A Phase-Based Harmonic Interpretation of the Speed of Light: Base-12 Subharmonic Mapping of a Defined Physical Constant

The speed of light in vacuum is defined exactly as 299,792,458 meters per second in the International System of Units. This value functions as a fixed conversion constant linking spatial and temporal measurement. This paper introduces a phase-based harmonic interpretation of the speed of light using base-12 subharmonic mapping and logarithmic depth analysis.

Rather than redefining or altering the constant, the framework presented here provides a structured method for expressing the speed of light as a position within a harmonic lattice. By inverting the constant and mapping its magnitude into base-12 depth, the value is shown to occupy a stable subharmonic region between the 7th and 8th base-12 layers, with a fractional position corresponding to approximately 0.848 of the interval.

This fractional position is further decomposed into a discrete base-12 representation, yielding a structured sequence (5–A–8) which reduces to a boundary-adjacent state (11). The result is a consistent interpretation of the speed of light as a phase-locked constant occupying a hinge-to-boundary transition region within a harmonic measurement system.
