论文摘要

众所周知,宇宙审查制度在某些良好控制的现象中失败,质疑一般相对论的预测能力,并开放了观察普朗克级物理学的可能性。我们建议可以对宇宙审查制度进行修改,以使其精神占上风。从经典上讲,裸质量是零质量的。从物理上讲,这些是普朗克大小的“黑洞”,在几次普朗克时代蒸发。一般相对性仅在及时的微小间隔中失败,然后在米尔顿的进化中迅速重新获得控制,这使我们回到了爱因斯坦方程的预测天堂。如果这种猜想的完善是正确的,那么即使自然确实允许在时空的光滑结构中暴露出崩溃,它也会将它们限制为最小值。

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.
