The Big Bounce is a theory that says our universe didn’t start from a singular Big Bang, but instead came from the collapse of a previous universe that "bounced" back into expansion.
Theory[]
- A universe collapses due to gravity (Big Crunch).
- Instead of a singularity (infinite density), quantum gravity effects stop the collapse.
- The universe rebounds (bounces) and expands again, creating endless cycles of contraction and expansion.
Attractiveness of this theory[]
- Avoids the infinite singularity problem
- Fits with quantum gravity theories like Loop Quantum Gravity.
- Suggests a cyclic universe instead of a one-time creation.
- Might explain cosmic inflation and the structure of the universe.
