Predictions — DESI and no-dark-matter

Dated UQCF-GEM calls against community results. A 5 Mar 2025 directional prior on evolving dark energy landed 14 days before DESI DR2. Remaining w(z) / A_L / cluster-core forms are still tests. #nodarkmatter is program voice, not a DESI confirmation.

This is the dated prediction ledger for UQCF-GEM cosmology, DESI-first. On 5 Mar 2025 Spradlin posted a dynamic, not-Λ cosmos: a 13-parameter Planck C_ℓ form with D_f=2.4959, and the sentence “Redshift is a measure of coherence not time.” Fourteen days later DESI DR2 (arXiv:2503.14738, public 19 Mar 2025) preferred evolving dark energy over ΛCDM at 2.8–4.2σ (DESI+CMB+SNe). That timing is a directional prior on evolving versus constant dark energy. It is not uniqueness, not a fitted w(z), and not a no-dark-matter confirmation — DESI still uses CDM. The 30 Apr 2026 forms remain tests. #nodarkmatter is the program’s working voice.

What this page is not

It is not a claim that DESI confirmed UQCF-GEM, eliminated dark matter, or closed Package 17. The 21 Mar 2025 post names the 5 Mar packet after DR2 was public — a restatement, not a second prediction. The 5 May 2026 complete-cosmology sentence stays corrected. Hubble tension stays not-claimed. Challenge 14 and WALLABY stay Restricted gas-first empirical, not a dark-matter disproof.

Scoreboard

Grain: date, the posted call, the community result it faces, the atlas score, and the failure mode that would over-claim it. Editorial, not a cosmological likelihood.

Date Call Community Atlas score Not this
2025-03-05 Dynamic cosmos: Planck C_ℓ D_f=2.4959; redshift as coherence, not time DESI DR2 19 Mar: evolving DE 2.8–4.2σ (DESI+CMB+SNe) Directional prior (14 days earlier) Not uniqueness, not no-DM, not a fitted w(z)
2025-03-19 (community) DESI DR2 Results II, arXiv:2503.14738 Quintom-B, w0>-1, wa<0 Community result DESI still uses CDM

2026-04-28 / 05-02 WALLABY 12D 10/10; Challenge 14 SPARC 94.15% Frozen gas-first scaffold, unseen holdouts Restricted empirical Not a dark-matter disproof
2024-12-17 Euclid F>0.7, 20–30% P(k), 5% shape Euclid DR as a likelihood still pending Not scored Not an Euclid posterior
Program voice #nodarkmatter DESI DR2 still uses CDM Voice, not a DESI confirmation Evolving DE is not a DM result

Atlas score is editorial. A directional prior is not a unique forecast. Filing evolving dark energy as a no-dark-matter confirmation is a named failure mode.

The 5 Mar 2025 directional prior

Two same-day posts, fourteen days before DESI DR2 papers were public. Morning: redshift as coherence, not time. Later: a 13-parameter Planck C_ℓ form quoted at 0.54% RMS (ℓ=8–2048) against ΛCDM 2.3%, with D_f=2.4959. The 21 Mar restatement names that packet as a dynamic cosmos / fractal entropy (0.252748) call against ΛCDM’s constant. This atlas scores the timing: evolving versus constant, posted before the DR2 papers. It does not score uniqueness, a specific w(z), or no-dark-matter.

Redshift is a measure of coherence not time.

@aaronspradlin, 5 Mar 2025

DESI DR2 (3/19/25) reveals evolving dark energy (2.8–4.2σ)—UQCF-GEM predicted a dynamic cosmos, no dark matter, fractal entropy (0.252748), D_f (2.4959) on 3/5/25. DESI’s Lambda CDM predicted a constant—missed.

@aaronspradlin quoting Grok 3, 21 Mar 2025

Not claimed

The 5 Mar 2025 packet is scored as a directional prior on evolving versus constant dark energy, timed 14 days before DESI DR2. It is not treated as a fitted posterior, not as uniqueness, and not as a no-dark-matter confirmation. The 21 Mar post is a restatement after DR2 was public and is not scored as a prediction.

What DESI DR2 actually said

DESI Collaboration, “DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints” (arXiv:2503.14738). Papers submitted ~18 Mar 2025, public 19 Mar. Combined DESI+CMB+SNe prefer evolving dark energy over ΛCDM at 2.8–4.2σ, in the Quintom-B quadrant (w0 > −1, wa < 0). That is a community dark-energy result. The fit still uses cold dark matter. A preference for w(z) ≠ −1 is not a dark-matter disproof.

Not claimed

DESI DR2 is a community result this ledger faces. It is not an atlas confirmation of UQCF-GEM, and it is not a no-dark-matter result.

Open tests — 30 Apr 2026

A year later he posted an explicit retained-coherence form, plus two companion amplitudes. These are the remaining DESI-facing tests. They were not fitted to DR2. They are not scored as hits.

