Bounce cosmology · live research program

Was there a bounce before the Big Bang?

This is an open, falsifiable research program asking one question: can a nonsingular Big Bounce cosmology — a universe that contracted and rebounded rather than began at a singularity — beat the standard ΛCDM + inflation picture? We attack it from both ends: deriving where a bounce could leave a fingerprint, then mining tens of millions of archival survey sources to look for it.

Six papers, honest nulls, and quantified falsification windows — with the decisive test (SPHEREx, ~2028) already on the calendar. Everything here is public: the PDFs, the datasets, the models, and the code.

How every claim here gets vetted

Every result on this site has been through 151 adversarial review rounds — model families from five different labs told to refute each paper, plus independent external referees, with a separate integrity audit on the review process itself — and 80 closure waves fixing what those rounds found. The loop has caught real errors (an overlap-inflated significance, a mislabeled catalog tier) before any reader could. The complete record is public — most recent: 2026-07-15.

Two clocks. This ETA is the review-loop clock — time until each paper stops surfacing genuinely-new findings (2consecutive clean review waves). It assumes 0 new findings from here; a single genuinely-new finding on any paper resets that paper's streak and pushes the ETA out. Journal acceptance is a separate, external clock — it depends on human referees and takes months. This widget does not predict that. See the verdict trajectory →

How the six papers fit together

One program, two halves

The theory arm (P1A, P1B, P2) asks where a nonsingular Einstein–Cartan–Holst bounce could leave a falsifiable fingerprint, proves the bounce mechanism itself is invisible to telescopes, closes the enumerated dark-energy routes, and isolates the one surviving handle — a parameter-free matter-bounce non-Gaussianity SPHEREx can test. The data arm (P3, P4, P5) mines 45M+ archival sources for the parity- and anomaly-level signatures any bounce would have to imprint, and reports honest nulls with quantified falsification windows. Negative theory results narrowed the search space; the surveys then went looking exactly where the theory said to look.

P1AECH theory + no-go: a perturbation-transparency theorem and a 14-constraint channel-level closure of the four minimal bounce→dark-energy routes.
P1BMCMC + pipeline companion: frozen ΛCDM+ΔN_eff chains (honest null), NaMaster recovery, and an ALP-birefringence consistency check.
P2f_NL = −35/16 forecast: the surviving falsifiable handle — matter-bounce non-Gaussianity, ~300× inflation and opposite sign, testable by SPHEREx at 3–5σ.
P3Multi-survey anomaly catalog: 378,280 unique anomalies across 7 surveys + a NANOGrav free-spectrum slope consistent with matter-bounce γ = 3.0.
P4Galaxy chirality null: 8.47M classified galaxies, a null +0.41σ real-space dipole, refuting the claimed ~3% parity signal at scale.
P5DESI chirality × environment null: spiral handedness is independent of cosmic-web environment, constraining environment-coupled parity models.

The evidence

The six papers

P1AMinimal ECH algebraic note62% readyv1A.0.123

A compact CQG Note deriving the minimal Einstein–Cartan–Holst axial contact interaction and the zero-spin canonical-scalar branch. It fixes conventions, separates coefficient-level statements from state-dependent observables, and provides a commit-pinned hard-cutoff NJL diagnostic. A subscription-backed exact-PDF reviewer returned ACCEPT with no tagged findings; human, release, and external-science gates remain.

P1BStandalone technical verification companion56% readyv1B.0.108

Standalone P1B is restored alongside the retained P1U history. Its exact NaMaster bandpower-window validation recovers β=0.269° from a +0.270° injection (bias −0.001°) on an explicitly synthetic native-coordinate latitude window. v1B.0.108 also renders the unconditional N=100,000 prior-predictive method and complete 195-artifact provenance inventory. This is pipeline calibration, not a sky measurement; readiness remains capped at 56 with no v1B.0.108 or human ACCEPT claimed.

P2f_NL = -35/16 SPHEREx forecast + Cai-Li certification74% readyv1.7.122

Derives f_NL = −35/16 for the stated matter-contraction background and cubic action, then maps that result conditionally to published and in-house large-scale-structure sensitivity estimates. The observational forecasts are illustrative, not a completed detection claim.

P3Multi-survey anomaly catalog56% readyv3.2.0-r8

Recovers 181 public DESI DR1 TARGETIDs from a frozen historical anomaly list, split transparently into 170 high-coordinate-consistency core associations and 11 lower-confidence positional associations; this is an archive-recovery product, not a purity, novelty, or detection claim.

P48.47M-galaxy chirality null at sub-percent sensitivity80% readyv1.0.244

Classifies 8.47M galaxies for spiral handedness with a rotation-equivariant ViT ensemble and finds a null real-space chirality dipole (+0.41σ, rank-p=0.31; A_dip < 6.8×10⁻³ at 95% UL) — the earlier −0.122σ subsample-mask null was withdrawn in v1.0.166 after a provenance audit.

P5DESI environmental chirality independence74% readyv0.1.133

On the released DESIVAST GALZONE parent, the focal exploratory analysis detects no void/non-void difference in classifier-labelled CW fraction; this bounded non-detection does not establish physical environment independence.

Program status67% average readiness

All six papers are drafted, internally peer-reviewed across multiple independent models, and have passed repeated adversarial review rounds with their numbers reproduced from committed code. The remaining step is the author's final sign-off and a coordinated arXiv submission — the science is in place; what's left is publication logistics.
