黑太阳下的生活

Life under a black sun

Tomáš Opatrný, Lukáš Richterek, Pavel Bakala

摘要:

生命依赖于低熵能量的收入和高熵能量的处理。在地球上,低熵能量由太阳辐射提供,而高熵能量则以红外辐射的形式发射到寒冷的太空中。在这里,我们把情况反过来,假设宇宙背景辐射是一颗行星绕着一个黑洞运行的低熵能量源,而高熵能量则被注入黑洞。我们估计的权力,可以产生的热力学过程中这样的行星,特别是在行星轨道上的快速旋转克尔黑洞的兴趣在科幻电影{ \em星际}。我们还简要讨论了一个从外部吸收宇宙背景辐射并将废能倾倒到内部黑洞的反戴森球。

英文摘要:

Life is dependent on the income of energy with low entropy and the disposal of energy with high entropy. On Earth, the low-entropy energy is provided by solar radiation and the high-entropy energy is disposed as infrared radiation emitted into the cold space. Here we turn the situation around and assume cosmic background radiation as the low-entropy source of energy for a planet orbiting a black hole into which the high-entropy energy is disposed. We estimate the power that can be produced by thermodynamic processes on such a planet, with a particular interest in planets orbiting a fast rotating Kerr black hole as in the science fiction movie {\em Interstellar}. We also briefly discuss a reverse Dyson sphere absorbing cosmic background radiation from the outside and dumping waste energy to a black hole inside.
