黑洞余迹与信息损失粒子

Black Hole Remnants and the Information Loss Paradox

Pisin Chen, Yen Chin Ong, Dong-han Yeom

摘要:

在发现霍金辐射40年后,它的确切性质仍然难以捉摸。如果霍金辐射不能从不断缩小的黑洞中携带出任何信息,那么一旦黑洞完全蒸发,幺正性似乎就被破坏了。另一方面,试图恢复信息通过量子纠缠导致防火墙的争议。在混乱中,黑洞蒸发停止的可能性仍然不受欢迎,并且由于这种物体的一些“不希望的性质”而经常被驳回。然而,正如在任何科学辩论中一样,任何提案的利弊都必须仔细审查。我们填补了文献的空白,提供了一个及时的审查各种类型的黑洞遗迹,并提供了一些新的思考,黑洞遗迹面临的挑战的背景下,信息丢失悖论及其最新的化身,即防火墙的争议。我们还强调了理解曲率奇异性作用的重要性,毕竟存在着即使用量子引力也无法治愈的奇异性。在这种情况下,一个黑洞的残余物很方便地充当了宇宙审查员。我们的结论是,残留物仍然是一个可能的霍金蒸发的最终状态,如果它包含大的内部几何,可能有助于改善信息丢失悖论和防火墙的争议。我们希望,这将提高社会的一些兴趣,以更严格地调查残余,但也更彻底。

英文摘要:

Forty years after the discovery of Hawking radiation, its exact nature remains elusive. If Hawking radiation does not carry any information out from the ever shrinking black hole, it seems that unitarity is violated once the black hole completely evaporates. On the other hand, attempts to recover information via quantum entanglement lead to the firewall controversy. Amid the confusions, the possibility that black hole evaporation stops with a "remnant" has remained unpopular and is often dismissed due to some "undesired properties" of such an object. Nevertheless, as in any scientific debate, the pros and cons of any proposal must be carefully scrutinized. We fill in the void of the literature by providing a timely review of various types of black hole remnants, and provide some new thoughts regarding the challenges that black hole remnants face in the context of the information loss paradox and its latest incarnation, namely the firewall controversy. The importance of understanding the role of curvature singularity is also emphasized, after all there remains a possibility that the singularity cannot be cured even by quantum gravity. In this context a black hole remnant conveniently serves as a cosmic censor. We conclude that a remnant remains a possible end state of Hawking evaporation, and if it contains large interior geometry, may help to ameliorate the information loss paradox and the firewall controversy. We hope that this will raise some interests in the community to investigate remnants more critically but also more thoroughly.
