Baryon Acoustic Oscillations, CMB Isotropy, and the Hubble Tension in an Emergent Topological Geometry Framework

This preprint proposes a reinterpretation of Baryon Acoustic Oscillations (BAO), Cosmic Microwave Background (CMB) isotropy, and the Hubble constant within an emergent geometry framework (TRUQC). Geometry is treated as a late-time, relationally stabilized regime rather than a fundamental structure. In this context, CMB isotropy reflects the freeze-out of large-scale coherence rather than primordial metric homogeneity. BAO are reinterpreted not as a rigid comoving standard ruler, but as fossil traces of a relaxation transition between pre-metric and metric phases of the cosmic network. This framework naturally accounts for the observed Hubble tension without invoking modifications to early-Universe physics, exotic dark energy, or additional particle species. The apparent discrepancy between CMB-inferred and late-time measurements of the Hubble constant is shown to arise from regime-dependent observables in an emergent spacetime.
