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.黑洞信息悖论是我们理解量子力学与广义相对论时所面临的根本性挑战。本文提出了一种基于时空因果结构与热力学结构的全新解决方案：三世界模型（Three Worlds Model）。在该模型中，黑洞会催生三个因果独立的区域——世界I（外部宇宙）、世界II（黑洞内部）以及世界III（一个全新的膨胀宇宙）。我们证明，该框架通过基于视界的信息存储方式，在世界I中保留了量子幺正性，同时允许世界II中发生信息擦除，进而使得世界III从世界II的零熵态中诞生。该模型无需修改量子力学或广义相对论即可解决该悖论，并给出了具体的观测预言。
