论文摘要
我们研究了$ d = 6 $和7个时空尺寸的增强旋转黑洞的碰撞，具有非零影响参数。我们发现存在一组开放的初始条件，使得碰撞的中间状态是一个黑洞，具有哑铃状的地平线，对局部的Gregory-laflampe型不稳定不稳定。我们能够提供令人信服的数值证据，即这种不稳定性的演变导致在有限的渐近时间中从地平线上捏合，从而形成了裸露的奇异性，就像在类似的不稳定的黑洞中一样。由于最初状态的黑洞是稳定的，因此这是第一个真正的通用证据，证明违反了较高的渐近渐近平坦的较高尺寸较高的估计猜想。
We study collisions of boosted rotating black holes in $D=6$ and 7 spacetime dimensions with a non-zero impact parameter. We find that there exists an open set of initial conditions such that the intermediate state of the collision is a black hole with a dumbbell-like horizon which is unstable to a local Gregory-Laflamme-type instability. We are able to provide convincing numerical evidence that the evolution of such an instability leads to a pinch off of the horizon in finite asymptotic time thus forming a naked singularity, as in similar unstable black holes. Since the black holes in the initial state are stable, this is the first genuinely generic evidence for the violation of the Weak Cosmic Censorship Conjecture in higher dimensional asymptotically flat spacetimes.
