摘要

我們按照 Wald 的假想實驗對Einstein-Maxwell-dilaton 理論中的宇宙審查進行試驗，透過測試粒子來摧毀黑洞，我們發現在帶有特定能量的粒子可以破壞極端帶電的dilaton 黑洞。然而我們如果考慮了self-force 等反作用力，宇宙審查將不會被違反。最後我們討論了 Hoop 猜想和弱重力猜想之間的關聯，以及使用了廣義的熱力學第二定律來保護宇宙審查制度。

We explore the cosmic censorship in the Einstein-Maxwell-dilaton theory following Wald’s thought experiment to destroy a black hole by throwing in a test particle. We discover that at probe limit the extremal charged dilaton black hole could be destroyed by a test particle with specific energy. Nevertheless the censorship is well protected if backreaction or self-force is included. At the end, we discuss an interesting connection between Hoop Conjecture and Weak Gravity Conjecture.
