Quizplus · Accepted Answer

The value of Ωmass (the ratio of the mass density of the universe to the critical density) would determine the evolution and fate of the universe if there were no dark energy. A value of Ωmass greater than 1 would lead to a closed universe, where the expansion of the universe stops and begins to contract. A value of Ωmass less than 1 would lead to an open universe, where the expansion continues indefinitely. A value of Ωmass equal to 1 would lead to a flat universe, where the expansion continues indefinitely at a decreasing rate.
