Gravitation as Phase Synchronisation

We derive gravitation on the finite relational substrate that forms the holographic encoding of the observable physical space-time. The derivation consumes three realisations: mass is the cardinality of a phase-locked cluster, distance is decoherence, and time is the observer’s scale-dilation. The substrate is a field and has no proper ideals, so a massive object is never an ideal of it: its frame drifts, and gravity is the relaxation of that forced drift.

Preprint: preprints202606.1018.v2. Validation notebook: Open in Colab (21/21 checks passing).

Each row carries one status tag. Every derived statement is a residue of the Carrier, never a conjecture: a small residue a bounded observer can access (a theorem), or an $\Omega$-hard residue fixed beyond the horizon. The remaining tags mark imported inputs, realisations, definitions and predictions. The blocks follow the paper: A the inputs, B the realisations (Section 3), C the derived rows (Sections 47), X what the construction explains and P the falsifiable predictions of the two subsections above, V the machine verification, Z the $\Omega$-hard residue. The source column names the body statement and, for every machine-verified row, the family identifiers of the validation package (grav.newton, grav.strongfield, …; one family per script, Section “Reproducibility”), the package’s records citing the rows in return. The programme’s development roadmap — the open derivations beyond this paper’s results — is maintained in the corpus master ledger, which carries A1 under its rows 00:A9 and 00:D1, B3 under its row 00:D3, B6 under its row 00:D5, C2 under its row 00:E3, C5 under its row 00:B7, C9 under its row 00:E1, C11 under its row 00:E4, C12 under its row 00:E5, C13 under its rows 00:E6, 00:E7 and 00:T6, C17 under its row 00:T5, C18 under its row 00:T2, C19 and P3 under its row 00:L1, C22 under its row 00:T1, C23 under its row 00:T4, C24 under its row 00:T3, P5 under its row 00:L7, and Z1 under its row 00:Z7.

#DescriptionStatusSource
A. Inputs: imported, not derived here
A1p21001The finite substrate: the torsor Carrier, coordinatized by a frame as $\F_\Omega$, its cardinality the Carrier identity $\Omega=4S+1$ with the measured $S\sim10^{122}$ (Planck units) locating the coherence horizon, with the phase cycle $C_{\Omega-1}$, the quarter-turn core $Q_4$, the drive (time is scale-dilation, each Subject’s own), the coherence horizon $\sqrt\Omega$, and the resolution floor $1/\sqrt\Omega$.I
master: 00:A9, 00:D1
A2p21002The three frame freedoms: the frame space is a torsor under $\mathrm{SL}_2(\F_\Omega)$, the spatial chart three-dimensional per frame, its continuum shadow the $3$-sphere.I
A3p21003The quadratic extension $K$, the Frobenius involution, the Lorentzian norm form, and the boost cycle (the Dirac layer).I
A4p21004Composite coherence: a bound cluster is one synchronised drive orbit (offset confinement, the $m$-body synchronisation lemma), coupling with coefficient $m$ against an incoherent $O(\sqrt m)$.I
A5p21005Lattice potential theory and the discrete harmonic Green’s function, with Coulomb asymptotics $1/4\pi r$.I

measured [GRAVITY Collaboration 2022; Event Horizon Telescope Collaboration 2022; McGaugh et al. 2016; Will 2014]
A9p21009The minimal-instance results consumed: the two-face count of the drift (angular $\kap/S$, temporal $\kap/(2S)$, ratio $2$ the double cover), the registration dictionary $p_{\mathrm{sl}}=3(S/\kap)\,r_g$ with the forcing $2\gamma-\beta=1$, and the mass–energy channel $C_{\p-1}\cap C_{2(\p+1)}=Q_4$.I
B. Realisations: mathematics as physics (the constitutive moves)
B1p21010Gravity is the relaxation of forced frame drift: a field has no proper ideals, so every embedded massive shell is non-ideal and its frame drifts; reducing the mutual drift (raising coherence) is identically motion toward smaller separation.R
§ 1, 3
B2p21011Mass is winding rate: the per-cell rate identification, one $Q_4$ datum in the channel $C_{\p-1}\cap C_{2(\p+1)}=Q_4$, tested against its falsifier at the instance [Akhtman & Voether 2026]; $E=mc^2=hf$ an identity; the composite coefficient $m$ is derived (C1), not constitutive.R

C11p21026The nonlinear completion forced: the exact cut-flux law (transfer antisymmetry) plus the winding grading forbid independent static self-sourcing, the clock-comparison cocycle makes the exponential reading unique (exactly the character $\gen^{-\Delta n}$, $e^{-u}$ its observer lift), and Deser’s bootstrap does not apply because what gravitates is winding rate.T

X. What the construction explains: the explanation register
X1p21041The cosmological-constant magnitude. $\Lambda\sim1/\Omega$ in Planck units is the curvature of the closed chart, the totality datum, not a vacuum energy requiring cancellation across $122$ orders. The fine-tuning problem is not solved but unasked.T R
§ 1
X2p21042No dark-matter particle. The radial acceleration relation is a registration crossover of the resolution floor, not evidence for undetected mass: galactic dynamics require no dark sector beyond the floor already fixed by $\Omega$.T R
Prop. 7.77.4; grav.deepregime
X3p21043No horizons, no singularities, no information loss. Collapse ends in a horizonless body, operationally black at $r_f$ (conditional on the fold-transition programme, C12), with an exact saturating interior profile — and information conservation is a theorem citation, not an absence claim: interior data live in offset sectors the drive confines exactly [Akhtman & Voether 2026]: the theory never forfeits predictivity.T R
Prop. 6.46.2
X4p21044Misner’s standing objection dissolves. The exponential metric is derived, not posited as a self-coupled field equation, so the field-equation pathology Misner identified in exponential-metric gravity does not arise here.T

