An alternative to inflation: matter bounce cosmology
In this talk, I will introduce the basic idea of matter bounce and its specific realization by applying a Lee-Wick scalar in the early universe. As an alternative to inflation, matter bounce can give a scale-invariant spectrum required by CMB observations as inflation did. Moreover, it predicts large and negative non-gaussianities which are expected to be detected or ruled out by near future observations.