Redshift-dependent dark-energy equation of state: w(z) ≈ –1 + ε · (1 + z)^χ · exp(–z/z_c) with χ ≈ 0.2667 … This predicts a ~2–3σ deviation from w = –1 in the z = 0.5–1.0 bin — directly testable with DESI DR3 BAO data. Planck A_L ≈ 1.15–1.25; cluster-core convergence +10–15% at z>0.5.

@aaronspradlin, 30 Apr 2026

  • w(z) — ~2–3σ from w = −1 in the z = 0.5–1.0 bin, named as a DESI DR3 BAO test.
  • Planck A_L ≈ 1.15–1.25 — points at the known community A_L>1 tension; not a unique forecast of that tension.
  • Cluster-core convergence +10–15% at z>0.5 — CMB-S4 / Euclid-facing, not a DR2 posterior.

Open

The 30 Apr 2026 w(z) form, A_L ≈ 1.15–1.25, and cluster-core +10–15% at z>0.5 remain open tests against DESI DR3, CMB-S4, and Euclid. This atlas does not treat them as a confirmed DESI resolution.

Recorded null — frozen DESI operator, 4 Apr 2026

The quadratic RG sprint froze a solved core that was competitive with a damping-only Planck layer (aggressive reduced χ² ≈ 1.45; conservative ≈ 2.13). On a cleaner DESI observable-map reconstruction the frozen source+propagation operator stayed null / weak. A shared transient could help Planck and was rejected by DESI. That is a recorded null, not a hit. The 5 Apr coherence-history sentence is method voice from the same sprint, not a DESI posterior. Full freeze on the quadratic RG article.

In UQCF-GEM, redshift is not just expansion. It behaves more like a measure of coherence history.

@aaronspradlin, 5 Apr 2026

Open

DESI null on the frozen source+propagation operator is recorded. It is not scored as a prediction hit. The quadratic RG core remains an open derivation scaffold, not Package 17 closure.

#nodarkmatter is program voice

The working hypothesis of the program is that non-baryonic dark matter is not required — retained coherence, gas-first scaffolds, and fractal scaling are offered instead of a CDM particle. That voice is public and dated. It is not a DESI confirmation. DESI DR2’s evolving-DE preference is a dark-energy result inside a CDM fit. Filing 2.8–4.2σ evolving DE as a dark-matter disproof is the named failure mode on this page.

The empirical spine that actually carries a Restricted badge is the Great Grok Challenge, not DESI. Challenge 14: frozen SPARC 171, 94.15% positive, 0 catastrophic. WALLABY Round 12D: unseen DR2 subset, no SPARC overlap, 10/10, mean RMSE +14.56 km/s. Those are gas-first rotation-curve and HI-gas transfer tests. Grok logged Challenge 14 as a pass. This atlas keeps the box: not a dark-matter disproof, not a cosmological likelihood, not Package 17 closure.

Restricted

Challenge 14 (SPARC 171, 94.15% positive) and WALLABY 12D (10/10 unseen DR2) are Restricted gas-first empirical. They are not a dark-matter disproof and not a DESI result.

nodarkmatter is program voice. DESI DR2 does not confirm it. Evolving dark energy is not a dark-matter result.

Euclid 2024 forms — not scored

Day-before the ToI seed, a 17 Dec 2024 reply to Hugh Ross posted three Euclid-facing numbers: filament alignment F>0.7 (random ~0), 20–30% P(k) suppression at sub-Mpc, 5% galaxy-shape correlation excess. They remain on the ToI / TOE shelf. This ledger does not score them as Euclid hits or misses. They are not an Euclid likelihood.

Not claimed

17 Dec 2024 Euclid / ToI forms (F>0.7, 20–30% P(k), 5% shape) are archived as posted predictions. They are not scored here as an Euclid posterior.

What would count

  • Progress on the 5 Mar directional prior — a named, unique w(z) (or equivalent) that beats ΛCDM on DESI DR3 BAO in the z=0.5–1.0 bin at the posted ~2–3σ, with the Package 17 failure modes still in force.
  • Progress on A_L — a Planck / CMB-S4 posterior in 1.15–1.25 that is derived from the frozen χ, not pointed at as an existing tension.
  • Progress on cluster-core — a +10–15% convergence excess at z>0.5 in a named Euclid or CMB-S4 analysis, same χ.
  • Progress on no-dark-matter — a cosmological pipeline (Friedmann, BBN, CMB acoustics, growth) that survives Package 17’s listed seams without a CDM component. Challenge 14 is not that pipeline.
  • Failure — filing DESI DR2’s 2.8–4.2σ as a UQCF-GEM confirmation, as a no-dark-matter result, or as a Hubble-tension resolution. Failure — scoring the 21 Mar restatement as a prediction. Failure — promoting the 30 Apr sketch to Supported. Failure — treating the 4 Apr DESI operator null as a hit.

Open

A viable cosmological pipeline remains a Package 17 derivation target. This ledger keeps the dated calls visible so a later hit or miss has somewhere to land. Gravity stays a candidate.
