The Multiverse Mirror Cosmology v1.1.1 proposes a dual-meta framework: Asymmetric metaverses – negative (E Meta- 0, matter-dominant) – exchange “sight” (holographic info via ϕ a -tunnels) and energy (∆E Meta ∼ 10 −10 ) to prevent collapse, spawning infinite uniwith E(u 1 b ,x)=−E(u 2 b , x), zero total E total,b = 0, and global −E Meta- +E Meta+ = b E u b = 0. Meta-leabk verses from interference (E u b =β(E Meta+ + iE Meta- )). Each bubble b has two-sheeted spacetime U 1 b ⊕U 2 α ± ∝ ϕ ±0 ∼ 10 −10 feeds mirrors, triggering void-in-void bounces θ(ρ PBH,b −ρ crit )δ bang,b ρ c (ρ crit ∼ 10 −25 kg/m 3 ) for emergent exoticism (e.g., H 0,b ≈ 70 ± 3 km/s/Mpc). PBH pairs as ER=EPR bridges yield Λ eff,b = 8πG⟨J E,b ⟩ (varied, entropic origin 1/S ≈ 10 −120 ). Hawking reversal T u 2 bH =−T u 1 bH sign(U b ). Sterile neutrino fuzzy dark matter (m s ∼ 3 keV, sin 2 (2θ b ) ∼ 10 −10 , Ω ν s ,b h 2 ≈ 0.12) with drags ∆m 2b ∼ 0.05 eV 2 (z-dependent scatter on active sector). Emergent G(ϕ a ,T b )=G 0 /(1+ κϕ 2a tanh((0.8 − T b )/0.1)) (κ ≈ 10 −10 ). Global stiff phase (w = +1, ∼ 64 e-folds); solitonic cores (1.1–1.8 kpc) via λ 6 ≈ 10 −94 . PBH seeds (M b ∼ 50 M ⊙ ) for JWST. Asymmetry η B,b ≈ 6 × 10 −10 via U 2 b -leptons. Eternal, singularity-free, fractal model predicts w b (z) deviations, void friction (δ void,b ∼ 0.02 ± 0.01), CMB asymmetries (δT /T b ∼ 10 −6 as dual-meta echo), neutrino drags (∆m 2b ∼ 0.05 eV 2 ) – testable with Euclid/DESI/LSST/DUNE/JWST (2025 updates: MicroBooNE rules out ∆m 2 ∼ 1 eV 2 , DESI H 0 = 68.53 ± 0.80 km/s/Mpc at 6σ tension).
