Answer 1

The idea that describes the Big Crunch is: After the universe reaches its expansion limit, gravity will pull it all back together.

The Big Crunch theory suggests that if the density of the universe is high enough, the expansion of the universe may eventually reverse, leading all matter to collapse back into a singular point, much like the concept of the Big Bang but in reverse.
