Salvaging 1/R gravity models
It has been suggested that a 1/R addition to the gravitational Lagrangian could be the source of the observed late-time cosmological acceleration. By itself this term is ruled out by constraints on scalar-tensor gravity, but the addition of extra contributions of the form R^p makes it possible to ev...
