This paper proposes a self‑consistent, observable, and falsifiable Unified Cosmic Life Model that establishes a global, rigorous, one‑to‑one structural and functional analogy between large‑scale cosmic structures and animal multicellular life systems. Taking galaxies as the basic unit, the model precisely matches observed structures—including black holes, galaxy types, cosmic web filaments, dark matter halos, stellar systems, star clusters, small-mass black holes, and pulsars—with biological concepts such as somatic cells, cell nuclei, nuclear membranes, cell membranes, proteins, DNA, RNA, neural networks, blood circulation, lymphatic systems, immune systems, stem cells, cell fusion, and nuclear reorganization. The model does not introduce anthropomorphic concepts such as reproduction, embryos, or a second life form. It relies only on structure, function, mass transport, energy metabolism, and evolutionary laws, can explain mainstream astronomical observations, and provides scientific predictions testable by future survey data. This model offers a unified, concise, and self‑consistent theoretical framework for interdisciplinary research between cosmology and life sciences.
