Black hole image encoding quantum gravity information

Cong Zhang, Yongge Ma, Jinsong Yang

AI总结:

本文通过Kruskal时空的量子扩展,揭示了伴生黑洞辐射经白洞显现并在本宇宙黑洞阴影区形成额外亮环的机制,为检验量子引力预言的黑洞到白洞转变现象提供了新的实验途径。

摘要:

Kruskal时空的量子扩展表明,在比我们宇宙更早的宇宙中存在一个伴生黑洞。研究表明,来自伴生黑洞的辐射可以进入其视界,穿过深层普朗克区域,并从我们宇宙中的白洞显现出来。这些辐射在我们宇宙中的黑洞图像中嵌入了额外的亮环,其中一些亮环清晰地出现在阴影区域内。因此,我们观测到的黑洞图像编码了量子引力的信息。亮环的位置和宽度被精确预测。对于具有黑洞到白洞转变现象的一大类相当普遍的量子修正时空,超大质量黑洞的预测值是普适的。因此,我们的结果为检验量子引力所预言的这一现象打开了一个新的实验窗口。

英文摘要:

The quantum extension of the Kruskal spacetime indicates the existence of a companion black hole in the universe earlier than ours. It is shown that the radiations from the companion black hole can enter its horizon, pass through the deep Planck region, and show up from the white hole in our universe. These radiations inlay extra bright rings in the image of the black hole in our universe, and some of these rings appear distinctly in the shadow region. Therefore, the image of the black hole observed by us encodes the information of quantum gravity. The positions and widths of the bright rings are predicted precisely. The predictive values for supermassive black holes are universal for a quite general class of quantum-modified spacetimes with the phenomenon of black hole to white hole transition. Thus, our result opens a new experimental window to test this phenomenon predicted by quantum gravity.
