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
Magnetic confinementenablesNuclear fusionEstablished
Magnetic Confinement enables Nuclear Fusion.
Mechanism: Confining the plasma long enough at high temperature and density lets fusion reactions proceed.
Enables · leads to
Nuclear fusioncausesEnergyEstablished
nuclear fusion causes Energy.
Mechanism: Fusing light nuclei releases enormous energy — the process that powers the Sun.

Nucleosynthesisdepends onNuclear fusionEstablished
nucleosynthesis depends on nuclear fusion.
Mechanism: Nucleosynthesis builds heavier elements by fusing lighter nuclei — in the Big Bang and in stars.

Stardepends onNuclear fusionEstablished
star depends on nuclear fusion.
Mechanism: A star shines because nuclear fusion in its core turns hydrogen into helium, releasing enormous energy.

System context
Fusion ignitionis part ofNuclear fusionEstablished
Ignition is a fusion milestone.
Mechanism: Ignition is the point where a fusion burn becomes self-sustaining and returns net energy to the fuel.
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 · 9 of 9 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: 9 → 47 → 125 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Strengths
- Redundantly connected — removing it leaves the sampled cross-field routes unchanged. structural
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

What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
2 concepts build on this directly, 4 in total, across 2 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
