Explanation:
Detailed explanation-1: -To find out which is right, astronomers had to fast-forward the evolution of the universe. There are a few ways the universe might end, but exactly how depends on how the rate of cosmic expansion changes in the future. If gravity overpowers expansion, the cosmos will collapse in a Big Crunch .
Detailed explanation-2: -If the density of the universe is greater than the critical density, then gravity will eventually win and the universe will collapse back on itself, the so called Big Crunch, like the graph’s orange curve.
