We examine the cosmology of the two recently proposed scenarios for a five dimensional universe with localized gravity. We find that the scenario with a non-compact fifth dimension is potentially viable, while the scenario which might solve the hierarchy problem predicts a contracting universe, leading to a variety of cosmological problems.

  1. Suppressing Extra-Dimensional Axion Isocurvature Dynamically

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Radion dynamics in warped 5D models enhance the axion decay constant during inflation, satisfying CMB isocurvature bounds at higher Hubble scales while restoring the QCD window afterward.

  2. Inflation with a Growing Fifth Dimension

    hep-th 2025-12 conditional novelty 6.0 of 10

    Inflation from a UV-brane inflaton in a warped 5D bulk with an IR brane predicts a blue-tilted low-k scalar spectrum and oscillating tensor features because the early adiabatic modes come from the radion.

  3. Helical phase inflation and its observational constraints

    hep-ph 2019-08 conditional novelty 5.0 of 10

    Helical phase inflation, using the phase of a complex scalar as the inflaton, fits Planck 2018 and BICEP2 data and is claimed to show alpha-attractor behavior, with a brane version that reduces field excursions.
