Scale Contrast Theory: The Veiled Sun, The Veiled Nucleus, The Veiled Pulsar Reconstructing Physics from One Invariant Across Three Scales

Scale Contrast Theory proposes that all stable cyclic systems — from planetary orbits to atomic transitions to pulsar spin periods — are organized by a single invariant: \kappa = (v/c)^2 \times (r/\lambda) = 1/2 . Through three thought experiments — the veiled Sun, the veiled nucleus, and the veiled pulsar — the paper demonstrates that masses, charges, and force laws are not foundational but are translations of relational depth. The framework derives the solar system's architecture from two planetary periods and one angular measurement; the hydrogen atom's Rydberg series from two spectral lines; and a pulsar's internal nuclear gradient from its spin period alone. Numerical predictions include a 0.3\% variance in \kappa across exoplanetary systems, a resolution to the proton radius puzzle via depth-dependent lepton sampling, and permanent glitch memory in pulsars proportional to glitch size with constant \approx 0.3 . The deficit \delta = 0.3 is shown to follow geometrically from binary contrast, cyclic closure, and self-similar division.
