分析了宇宙微波背景辐射的无限蓝移光子与落向Reissner-Nordstr{umlt o}m黑洞内视界的物理物体的相互作用。为了评估这种相互作用，我们考虑了微扰展开中的QED效应，直到二阶。然后我们将QED效应外推到截止，这是我们在普朗克水平上引入的。(我们的结果对截止能量不敏感。)我们发现，入射的观测者所吸收的能量是有限的，对于典型的参数，不会导致灾难性的加热。然而，这种相互作用对人类或其他类似大小的生物来说几乎肯定是致命的。另一方面，我们发现较小的物体可能会在相互作用中幸存下来。我们的结果并不支持将柯西视界视为时空边界的观点。{版权所有}{ITAL 1997}{ITAL The American Physitive Society}
The interaction of the unboundedly blueshifted photons of the cosmic microwave background radiation with a physical object falling towards the inner horizon of a Reissner-Nordstr{umlt o}m black hole is analyzed. To evaluate this interaction we consider the QED effects up to the second order in the perturbation expansion. We then extrapolate the QED effects up to a cutoff, which we introduce at the Planckian level. (Our results are not sensitive to the cutoff energy.) We find that the energy absorbed by an infalling observer is finite, and for typical parameters would not lead to a catastrophic heating. However, this interaction would almost certainly be fatal for a human being, or other living organisms of similar size. On the other hand, we find that smaller objects may survive the interaction. Our results do not provide support for the idea that the Cauchy horizon is to be regarded as the boundary of spacetime. {copyright} {ital 1997} {ital The American Physical Society}
