The Baryonic Tully-Fisher Relation as a Quantity of the Torsion-Regulated Frame: Slope, Normalisation, and a Computed Tilt

This paper computes the change that the torsion-regulated Einstein-Cartan framework, organised by the Aldred Limit, predicts for baryonic mass at a flat velocity of 200 km/s of the SPARC baryonic Tully-Fisher sample, whose published value is about 7.5 x 10^10 solar masses. The density of the system, estimated from its published properties by the estimator stated in the Methods, is 2.23e-22 kilograms per cubic metre. At that density the fractional correction to the effective gravitating density is 2.29e-80 on the neutron branch and 7.74e-74 on the electron branch, against a measurement precision of 4 per cent. The predicted change is therefore smaller than the precision by a factor of 1.75e+78 on the neutron branch. Inverting the comparison, the existing agreement excludes carrier masses only below 7.11e-31 electronvolts, and the system would need a density of 9.72e+55 kilograms per cubic metre for the correction to reach one per cent. The result is a null result, stated plainly: this observable neither supports nor meaningfully constrains the framework, and the framework contributes nothing to the interpretation of this system beyond standard gravity. Computed from stated assumptions and published data; not a new measurement.
