A New Perspective on the Black Hole Information Paradox: The Three Worlds Model of Cosmic Rebirth

The black hole information paradox is a fundamental challenge to our understanding of quantum mechanics and general relativity. This paper proposes a novel resolution grounded in the causal and thermodynamic structure of spacetime: the Three Worlds Model. In this model, black holes give rise to three causally autonomous regions — World I (the external universe), World II (the black hole interior), and World III (a new expanding universe). We show that this framework preserves quantum unitarity within World I through horizon-based information storage while allowing for information erasure in World II, leading to the birth of World III from the zero-entropy state of World II. This model resolves the paradox without modifying quantum mechanics or general relativity, offering concrete observational predictions.
