黑洞内部是什么？--正则量子引力的新视角

WHAT'S INSIDE BLACK HOLES?——NEW PERSPECTIVES ON CANONICAL QUANTUM GRAVITY

我们在最新的一份研究工作中找到了带有分层不均匀特征动态塌缩星内部时空度规的一般形式,结合爱因斯坦场方程,该度规告诉我们构成黑洞的物质很可能在视界内经历着反复的收缩—收缩过头—反向膨胀到极大—再收缩—再过头的呼吸运动。我们同时在广义相对论和正则量子引力的水平上,提供了这种过零点"呼吸"运动可能恰好具有exp(A/l_(pl)~2)种可能本征态的数值证据,此处A为视界面积,从而为史瓦西奇点的消解、黑洞熵的微观解释以及信息丢失疑难的解决提供了一条新思路。本文是对这一技术性研究工作所揭示物理图像的中文版介绍,并添加了跟弦理论、圈量子引力图像的对比以及关于其可证伪性的讨论。

In a recent technical work, we find collapsing stars with layering inhomogeneities. general expressions for the inner geometry of This tells us that matters inside the horizon of black holes could experience periodical motion of contracting and overdoing-anti-directionally expanding to rnaximal--contracting again. At both classical and quantum levels we find evi dences that this zero-crossing motion may happen have exp（A/l} ） possible eigen-ways thus provide a new perspective for the resolution of the Schwarzschild singularity, interpretations for the micro-origin of black hole＇s entropy and the information missing puzzle＇s resolving. This paper is aimed to provide the physic picture explanation to the Chinese audience, we have also added comparisons between our picture following from canonical quantum gravity and those from string theory and loop quantum gravity. We also discuss the dis/verifications of this picture through future observations of gravitational waves produced from the binary black hole＇s merging.
