observations indicate that the universe has a circular geometry. a closed geometry. an open geometry. a flat geometry. this geometry means that the universe will collapse down to a singularity, then bounce back into expansion of a new universe. expand forever. reach a static, unchanging size in the distant future. collapse into a singularity (a \big crunch\) in the distant future.

observations indicate that the universe has a circular geometry. a closed geometry. an open geometry. a flat geometry. this geometry means that the universe will collapse down to a singularity, then bounce back into expansion of a new universe. expand forever. reach a static, unchanging size in the distant future. collapse into a singularity (a \big crunch\) in the distant future.

Answer

Brief Explanations:

Observations from cosmic microwave - background radiation and large - scale structure surveys strongly suggest that the Universe has a flat geometry. In a flat Universe, the density parameter is equal to 1. A flat Universe will expand forever according to the current understanding of cosmology.

Answer:

First question: a flat geometry. Second question: expand forever.
