AI 中文总结
本文反驳黑洞信息悖论基于非全局双曲性失效的观点，提出预测友好性和回溯预测友好性概念，并论证去理想化蒸发模型可满足二者，从而消解该悖论。
AI 中文摘要
Manchak和Weatherall（2018）将黑洞信息悖论表述为黑洞蒸发时空中可预测性的失效，并通过非全局双曲性进行诊断。我提出了一种解决该悖论的策略。我认为，黑洞蒸发中可预测性的失效并不能很好地通过非全局双曲性来诊断。随后，我考虑了全局双曲性的两种弱化形式：预测友好性和回溯预测友好性，这两种性质的失效可能构成新的悖论基础。然而，去理想化的黑洞蒸发模型可以是预测友好且回溯预测友好的。因此，信息悖论既不能基于全局双曲性的失效，也不能基于回溯预测不友好性或预测不友好性。
英文摘要
Manchak and Weatherall (2018) formulate the black hole information paradox as a failure of predictability in black hole evaporation spacetimes, diagnosed by non-global hyperbolicity. I offer a strategy for resolving this paradox. I argue that failures of predictability in black hole evaporation are not well diagnosed by non-global hyperbolicity. I then consider two weakenings of global hyperbolicity: prediction and retrodiction friendliness, the failure of which could ground a new paradox. However, deidealized black hole evaporation models can be prediction and retrodiction friendly. Therefore, the information paradox cannot be based upon failures of global hyperbolicity, nor either retrodiction or prediction unfriendliness.
