Finding Earth 2.0
Exoearth evidence observatory · sensitivity

How much does the conclusion depend on the model?

The observatory recomputes the leading candidate set across declared ranking weights, climate boundaries, composition relations, atmospheric assumptions and direct-imaging trade cases.

What the analysis found

Some leaders are stable; some are choices in disguise

A ranking can look precise while depending strongly on its weights. The candidate-level view exposes the full rank interval and the ranges produced by supported physical models. Missing model support is shown as unsupported rather than converted into agreement.

A short bar can also mean the relevant model is unsupported; the text value carries that distinction. The ranges cover the implemented model menu, not every plausible model.

Solar-System falsification results and candidate model rank sensitivity
Rank spans cover five declared legacy weight menus. Climate, composition and HWO ranges cover only the implemented supported model sets.
