The Big Bang may not be the beginning of the universe; it could have resulted from a gravitational collapse inside a black hole.
The new model proposes that gravitational collapse does not necessarily lead to a singularity but may instead cause a 'bounce' that begins a new expansion phase.
This bounce model explains phenomena such as cosmic inflation and dark energy without requiring new or unknown physics.
The model predicts observable outcomes, like a slightly curved universe, and aligns with future cosmic missions for verification.
