论文摘要
本文考虑了从蒸发的黑洞到白洞的非单明性过渡的多种“准古典”模型，而白洞的演变比纸张I中所考虑的。折叠外壳外的几何形状的量子进化是通过平稳地覆盖的，该孔从球形的范围中平稳地覆盖的旋转架，并在白色的范围内进行了平稳进化，并在白色的范围内进行了覆盖的范围，该孔在白色的范围内均属于黑色孔。圆周半径具有最小的普朗克尺度值的间距性超曲面。与其专注于有效度量的特定模型和相应的有效应力能量张量，我认为这种过渡的一般特性和黑洞的结束是从假设平滑几何形状之后的。探索了探索白洞演变的替代场景，该场景避免了从纸I场景的白洞长期发射负能量。如果可以牢固地确定通过环量子重力提出的这种过渡，则必须放弃对黑洞细粒熵的常规全息解释。这也将是对广义第二定律和量子奇异定理的反示例。
This paper considers a wider range of "quasi-classical" models for the non-singular transition from an evaporating black hole to a white hole and the evolution of the white hole than were considered in Paper I. The quantum evolution of the geometry outside a collapsing shell is described by a smoothly evolving spherically symmetric effective metric, with a transition from trapped surfaces in the black hole to anti-trapped surfaces in the white hole at a spacelike hypersurface on which the circumferential radius has a minimum Planck-scale value. Rather than focusing on a specific model for the effective metric and the corresponding effective stress-energy tensor, I consider the general properties of such a transition and the end of the black hole following from the assumption of a smooth geometry. Alternative scenarios for the evolution of the white hole, which avoid the prolonged emission of negative energy from the white hole of the Paper I scenario, are explored. If such a transition, suggested by Loop Quantum Gravity, can be firmly established, the conventional holographic interpretation of the fine-grained entropy of a black hole must be abandoned. It would also be a counter-example to the generalized second law and quantum singularity theorems.
