The universe goes through infinite cycles of expansion and contraction.

Answer 1

The idea that describes the big crunch is:

**After the universe reaches its expansion limit, gravity will pull it all back together.**

This concept refers to a theoretical scenario in which the universe's expansion eventually reverses, leading to a contraction that could result in the universe collapsing back into a singular state.

While the other statements touch on different concepts related to cosmology, they do not specifically describe the big crunch.
