As first discovered by Choptuik, the black hole threshold in the space of initial data for general relativity shows both surprising structure and surprising simplicity. Universality, power-law scaling of the black hole mass, and scale echoing have given rise to the term "critical phenomena". They are explained by the existence of exact solutions which are attractors within the black hole threshold, that is, attractors of codimension one in phase space, and which are typically self-similar. Critical phenomena give a natural route from smooth initial data to arbitrarily large curvatures visible from infinity, and are therefore likely to be relevant for cosmic censorship, quantum gravity, astrophysics, and our general understanding of the dynamics of general relativity.

引力坍塌中的关键现象。

正如Choptuik首次发现的那样,广义相对论的初始数据空间中的黑洞阈值既显示出令人惊讶的结构,也显示出令人惊讶的简单性。普遍性,黑洞质量的幂律定标和标度回波引起了术语“临界现象”。通过精确解的存在来解释它们,这些精确解是黑洞阈值内的吸引子,即相空间中余维一的吸引子,并且通常是自相似的。临界现象为从平滑的初始数据到无限大的任意曲率提供了自然的途径,因此可能与宇宙审查,量子引力,天体物理学以及我们对广义相对论动力学的一般理解有关。
