This preprint proposes a unified geometric framework in which the Schwarzschild singularity of a black hole in a parent universe resolves into the t=0 hypersurface of a new, causally disconnected flat FLRW baby universe. Infalling mass adds structure to a "dense region of time" at the bounce, seeding a geometric entropy gradient that naturally generates the thermodynamic arrow of time without fine-tuning. Black-hole mergers produce a shared t=0 hypersurface; parent histories remain classically indistinguishable near the bounce but acquire quantum superposition and probabilistic switching farther out. Minisuperspace quantization via the Wheeler–DeWitt equation yields a smooth wavefunction near the bounce transitioning to oscillatory behavior at large scale factor. Merger-induced overlap suppresses quantum fluctuations on long-wavelength modes, producing a low-k cutoff in the primordial power spectrum. After inflation, this predicts suppression of CMB temperature power at large angular scales (ℓ ≲ 30), with transition around ℓ ≈ 20–30 and depth scaling with parent merger asymmetry. The predicted spectrum matches the persistent low-ℓ TT anomaly in the Planck 2018 Commander data significantly better than baseline ΛCDM. The model requires no additional parameters and offers falsifiable predictions for tensor modes and parity asymmetry.
