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.

Phase of the moondepends onMoonEstablished

Open Phase of the moon →

phase of the moon depends on Moon.

Mechanism: The Moon's phase is the fraction of its sunlit half we can see; it depends on the Moon's position because only the Sun-facing side is ever lit.

Open Solar System →

Moon is part of Solar System.

Mechanism: The Moon is Earth's natural satellite within the Solar System, held in orbit by Earth's gravity.

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 · 2 of 2 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Structural neighbourhood: 2 → 12 → 28 concepts reachable within 3 hops.

    structural · Structural reach — being reachable is not the same as being understood.

  • All 2 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

  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

What builds on this

1 concept build on this directly, 1 in total, across 1 discipline.

Astronomy

Structural downstream reach along dependency edges — not a claim of historical necessity.

Seen through each discipline

How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.

Astronomy

Through this lens it connects to Solar System and Phase of the moon.

What it looks like

Concrete cases that make this idea recognisable in the real world.

A ball and a lamp

Hold a ball at arm's length under one bright lamp and turn around: the lit portion you see waxes and wanes exactly like moon phases — no shadow of your head involved, just the changing angle.

Check yourself

A quick check against a common misconception. Nothing is scored — picking the tempting-but-wrong answer just flags an idea worth revisiting.

Which statement is correct?

Common misconceptions

Moon phases are caused by Earth's shadow falling on the Moon.

That describes a lunar eclipse, which is rare. Phases come from geometry: we see different fractions of the Moon's sunlit half as it orbits Earth. The Moon is always half-lit by the Sun; only our viewing angle changes.

Concepts that look related but are not yet connected here — candidates for a connection to reason about, not established links.

The scientific picture
