费米粒子的可持续性解决方案

The Sustainability Solution to the Fermi Paradox

Jacob D. Haqq-Misra, Seth D. Baum

摘要:

目前还没有观测表明一个技术先进的地外文明(ETI)已经在银河系中传播。然而,在关于银河文明形成和扩张的普遍假设下,这种观测的缺失是极不可能的。这种不可能性是费米粒子的核心。费米悖论让一些人得出结论,人类是这个星系中唯一的先进文明,要么是因为文明的形成非常罕见,要么是因为智能文明不可避免地会自我毁灭。在本文中,我们认为,这一结论是不成熟的,通过引入“可持续发展的解决方案”的费米帕萨特,质疑帕萨特的假设更快(例如指数)的文明增长。从地球上人类文明的可持续性的见解,我们提出,更快的增长可能是不可持续的银河系规模。如果是这样的话,那么可能存在ETI,它们没有在整个星系中膨胀,或者已经膨胀了,但已经坍缩了。这些可能性对搜寻ETI和人类文明管理都有影响。

英文摘要:

No present observations suggest a technologically advanced extraterrestrial intelligence (ETI) has spread through the galaxy. However, under commonplace assumptions about galactic civilization formation and expansion, this absence of observation is highly unlikely. This improbability is the heart of the Fermi Paradox. The Fermi Paradox leads some to conclude that humans have the only advanced civilization in this galaxy, either because civilization formation is very rare or because intelligent civilizations inevitably destroy themselves. In this paper, we argue that this conclusion is premature by introducing the "Sustainability Solution" to the Fermi Paradox, which questions the Paradox's assumption of faster (e.g. exponential) civilization growth. Drawing on insights from the sustainability of human civilization on Earth, we propose that faster-growth may not be sustainable on the galactic scale. If this is the case, then there may exist ETI that have not expanded throughout the galaxy or have done so but collapsed. These possibilities have implications for both searches for ETI and for human civilization management.
