Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
Ocean worlddepends onSubsurface oceanEstablished
Dominated by water.
Mechanism: An ocean world's outer layers are mostly water, often as a subsurface ocean under ice.
System context
Enceladusis aOcean worldStrongly supported
Enceladus is an ocean world.
Mechanism: Cassini detected water-vapour plumes fed by a subsurface ocean, making Enceladus a confirmed ocean world.
Europais aOcean worldStrongly supported
Europa is an ocean world.
Mechanism: Beneath its icy crust Europa is thought to hold a global liquid-water ocean, the defining trait of an ocean world.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 3 → 6 → 15 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 3 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Subsurface ocean, Europa and Enceladus.
