论文摘要
弦理论中的微晶几何形状在地平线上用光滑的几何“盖”代替了黑洞地平线。在使用超图技术构建的几何形状中，该上限具有令人惊讶的特性，该特性会引起远离它的信息的观察者的较大潮汐变形。我们发现，这种潮汐效应的这种大距离放大也存在于构造为冒泡溶液的地平线微晶格几何形状中，但可以通过适当排列气泡来驯服以降低某些引力多极矩的强度来驯服。然而，尽管有这种驯服，但这些潮汐效应仍然在与微观结构之间的距离很大的距离处变得很大。该结果表明，观察者不会不会陷入代替黑洞地平线的结构中。
Microstate geometries in string theory replace the black-hole horizon with a smooth geometric "cap" at the horizon scale. In geometries constructed using superstratum technology, this cap has the somewhat surprising property that induces very large tidal deformations on infalling observers that are far away from it. We find that this large-distance amplification of the tidal effects is also present in horizonless microstate geometries constructed as bubbling solutions, but can be tamed by suitably arranging the bubbles to reduce the strength of some of the gravitational multipole moments. However, despite this taming, these tidal effects still become large at a significant distance from the microstructure. This result suggests that an observer will not fall unharmed into the structure replacing the black hole horizon.
