MQ galaxy law connects to the established baryonic Tully–Fisher relation

The outer-galaxy limit links total baryonic mass to the fourth power of asymptotic rotation speed.

CHICAGO — The Measurement Quantization galaxy analysis connects its gravitational realization law to the established baryonic Tully–Fisher relation, which relates a galaxy’s ordinary-matter mass to its outer rotation speed. In the appropriate weak-acceleration limit, the MQ construction produces a fourth-power mass–velocity relation with a normalization set by its acceleration scale.

Figure 1 summarizes the source result and its evidentiary scope.

A limit is not every catalog velocity definition

Figure 1. Source-based summary of the construction and its stated limits. The panels organize the cited facts; they are not an additional physical derivation or a new observation.

The physical argument begins outside the dominant baryonic distribution, where a finite total baryonic mass supplies an inverse-square Newtonian acceleration. The weak-acceleration limit of the realization law changes the radial behavior of the realized field. The resulting circular speed approaches a constant, linking asymptotically flat rotation to the total baryonic source.

This is a connection among predictions of one law, not a claim that MQ discovered the empirical relation. The relation and related acceleration phenomenology predate the present manuscript. The specific MQ question concerns the proposed measurement structure and cosmological normalization underlying the law.

The limiting argument has conditions. A measured velocity at a particular radius need not already equal the asymptotic speed. Extended gas distributions, observational selection, pressure support, and mass-to-light assumptions can complicate a direct comparison between a theoretical limit and a catalog value.

The cited framework derives the acceleration normalization from its System Frame cosmology rather than fitting an independent value to every galaxy. That restriction makes the zero point and its dependence on cosmological inputs important parts of the test. A slope alone would not establish that the complete prediction agrees with observations.

A decisive empirical presentation should therefore report the mass estimates, velocity definition, intrinsic-scatter treatment, selection criteria, and normalization uncertainty. The theoretical connection is useful because a single prescription must remain consistent with radial acceleration, resolved rotation curves, and the mass–velocity relation together. These are related tests with shared data and assumptions, not automatically three independent confirmations.
