生命对天体物理事件的恢复力
The Resilience of Life to Astrophysical Events
摘要：
文献中对天体物理事件对人类和陆地生活的影响给予了很大的关注。然而，很少有人讨论生命本身的弹性。在这里，我们探索的是一些事件的统计数据，这些事件完全消灭了一个类地行星，其行星半径在$0.5-1.5 R_{Earth}$范围内，温度在$\sim 300 \; \text{K}$范围内，消灭了所有形式的生命。我们认为，相对可能性完整的全球消毒事件从三个天体物理学来源-超新星，伽马射线暴，大的小行星撞击，并通过恒星。为了评估这种可能性，我们考虑了什么样的灾难性事件可能导致地球海洋中所有水的沸腾，不仅是人类生命，而且是极端微生物的灭绝。令人惊讶的是，我们发现，虽然人类的生命是有点脆弱的附近事件，弹性的Ecdysozoa如\emph{Milnesium tardigradum}使全球绝育一个不太可能的事件。
英文摘要：
Much attention has been given in the literature to the effects of astrophysical events on human and land-based life. However, little has been discussed on the resilience of life itself. Here we instead explore the statistics of events that completely sterilise an Earth-like planet with planet radii in the range $0.5-1.5 R_{Earth}$ and temperatures of $\sim 300 \; \text{K}$, eradicating all forms of life. We consider the relative likelihood of complete global sterilisation events from three astrophysical sources -- supernovae, gamma-ray bursts, large asteroid impacts, and passing-by stars. To assess such probabilities we consider what cataclysmic event could lead to the annihilation of not just human life, but also extremophiles, through the boiling of all water in Earth's oceans. Surprisingly we find that although human life is somewhat fragile to nearby events, the resilience of Ecdysozoa such as \emph{Milnesium tardigradum} renders global sterilisation an unlikely event.
