Transient Topological Intersections: Wormholes as "Tree Branches" in a Nested Multiverse

This paper proposes a novel framework for understanding theoretical wormholes not as intra-universe shortcuts, but as temporary topological intersections between distinct, expanding child universes. Expanding upon the Evolutionary Superfluid Cosmology hypothesis—wherein stellar-mass and supermassive black holes initiate causally disconnected universes via localized singularity bounces—we postulate that expanding child universes may experience boundary interactions. We propose two distinct formation mechanics for these intersections: Type I (Merger-Induced) resulting from binary black hole collisions, and Type II (Strain-Induced) resulting from the non-local fracturing of the parent universe's superfluid vacuum under extreme inflationary pressure. Both interactions create transient bridges analogous to metaphorical "tree branches." Driven by the inherent cosmological constants of each respective universe, mutual expansion forces inevitably stretch and sever these connections. We provide mathematical formulations for the scale factors, formation conditions, throat decay, and temporal lifespan of these structures.
