Cosmic censorship is known to fail in some well-controlled phenomena, calling into question the predictive power of General Relativity and opening up the possibility of observing Planck-scale physics. We propose that the cosmic censorship conjecture can be amended so that its spirit prevails. Naked singularities that, classically, have zero mass are allowed. Physically, these are Planck-sized “black holes”, which evaporate in a few Planck times. General Relativity fails only for a tiny interval in time, to then quickly regain control in a Miltonian evolution that returns us to the predictive paradise of Einstein’s equations. If this refinement of the conjecture is correct, then, even though Nature does allow to expose breakdowns in the smooth fabric of spacetime, it limits them to a mostly harmless minimum.

失去预测性,重新获得预测性:弥尔顿宇宙审查猜想

众所周知,宇宙审查在一些控制良好的现象中会失败,这对广义相对论的预测能力提出了质疑,并开辟了观察普朗克尺度物理学的可能性。我们建议可以修改宇宙审查猜想,使其精神盛行。经典上质量为零的裸奇点是允许的。在物理上,这些是普朗克大小的“黑洞”,在普朗克数次内蒸发。广义相对论只在很小的时间间隔内失败,然后迅速重新控制弥尔顿演化,使我们回到爱因斯坦方程的预测天堂。如果猜想的这种改进是正确的,那么,即使大自然确实允许暴露时空平滑结构中的故障,它也会将它们限制在几乎无害的最低限度。
