The Universe's Rebirth: The Big Bounce
The Big Bounce is a scientific idea that suggests the universe may one day stop expanding and start to contract. This contraction could pull everything in the universe back together, leading to a state where it becomes very small again. Theoretically, after this collapse, the universe might then "bounce" back, expanding anew, which means it could go through an endless cycle of birth, death, and rebirth.
