In this talk I discuss about the recent attempts, difficulties and prospects of explaining the cosmic inflation and the current acceleration of the universe (attributed to cosmological vacuum energy) using explicit cosmological solutions of five- and ten-dimensional warped supergravity models. These solutions correspond to the dimensional reduction to 4 dimensions of the 10D supergravity models, where the spacetime is a warped product of a six-dimensional Einstein space and dS4.
