Three Worlds: A Causal Resolution to the Black Hole Information Paradox

The black hole information paradox arises from the assumption that quantum information must remain accessible within a single, globally connected spacetime. We propose that this assumption is physically unjustified. Instead, the event horizon acts as an absolute causal boundary that bifurcates reality into three causally disjoint worlds: (I) the external universe, (II) the black hole interior, and (III) a nascent universe born from Planck-scale gravitational collapse. Within this Three-Worlds Theory, unitarity is preserved in each world separately; the thermal character of Hawking radiation reflects causal isolation—not information loss. Crucially, only black holes with spacelike point singularities (e.g., near-Schwarzschild) generate sufficient local stress on the fundamental relational fabric to trigger topological reconfiguration and birth World III. Rotating (Kerr) black holes, with their timelike ring singularities, distribute curvature over a loop and fail to exceed the critical pressure threshold—thus producing only two worlds. The energy transfer to World III manifests as dark energy in World I, predicting a slowly time-varying Hubble parameter. This background-independent, four-dimensional framework resolves the paradox without firewalls, remnants, extra dimensions, or modifications to quantum theory.黑洞信息悖论（black hole information paradox）的提出，源于“量子信息必须始终可在单一全局连通的时空内被获取”这一预设。我们认为该预设在物理上并不成立。与之相反，事件视界 (event horizon) 可作为绝对因果边界，将实在界分叉为三个因果互不连通的世界：(I) 外部宇宙、(II) 黑洞内部，以及(III) 由普朗克尺度引力坍缩诞生的新生宇宙。在这一“三世界理论”框架内，每个世界各自满足幺正性 (unitarity)；霍金辐射 (Hawking radiation) 的热特性，实则反映的是因果隔离，而非信息丢失。尤为关键的是，仅具有类空点奇点 (spacelike point singularities) 的黑洞（例如近似史瓦西 (Schwarzschild) 黑洞），能够在基本关联结构上产生足够强的局域应力，从而触发拓扑重构并诞生第三个世界。而带有类时环形奇点 (timelike ring singularities) 的旋转（克尔 (Kerr)）黑洞，其曲率分布在一个环面上，无法超过临界压强阈值——因此仅会产生两个世界。向第三个世界传递的能量，在外部宇宙中会表现为暗能量 (dark energy)，由此可预言出一个随时间缓慢变化的哈勃参数 (Hubble parameter)。这一背景无关 (background-independent) 的四维框架，无需借助黑洞防火墙、黑洞残骸、额外维度，亦无需修改量子理论，便可解决该悖论。
