We present a complete theoretical framework demonstrating that rotating Kerr black holes naturally facilitate particle transitions between tiers of a quantized multiverse. The mechanism leverages the Kerr black hole’s unique geometry to create a catalytic “resonance zone” (rH < r ≤1.5M ). Within this zone, the intense gravity perturbs the fundamental meta-field , and general-relativistic effects like frame-dragging and gravitational time dilation dramatically enhance the probability of a particle transitioning between universe-tiers. This particle-level process is catalyzed by the black hole environment, with the transition energy scale set by the fundamental GUT-scale gap ΔE~1016 GeV. The model yields specific, falsifiable predictions, including anomalous ultra-high-energy cosmic rays—from protons to heavy nuclei—emanating from directions of spinning black holes. Predicted fluxes are consistent with observations from the Pierre Auger Observatory and Telescope Array when accounting for instrumental coverage and source distribution. Furthermore, the mechanism is inherently bidirectional, enabling the detection of particles from other tiers and opening the possibility for opening the possibility for paradox-free cross-temporal transitions between parallel tiers.

We propose a quantum multiverse model where universes are characterized by discrete energy levels ("tiers"), distinguished by quantum energy gaps and Hubble-scaled screening effects while sharing identical physical laws. Transitions between tiers, mediated by screened Yukawa interactions, drive cosmic evolution and generate distinct observational signatures. The model predicts a scale-invariant primordial power spectrum (n_s \approx 0.96) from inflationary transitions, high-frequency gravitational waves (\Omega_{GW} \sim\ {10}^{-15} at kHz) during reheating, and late-time phantom dark energy (w \approx -1.03) all of which are consistent with Planck and DESI 2024 data. The model provides a mechanism for baryogenesis via multiverse-mediated antimatter ejection, accounting for the observed matter-antimatter asymmetry (\eta \approx\ 6x{10}^{-10}), and unifies inflation, reheating, and dark energy through quantum transitions that preserve unitarity and the energy-time uncertainty principle. With testable predictions for CMB-S4, Einstein Telescope, and next-generation surveys, this work provides a compelling, falsifiable alternative to ΛCDM that bridges quantum mechanics and cosmology without fine-tuning.

We propose a paradigm shift in the understanding of dark matter. Rather than being an unknown particle, we demonstrate that the observed phenomenology of dark matter emerges naturally as an emergent gravitational phenomenon caused by the interaction between visible matter and a cosmic scalar field, the meta-field (Φ). This field is posited to define the fundamental energy tiers of a quantized multiverse. From an action principle featuring a non-minimal coupling ( ξR|Φ|^2) between the meta-field and spacetime curvature, we derive a modified Einstein equation. Its weak-field limit reveals that the interaction between visible matter and the meta-field sources an effective dark matter density: ρ_"DM" (r)=(16πGξv_0 )δΦ(r) ρ_"visible" (r), where δΦ is the meta-field perturbation. This relation predicts, without fine-tuning: The complete suppression of the dark matter effect in galactic centers due to the vanishing of the field perturbation (δΦ→0) in high-curvature regions; The strict absence of dark galaxies, as ρ_"DM" →0 where ρ_"visible" →0; and a mass-dependent gravitational coupling G_"eff" , offering a unified solution to the observed paucity of dwarf galaxies and the core-cusp problem, which is resolved by the absence of any dark matter contribution to the central potential. Our model renders particle-based dark matter unnecessary, replacing it with a novel interaction between known matter and the multiverse’s architecture, testable with next-generation astronomical surveys. This includes the definitive prediction that precise orbital measurements in galactic centers (e.g., of the S-stars around Sagittarius A*) will find no gravitational anomaly attributable to dark matter.

We propose a quantum multiverse model where universes are characterized by discrete energy levels ("tiers"), distinguished by quantum energy gaps and Hubble-scaled screening effects while sharing identical physical laws. Transitions between tiers, mediated by screened Yukawa interactions, drive cosmic evolution and generate distinct observational signatures. The model predicts a scale-invariant primordial power spectrum (n_s\approx0.96) from inflationary transitions, high-frequency gravitational waves (\mathrm{\Omega}_{GW}\sim{10}^{-15} at 1 kHz) during reheating, and late-time phantom dark energy (w\approx-1.03) all consistent with Planck and DESI 2024 data. Crucially, the framework resolves baryogenesis through multiverse-mediated antimatter ejection, yielding the observed matter-antimatter asymmetry ( \eta\approx6\times{10}^{-10} ), and unifies inflation, reheating, and dark energy through quantum transitions that preserve unitarity and the energy-time uncertainty principle. With testable predictions for CMB-S4, Einstein Telescope, and next-generation surveys, this work provides a compelling, falsifiable alternative to ΛCDM that bridges quantum mechanics and cosmology without fine-tuning.

We formulate a covariant effective framework in which a universe’s vacuum occupies discrete stationary states of a scalar meta-field Φ, structurally analogous to atomic energy levels. Each tier n carries a gravitating vacuum energy density and tier-dependent dimensional scales, c_n=c_0 e^(-α(n-30) ) and ℏ_n=ℏ_0 e^(+α(n-30) ), with α≃0.01. Consequently, ℏ_n c_n and, under the stated reference convention, the fine-structure constant remain invariant. The empirically calibrated spectrum ρ_vac^((n) )=10^(64-(111/29)(n-1) ) GeV^4 connects an inflation-compatible scale at n=1 to the observed order of the present vacuum-energy density at n=30. Within a fixed tier, the standard radiation- and matter-dominated background evolution is recovered; global transitions allow energy exchange between a universe and the multiverse while conserving total multiverse energy-momentum. Inflation, reheating, and late-time acceleration are thereby interpreted within the same quantized vacuum structure. We distinguish these global transitions from localized quantum conversion of a particle mode between universe sectors. This process is represented by a two-state Hamiltonian containing a postulated localized Hermitian off-diagonal gateway operator. In Kerr geometry, frame dragging provides the local energy and angular-momentum exchange needed to satisfy the resonance condition. For the benchmark transition U_31→U_32, the adjacent-tier electron energy release is 9.9181 keV. For an a_*=0.998 black hole and inward 1MeV electrons that are flux-isotropic in the local zero-angular-momentum frame, the Kerr resonance condition selects 0.271284% of the incident population. For eligible particles, the exact transition probability is P_(31→32)=sin^2⁡Θ. Under the additional benchmark assumption that the coherent phase is unresolved and uniformly sampled, ⟨P⟩=1/2, giving a conditional phase-averaged transition fraction of 0.135642%. The absolute transition normalization remains dependent on the postulated off-diagonal amplitude Γ(τ). Exact propagation of 4,194,304 photons emitted at r_*=1.30188M, outside the horizon and inside the ergosphere, yields a 4.72% escape fraction for electron-rest-frame isotropic emission. A local 9.9181 keV photon becomes a broad X-ray component with mean observed energy 3.95 keV and central 90% interval 0.88–6.93 keV. For a 10M_⊙ black hole at 8 kpc accreting at 0.1M ̇_Edd, using this phase-averaged benchmark the photon flux is 6.99×10^(-9) B cm^(-2) s^(-1), where B=f_q b_γ T_los. The calculated spectrum and its correlations with black-hole spin, mass, accretion rate, and distance define a falsifiable X-ray test. The framework thus converts a tiered-multiverse hypothesis into a quantitative model with explicit cosmological dynamics, transition probabilities, and observable strong-gravity signatures.
