以色列定理:大自然试图告诉我们什么?
The Israel Theorem: What is Nature Trying to Tell Us?
摘要:
我们探讨了可能的物理后果来自这样一个事实,即唯一的静态和渐近平坦的真空时空拥有一个规则的地平线是史瓦西解决方案(以色列定理)。如果从史瓦西度规的小偏差是通过爱因斯坦方程的精确解来描述的(这是应该的),那么对于非常紧凑的配置,在辐射多极矩被辐射的时间尺度上,应该发生重要的物理现象,正如一些结果所示,不同的解决方案属于静态轴对称解的Weyl类爱因斯坦方程。
英文摘要:
We explore the possible physical consequences derived from the fact that the only static and asymptotically-flat vacuum space-time possessing a regular horizon is the Schwarzschild solution (Israel theorem). If small deviations from the Schwarzschild metric are described by means of exact solutions to Einstein equations (as it should be), then for very compact configurations, at the time scale at which radiatable multipole moments are radiated away, important physical phenomena should occur, as illustrated by some results on different solutions beloging to the Weyl class of static axially--symmetric solutions to the Einstein equations.
