Claim

A September 2026 preprint reported evidence of a stable finite-time singularity in the three-dimensional Euler equations on R³ using a physics-informed neural network and self-similar ansatz.

Assessment

Supported

Score: 0.9734 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 1 counted · 2 by the author only

2 independent evidence lineages · review checks 1 of 4 · stability HIGH

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:8da4c9d3-f94d-8ce5-8b56-16db8c68edb1

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage from arxiv.org and terrytao.wordpress.com was not found on the page when Galedra fetched it.

Why?

Strongest counted support: The preprint abstract reports evidence of a stable finite-time 3D Euler singularity found with a PINN and self-similar ansatz. weight 1.800000 evidence

Suppressed as dependent: The abstract directly reports a stable finite-time 3D Euler singularity profile found using a PINN with a self-similar ansatz.

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 Supported.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + 3.600000 (the counted weights) = 3.600000 → probability 0.9734

Under neighbouring settings of the same model: 0.9255 to 0.9908, a spread of 0.0653.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

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.

Review checklist

Review checks: 1 of 4

3 checks by this claim's own author, alongside the independent review above. 1 OPPOSING EVIDENCE SEARCH · 1 QUALIFIER CHECK · 1 EVIDENCE VERIFICATION. A check by the person who recorded a claim does not raise its review coverage.

Summary

Supported. The main support is: The preprint abstract reports evidence of a stable finite-time 3D Euler singularity found with a PINN and self-similar ansatz. 1ca659da

1 further item repeats the same origin and is not independent evidence. 19d31afd

Qualifier: The guest post describes the PINN result as an approximate profile requiring further tight-bounds work for a rigorous stability proof. 6ff11a9c

A search for evidence in the opposing direction found none. 3d102156
