参考答案:
The universe would eventually collapse in on itself if it had a positive curvature. This would mean that there is so much mass in the universe that the gravitational attraction would pull all of the mass of the universe back into a “big crunch.” In this situation, the average density of the universe would be greater than the critical density.
