大质量黑洞的蒸发可以通过在一组适当选择的光滑类空间超曲面上定义的低能有效理论来描述其整个生命周期的大部分。关于信息丢失的传统论点基于这样的假设：有效理论是局域量子场论。我们提供的证据表明这个假设在弦理论的背景下是失败的。光锋弦理论中的算符换向器，对应于事件视界两侧的某些低能量观察者，即使这些观察者在空间上相距宏观距离，也仍然很大。这表明黑洞内部的自由度不应被视为独立于事件视界之外的自由度。这些非局域效应仅在极端运动环境下才显着，例如在黑洞的高红移几何结构中。对应于闵可夫斯基空间中普通低能观察者的类空间分离算子的交换子在弦理论中受到强烈抑制。 \textcopyright{} 1995 美国物理学会。
The evaporation of a large mass black hole can be described throughout most of its lifetime by a low-energy effective theory defined on a suitably chosen set of smooth spacelike hypersurfaces. The conventional argument for information loss rests on the assumption that the effective theory is a local quantum field theory. We present evidence that this assumption fails in the context of string theory. The commutator of operators in light-front string theory, corresponding to certain low-energy observers on opposite sides of the event horizon, remains large even when these observers are spacelike separated by a macroscopic distance. This suggests that degrees of freedom inside a black hole should not be viewed as independent from those outside the event horizon. These nonlocal effects are only significant under extreme kinematic circumstances, such as in the high-redshift geometry of a black hole. Commutators of spacelike separated operators corresponding to ordinary low-energy observers in Minkowski space are strongly suppressed in string theory. \textcopyright{} 1995 The American Physical Society.
