低能弦论预言黑洞隐藏着一个新宇宙

Low-Energy String Theory Predicts Black Holes Hide a New Universe

Robert Brandenberger, Lavinia Heisenberg, Jakob Robnik

摘要:

我们提出了一个解决黑洞奇异性的构造,并使各向异性宇宙学从洞的内部出现。该模型依赖于在描述时空几何的有效作用量上增加一个S-膜。这个类空缺陷位于视界内部,外尔曲率达到极限值的表面上。我们研究如何从黑洞外的度量波动演变的宇宙学阶段的开始,未来的S-膜。我们的设置地址i)黑洞奇异性问题,ii)宇宙学奇异性问题和iii)信息丢失悖论,因为传出的霍金辐射纠缠的状态内的黑洞,成为新的宇宙。

英文摘要:

We propose a construction with which to resolve the black hole singularity and enable an anisotropic cosmology to emerge from the inside of the hole. The model relies on the addition of an S-brane to the effective action which describes the geometry of space-time. This space-like defect is located inside of the horizon on a surface where the Weyl curvature reaches a limiting value. We study how metric fluctuations evolve from the outside of the black hole to the beginning of the cosmological phase to the future of the S-brane. Our setup addresses i) the black hole singularity problem, ii) the cosmological singularity problem and iii) the information loss paradox since the outgoing Hawking radiation is entangled with the state inside the black hole which becomes the new universe.
