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.
Enables · leads to
Accretion discdepends onGravityEstablished
accretion disc depends on gravity.
Mechanism: An accretion disc forms because of gravity: matter spiralling toward a massive object flattens into a spinning disc as it falls inward.

GravitycausesFree fallEstablished
gravity causes free fall.
Mechanism: Gravity causes free fall: with no other force acting, a body accelerates downward at the same rate regardless of its mass.
- Wikidata verifiedmoderate evidence
GravitycausesOrbitEstablished
gravity causes orbit.
Mechanism: Gravity causes orbits: a body's forward motion combined with the constant pull toward another mass bends its path into a closed loop rather than a straight line.

Orbital mechanicsdepends onGravityEstablished
Orbits are governed by gravity.
Mechanism: Engineers plan burns and paths so a spacecraft's speed and gravity balance into a stable orbit.
Projectile motiondepends onGravityEstablished
projectile motion depends on gravity.
Mechanism: Projectile motion is shaped by gravity: a thrown object moves steadily sideways while gravity curves its path into an arc downward.

System context
Escape velocityis part ofGravityEstablished
escape velocity is part of gravity.
Mechanism: Escape velocity is a property of gravity — the minimum speed a body needs to break free of a mass's gravitational pull without further propulsion.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 3 concepts; following enables/causes relations, 3 concepts are downstream across 3 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 10 of 10 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 10 → 28 → 62 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
- 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.
What builds on this
4 concepts build on this directly, 4 in total, across 5 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
