Sommario:
  • <p>We present a refined formulation of the Wave-3 framework in which spacetime is modeled as an emergent medium exhibiting fluctuation-driven corrections to a $\Lambda$CDM background. The model is restricted to phenomenologically supported components and formulated within an effective field theory (EFT) approach. A fluctuation tensor field with nonlinear self-interactions is introduced and coupled to the energy–momentum tensor, allowing external fields to influence the emergent structure of spacetime.</p> <p>Numerical simulations demonstrate that while uniform background fields produce weak, non-scaling corrections, spatially structured fields induce statistically significant and scale-dependent deviations from a red-noise spectrum. A sub-linear scaling relation of the form $|\Delta P| \propto \gamma^{0.41}$ is observed, indicating a nonlinear but stable response of the system. These results suggest that the structure of background fields, rather than their magnitude alone, plays a central role in generating large-scale correlations within an emergent spacetime medium.</p> <p>The framework remains consistent with General Relativity in the weak-fluctuation limit and is interpreted as an effective theory valid below a cutoff scale. No claim of a complete quantum gravity theory is made; instead, the model provides a testable phenomenological approach for exploring fluctuation-driven deviations from standard cosmological behavior.</p>
