Chapter 47: Galaxies as Life Basins: The SMBH Anchor

A Life basin is a spatial region whose internal Life dynamics are anchored by a central structure; galaxies are the canonical cosmological Life basin. The carrier ladder X_gal[n] organizes carriers from molecular to galactic scale into a hierarchy that inherits basin constraints from above. The basin predicate D^bas_n specifies admissibility conditions for a galaxy to function as a Life basin: the central SMBH must itself satisfy Distinction and SelfDesc. The Galaxy–SMBH Anchor Lemma shows that code(D^gal)[ω] factors through code(D^SMBH)[ω], so the galactic ω-germ is determined by the central SMBH’s ω-code. Galaxy merger drives basin restructuring through SMBH merger and lineage-code-stream fusion.
