  A cosmological model for the early time Universe is proposed. In this model,
the Universe is a wandering brane moving in a warped throat of a Calabi-Yau
space. A non-zero angular momentum induces a turning point in the brane
trajectory, and leads to a bouncing cosmology as experienced by an observer
living on the brane. The Universe undergoes a decelerated contraction followed
by an accelerating expansion and no big-bang singularity. Although the number
of e-folds of accelerated motion is low (less than 2), standard cosmological
problems are not present in our model thanks to the absence of an initial
singularity and the violation of energy conditions of mirage matter at high
energies. Density perturbations are also calculated in our model and we find a
slightly red spectral index with negligible tensorial perturbations in
compatibility with WMAP data.
