The A–AB–B Framework: Potentia, Local Big-Bang–Like Transitions, and the Emergence of Observable Universes

This work presents an updated and extended version of the A–AB–B framework, a conceptual and axiomatic cosmological model in which observable universes (B) emerge from localized big-bang–like transitions (AB) within a deeper, non-spatiotemporal physical domain referred to as A (Potentia). The framework does not assume a classical multiverse of independent bubbles, but a single fundamental background in which multiple universes may form, coexist, decay, or reproduce depending on local physical conditions. The theory is formulated with minimal mathematical structure, emphasizes falsifiability through indirect observational signatures, and aims to remain fully compatible with known local physics. This version incorporates updated hypotheses regarding the nature of AB transitions, the role of extreme density states (e.g. black-hole interiors as AB-favoring conditions), cosmic anisotropies, supermassive black holes at high redshift, and large-scale rotational alignments (Axis of Evil). The work is intended as a conceptual preprint inviting critical analysis rather than as a finalized physical model.
