The Rotation Curve of NGC 3198 in the Torsion-Regulated Frame: A Computed Correction and Its Distance from the Data

This paper computes the change that the torsion-regulated Einstein-Cartan framework, organised by the Aldred Limit, predicts for flat rotation velocity of NGC 3198, whose published value is 150 km/s. The density of the system, estimated from its published properties by the estimator stated in the Methods, is 7.04e-23 kilograms per cubic metre. At that density the fractional correction to the effective gravitating density is 7.25e-81 on the neutron branch and 2.45e-74 on the electron branch, against a measurement precision of 5 per cent. The predicted change is therefore smaller than the precision by a factor of 6.90e+78 on the neutron branch. Inverting the comparison, the existing agreement excludes carrier masses only below 3.58e-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.
