I review two cosmological paradigms which are alternative to the current inflationary scenario. The first alternative is the "matter bounce", a non-singular bouncing cosmology with a matter-dominated phase of contraction. The second is an "emergent" scenario, which can be implemented in the context of "string gas cosmology". I will compare these scenarios with the inflationary one and demonstrate that all three lead to an approximately scale-invariant spectrum of cosmological perturbations.

  1. Emergent Universe in f(Q) gravity theories

    gr-qc 2024-12 reject novelty 5.0 of 10

    In a specific f(Q) gravity model, Einstein static universes with oscillatory stability exist for certain matter equations of state, but the claimed transition to inflation is constructed ad hoc.
