Facts and deciding observations

The numbers, their evidence grade, and the data that can decide.

The fixed expression

G = (4/3)(ℏc/me2) α21e−5α/2
The registered prediction is 6.674312278 × 10−11 m³ kg⁻¹ s⁻². Current direct evaluation gives 6.674312283 × 10−11; the last-digit difference is input precision, not retuning. Residual tests retain the registered number.

α(0) is the fine-structure constant at zero momentum transfer (the Thomson limit), me the electron pole mass and G the static laboratory constant. h and c are exact SI definitions; α and me are measured inputs, not outputs.

Measurement status

CODATA 2022: (6.67430 ± 0.00015) × 10−11. NIST 2026: (6.67387 ± 0.00038) × 10−11, in the same SI units. The prediction is +1.84 ppm from CODATA and 1.16σ above NIST. CODATA is a recommended value, not independent apparatus; these rows must not be combined into extra significance.

Input precision is not theory certainty

The input-only relative uncertainty is 3.9 × 10−9, about six thousand times below measured G uncertainty. No physical theory-error band has been derived. A precise calculation can be precisely wrong.

The search that found the number

The audit contains 2 188 529 positive expression values and 100 000 random targets. At the frozen 1.85 ppm window it gives 148 hits (0.148%). At G’s 22.47 ppm measurement uncertainty it gives 1 614 hits (1.614%); accounting for six to twelve comparable searches leaves 0.93–1.32σ. Wider windows were post-review sensitivity checks, not a new frozen verdict.

Established, and not established

The numerical evaluation and audit are reproducible calculations. The discrete factors were chosen with G known. Agreement alone is weak evidence. Neither the match nor a mathematical group identity establishes a law of gravity.

A target already under pressure

Under H3 and the heavier neutrino assignment the corrected sum is 87.76–89.02 meV. DESI DR2 with CMB gives a 64.2 meV 95% bound in ΛCDM: the target is outside that limit, about 2.8σ away, and meets its registered below-80-meV imminent-falsification trigger. No second independent Stage-IV bound was found by October 5, 2026. In w₀wₐCDM the 126–177 meV bounds allow it; that model-dependent survival is not confirmation.

Conditional tests and their dates

Windows are approximate. Internal registration is not automatically public priority; data published before registration are retrospective comparisons.

Refuted claims stay visible

  • The specified minimal real, weakly coupled, strictly unitary G₂ × F₄ cubic construction fails—not every theory bearing those symmetry names.
  • The dominant canonical next-rung fuzzy-dark-matter scalar is excluded—not arbitrary noncanonical sectors.
  • Raw epsilon sums are uncontrolled; they yield no spectrum verdict.
  • A truncation fold was wrongly treated as absence of the carrier at five; that inference is withdrawn.
  • Block exchange does not protect maximal atmospheric mixing or CP in the physical flavour basis.

A correction, not a silent replacement

The original heavier mass-sum band was 87.106–88.361 meV. An atmospheric mass-splitting input used the wrong mass-index convention. The corrected 87.76–89.02 meV band retains the original assignment and records the correction date, October 5, 2026.

Data and reproducibility

The twelve deposited files are listed below and on the papers page. The registration ledger preserves internal dates and provenance; they are not independently verifiable public priority records. Earlier solver software and raw run artifacts are not in this deposit.
