论文摘要
在回顾了用于表征黑洞边界的现有定义的缺点之后，我们提出了一种新方法来表征其表征。该定义可能可以应用于位于爱因斯坦磁场方程的一般黑洞溶液的边界。使用我们的定义，通常在球形对称的空间中，我们认为一个观察者落入黑洞中遇到了黑洞边界处的无限能量密度，压力和通量。该结果被解释为防止经典黑洞增长的防火墙。但是，不能排除通过量子机械隧穿的黑洞生长的可能性。
After reviewing the shortcomings of existing definitions used to characterize the boundary of a black hole, we present a new method for its characterization. This definition could potentially be applied to locate the boundary of general black hole solutions of the Einstein field equations. Using our definition in general spherically symmetric spacetimes, we argue that an observer falling into a black hole encounters an infinite energy density, pressure, and flux at the black hole boundary. This result is interpreted as a firewall that prevents the growth of classical black holes. However, the possibility of black hole growth via quantum mechanical tunneling cannot be ruled out.
