Black Hole Cosmology with Selective Permeability: A Biological Approach to Multiverse Structure

This preprint proposes a novel cosmological framework extending black hole cosmology (Poplawski 2010-2023) and cosmological natural selection (Smolin 1992-1997) through systematic application of biological principles. The theory introduces four major innovations not found in existing literature: (1) selective permeability of event horizons based on particle interaction cross-sections, (2) dark matter as continuous influx from parent universe, (3) discrete fertility/sterility of universes determined by fundamental constants, and (4) network (mycelium) rather than tree structure of multiverse. Core hypothesis: Our universe exists inside a black hole in a parent universe. The event horizon functions as a selectively permeable membrane—analogous to biological cell membranes—allowing weakly-interacting particles (dark matter) while blocking strongly-interacting matter (baryons). This naturally explains dark matter's uniform distribution and provides testable predictions. Key distinctions from existing theories:- vs Smolin: Discrete fertility/sterility, inheritance vs evolution, selective membrane- vs Poplawski: Selective permeability, dark matter influx, fertility criteria- vs Standard paradigm: Physical (not computational) membrane with particle selectivity Novelty: Systematic literature search (ArXiv, Google Scholar, Zenodo, December 2024) confirms 4 of 10 core concepts are completely novel, with remaining concepts representing significant original perspectives. Overall originality: 70%. Status: Early-stage theoretical framework requiring mathematical formalization. Author welcomes feedback and collaboration.
