The idea that best describes the big crunch is:

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

The big crunch theory posits that the universe, having expanded to a certain point, will eventually stop expanding and start contracting, ultimately collapsing back into a singular state. The other options discuss related concepts but do not specifically describe the big crunch.
