DESCRIPTION:We show that the current accelerated expansion of the Universe
  can be explained without resorting to dark energy. Models of generalized 
 modified gravity\, with inverse powers of the curvature can have late time
  accelerating attractors without conflicting with solar system experiments
 . We have solved the Friedman equations for the full dynamical range of th
 e evolution of the Universe. This allows us to perform a detailed analysis
  of Supernovae data in the context of such models that results in an excel
 lent fit. Hence\, inverse curvature gravity models represent an example of
  phenomenologically viable models in which the current acceleration of the
  Universe is driven by curvature instead of dark energy. If we further inc
 lude constraints on the current expansion rate of the Universe from the Hu
 bble Space Telescope and on the age of the Universe from globular clusters
 \, we obtain that the matter content of the Universe is 0.07 \n\nhttps://i
