c as the Invariant Boundary Condition: Deriving the Structure of Human Sensory Experience

Title c as the Invariant Boundary Condition: Deriving the Structure of Human Sensory Experience Authors Christopher Description This paper treats the speed of light c≈2.99792458×108 c \approx 2.99792458 \times 10^8 c≈2.99792458×108 m/s not merely as the maximum propagation speed, but as the single fundamental invariant boundary that makes distinguishable, relational reality possible. We derive the qualitative and structural features of the five human senses (sight, sound, smell, touch, and taste) directly from this constraint. Finite propagation under the c c c boundary is shown to be both necessary and sufficient for the emergence of locality, temporal ordering, and coherent sensory experience. Each sense is shown to occupy a distinct regime on the propagation scale: Sight operates near the high-c c c boundary (near-instantaneous local mapping). Sound occupies the middle-c c c regime (rhythm, language, emotional coordination). Smell, touch, and taste sample the low-c c c and contact regimes (persistence, grounding, and chemical integration). The result is a unified “real view on reality”: human experience is the natural outcome of sampling different propagation speeds within the invariant ceiling set by c c c. We do not live outside the speed of light — we live within the rich, differentiated structure its finite value permits.
