Quizplus · Accepted Answer

In an open Universe model, the gravity of the Universe is not sufficient to stop the current expansion, and therefore, the galaxies will continue to fly apart forever. In a closed Universe model, the gravity of the Universe will eventually stop the expansion and pull everything back together in a "Big Crunch." An infinite Universe model simply suggests that the Universe is infinitely large and has no edges or boundaries. A cyclical Universe model suggests that the Universe goes through a cycle of expansion and contraction, with a Big Bang followed by a Big Crunch, and then a new Big Bang again.
