在二维弦理论中，探测器D 0-膜由于其度规耦合和玻色子耦合之间的抵消而看不到黑洞奇点。类似的机制可能在大D维的史瓦西黑洞中起作用，只要考虑一个合适的包裹膜。从渐近观察者看来，包裹的膜看起来消失了，而类时轨迹在奇点之外的延续表明，它将作为一个从奇点伸展出来的瞬时类空弦重新出现。零轨迹可以扩展到奇点之外的零轨迹。不仅有效粒子，而且来自被包裹的膜的有效弦也可以表现出相同的特征。
In two-dimensional string theory, a probe D0-brane does not see the black hole singularity due to a cancellation between its metric coupling and the dilaton coupling. A similar mechanism may work in the Schwarzschild black hole in large D dimensions by considering a suitable wrapped membrane. From the asymptotic observer, the wrapped membrane looks disappearing into nothing while the continuation of the time-like trajectory beyond the singularity suggests that it would reappear as an instantaneous space-like string stretching from the singularity. A null trajectory can be extended to a null trajectory beyond the singularity. Not only the effective particle but an effective string from the wrapped membrane can exhibit the same feature.
