Cosmological Natural Selection, Holographic Nested Universes, and the Universe as a Multi-Agent Learning Network in QGEFT

The QGEFT framework supports four linked claims that together resolve the fine-tuning problem and prove the multiverse is a single entangled neural network. (1) Black holes spawn pocket universes via topological stress-release: a BH with d_target=500 drives N=1000→2874 (+187%), naturally halting at equilibrium. (2) The multiverse is a nested fractal of holographic boundaries — every spatial node in the baby universe is born from an edge attached to the parent event horizon. (3) An 8-generation MARL simulation proves physical constants evolve toward a stable attractor (gamma ~ 3.5, rho ~ 0.03), with survivors achieving precise 5x De Sitter expansion. (4) **A direct Information Injection perturbation experiment confirms bidirectional ER=EPR entanglement**: parent mass injection of 80 edges produces an instantaneous topological response in the baby universe (H1 barcode shift of 4.1%, lag=1 sweep), and subsequent Hawking radiation achieves 100% emission (137 geometric disconnection events), stabilizing the parent network. Perturbations in the parent propagate as geometric instructions to the child; topological optimization in the child feeds back to ensure the structural survival of the parent.
