我们利用两个带电壳的引力场构造了一个静态的轴对称虫洞。对于大的分离，外部倾向于两个带电粒子的Majumdar-Papapetrou时空。虫洞的内部是一个与两个壳层相匹配的Reissner-Nordstr“om黑洞。虫洞是可穿越的，并且连接到相同的渐近性，而不违反能量条件。然而，Majumdar-Papapetrou区域中的每一点都位于封闭的类时曲线上。
We construct a static axisymmetric wormhole from the gravitational field of two charged shells which are kept in equilibrium by their electromagnetic repulsion. For large separations the exterior tends to the Majumdar-Papapetrou spacetime of two charged particles. The interior of the wormhole is a Reissner-Nordstr"om black hole matching to the two shells. The wormhole is traversable and connects to the same asymptotics without violation of energy conditions. However, every point in the Majumdar-Papapetrou region lies on a closed timelike curve.
