# Spaceship Earth > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] provides the evolutionary and computational context for this supporting concept. **Domain:** Systems / Planetary Governance **Doc Type:** Supporting Canonical Node **Maturity:** Developed ## Definition Spaceship Earth is the framing of Earth as a materially bounded, interdependent life-support system whose inhabitants share finite resources and coupled consequences. ## Nexus Context The biosphere’s open-ended evolution still operates inside planetary energy and material constraints; digital ecologies likewise require resource accounting rather than fantasies of immaterial computation. ## Relationships [[wiki/Biosphere|Biosphere]], [[wiki/Systems Ecology|Systems Ecology]], [[wiki/Planetary Boundaries|Planetary Boundaries]], [[wiki/Resource Constraint|Resource Constraint]] ## Sources / Provenance - Developed from the cited research in the central article and the surrounding continuity, rights and evolutionary architecture.
