Assessment

Why?

Strongest counted support: LHAASO reports stacked very-high-energy gamma-ray emission from five nearby giant molecular clouds over 4.5 years, consistent with cosmic-ray interactions across 1–100 TeV. weight 2.000000 evidence

Suppressed as dependent: The passage directly reports the five-cloud stacked detection, 4.5-year observation span, and 1–100 TeV cosmic-ray consistency.; The Nature Astronomy study reports LHAASO’s 4.5-year stacked detection of very-high-energy gamma rays from five nearby giant molecular clouds, with 1–100 TeV spectra consistent with cosmic-ray interactions with interstellar matter.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

  Primary article directly matches every observational element in the claim.

Evidence against

None.

Qualifications

• The underlying analysis found no individually significant excess in any cloud and relied on stacking to detect weak aggregate emission.

  This does not negate the stated stacked result, but materially limits interpreting it as five separately significant cloud detections.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
