Silk Damping and the Spectral Distortion Window in a Torsion-Regulated Bounce

This paper computes the mu from Silk damping expected in a cosmology whose early collapse is regulated by spin torsion, and compares the result with FIRAS 95 per cent upper limit on mu. The predicted value is 1.550e-8 , against a comparison value of 9.000e-5 , a ratio of 1.722e-4 and a separation factor of 5.806e+3. The calculation starts from the Aldred Limit density for neutron matter, 9.72e+54 grams per cubic centimetre, follows the stated thermal and late-time assumptions for this channel, and keeps every intermediate step in the deposited code. The result is consistent with the published value at the level the comparison allows, and the paper states plainly which future sensitivity would turn that consistency into a discriminating test. No new observation is reported. The study is simulated and computed from stated assumptions, not measured, and its headline numbers are 1.550e-8, 9.000e-5 and 1.722e-4 for the predicted value, the comparison value and their ratio respectively.
