费米粒子、自复制探针和星际传输带宽
The Fermi Paradox, Self-Replicating Probes, and the Interstellar Transportation Bandwidth
摘要：
人们普遍认为，相对于星系的年龄，自我复制的空间探测器（SRP）可以非常快地探索星系。一个明显的暗示是，地外文明产生的SRPs应该在数百万年前到达我们的太阳系，而且，来自不断出现的文明供应的新探测器应该不断到达。缺乏对这种探测器的观测是费米粒子经常被引用的一种变体的基础。我们相信，对ETI乐观理论的偏好阻碍了对不相容理论的考虑。值得注意的是，SRPs实际上已经从文献中消失。在本文中，我们认为最常见的反对SRP的论点，并发现这些论点缺乏。推而广之，我们发现最近的银河系探索模型，明确排除SRPs是不公平的障碍，不太可能代表自然的情况。我们还考虑了其他几个试图解释费米粒子的模型，最著名的是渗透理论和两个社会崩溃理论。在前一种情况下，我们发现它强加了不自然的假设，这可能使它不切实际。在后一种情况下，我们提出了一个新的星际运输带宽的理论，质疑社会崩溃理论的有效性。最后，我们提供了我们的想法，如何设计未来的SETI计划，考虑到本文的结论，以最大限度地提高检测的机会。
英文摘要：
It has been widely acknowledged that self-replicating space-probes (SRPs) could explore the galaxy very quickly relative to the age of the galaxy. An obvious implication is that SRPs produced by extraterrestrial civilizations should have arrived in our solar system millions of years ago, and furthermore, that new probes from an ever-arising supply of civilizations ought to be arriving on a constant basis. The lack of observations of such probes underlies a frequently cited variation of the Fermi Paradox. We believe that a predilection for ETI-optimistic theories has deterred consideration of incompatible theories. Notably, SRPs have virtually disappeared from the literature. In this paper, we consider the most common arguments against SRPs and find those arguments lacking. By extension, we find recent models of galactic exploration which explicitly exclude SRPs to be unfairly handicapped and unlikely to represent natural scenarios. We also consider several other models that seek to explain the Fermi Paradox, most notably percolation theory and two societal-collapse theories. In the former case, we find that it imposes unnatural assumptions which likely render it unrealistic. In the latter case, we present a new theory of interstellar transportation bandwidth which calls into question the validity of societal-collapse theories. Finally, we offer our thoughts on how to design future SETI programs which take the conclusions of this paper into account to maximize the chance of detection.
