Question

1. one theory about how the universe might end is called the big crunch.it suggests that the expansion of the universe will slow down becausethe density is high enough for gravity to overcome the expansion. oncethe expansion stops, the universe will start to collapse again, until all ofthe mass has come together. which theory would support the idea of thebig crunch?a big bang theoryb open universe theoryc closed universe theoryd flat universe theory

Explanation:

The closed universe theory proposes that the universe has enough mass (high density) for gravity to eventually halt its expansion and cause a collapse, which directly aligns with the big crunch scenario. The big bang theory describes the universe's origin, not its collapse. The open universe theory states the universe will expand forever, and the flat universe theory says expansion will slow but never collapse.

Answer:

C closed universe theory
