论文摘要
我们在这里调查由于具有非零速度函数的球形对称尘埃云的重力崩溃而形成的时空奇异性的局部知名度。研究条件，以确保奇异性的全球可见性，因为即将到来的无效的大地测量学离开了物质云的边界，而过去，这些情况以奇异性终止。构建了这种效果的明确示例。我们要求从Tipler的意义上讲，这必须是强大的曲率奇异性，以确保所考虑的情况的物理意义。这可能是对弱宇宙审查假设的反例。
We investigate here the local versus global visibility of a space-time singularity formed due to the gravitational collapse of a spherically symmetric dust cloud having a non-zero velocity function. The conditions are investigated that ensure the global visibility of the singularity, in the sense that the outgoing null geodesics leave the boundary of the matter cloud in the future, whereas, in the past, these terminate at the singularity. Explicit examples of this effect are constructed. We require that this must be a strong curvature singularity in the sense of Tipler, to ensure the physical significance of the scenario considered. This may act as a counterexample to the weak cosmic censorship hypothesis.
