I'm referring to the overall spacetime curvature shared by the universe as a whole.

Sorry, out of my depth.
- pdonis 13y agoI'm referring to the overall spacetime curvature shared by the universe as a whole. Then that's positive, not negative, for a spacetime dominated by dark energy. The curvature that is negative is the curvature of the spatial slices in the model used in cosmology for a dark energy dominated universe--more precisely, in the model referred to in the article as being suggested by the new data.
