We consider three fundamental issues in quantum gravity: (a) the black hole information paradox (b) the unboundedness of entropy that can be stored inside a black hole horizon (c) the relation between the black hole horizon and the cosmological horizon. With help from the small corrections theorem, we convert each of these issues into a sharp conflict. We then argue that all three conflicts can be resolved by the following hypothesis: the vacuum wave functional of quantum gravity contains a “vecro” component made of virtual fluctuations of configurations of the same type that arise in the fuzzball structure of black hole microstates. Further, if we assume that causality holds to leading order in gently curved spacetime, then we must have such a vecro component in order to resolve the above conflicts. The term vecro stands for “Virtual Extended Compression-Resistant Object”, and characterizes the nature of the vacuum fluctuations that resolve the puzzles. It is interesting that puzzle (c) may relate the role of quantum gravity in black holes to observations in the sky.

维克罗假说

我们考虑量子引力的三个基本问题：（a）黑洞信息悖论（b）可以存储在黑洞视界内的熵的无限性（c）黑洞视界和宇宙视界之间的关系。在小修正定理的帮助下，我们将这些问题中的每一个都转化为尖锐的冲突。然后，我们认为所有三个冲突都可以通过以下假设来解决：量子引力的真空波泛函包含一个“vecro”分量，该分量由黑洞微状态的绒毛球结构中出现的相同类型配置的虚拟波动组成。此外，如果我们假设因果关系在平缓弯曲的时空中保持领先顺序，那么我们必须有这样一个 vecro 组件才能解决上述冲突。vecro 一词代表“虚拟扩展抗压物体”，它描述了解决难题的真空波动的性质。有趣的是，谜题 (c) 可能将黑洞中量子引力的作用与天空中的观测联系起来。
