3U MODEL – Universally Uneven Universe - A Spiral Geometric Framework for Cosmological Observations Without Dark Energy v1.0

3U MODEL – Universally Uneven Universe A Spiral Geometric Framework for Cosmological Observations Without Dark Energy Authors: László Tatai (Barefoot Realism Labs / 4M2M Research Collective) Date: 2026-06-05 ORCID: https://orcid.org/0009-0007-5153-6306 Abstract The 3U Model proposes that the universe is fundamentally spiral in structure. A minimal geometric framework with only three parameters (b, γ, δ) simultaneously explains: - The 4 billion light-year galaxy wall (the largest known structure)- The redshift z = 0.286 at this wall- The Hubble tension (local vs. global H0 measurements)- The DESI acceleration (apparent, without dark energy)- The CMB temperature (geometric, not a relic)- JWST early galaxy observations (no "too mature" paradox) The model requires no dark energy and no dark matter – only spiral geometry (b), Einstein–Cartan torsion (γ), and metric feedback (δ). Calibrated values (from 42,875-configuration grid search):- b = 0.6235 (≈ 1/φ, inverse golden ratio)- γ = 0.0476 (impedance coupling)- δ = 0.3415 (metric stretching at density peaks) Achieved accuracy:- Distance error: -0.038%- Redshift error: -0.46% Repository contents - Full mathematical derivation (spiral metric, Christoffel symbols, Ricci/Einstein tensors)- Numerical simulation code (Python, NumPy, Matplotlib)- Stationary solution and time dilation visualization- Cross-validation and robustness tests- English and Hungarian documentation License CC-BY 4.0 with Hungarian supplement Origin of the Name The abbreviation 3U stands for Universally Uneven Universe: - Universally – the model is scale-invariant; the same rules apply from Planck length to the cosmic web- Uneven – space is not homogeneous or isotropic, but spirally distorted (uniformly uneven)- Universe – the model describes the entire observable cosmos The three parameters (b, γ, δ) organize cosmological observations into a single geometric framework – without dark energy or dark matter. Statement "This work is published in the spirit of open science. The model may be wrong – but if so, at least others will not repeat the same mistake." – L. Tatai Cite as: Tatai, L.
