摘要:

研究了曲率发散对测地线完备的黑洞时空中物理观测者的影响。这个时空是广义相对论的某些扩展与麦克斯韦电动力学耦合的精确解,粗略地说,它由两个Reissner-Nordström(或Schwarzschild或Minkowski)几何组成,由中心附近的球形虫洞连接。我们发现,尽管存在无限的潮汐力,因果联系从来没有失去的元素组成的观察者。这表明曲率分歧可能不像传统认为的那样是病态的。

英文摘要:

The impact of curvature divergences on physical observers in a black hole space-time which, nonetheless, is geodesically complete is investigated. This space-time is an exact solution of certain extensions of General Relativity coupled to Maxwell's electrodynamics and, roughly speaking, consists on two Reissner-Nordström (or Schwarzschild or Minkowski) geometries connected by a spherical wormhole near the center. We find that, despite the existence of infinite tidal forces, causal contact is never lost among the elements making up the observer. This suggests that curvature divergences may not be as pathological as traditionally thought.
