WebFor a positively curved Universe, the expansion halts when it cancels the matter density term and a contraction phase begins. The presence of a cosmological constant, which is independent of scale factor, changes this a little. A flat or negatively curved Universe ultimately enters an exponential expansion phase driven by the cosmological constant.
