We consider whether current notions about superstring theory below the Planck scale are compatible with cosmology. We find that the anticipated form for the dilaton interaction creates a serious roadblock for inflation and makes it unlikely that the universe ever reaches a state with zero cosmological constant and time-independent gravitational constant.

  1. Curvature-Assisted Dynamical Compactification in a Pre-Inflationary Higher-Dimensional Universe

    hep-th 2026-04 unverdicted novelty 6.0

    Negative curvature sustains tracker-like radion evolution in a 5D open FRW universe, enabling trapping into a compactified vacuum via Casimir and Kaluza-Klein thermal effects before 4D inflation dilutes curvature remnants.

  2. Dynamical system analysis of the cosmological phases in Palatini $k$-essence gravity

    gr-qc 2025-11 unverdicted novelty 5.0

    Dynamical systems analysis of a Palatini k-essence model identifies fixed points for quasi-de-Sitter epochs, scaling solutions, and quintessence phases connected by heteroclinic orbits in flat FLRW cosmology.
