摘要

费米悖论的解决方案要么否认外星人的存在,要么提供其他理由来解释没有发生第一次接触。而后者,更乐观的方法通常假设外星人的存在,他们同时暗示有限的未来可探测性。如果费米悖论的解决方案被认为是正确的,那么必须根据它们如何影响未来SETI努力成功的可能性来评估它们。一些解可能会导致所谓的费米约束:为了解释为什么到目前为止还没有任何接触,费米悖论的乐观解必须接受这样的假设:如果假设解是正确的,则表明未来接触的概率非常低。换句话说:它们不在这里,这就是它们可能永远不会出现的原因。

Where will they be: hidden implications of solutions to the Fermi paradox
Abstract Solutions to the Fermi paradox either deny the existence of extraterrestrials or offer alternative reasons to explain the non-occurrence of a first contact. While the latter, more optimistic approaches generally assume the existence of extraterrestrials, they simultaneously hint to limited future detectability. If solutions to the Fermi paradox are accepted as true, they must be evaluated in terms of how they affect the likelihood of success of future SETI efforts. Some solutions may lead to the so-called Fermi constraint: in order to explain why there has not been any contact so far, optimistic solutions to the Fermi paradox have to accept assumptions that, if the solution is assumed to be correct, indicate a very low probability of future contact. In other words: they are not here, and that is why they may never appear.

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.
