DDO 154 and the Dwarf-Galaxy Test of the Torsion-Regulated Frame: Why Low Density Means a Weak Correction
Year: 2026
Type: article
Abstract: This paper computes the change that the torsion-regulated Einstein-Cartan framework, organised by the Aldred Limit, predicts for maximum rotation velocity of DDO 154, whose published value is about 47 km/s. The density of the system, estimated from its published properties by the estimator stated in the Methods, is 1.11e-22 kilograms per cubic metre. At that density the fractional correction to the effective gravitating density is 1.14e-80 on the neutron branch and 3.85e-74 on the electron branch, against a measurement precision of 7 per cent. The predicted change is therefore smaller than the precision by a factor of 6.15e+78 on the neutron branch. Inverting the comparison, the existing agreement excludes carrier masses only below 3.79e-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.
