A Classical, Non-Singular Bounce

Bouncing cosmological models offer a viable alternative to Big-Bang cosmology and have gained recent attention. In a bouncing cosmology, the universe is initially contracting towards a minimum size before expanding. Such cosmological models are geodesically complete by construction and offer simple solutions to problems such as the Horizon problem. I will present a model that realizes such a cosmology and discuss its analytical and numerical properties. I will also discuss ongoing work on the stability of cosmological perturbations and possible future directions.
