摘要
使用同步坐标,沉浸在德西特时空中的史瓦西黑洞的创生可以被视为一族类时测地线的相干创生.先前假设的圆锥奇性在约束瞬子的视界中并不存在.相反地,不可避免的无规性在量子跃迁表面的其他地方表现为不消失的第二基本式.相同的论证可以适用于带电、拓扑或更高维的黑洞.
Abstract
Using the synchronous coordinates,the creation of a Schwarzschild black hole immersed in a de Sitter space-time can be viewed as a coherent creation of a collection of timelike geodesics.The previously supposed conical singular-ities do not exist at the horizons of the constrained instanton.Instead,the unavoidable irregularity is presented as a non-vanishing second fundamental form elsewhere at the quantum transition 3-surface.The same arguments can be applied to charged,topological,or higher dimensional black hole cases.
