论文摘要
众所周知，对爱因斯坦方程的可穿越的虫洞溶液需要违反无效能量条件的异国物质来源。一个明显的例外是爱因斯坦 - 马克斯韦尔方程的Kerr-Newman-Nut解决方案，它具有地理上完整，可穿越的虫洞时空的所有特性。我们表明，采购的异国情调的物质包括两个反向伸展的无张力的直宇宙弦 - Misner-Dirac Strings-正如预期的那样，它违反了无效的能量条件。虫洞具有巨大的巨人，但没有超级崇拜。简要讨论了该时空中的测量运动，并证明了闭合圆形无循环零用测量学的缺失。
It is well-known that traversable wormhole solutions to the Einstein equations require the existence of an exotic matter source violating the null energy condition. An apparent exception is the overcharged Kerr-Newman-NUT solution of the Einstein-Maxwell equations, which has all the properties of a geodesically complete, traversable wormhole spacetime. We show that the exotic matter sourcing this consists in two counter-rotating tensionless straight cosmic strings -- the Misner-Dirac strings -- which, as expected, violate the null energy condition. The wormhole possesses an ergoregion, but no superradiance. The geodesic motion in this spacetime is briefly discussed, and the absence of closed circular null geodesics is demonstrated.
