Why Are Lifeless Planets Desolate? Life as the Emergent Knot of Environmental Activity
Life emerges when interactions persist long enough to reinforce and reorganize themselves. Here, I propose relational persistence (R) as a conceptual measure of an environment’s ability to sustain interactions beyond dissipation, summarizing five factors—encounter, maintenance, memory, reinforcement, and network expansion—that together determine whether chemical and physical relationships can accumulate into a self-maintaining organization. When these factors collectively exceed a threshold (R > 1), interactions become persistent, enabling the transition from transient chemistry to lifelike structure. This essay proposes a conceptual framework for understanding the emergence of life, rather than a quantitative model, and from this perspective, lifeless planets remain barren not because they lack chemical activity, but because their environments fail to sustain persistent relationships. This relational view suggests experimentally and observationally testable avenues in prebiotic chemistry and astrobiology, including enhanced network lifetimes, pattern retention, and emergent organization in structured, cyclic, and gradient-rich environments. Life may thus be understood as the first system in Earth’s history in which R exceeded 1—the first environment capable of sustaining and extending its own relationships.
