The idea that describes the big crunch is:
**3. After the universe reaches its expansion limit, gravity will pull it all back together.**
The big crunch is a theoretical scenario in which the expansion of the universe eventually slows down and reverses, leading to a collapse back into a singular state due to gravitational attraction.