V. Machine verification
V1p21056The validation package finite-ring-space/src/21-gravity: the paper’s twenty-one scripts as written, run through one registry as twenty-one families — the twelve of the original suite (grav.newton, grav.ppn, grav.strongfield, grav.fp_gauge, grav.branch, grav.fluxnoise, grav.rar, grav.deepregime, grav.radiative, grav.orderone, grav.rotating, grav.primordial), the eight of the revision rounds (grav.2pn, grav.1pn_eih, grav.binding, grav.counting, grav.defect, grav.inertia, grav.deepregime_orbit, grav.fold_echo) and the uniqueness proof (grav.fierz_pauli) — each family the script’s verdict over its labelled checks and printed PASS/FAIL lines, each naming the rows it witnesses; the notebook 21-gravity-main.ipynb executes them in the browser and the driver run_all.py writes results.json.T
Reproducibility; run_all
V2p21057The kinds, recorded per family: EXACT — decidable identities over finite fields, cyclotomic extensions, exact rationals, or symbolic identities with no tolerance in the verdict (fourteen families); CHART — a continuum reading (a limit, a series coefficient, a numerical extremum) or a comparison with measured data, tagged [approx]/[data] in the script, verdict by stated tolerance (grav.newton, grav.strongfield, grav.branch, grav.rar, grav.rotating); SIM — the seeded Kuramoto simulation of grav.fluxnoise, verdict by stated tolerance on time averages. The figures are regenerated by the package’s make_fig_*.py outside the run.T
Reproducibility
V3p21058What the run does not carry, stated: the comparable-mass $2$PN $\nu$-sector reduction (the failed first route is not shipped, per the corpus discipline; the $1$PN sector closed by grav.1pn_eih, the test-particle sector by grav.2pn); the imports and realisations of blocks A and B, which the suite consumes and does not check; the $\Omega$-hard residue Z1, absent by construction.T
Reproducibility; § 7.2
Z. Horizon: the residue beyond the bounded observer
Z1p21059The cross-scale running of $a_0$, the ratio $(\Omega-1)/d$: reduces to the factorisation of $\Omega-1$, the rate face of the Riemann scale operator.Ω
master: 00:Z7
Read by block, the surface is small. Imported (A1A9) are the substrate and its arithmetic, the Lorentzian–Dirac layer, the composite-coherence results of [Akhtman & Voether 2026], the lattice and synchronisation machinery, the continuum stiffness templates, the measured constants used for comparison only, and the minimal-instance results of [Akhtman & Voether 2026]. Realised (B1B6) are the six realisations, each stating what a physical term denotes in the substrate: gravity is drift relaxation, mass is winding rate, distance is decoherence, the clock tick and the decoherence count are one capacity, the objects we weigh are coherent composites, a frame change is a gauge symmetry — constitutive, not interpretive, each defended by the totality of its derived consequences and contested only through them. Everything else is derived (block C): from two definitions, one frame normalisation, one counting lemma, and the single composite realisation, with no field equation, action principle, or metric posited, the potential, the force, the equivalence principle, the redshift, the deflection, the perihelion, the frame dragging, the operational horizon, the area law, the radiative sector, the rotating solution, and the primordial spectrum come out as outputs. The explanation register X1X8 is what the construction dissolves or derives; the predictions P1P7 are the exposures this dependency structure offers, the acceleration floor and the registration crossover among them; V1V3 the machine verification behind every derived number. One residue sits beyond the bounded observer: Z1, the cross-scale running of $a_0$, $\Omega$-hard by the same factorisation of $\Omega-1$ that decides the number-theoretic instances of the horizon clause [Akhtman & Voether 2026], and the same object as the dark-sector residue of [Akhtman et al. 2026]. Tags: I 9, R 6, T 36 (C13C19, X1, X2, X3, X5, X6 composite with R), E 7, $\Omega$-hard 1. What the synchronisation reading adds to gravitation is the provenance of each part: the product $m_1m_2$ from coherent additivity, the $r^{-2}$ from harmonicity in the three frame freedoms, the universal sign from the shared arrow of the dilation, $G$ from the unit capacity of the relational channel, the equality of space and time bias from the unity of that channel, the slip core from its saturation, the operational horizon from its resolution floor; and, at the opposite end of the acceleration scale, the galactic transition from the same floor read as noise. One substrate, one channel, one floor; the constants are its bookkeeping.

Ledger history. 2026-06-23: the status section with three tables (what the construction explains X1X8, the predictions P1, P1’, P2P6, the predicate ledger A–C, Z); rounds 01–02 (June–July 2026) added C19C25 and the revision scripts. 2026-09-14 (T26): the three tables merged into one ledger in the corpus format — X and P are blocks of it, V added, every machine-verified row citing the family identifiers of the validation package (finite-ring-space/src/21-gravity), accession keys assigned; the row P1’ relabelled P7 (labels are a letter and a number).
