在$r=2M$上霍金蒸发与经典事件视界不一致

Hawking Evaporation is Inconsistent with a Classical Event Horizon at $r=2M$

Borun D. Chowdhury, Lawrence M. Krauss

摘要:

一个简单的经典考虑黑洞的形成和蒸发时间只集中在框架的观察者在无穷远表明,一个下落截止外的事件视界的黑洞必须施加为了形成时间的黑洞事件视界不超过其蒸发时间。我们探讨这个悖论定量和检查可能的截止尺度和普朗克尺度的关系。我们的分析提出了几种不同的可能性,其中没有一种可以经典地解决,所有这些都需要与甚至大黑洞和宏观事件视界相关的新物理学:(1)事件视界永远不会形成,例如由于坍缩期间的辐射(解决信息丢失问题),(2)量子效应可能会影响事件视界附近的时空,其方式改变了陷进以及黑洞蒸发本身。

英文摘要:

A simple classical consideration of black hole formation and evaporation times focusing solely on the frame of an observer at infinity demonstrates that an infall cutoff outside the event horizon of a black hole must be imposed in order for the formation time of a black hole event horizon to not exceed its evaporation time. We explore this paradox quantitatively and examine possible cutoff scales and their relation to the Planck scale. Our analysis suggests several different possibilities, none of which can be resolved classically and all of which require new physics associated with even large black holes and macroscopic event horizons:(1) an event horizon never forms, for example due to radiation during collapse (resolving the information loss problem), (2) quantum effects may affect space-time near an event horizon in ways which alter infall as well as black hole evaporation itself.
