AI总结:

研究通过扩展的正则施瓦茨希尔德度规探讨非奇异配置引力坍缩是否能连续形成施瓦茨希尔德黑洞,发现度规函数在原点出现不连续,暗示时空光滑性破裂,需非连续框架描述奇点形成。

摘要:

我们考察施瓦茨希尔德黑洞是否能作为非奇异配置引力坍缩的连续终态。通过时间依赖的正则施瓦茨希尔德度规扩展,追踪坍缩过程中几何的演变,发现该过程无法保持连续。度规函数在原点发展出不连续性,标志着时空光滑性的破裂,即所谓的``米克罗斯基破裂''。在施瓦茨希尔德点源形成于r=0之前,曲率奇点出现且因果 horizon消失。这些结果强烈表明,时空可能无法平滑地趋向施瓦茨希尔德几何。相反,施瓦茨希尔德黑洞的形成似乎涉及时空结构的离散变化,提示需要非连续、可能量子化的框架来描述引力奇点的出现或正则化。

英文摘要:

We examine whether the Schwarzschild black hole can emerge as the continuous end state of gravitational collapse from a non-singular configuration. Employing a time dependent extension of the regular Schwarzschild metric, we track the evolution of the geometry during collapse and find that the process cannot remain continuous. The metric function develops a discontinuity at the origin, marking a breakdown of spacetime smoothness, an effect identified as ``Minkowski breaking.'' Before the Schwarzschild point source can form at $r=0$, curvature singularities appear and the Cauchy horizon disappears. These results strongly suggest that spacetime may not evolve smoothly toward the Schwarzschild geometry. Instead, the formation of a Schwarzschild black hole appears to entail a discrete change in the structure of spacetime, pointing to the need for a noncontinuous, possibly quantized, framework to describe the emergence or regularization of gravitational singularities.
