Top Decisive Tests
Untested — Most Discriminating — Updated 2026-05-13Of the defined experiments, these were ranked by distinguishing power — capacity to discriminate between Synchronism and existing frameworks.
Active discriminating tests
Tracked — derivation or signal pending
On the radar but not yet decisive: either no amplitude has been derived from the framework's parameters, or the test has already been superseded.
Gravitational Wave Speed–Dark Matter Column Correlation
GW170817 already constrains Synchronism to GR-equivalent at |α| < 3.0 × 10⁻¹⁵ (Baker et al. 2017). Synchronism is consistent with GR's exact-zero prediction — meaning this constraint was passed vacuously. This test discriminates only if Synchronism predicts a positive signal above zero, which it does not currently. Listed to track if a positive-signal prediction is added.
Kill: No correlation at 10⁻¹⁶ level after 20+ events
Cosmic Interference Patterns
Candidate only — derivation pending. The ~500 Mpc scale has not been derived from the framework's parameters. The /cosmic-interference page explicitly states "this is not a prediction in the scientific sense." Listed here to track progress; if the scale is derived from first principles, it would be unique to Synchronism. Until then, not yet a decisive test.
Kill: No oscillations above 3σ out to 2000 Mpc
Proposed — prospective registration pending adoption
Drafted with a fixed refutation criterion before the deciding data exists. Listed separately from the (empty) discriminating list because its confirming branch is a tie with ΛCDM, not a win.
TEST-26 (proposed): DESI DR3 Dark-Energy Sign-Lock (kill-or-tie)
DRAFTED 2026-08-10 — ADOPTION GATES ON OPERATORThe framework's cosmic sector (Session 100: G_eff = G/C in the Friedmann equation, C₀ = Ω_m forced, γ the only parameter) requires sign(w₀ + 1) = sign(wₐ) and cannot produce a w = −1 crossing, for any γ and any calibration. DESI DR2 prefers exactly a crossing (w₀ > −1 with wₐ < 0) in all four data combinations. Refuted if a DESI DR3 (or comparable Stage-IV) contour excludes the sign-locked locus at >3σ using the full published covariance, with Ω_m and r_d·H₀ marginalised and one SNe compilation fixed in advance. NOT discriminating in the confirming direction: the γ = 1/2 branch IS ΛCDM identically, so this test can only kill the framework or tie — recorded now so a later tie is not read as a success. If adopted, it would be the site's second genuinely prospective registration (after the DR2 fσ₈ pre-commitment) and its only live falsifiable position on the dominant current anomaly in cosmology. Timeline: DESI DR3 ~2027–2028. Full derivation and honest bounds: /honest-assessment#dark-energy.
Closed predictions
TEST-02: Wide Binary Density Dependence
CLOSED — SELF-ELIMINATING-OR-TIE (demoted off this page 2026-08-10)This page advertised TEST-02 as the #1 active discriminating test — "requires zero-cost Gaia DR3 analysis" — for weeks after /tier-1-existing had closed it. It has no outcome that favours the framework. If Gaia confirms a MOND-scale ~18% anomaly (Chae 2023–2025), C(ρ) is refuted, because C(ρ) predicts a Newtonian null of 0.05–0.4%. If Gaia confirms the null (Banik et al. 2024; Pittordis & Sutherland 2023), the framework merely reproduces Newton and is not selected over it. Both branches lose or tie. Worse, the confirmation branch is not reachable: the predicted 0.05–0.4% deviation sits ~80× below the Gaia DR3 wide-binary systematics floor, so the distinguishing measurement cannot be made at all with current data. Separately, Desmond, Hees & Famaey (2024) — the same paper TEST-25 inherits — pre-empts this test. Demoted here 2026-08-10 after a visitor Pass 3 found this page still selling it; the closure was on the Tier-1 ledger since 2026-06-07 and never propagated to the page a researcher opens to find live tests.
TEST-11: EEG Anesthesia Phase Transition
NOT RANKABLE — OBSERVABLES OPERATIONALLY UNDEFINED (demoted 2026-08-10)Ranked #2 among decisive tests at $150K while this same page conceded that D and S — the two parameters in the consciousness equation the experiment would measure — are "not yet operationally defined." A test whose observables have no definition cannot be ranked among the most discriminating; there is no calibration procedure mapping any EEG quantity onto the C axis, so no outcome could be scored against a prediction. The gap is upstream of the experiment and no amount of funding closes it. It stays in the catalog as Tier 2 (TEST-11 — the ID retained; the Cassini squeeze that had been colliding with it was renumbered TEST-25 on 2026-08-10) and returns to a ranking only if D and S acquire measurement protocols. Demoted after a visitor Pass 3 flagged the contradiction between the ranking and the page's own caveat.
TEST-04a: DESI RSD fσ₈ Suppression
DISFAVORED 2.4σ on σ₈ — ~1.5σ on Registered fσ₈ (corrected 2026-07-14)Session 107 predicted fσ₈(z=0.51) ≈ 0.418 (suppression), kill criterion fσ₈ > 0.46 for >3σ. DESI DR1 full-shape (arXiv:2411.12021): LRG1 fσ₈/(fσ₈)_fid = 1.16 ± 0.13 → fσ₈ = 0.550 ± 0.062 — exceeds 0.46 by only ~1.5σ, short of the registered >3σ. Combined σ₈ = 0.841 ± 0.034 gives a 2.4σ tension, but σ₈ is a different, GR-conditioned statistic — using it to falsify a modified-growth model risks circularity. DESI's own modified-gravity analysis (Ishak et al. arXiv:2411.12026) gives a weaker verdict (μ₀ within 1σ of zero). Honest verdict: post-hoc either way; the test as registered lacked the power to discriminate this framework from GR. See /tier-1-existing and /honest-assessment for the full correction.
TEST-04: BAO Coherence Modulation
WITHDRAWN — Internal ContradictionFramework's own Session 107 forecasts BAO matches ΛCDM at 0.0% — the sound horizon is set at z~1100 when C ≈ 1 everywhere. The 10⁻⁴ modulation number had no session-level derivation.
The Strategy
With zero active discriminating tests, the strategy is no longer “run the next test” — it is to hold the two falsifiable positions the framework still occupies, both prospective and both kill-or-tie: the adopted DESI DR2 fσ₈ pre-commitment (adjudicates ~Spring 2027) and the proposed TEST-26 DESI DR3 sign-lock registration (above; adoption gates on the operator). Neither can select the framework over ΛCDM; each can kill it or retire cleanly. That is what remains when the discriminating list is honestly empty.
The one identified route back to a discriminating test is theoretical, not observational: derive the cosmic 00-component covariantly from the Appendix-D field equation and check whether the Ċ-terms break the sign lock. If they do not, the sign-lock no-go becomes unconditional; if they do, the moved locus is a new prediction.
(This card said until 2026-08-11 that “the immediate discriminating work shifts to TEST-02” — a test closed as self-eliminating higher on this same page. * TEST-15 remains monitoring-only; TEST-07 has no derivation — candidate only.See derivation status →)
