Claim Evaluation
Every claim is stated exactly, traced to its origin, and evaluated against the best supporting and the best opposing case. Scientific claims must expose their full reasoning chain — observation, measurement, calculation, prediction, physical test, result, replication — and declare per-model predictions BEFORE the result is shown. Appeals to authority (“science says”, “experts agree”, “the math proves it”, “settled”) are not evidence. Confidence is authored, not tallied. Preserve disagreement rather than force a conclusion.
- Incomplete — primary sources not yet ingestedThe universal comparison scaffold below is a placeholder. Do not treat empty sections as evidence.
Sun path and the origin of seasons
UnresolvedThe seasonal variation of the sun's altitude and daylight length at a given latitude follows the pattern predicted by axial tilt of a rotating sphere orbiting the sun.
Origin: Topic acknowledged; primary sources not yet ingested into this record.
Best supporting case
Awaiting primary-source ingest before an authored comparison.
Best opposing case
Awaiting primary-source ingest before an authored comparison.
Evidence
Universal comparison · who claims what, and how each model explains it
ExperimentalWho makes the claim: Standard astronomical model; flat-earth counter-models propose a moving overhead sun.Scope: See exact wording for scope and definitions; further scoping to follow with primary sources.
Flat / enclosed model
What it says: A near-overhead sun on a plane produces the observed daylight pattern through varying orbital radius or brightness cone.
Required assumptions: celestial-distances
Strongest objection: Awaiting primary-source ingest.
Falsifier: Simultaneous daylight south of the Antarctic Circle during Southern-Hemisphere summer, inconsistent with a plane-model sun path.
Globe model
What it says: Axial tilt (23.4°) plus orbital motion produce the observed daylight, altitude, and polar-day patterns.
Required assumptions: celestial-distances
Strongest objection: Awaiting primary-source ingest.
Falsifier: A polar-day/night pattern that does not match the sphere prediction for the recorded date and latitude.

Confidence · not_rated
This record is a structural placeholder. Confidence will only be rated once primary sources and reasoning chain are authored.
Confidence is authored, not tallied. It reflects primary vs. secondary evidence, source independence, methodology, conflicts, and reproducibility — not the count of sources.
