论文摘要
我们从一个近乎超级，静态充电的黑洞（带有质量$ m $和充电$ q \ lyssim m $）中研究了一个大量（$ m_w $）未充电的标量数据包的隧道概率。我们表明，确实有一个净概率是从黑洞中大规模的未充电粒子隧道，因此最终状态（具有新的质量$ m'\ equiv m-m_w <q $）确实违反了宇宙审查的猜想。然而，这种黑洞排放的典型时间（即从周围的环境中吸收电荷$ -q $）比隧道时间小得多；因此，在实践中从未实现违规行为。即使对于完全孤立的黑洞（如果存在），地平线附近的标准时间扩张也将典型的违规时间尺度延伸到无法观察的值。
We study the tunneling probability of a massive ($m_w$) uncharged scalar packet out from a near-extremal, static charged black hole (with mass $M$ and charge $Q\lesssim M$). We show that there is indeed a net probability that a massive uncharged particle tunnels out from the black hole so that the final state (with new mass $M'\equiv M-m_w < Q$) does violate the cosmic censorship conjecture. Nevertheless, the typical time for such a black hole to discharge (i.e, to absorb charge $-Q$ from its surroundings and then become neutral) is much smaller than the tunneling time; therefore, the violation is never attained in practice. Even for a completely isolated black hole (should it exist), the standard time dilation near the horizon stretches the typical violation time scale to unobservable values.
