evolution rather than intrinsic probabilistic ontology. By integrating prior conceptual analyses of wave–particle duality, phase evolution, non-zero energy states, and the interpretative status of probability and superposition, the work argues that the wave equation itself may provide a sufficient and complete dynamical description of physical behavior. Interference, diffraction, and localization are explained through deterministic phase evolution and boundary-condition interactions, while probability is repositioned as an a posteriori statistical description of measurement records rather than a foundational physical principle. The framework aims to simplify the conceptual structure of quantum theory and clarify the interpretive roles of phase, superposition, and observation without heavy reliance on mathematical formalism.
