Geometrically, it is easy to see how inflation can remove any initial curvature to spacetime (at least within the horizon). But remember that the geometry of spacetime is tied up with the density of the Universe. We call this W (Omega) and set it equal to 1 if it has the critical value. If inflation is correct, then we must have W =1, and the question becomes: how is that accomplished? We know that matter can only supply W =0.05, and dark matter gives about
