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.
