Abstract

Abstract A Von Neumann probe is a self-reproducing intelligent device with interstellar capabilities. A space-faring civilization could conceivably use such constructs to occupy much or all of the Milky Way galaxy and perhaps the entire universe. This paper presents several reasons that a civilization might decide to produce and deploy Von Neumann probes. Physically possible interstellar propulsion methods for such devices are discussed, as is a launch strategy minimizing the duration of an interstellar transfer. Various solar system locations could be investigated to determine whether Von Neumann probes are present in our vicinity.

冯·诺伊曼探测器:原理,推进,星际转移时间
冯·诺伊曼探测器是一种具有星际能力的自我复制智能装置。可以想象,一个太空文明可以使用这样的结构来占领银河系的大部分或全部,甚至整个宇宙。本文提出了一个文明可能决定生产和部署冯·诺伊曼探测器的几个原因。讨论了这种装置在物理上可能的星际推进方法,以及最小化星际转移持续时间的发射策略。可以对太阳系的不同位置进行调查,以确定冯·诺伊曼探测器是否在我们附近。

期刊介绍: International Journal of Astrobiology is the peer-reviewed forum for practitioners in this exciting interdisciplinary field. Coverage includes cosmic prebiotic chemistry, planetary evolution, the search for planetary systems and habitable zones, extremophile biology and experimental simulation of extraterrestrial environments, Mars as an abode of life, life detection in our solar system and beyond, the search for extraterrestrial intelligence, the history of the science of astrobiology, as well as societal and educational aspects of astrobiology. Occasionally an issue of the journal is devoted to the keynote plenary research papers from an international meeting. A notable feature of the journal is the global distribution of its authors.
