We show that the requirement of contractability and smoothness of certain 4-manifolds representing the cosmic evolution restricts the possible spatial models. In particular certain models like the Poincare sphere are excluded. Turning to the case of a fake it is argued that the inflation can be explained by the exotic smooth structure of this 4-manifold. Finally, we discuss the exotic R 4 to which we assign a gravitational instanton.
