The big bang actually never occurred, and the universe must have a different origin.

Answer 1

The ideas that describe the big crunch are:

1. After the universe reaches its expansion limit, gravity will pull it all back together.
2. The universe goes through infinite cycles of expansion and contraction.

The big crunch theory suggests that after the universe expands to a certain point, gravitational forces will eventually cause it to reverse and contract back to a singularity, possibly leading to another big bang and a new cycle of expansion.
