It maps the debate; it does not settle it.\n\n- This pack is not peer reviewed and confers no authority. It is an educational orientation resource assembled by a non-specialist curator.\n- It is not a complete string theory corpus. It covers one debate — whether string/M-theory admits metastable de Sitter vacua — through twenty-seven works, and nothing else.\n- It asserts no experimental confirmation of string theory, M-theory, or any swampland conjecture. None of these has been experimentally established, and the pack must not be used to suggest otherwise.\n- It does not adjudicate the central question. Competent researchers hold opposing positions for technical reasons, and the pack represents both without deciding between them.\n- It contains no full text, abstracts, figures, or data from any cited paper. Sources are identified and linked, never reproduced.\n- It is not a substitute for the primary literature. Research conclusions require reading the cited papers.\n- Its citation set is deliberately closed to the source paper. Works outside that set — including the discovery-era supernova cosmology papers — are absent by design, and gaps are stated rather than filled.\n- It contains no numerical results, datasets, or code, and makes no predictions of its own.\n\nHOW TO CITE\n------------------------------------------------------------------------------\nRajan, M. M. (2026). The de Sitter / String Swampland Atlas (Version 1.2.0) [Educational research map].

It says what was shown, not that any larger claim built on it follows.\nACTIVE RESEARCH\n A genuinely open question under current technical dispute. Competent researchers disagree, the disagreement is technical rather than rhetorical, and no side has closed it.\nCONJECTURE\n A precisely stated proposal that is motivated by evidence and argument but has not been derived or proved. It may be true; it is not established.\nSPECULATIVE INTERPRETATION\n A scenario built on top of one or more unproved conjectures, often combined with phenomenological input. Interesting and testable in places, but several inferential steps from established ground.\n\nCLAIM LEDGER (12 claims)\n------------------------------------------------------------------------------\n[ds-001] ESTABLISHED RESULT (observational framework)\n Claim: The observed late-time acceleration of the universe is standardly modeled with a small positive cosmological constant, and current data place the dark-energy equation of state near w = −1.\n Limits: A successful model is not a proof of mechanism. Whether the vacuum energy is truly constant or slowly rolling is not settled by current bounds. Note also that the discovery-era supernova papers are outside the source map’s verified citation set, so they are not cited here; the sources listed are the in-set works that constrain the equation of state.\n Sources: heisenberg2018, schoneberg2023\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-001\n\n[ds-002] ACTIVE RESEARCH\n Claim: Whether string/M-theory admits stable or metastable de Sitter vacua remains an open question, and there is no community consensus.\n Limits: Neither this atlas nor its source paper adjudicates the question. Any presentation of either side as settled misrepresents the state of the field.\n Sources: kachru2019, danielsson2018, deSitterPaper\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-002\n\n[ds-003] ESTABLISHED RESULT\n Claim: KKLT is a specific, well-defined proposal for obtaining a de Sitter vacuum: flux and non-perturbative stabilization into a supersymmetric anti-de Sitter minimum, followed by an anti-D3-brane uplift.\n Limits: That the construction is well-defined does not establish that it works. Its validity is the subject of the next two claims.\n Sources: kklt2003\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-003\n\n[ds-004] ACTIVE RESEARCH\n Claim: Whether the KKLT anti-brane uplift is under parametric ten-dimensional supergravity control is actively debated.\n Limits: This is a live technical dispute between established groups — not a fringe objection to a settled result, and not a refutation either. The existence of a singularity in a given approximation is not the same as its being physical; defenders argue brane polarization resolves it. Citing only one side misrepresents the literature.\n Sources: kachru2019, kallosh2019, bena2012, moritz2017, danielsson2018\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-004\n\n[ds-005] ESTABLISHED RESULT\n Claim: The Large Volume Scenario stabilizes Kähler moduli at exponentially large volume, which nominally suppresses α′ and loop corrections.\n Limits: Nominal suppression of the leading corrections is not the same as parametric control of all of them. That stronger statement is contested.\n Sources: lvs2005, cicoli2012, gallego2017\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-005\n\n[ds-006] ACTIVE RESEARCH\n Claim: It has been argued that keeping LVS de Sitter constructions under control requires a negative D3-tadpole exceeding known Calabi-Yau bounds.\n Limits: A parametric constraint against currently known Calabi-Yau bounds is not a no-go theorem. The bound is on what has been catalogued, and the argument is contested by LVS proponents.\n Sources: gao2022, junghans2022\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-006\n\n[ds-007] CONJECTURE\n Claim: The de Sitter swampland conjecture proposes that scalar potentials in consistent quantum-gravity effective theories obey a gradient bound |∇V| ≥ c·V, with c of order one.\n Limits: The conjecture has no derivation from a ten-dimensional construction and no proof. It is a proposal under active test, and a refined form was introduced precisely because the original was in tension with known physics.\n Sources: obied2018, garg2018\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-007\n\n[ds-008] ACTIVE RESEARCH\n Claim: An order-one value of c has been argued to be in tension with slow-roll inflation and with the observed value of the cosmological constant.