The prevalent view that evaporating black holes should simply be smaller black holes has been challenged by the firewall paradox. In particular, this paradox suggests that something different occurs once a black hole has evaporated to one-half its original surface area. Here, we derive variations of the firewall paradox by tracking the thermodynamic entropy within a black hole across its entire lifetime and extend it even to anti-de Sitter space-times. Our approach sweeps away many unnecessary assumptions, allowing us to demonstrate a paradox exists even its initial onset (when conventional assumptions render earlier analyses invalid). The most natural resolution may be to accept firewalls as a real phenomenon. Further, the vast entropy accumulated implies a that goes 'all the way down' in contrast with earlier work describing only a structure at the horizon.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'.
蒸发黑洞应只是较小黑洞的普遍观点受到了防火墙悖论的挑战。特别是，这个悖论表明，一旦黑洞蒸发到其原始表面积的一半，就会发生不同的情况。在这里，我们通过跟踪黑洞在其整个生命周期内的热力学熵来推导防火墙悖论的变体，甚至将其扩展到反德西特时空。我们的方法摒弃了许多不必要的假设，使我们能够证明即使在其初始阶段（当传统假设使早期分析无效时）也存在悖论。最自然的解决方案可能是接受防火墙是一种真实现象。此外，积累的巨大熵意味着与早期仅描述视界处结构的工作相比，存在一种“一直向下”的结构。本文是讨论会议议题“量子力学基础及其对当代社会的影响”的一部分。
