Satellite Galaxy Velocities Around Milky Way Analogues in the Torsion-Regulated Frame: A Computed Dispersion Shift

This paper computes the change that the torsion-regulated Einstein-Cartan framework, organised by the Aldred Limit, predicts for satellite velocity dispersion around a host of Milky Way-mass hosts in the SAGA survey, whose published value is about 120 km/s. The density of the system, estimated from its published properties by the estimator stated in the Methods, is 8.01e-25 kilograms per cubic metre. At that density the fractional correction to the effective gravitating density is 8.25e-83 on the neutron branch and 2.79e-76 on the electron branch, against a measurement precision of 15 per cent. The predicted change is therefore smaller than the precision by a factor of 1.82e+81 on the neutron branch. Inverting the comparison, the existing agreement excludes carrier masses only below 2.20e-32 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.
