Binary Cosmogenesis: A Two-Parent Extension of Black-Hole Cosmology, with Baryon Asymmetry Seeded by the Chirality of the Parental Merger

We explore a speculative extension of black-hole cosmology in which daughter universes are associated with binary black-hole mergers rather than (or in addition to) single collapses. Because the bounce mechanism fires at collapse, each progenitor has already produced a daughter before merging; we interpret horizon fusion as the joining of the two daughters’ throats — a junction we conjecture itself reaches bounce conditions — yielding a genuinely two-parent child. We conjecture that the net chirality of the fusing region sets the initial kick of a rolling pseudoscalar in the child; tensor modes produced during the child’s own inflation are then helicity-biased, and the gravitational-anomaly leptogenesis of Alexander, Peskin and Sheikh-Jabbari converts the bias into the child’s baryon asymmetry. Sterility has two ends: the symmetric corner (identical parents) and the extreme-mass-ratio corner (vanishing partner), each for independent structural reasons, with fertility occupying a band between them. The framework’s falsifiable commitment is a predicted correlation between otherwise independent sky anomalies (galaxy-rotation asymmetry; cosmic birefringence). We provide a frank novelty audit and state the principal unresolved objections, including the conditions a gauge-invariant definition of the chiral carrier must satisfy.
