标题： Naked Black Holes

摘要： 研究表明，对于一些大质量静态黑洞，在事件视界附近所有曲率不变量都很小，但任何掉入其中的物体在视界外会经历巨大的潮汐力。 这些黑洞带有电荷且接近极端状态，并存在于包括弦理论在内的广泛理论类别中。 讨论了其对宇宙监督假设和黑洞信息悖论的影响。 显示英文摘要

摘要： It is shown that there are large static black holes for which all curvature invariants are small near the event horizon, yet any object which falls in experiences enormous tidal forces outside the horizon. These black holes are charged and near extremality, and exist in a wide class of theories including string theory. The implications for cosmic censorship and the black hole information puzzle are discussed.
