论文摘要
以前，我们开发了一个迟到的近似方案，以研究黑洞的内部几何形状。在本文中，我们通过数值相对论模拟测试该方案。特别是，我们介绍了带电的球形对称的两侧黑色孔的内部几何形状的数值相对性模拟，其间距为$ r = 0 $。我们的数字与晚期近似非常吻合。我们还证明，接近$ r = 0 $的几何形状是标量的Kasner几何形状并计算相关的Kasner指数。
Previously, we developed a late time approximation scheme to study the interior geometry of black holes. In the present paper we test this scheme with numerical relativity simulations. In particular, we present numerical relativity simulations of the interior geometry of charged spherically symmetric two-sided black holes with a spacelike singularity at $r = 0$. Our numerics are in excellent agreement with the late time approximation. We also demonstrate that the geometry near $r = 0$ is a scalarized Kasner geometry and compute the associated Kasner exponents.
