Question

Quizplus · Accepted Answer

The low-density universe has a density parameter Ω less than 1, which means that the universe will continue to expand forever. This is known as an open universe. The low-density universe is characterized by a low matter density, which leads to a weak gravitational pull and a lower chance of the universe collapsing in on itself. This means that the expansion of the universe will continue indefinitely.
