We consider ``brane-universes'', where matter is confined to four-dimensional hypersurfaces (three-branes) whereas one extra compact dimension is felt by gravity only. We show that the cosmology of such branes is definitely different from standard cosmology and identify the reasons behind this difference. We give a new class of exact solutions with a constant five-dimensional radius and cosmologically evolving brane. We discuss various consequences.

  1. Cosmological tensions in Proca-Nuevo theory

    hep-th 2025-11 conditional novelty 6.0 of 10

    Fitting a one-parameter vector-tensor dark energy model to CMB, BAO, and supernova data reduces the Hubble tension to about 1.5–2σ, but the preference over ΛCDM is weak and disappears once full perturbations are included.

  2. Unifying Cosmic Epochs via Quantum-Corrected Expansion with Brane-World Parallels

    hep-th 2025-05 reject novelty 4.0 of 10

    A single analytical scale factor with sigmoid-smoothed parameters is proposed to interpolate between inflation, radiation, matter, and dark-energy epochs.
