CHICAGO — The cited MQ calculation specifies a positive 34.9284-parts-per-million separation between two proposed realizations of the gravitational constant, when expressed relative to the lower, electromagnetic value. The figure is a quantitative target for a measurement-regime hypothesis, not a declaration that conventional metrology recognizes two universal gravitational constants.
Figure 1 summarizes the source result and its evidentiary scope.
The result and its scope
Finite realization
6.6738448317 × 10⁻¹¹ in SI gravitational units
Upper-count realization
6.6740779383 × 10⁻¹¹ in the same units
Physical target
34.9284 ppm relative separation
The framework evaluates the same gravitational coupling in finite-count and upper-count regimes. The proposed values are 6.6738448317 and 6.6740779383, each multiplied by ten to the minus eleven in cubic meters per kilogram per second squared. Their difference is small enough that measurement configuration and correlated uncertainty are central to any comparison.
The physical motivation is the proposed Informativity differential, a count-dependent normalization distinct from relativistic contraction. It remains finite in the electromagnetic realization and approaches zero in the upper-count limit.
The broad distinction between electromagnetic and macroscopic measurement approaches predates the 2026 NIST/BIPM result. Assigning the particular electrostatic-servo and free-deflection modes of that apparatus to MQ’s regimes was a later interpretive step. The cited evidence classification therefore treats the comparison as retrospective compatibility rather than a preregistered causal test.
The numerical target is useful precisely because it can be challenged. A future apparatus should specify its mode assignment, calibration, expected correlations, and systematic-error treatment before the result is known. A measured difference would then need to be compared with both the MQ target and credible instrumental alternatives.
The central reporting distinction is between a theory’s two evaluations and two independently established physical constants. MQ proposes the former. Whether an apparatus realizes that distinction is an empirical question still requiring a more decisive test.
