黑洞中可能存在超越人类的文明

　　Despite being considered the most destructive force in space and absolutely uninhabitable, the conditions for life exist inside supermassive black holes, a Russian cosmologist has theorised. Vyacheslav Dokuchaev has even suggested that if life did exist inside the SBH, it would have evolved to become the most advanced civilisation in the galaxy.
　　尽管超大质量黑洞被认为最具破坏力并且绝对无法居住，然而俄罗斯的一名宇宙学家理论上认为，黑洞中有生命存在的条件。Vyacheslav Dokuchaev甚至曾暗示说，如果黑洞中真的有生命存在，他们已经进化成银河中最先进的文明。

　　Supermassive black holes are such powerful gravitational forces that they suck in everything around them, including light, and nothing that crosses the black hole's 'event horizon（at the lip of the black hole）' is ever seen again.

　　超大质量黑洞引力非常强大，会将它周围的一切都吸进去，任何穿过黑洞视界（即黑洞的边缘）的东西都将永无再现之日，包括光。

　　But now Dokuchaev, of Moscow's Institute for Nuclear Research of the Russian Academy of Sciences, says existing evidence combined with new research throws up intriguing possibilities for certain types of black holes.

　　但是现在，莫斯科核研究所俄罗斯科学院的Dokuchaev说，现有证据结合最新的研究引出了对特定类型黑洞来说非常有趣的可能性。

　　Inside a charged, rotating black hole there are regions where photons can survive in stable periodic orbits. Dokuchaev specialises in studying those orbits and their dynamics.

　　带电荷的、旋转的黑洞中，光子能够在一些区域内幸存，并且进行稳定的、周期性轨道运行。

　　He speculates, in a paper published in Cornell University's online journal arXiv, that if there are stable orbits for photons, there is no reason why there could not be stable orbits for larger objects, such as planets.

　　Dokuchaev在发表在美国康奈尔大学网络期刊arXiv的一篇论文中推测说，如果光子在黑洞中有稳定轨道，比如行星等大的物体在黑洞中没有稳定轨道是非常没有理由的。

　　The problem is that these stable orbits would only exist once you have crossed the threshold of the event horizon, where time and space flow into one another.

　　问题是，只有曾穿过黑洞视界的临界才会存在稳定轨道，那里时间与空间会流入其他地方。

　　However, beyond the event horizon is another domain, known as the Cauchy horizon, where time and space return to stable states. It is inside the Cauchy horizon that life could exist, Dokuchaev argues in the paper published in arXiv, and the type of life that could exist in those conditions - where they would be subject to massive fluctuating tidal forces - would have evolved beyond ours.

　　然而，黑洞视界的另一边是一片被称作柯西视界的领域，那里的时空会恢复到稳定状态。Dokuchaev在发表在arXiv的论文中主张，柯西视界中有生命存在的可能, 而且在那种条件下存活的生命很可能进化的比人类还好，他们可能受支配与巨大的、波动的潮汐力。

　　Though that is a spine-tingling thought, Dokuchaev's proposition can only ever remain theoretical. Because nothing can ever escape from a black hole due to its enormous gravitational pull, we will never know if it is true.

　　虽然这是一个令人兴奋的想法，可是Dokuchaev的这项议题很可能永远只停留在理论层面。因为任何事物都无法逃离黑洞的巨大引力，我们永远也无法知道Dokuchaev的议题是不是真的。
