Quantum Mechanics: Experiments, Assumptions, and a Unifying Physical Framework

We present a structured summary of an oscillatory-spacetime framework in which the standard formalism of quantum mechanics arises from a single physical assumption. In this approach, elementary particles are modeled as localized spacetime singularities carrying an intrinsic oscillatory degree of freedom. The persistence and transport of this oscillation account for wavefunction structure, superposition, energy--momentum relations, spin, relativistic dynamics, antiparticles,and electromagnetic interactions without the introduction of independent postulates. This paper does not rederive the framework, but organizes its development by reviewing the key experimental observations that motivated quantum mechanics, summarizing the core assumptions of the standard theory, and showing how these structures emerge within the oscillatory-spacetime picture. The result is a compact guide for readers familiar with quantum mechanics that clarifies how its diverse elements can be unified within a single physical model.
