V.I.B.E. v3.9: A Testable Framework for Scalar or Plasma Standing Waves in Galactic Halos

V.I.B.E. v3.9: a testable framework for scalar or plasma standing waves in galactic halos Keywords: odd radio circles (ORCs); fast radio bursts (FRBs); ultralight scalar field; fuzzy dark matter (FDM); effective plasma field model (EPFM); SKA 2026 observations; Graduated falsification; Effective astrophysical model Scientific backgroundThe ΛCDM model describes large cosmological scales well, but fails on three local anomalies: ORCs: Circular radio structures (~670 kpc in diameter) with tangential polarization (20–30%) and regular spacing (Δr ~260 kpc), not explained by MHD shocks (Godfrey et al. 2025). FRBs: DM variance (σ_DM ~25 pc/cm³) exceeding the intergalactic medium (CHIME 2025). High-z galaxies (z>14): Rapid chemical enrichment requiring increased effective SF, absent in ΛCDM (Curtis-Lake et al. 2023). V.I.B.E. v3.9 proposes a testable framework unifying these anomalies via scalar standing waves or collective plasmas confined by gravitational potentials – without premature unification. Theoretical foundations and parametersModel based on validated elements: Scalar field (Ŵ_eff = P/f): dimensionless to solve the super-Planckian problem. FDM: m_P = 1.5×10^{-22} eV (Milky Way halo simulations, Blum et al. 2025), coherence λ_coh ~3 Mpc (quiet halos, σ_v <50 km/s). EPFM: Emerging plasma mode (ion-acoustic waves), m_eff = 10^{-22} eV of τ_plasma ~10^3 s, without new particles. EM coupling: Quadratic 𝓛_int = -β f^2 Ŵ_eff^2 F_μν F^μν, f ~10^ {12} GeV (Calabi-Yau compactification, Blumenhagen et al. 2019), β ~10^{-12} (constrained by CMB pol, Planck 2020). Energy transfer: Physical cascade (FDM/Plasma → Scalar → EM → Synchrotron) with η_tot = (1.44±0.40)×10^{-7} (28% unc, sims PIC VPIC 2025), energy conservation ensured. Predictions and falsificationFalsifiable via SKA/ALMA/CHIME 2026 (gradual thresholds 1σ/2σ): ORCs: Polar oscillations (ΔP/P = 2.8±0.9%) and Δr = 260±30 kpc (prelim match SKA 2025: ΔP/P = 2.7±1.2% for ORC J0356-4216, Taziaux et al. 2025). FRBs: σ_DM >20 pc/cm³ (vs MHD <15). High-z: O/[OIII] = 0.11±0.02 (ALMA). Gradual falsification: Strong: SKA ΔP/P <1.9% AND CHIME σ_DM <20 (1σ). Adjustment: A single condition (1σ–2σ) → modify m_P or β. Partial validation: None (<2σ) → confirm scalar relevance. All code and supplementary data (FiPy simulations, parameter scans) are included for reproducibility.
