A Field-Theoretic Approach to Torsion-Induced Phase Effects in Cosmological Redshift

We propose a field-theoretic mechanism in which spacetime torsion induces cumulative phase modifications in electromagnetic wave propagation, leading to observable deviations in redshift without altering the global ΛCDM expansion framework. Unlike conventional interpretations, the model predicts a structured dispersion in high-redshift observations, arising from non-uniform torsional domains rather than stochastic noise. This framework yields testable signatures, including non-Gaussian redshift distributions and directional dependencies in deep-field observations. Preliminary comparison with JWST data suggests consistency with these effects, motivating future observational tests of spacetime torsion as a measurable cosmological phenomenon.
