Near-critical type II gravitational collapse is characterized by the formation of arbitrarily small black holes whose horizon radii are described by the simple scaling law , where γ is the matter-dependent Choptuik critical exponent and is the phase space distance from the exact self-similar critical evolution. We point out that all matter models studied thus far in the physics literature are characterized by the upper bound . We conjecture that this is a generic feature of non-linear gravitational collapse scenarios.

Choptuik临界指数的一个猜想上限
接近临界的II型重力塌陷的特征是形成了任意小的黑洞,其黑洞半径由简单的比例定律描述。 ,其中γ是与物质有关的Choptuik临界指数,而是距精确的自相似临界演化的相空间距离。我们指出,到目前为止,物理学文献中研究的所有物质模型都具有上限。我们推测这是非线性重力坍塌情况的普遍特征。
