The secant-based calculation yields: 137.sec(180°/137) ≈137.036028 This result aligns with the experimentally measured CODATA value (≈137.035999) with a precision of 99.9999%, showing a deviation of only 0.21 ppm (parts per million). This consistency suggests that the "Fine Structure" is not an arbitrary coupling constant, but a recurring Secant Phenomenon inherent to the geometry of the 6D Matrix.
Dirk Goussey (2026) studied this question.
