Abstract

We have recently proposed a Lorentz-violating energy-momentum relation entailing an exact momentum cutoff and studied various physical applications of that dispersion law. By a simple phenomenological approach we study Lorentz violation effects on early Universe and pre-Planckian cosmological radiation. In particular, we predict an effective infinite speed of light soon after the big bang, leading to a possible solution of the horizon and flatness problems without recourse to inflation, cosmological scalar fields, or other ad hoc energy sources.
