Independent educational guide. Not affiliated with or endorsed by the universities, professors or laboratories described here. This collection reflects the material currently mapped on Socratic Learn.
Research using string theory, geometry, duality, black-hole physics and quantum-gravity consistency to understand which effective theories can arise from quantum gravity and what those constraints might imply for particle physics and cosmology.

Strings, Geometry, and the Swampland
The Dark Dimension: can dark energy point to an extra dimension?Explain the conditional argument for a micron-scale Dark Dimension and its KK tower.
Supports: Dark dimension
Strings, Geometry, and the Swampland
From quantum-gravity consistency to testable cosmologyTrace how a varying compactification radius can produce phenomenological predictions.
Supports: Dark dimension
JHEP 02:022 · 2023
M. Montero, C. Vafa, I. Valenzuela
Why this matters: Combines small observed dark energy, conjectural inputs and bounds into a proposed micron-scale dimension; no dimension is detected.
DOI: 10.1007/JHEP02(2023)022
JHEP 11:109 · 2023
E. Gonzalo, M. Montero, G. Obied, C. Vafa
Why this matters: Explores a KK graviton tower as a candidate dark-matter sector, conditional on the scenario and production assumptions.
arXiv preprint (no journal version listed) · 2024
C. Vafa
Why this matters: Discusses proposed scale relations and dark-sector connections. Relations in a model are not measurements.
Phys. Rev. D 111:046014 · 2025
J. J. Heckman, C. Vafa, T. Weigand, F. Xu
Why this matters: Combines conditional GUT and gravity assumptions with particle and proton-lifetime constraints to derive testable predictions.
DOI: 10.1103/PhysRevD.111.046014
Accepted for publication, Phys. Rev. D; arXiv v3 May 2026 · 2025
A. Bedroya, G. Obied, C. Vafa, D. H. Wu
Why this matters: Models evolving energy and dark-matter masses. A comparable cosmological fit does not establish the microscopic Dark Dimension explanation.
