    Nonextensive scalar field theories and dark energy models
    Current astronomical measurements indicate that approximately 73% of the universe is made up of dark energy. Stochastically quantized self-interacting scalar...

    Open questions and Non-Standard models
    I will review some theoretical ideas in Cosmology different to the standard "Big Bang": the Quasi-steady State model, Plasma Cosmology model, non-cosmological...

    Problems with the dark matter and dark energy hypotheses, and alternative ideas
    Two exotic elements have been introduced into the standard cosmological model: non-baryonic dark matter and dark energy. The success in converting a hypothesis...