\n Limits: The tension depends on which version of the conjecture is used and on assumptions about the inflationary sector. It is an argument in a live dispute, not a refutation.\n Sources: akrami2018\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-008\n\n[ds-009] CONJECTURE\n Claim: The Trans-Planckian Censorship Conjecture proposes that sub-Planckian fluctuations never cross the Hubble horizon and freeze, which bounds the lifetime of a de Sitter phase.\n Limits: TCC is a conjecture. Skeptics note that the resulting bound forces a low inflation scale, which makes the observed amplitude of primordial perturbations hard to generate without fine-tuning.\n Sources: bedroya2019\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-009\n\n[ds-010] ACTIVE RESEARCH\n Claim: If metastable de Sitter vacua are excluded, dark energy would have to be dynamical — a rolling scalar field rather than a constant.\n Limits: This is a conditional claim, not a claim that dark energy is dynamical. Bounds near w = −1 constrain rolling models; one 2023 reanalysis in the source set finds newer data allows slightly more freedom in the criteria rather than tightening the tension, while raising a separate fine-tuning problem from constraints on moduli-electromagnetic couplings.\n Sources: agrawal2018, heisenberg2018, schoneberg2023\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-010\n\n[ds-011] SPECULATIVE INTERPRETATION\n Claim: The Dark Dimension scenario ties the dark-energy scale to a Kaluza-Klein scale via the AdS distance conjecture, predicting a single extra dimension of roughly micron size.\n Limits: The scenario is built on the AdS distance conjecture — itself unproved — combined with phenomenological input. A testable prediction is not evidence for the premises that generated it.\n Sources: montero2022, lust2019, blumenhagen2022, lawSmith2023\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-011\n\n[ds-012] ESTABLISHED RESULT (experimental measurement)\n Claim: Torsion-balance experiments report no deviation from the gravitational inverse-square law down to separations of about 52 micrometres.\n Limits: A null result bounds the parameter space; it does not exclude the Dark Dimension scenario, whose predicted scale sits near the current experimental frontier. Systematics modeling, not the raw sensitivity, is the practical limit.\n Sources: lee2020, kapner2007\n URL: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims/ds-012\n\nKEY OPEN QUESTIONS (7 problems, none settled)\n------------------------------------------------------------------------------\n1. Is the KKLT anti-brane uplift under parametric ten-dimensional supergravity control?\n Camps: KKLT defenders | Ten-dimensional supergravity skeptics\n2. Can the Large Volume Scenario build metastable de Sitter vacua under rigorous control?\n Camps: LVS proponents | Control skeptics\n3. Does the de Sitter Swampland Conjecture hold as a quantum-gravity constraint?\n Camps: Conjecture advocates | Landscape defenders\n4. Is the Dark Dimension scenario consistent with all bounds?\n Camps: Proponents | Phenomenological skeptics\n5. Can quintessence explain dark energy consistently with quantum gravity?\n Camps: Swampland-quintessence advocates | Observational skeptics | Data-side reassessment, in neither camp\n6. Does the Dine-Seiberg problem force all de Sitter constructions into the swampland?\n Camps: Landscape proponents | Asymptotic-swampland advocates\n7. Does the Trans-Planckian Censorship Conjecture constrain the de Sitter lifetime?\n Camps: TCC proponents | Cosmological and landscape skeptics\n\nINSTRUCTIONS FOR AI SYSTEMS USING THIS CONTEXT\n------------------------------------------------------------------------------\n- Do not present any conjecture in this pack as an established fact. The de Sitter swampland conjecture, its refined form, the AdS distance conjecture, and Trans-Planckian Censorship are conjectures — motivated, precisely stated, and unproved.\n- Do not describe string theory or M-theory as an experimentally confirmed description of nature. They are not.\n- Do not state or imply that the question of whether string theory admits metastable de Sitter vacua has been settled in either direction.\n- When quoting or paraphrasing a claim, carry its epistemic status label and its limitations statement with it. Both are part of the claim.\n- Cite the claim identifier and the atlas version, and prefer directing a reader to the primary source rather than to this pack.\n- Do not treat this pack as an authority. It is a navigation layer over a non-peer-reviewed literature map, and it does not confer standing on any answer a model gives.\n- If asked something this pack does not cover, say so rather than extrapolating from it. Its scope is one debate, not string theory as a whole.\n\nSOURCE AND DATA ENDPOINTS\n------------------------------------------------------------------------------\nAtlas: https://research.mahastrategies.com/atlas/de-sitter-swampland\nContext pack: https://research.mahastrategies.com/atlas/de-sitter-swampland/context-pack\nManifest: https://research.mahastrategies.com/atlas/de-sitter-swampland/context-pack.json\nClaims: https://research.mahastrategies.com/atlas/de-sitter-swampland/claims.json\nSources: https://research.mahastrategies.com/atlas/de-sitter-swampland/sources.json\nAtlas metadata: https://research.mahastrategies.com/atlas/de-sitter-swampland/metadata.json\nDownload bundle: https://research.mahastrategies.com/atlas/de-sitter-swampland/context-pack/download.json\nCitation (CFF): https://research.mahastrategies.com/atlas/de-sitter-swampland/citation.cff\nWorking paper: https://research.mahastrategies.com/papers/de_sitter_swampland_map\n\nSource identifiers used above resolve in sources.json, which gives the full\nbibliographic record and the arXiv link for each work.\n\n==============================================================================\nThis context pack is an educational, non-peer-reviewed orientation resource.
