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
Planet formationdepends onAccretionEstablished
Planets form by accretion.
Mechanism: Dust grains stick and grow into planetesimals that gravitationally accrete more material into protoplanets and planets.
Planet formationdepends onProtoplanetary diskEstablished
Planets form within a protoplanetary disk.
Mechanism: The rotating disk of gas and dust around a young star supplies the material and the flattened geometry in which planets assemble.

Planet formationcausesPlanetEstablished
Planets form from a young star's disc.
Mechanism: Dust and gas orbiting a new star clump together and sweep their paths clear to become planets.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 1 concept; following enables/causes relations, 1 concept is downstream across 1 discipline.
structural · Follows only enables/causes dependency edges — not general relatedness.
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 2 foundations (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 3 → 12 → 54 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

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 2 foundation relations. 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 Protoplanetary disk and Accretion.
Through this lens it connects to Planet and Protoplanetary disk.
