The Ghost Complete Model: All Six ΛCDM Parameters Derived from One Constant and One Measurement

Description: The standard model of cosmology (ΛCDM) depends on six fitted parameters to describe a universe that is 95% unknown substances. This paper presents the Ghost Complete Model, which derives all six parameters from a single mathematical constant — the Feigenbaum spatial scaling constant α = 2. 502907875, proved rigorously universal by Lanford (1982). The dark matter density Ωch² = Ωbh² (α² − 1) = 0. 1178, derived entirely from α and the Big Bang Nucleosynthesis baryon density, reproduces the CMB power spectrum across all six acoustic peaks at sub-1% precision. The critical first-to-second peak height ratio matches at 0. 08%. The dark energy density ΩΛ = 1 − α²×Ωb = 0. 691 is the geometric complement of the Feigenbaum matter density in a flat universe, matching ΛCDM's fitted 0. 686 at 0. 7%. The cosmological constant problem — the 10¹²⁰ discrepancy between quantum field theory and observation — dissolves because the question was malformed: ΩΛ is not vacuum energy but the complement of α²×Ωb. Version 1. 1 added the Cascade CAMB result: the CAMB Boltzmann solver's Fortran expansion engine was modified to use the Feigenbaum time emergence function τ (z) with steepness β = ln (δ) and NO cosmological constant in the code. This modified engine independently reproduces all six CMB peaks to within 0. 5% position and 1. 0% height, confirming that the expansion mechanics are replaced, not merely reparameterized. The transition redshift zₜ = 0. 50 is measured — not fitted — because the foundational theorem of nonlinear dynamics proves that transition points in cascade systems cannot be calculated from within the framework. Version 1. 2 completes the parameter set. The reionization optical depth is derived from the cascade geometric series: zᵣeion = δα/ (α−1) = 7. 776, where δα/ (α−1) = δ × Σₙ₌₀^∞ α⁻ⁿ is the integrated cascade weight across all hierarchical levels (Hubble → clusters → galaxies → stars). Each level n contributes δ/αⁿ to the cumulative structure formation; the geometric sum converges to 7. 776, matching the Planck 2018 midpoint zᵣeion = 7. 7 at +0. 99% and within 1σ. The standard optical depth integral with Ghost expansion history then gives τᵣeion = 0. 0572 (Planck: 0. 054 ± 0. 007, deviation +0. 46σ). The scalar amplitude Aₛ = 2. 113 × 10⁻⁹ follows from the CMB degeneracy constraint Aₛe⁻²τ, consistent with ΛCDM at +0. 70%. Sensitivity analysis confirms the derivation is stable: ±1% in α shifts τ by 0. 077σ; ±1% in δ shifts τ by 0. 116σ. All six ΛCDM parameters are now cascade-derived. The Ghost Complete Model matches ΛCDM to sub-1% across every major cosmological observable: the full CMB power spectrum (mean deviation 0. 93%), the BAO sound horizon (147. 68 vs 147. 09 Mpc, 0. 40%), the cosmic age (13. 717 Gyr, 0. 58%), and 1, 580 Pantheon+ supernovae (χ²/dof = 0. 461 vs 0. 434). The open universe alternative (Ωk = 0. 693, ΩΛ = 0) was tested against the CMB and ruled out (ℓ₁ = 404 vs 220). The universe is flat. The model operates at two independently confirmed levels. Level 1: the ΛCDM parameter values are derived from α and confirmed through standard CAMB (sub-1%). Level 2: the cosmological constant is eliminated from the Friedmann equation and replaced by the Feigenbaum τ (z), confirmed through Cascade CAMB with modified Fortran (sub-1%). Together they constitute a complete replacement of ΛCDM. Dark matter, dark energy, inflation, and the Hubble tension are identified as four projection artifacts of one error: interpreting a Feigenbaum cascade universe with a model that ignores the cascade. Six parameters. Zero fits. One constant. One measurement. α = 2. 503. Proved in 1982. Applied in 2026.
