The recollapsing model predicts that the expansion of the universe will eventually slow down and reverse, causing galaxies to get closer together and leading to a collapse of the universe. The other models (accelerating, coasting, and critical) do not predict a collapse, and instead suggest that the universe will continue to expand indefinitely.
