我们构造了一个新的卡片图，它精确地画出了外尔时空，并表示了它们的整体时空结构、奇点、视界和零无穷大。作为例子，我们系统地讨论了各种解决方案，包括黑洞以及最近和新的时间依赖的重力解决方案属于S-膜类的属性。新的含时Weyl解包括S-双洞宇宙、无限阵列和复杂多棒解。这些新的解决方案的有趣的功能之一是，他们有近地平线标度限制，并描述不稳定的对象的衰变。jones@physics.harvard.eduhllywd2@feynman.harvard.edu
We construct a new card diagram which accurately draws Weyl spacetimes and represents their global spacetime structure, singularities, horizons and null infinity. As examples we systematically discuss properties of a variety of solutions including black holes as well as recent and new time-dependent gravity solutions which fall under the S-brane class. The new time-dependent Weyl solutions include S-dihole universes, infinite arrays and complexified multi-rod solutions. Among the interesting features of these new solutions is that they have near horizon scaling limits and describe the decay of unstable objects. jones@physics.harvard.edu hllywd2@feynman.harvard.edu
