>The "Big Crunch" theory is an older concept suggesting the universe's expansion will reverse due to gravity, causing it to collapse back into a single point. This has led to theories of cyclic universes, where a "Big Bounce" follows the Big Crunch, leading to a new Big Bang. While the current standard model predicts eternal expansion, some recent theories and evidence for evolving dark energy propose that a future contraction is a possibility.
