emerges as a direct consequence of tunneling interference and coarse-graining---offering a natural origin for primordial density perturbations without inflaton-induced fluctuations.
4. Addressing the Classical Problems of the Early Universe
This positions the model within a new class of early-universe theories: ones that emerge from quantum information dynamics rather than scalar fields or classical GR breakdowns.
5. Observable Consequences
A structured-tunneling cosmogenesis scenario leads to novel signatures:
Primordial anisotropies that are directionally correlated due to phase entanglement at the tunneling boundary (explaining CMB anomalies),
A blue tilt or scale-dependent ns(k)n_s(k) in the power spectrum at small scales, potentially matching JWST high-redshift data,
Echoes in the gravitational wave spectrum, corresponding to interlayer boundaries where spacetime refractive indices change.
These are testable with missions like Planck (archival), JWST, Euclid, LISA, and SKA.
In summary, structured tunneling provides a self-contained, quantum-originated alternative to both the Big Bang singularity and inflation, embedding:
Fractal structure from the onset,
Holographic cross-layer information flow, and
A universe without singularities or fine-tuned fields, yet with falsifiable and unique predictions.
D. Experimental Constraints: Strong Lensing, Redshift Drift, and Tensor Mode Forecasts
1. Importance of Empirical Constraints in Post-CDM Frameworks
For a theoretical cosmological framework to be viable, it must yield falsifiable predictions and withstand empirical scrutiny. While the proposed model integrates layered topology, fractal geometry, and holographic constraints, it must still conform to precision cosmology datasets, particularly where CDM is most successful.
