根据以前关于磁单极子的工作，如果希格斯场的真空期望值大于一个临界值，即普朗克质量量级，则静态正则解是不存在的。为了了解�>；�cr的单极子的性质，我们用数值方法研究了它们的动力学性质。如果足够大(≫�cr)，则无论耦合常数和初始构型如何，单极子以指数方式膨胀，并且在其周围出现虫洞结构。如果在cr附近，根据耦合常数和初始构型，有三种类型的解：单极子要么如上所述膨胀，要么塌缩成黑洞，要么变成稳定的构型。
According to previous work on magnetic monopoles, static regular solu- tions are nonexistent if the vacuum expectation value of the Higgs fieldis larger than a critical valuecr, which is of the order of the Planck mass. In order to understand the properties of monopoles for � > �cr, we investigate their dynamics numerically. Ifis large enough (≫ �cr), a monopole expands exponentially and a wormhole structure appears around it, regardless of cou- pling constants and initial configuration. Ifis aroundcr, there are three types of solutions, depending on coupling constants and initial configuration: a monopole either expands as stated above, collapses into a black hole, or comes to take a stable configuration.
