Black Hole Ignition: Bias-Triggered Universe Emergence and the Photon–Radiation Record_v1.2

Here we explore an alternative: the black hole (BH) ignition hypothesis. Instead of a unique, global creation event, universes are ignited when gravitational collapse accumulates sufficient matter and radiation at a central node (the classical singularity). This model is motivated by three strands: (i) the observed baryon-to-photon ratio ($\eta \approx 6 \times 10^{-10}$) and the enormous photon inventory in the CMB, (ii) quantum-gravity arguments that replace singularities with finite cores and allow bounce/nucleation behavior, and (iii) observational evidence that our universe shows no continual feed from a parent (CMB isotropy), favoring sealed, one-shot ignitions rather than persistent channels.
