The Oscillation Principle

Entanglement Compression Theory (ECT) derives probability, deterministic quantum dynamics, and spacetime curvature from a single structural requirement: existence must persist as motion, and the simplest persistent motion is oscillation. From this requirement, probability, geometry, and general relativity arise as deterministic consequences rather than independent postulates. This paper introduces the Oscillation Principle, the assertion that static states are physically untenable and that oscillation is the only realizable form of existence. Energy, motion, and wave behavior are not separate constructs but a single entity, expressed concisely as waves = motion = energy. From this premise, entanglement, compression, and probabilistic structure follow as necessary outcomes. Planck units, historically treated as dimensional cutoffs, are reinterpreted as descriptors of the minimal oscillatory event: ℓₚ as spatial span, tₚ as temporal recurrence, and Eₚ as causal amplitude. These quantities define the indivisible unit of motion from which dimensionality arises. Dimensional extension appears as the projection of oscillatory amplitude, with curvature emerging when compression reaches its entropy boundary. Within ECT, the local speed of light arises from compression through c(x)² = T(x)/C(x), where T(x) denotes tension and C(x) compression. Probability emerges through deterministic energy partition, while curvature arises from compression gradients. The Oscillation Principle unifies these relations and provides a geometric interpretation of ℓₚ, tₚ, and Eₚ as properties of the primordial oscillatory event. Traditionally, energy, motion, and wave behavior have been treated as distinct categories. This framework resolves them as projections of a single oscillatory process, providing a unified foundation for quantum and relativistic phenomena. This paper serves as the conceptual foundation of Entanglement Compression Theory. The Oscillation Principle states directly that waves, motion, and energy are one, under the logical requirement that existence cannot be static.
