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.

Every flat map introduces distortion
UnresolvedBecause no smooth isometric map exists from a sphere to a plane (Gauss, Theorema Egregium), every flat map distorts area, angle, or distance.
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
MathematicalWho makes the claim: Differential geometry; standard cartography references.Scope: See exact wording for scope and definitions; further scoping to follow with primary sources.
Flat / enclosed model
What it says: If the Earth is a plane, a 1:1 flat map is possible and distortion narratives conceal that possibility.
Required assumptions: coordinate-system
Strongest objection: Awaiting primary-source ingest.
Falsifier: A physically-produced 1:1 flat map validated against surveyed distances across two hemispheres without breaking angle, area, or distance simultaneously.
Globe model
What it says: All projections make explicit trade-offs recorded in cartographic references.
Required assumptions: coordinate-system
Strongest objection: Awaiting primary-source ingest.
Falsifier: A demonstrated flat map preserving all three of area, angle, and distance across the full sphere.
Circular-reasoning check
No circular-reasoning risks identified in the authored evidence chain.

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.
