Claim ds-002 · Atlas v1.2.0

Whether string/M-theory admits stable or metastable de Sitter vacua remains an open question, and there is no community consensus.

ds-002Active research

Whether string/M-theory admits stable or metastable de Sitter vacua remains an open question, and there is no community consensus.

Why it is stated this way
The source map is explicit that the disagreement is technical and genuine, turning on the validity of four-dimensional effective actions, the control of higher-dimensional backreaction, and the trustworthiness of asymptotic regimes. Both camps maintain mathematically sophisticated positions.
Scope and limitations
Neither this atlas nor its source paper adjudicates the question. Any presentation of either side as settled misrepresents the state of the field.

Why this source is here — The working paper this atlas is derived from. Cited where a claim rests on the paper’s own framing of the field rather than on a physics result — most directly the statement that no consensus exists.

This claim is one entry in an educational, non-peer-reviewed orientation tool. It is not a consensus statement, and its epistemic status label is part of the claim — quoting the wording without the status and the limitations misrepresents it.
