Redshift and the Dimensional Drift of Harmonic Space: Reinterpreting Cosmological Expansion through Sixtan Phase Geometry

Cosmological redshift has long been interpreted as a product of metric expansion and Doppler recession. In this paper, we propose an alter native view grounded in Sixta Theory: that redshift arises from phase displacement in a harmonically twisted manifold. Rather than stretch ing space, the observed redshift is due to differential phase embedding between emitter and observer. This paper presents the formal derivation of Sixtan redshift, compares it with traditional interpretations, and explores testable predictions in high-redshift anomalies, CMB uniformity, and lensed structures.
