Can Black Holes Give Birth to Successor Universes? A General-Relativistic Junction Test of LCF-113

Can gravitational collapse give rise to a new universe—and can that universe inherit information from the one that preceded it? LCF-113 investigates a fundamental possibility in cosmology: that black holes may serve as mechanisms of cosmological succession, through which restricted information survives gravitational collapse and contributes to the initial conditions of successor universes. The objective is to develop this hypothesis into a mathematically consistent physical framework capable of explaining not only how successor cosmologies could emerge, but whether their inherited conditions could influence the formation of the earliest cosmic structures. This investigation advances that objective through explicit calculations in general relativity, moving the original LCF-113 framework into the mathematical conditions governing gravitational collapse, cosmological evolution, and spacetime continuity. Five computational stages examine primordial perturbation sources, Einstein's gravitational constraint equations, closed-universe bounce solutions, and the geometric matching conditions required to connect a collapsing parent spacetime to a prospective successor cosmology. The principal calculation examines an Oppenheimer–Snyder collapsing dust interior matched to a closed radiation-plus-cosmological-constant universe. The results establish a decisive distinction between two possible gravitational connections. A smooth local geometric junction can be constructed between the collapsing parent interior and the contracting phase of the proposed successor universe, including configurations in which the parent boundary lies within a trapped region. The successor cosmology subsequently admits a smooth bounce into expansion. In contrast, direct smooth matching at the instant of the cosmological bounce fails the tested junction conditions. Together, these results establish a concrete mathematical route for investigating cosmological succession while excluding a simpler direct-bounce construction. The study identifies admissible gravitational configurations, determines their governing conditions, and establishes explicit boundaries within which a physical transition mechanism must operate. Additional calculations examine how inherited parameters could influence primordial perturbations, whether the proposed initial conditions satisfy Einstein's constraints, how cosmological bounce solutions depend on their governing parameters, and which proposed signatures can also arise from conventional source models. The investigation is supported by consolidated Python calculations and independent Wolfram Language implementations. Across the related LCF-113 injector-gate and physical-bridge investigations, all 2,233 recorded numerical verification checks passed, providing reproducible computational support for the tested mathematical results. The next stage is to derive the physical dynamics connecting gravitational collapse to cosmological succession, including matter conversion, globally consistent spacetime geometry, and the relationship between inherited information and the resulting cosmological structure. The central objective is to determine whether black-hole formation can produce physically consistent successor universes—and whether the large-scale structure of our own universe could retain measurable consequences of such an inheritance. LCF-113 approaches that question through a developing mathematical framework, explicit gravitational constructions, and reproducible computational tests, establishing a foundation for investigating cosmological inheritance as a physical process rather than a purely speculative possibility.
