摘要

以前已经证明，阿贝尔电磁规范变换可以在时空中创造一个被零曲面包围的区域，使得在该曲面内时空发生类时-类空反射。因此，在零面内部，类时间间隔会变成类空间间隔，反之亦然。我们将利用这一性质来证明这样一个封闭区域将能够在四维爱因斯坦-麦克斯韦或麦克斯韦-闵可夫斯基时空中经历比光速更快的运动。

Spacelike Motion inside a Closed Null Surface Generated by Abelian Electromagnetic Gauge Transformations

It has been proven previously that Abelian electromagnetic gauge transformations can create a region in spacetime surrounded by a null surface such that inside the surface spacetime undergoes a timelike-spacelike reflection. Therefore, timelike intervals will turn into spacelike intervals inside the null surface and vice versa. We will use this property in order to prove that such a closed region will be able to undergo faster than the speed of light motion in a four-dimensional Einstein–Maxwell or Maxwell–Minkowski spacetimes.
