Brane cosmology presents many interesting possibilities including: phantom acceleration (w<-1), self-acceleration, unification of dark energy with inflation, transient acceleration, loitering cosmology, new singularities at which the Hubble parameter remains finite, cosmic mimicry, etc. The existence of a time-like extra dimension can result in a singularity-free cyclic cosmology.

  1. An Alternative Approach to the Exact Solution of FRW-Type Spacetime with a Generalized Chaplygin Gas

    gr-qc 2025-02 reject novelty 3.0 of 10

    The claimed exact solution for a generalized Chaplygin gas universe is invalid because it only satisfies the starting equation when the matter constant equals the dark-energy constant, a condition the paper's own fits...
