论文摘要
迄今为止，寻找外星智力（SETI）是一种被动的练习，依赖于追求技术签名。尽管如此，有些人提倡采用更积极的方法。消息传递外星智能（METI）在较大的SETI项目中具有有争议的历史。据称，涉及的风险大于任何潜在的收益。这些论点最终并不令人信服，导致荒谬的政策建议，并基于对技术签名性质的错误欣赏，其可检测性意味着发信号的意图。目前的技术正在迅速发展，以至于我们很快就会拥有巨大的观察覆盖范围，以便可靠地检测到这种技术签名和生物签名：可以匹配或超过其他地方的能力。为了逃避正确定义的SETI悖论，至少一个技术文明必须选择不抑制其自己的天体生物学信号连续体，其中Meti只是最有效的终点。被动SETI在短期内取得成功的可能性很小，这是可持续资金的严重障碍，以及通过对接触的有害恐惧增强的“咯咯笑因素”。科学界必须整合一种积极的方法，以更好地确保SETI项目的连续性和最终成功。
The Search for Extraterrestrial Intelligence (SETI) has heretofore been a largely passive exercise, reliant on the pursuit of technosignatures. Still, there are those that advocate a more active approach. Messaging Extraterrestrial Intelligence (METI) has had a controversial history within the larger SETI project; it is claimed that the risks involved outweigh any potential benefits. These arguments are ultimately not compelling, result in absurd policy recommendations, and rest on a faulty appreciation of the nature of technosignatures, whose detectability implies intent to signal. Present technology is advancing quickly such that we will soon have great observational reach, to the point of reliably detecting such technosignatures and biosignatures: a capability that can be matched or exceeded elsewhere. To escape the SETI Paradox properly defined, at least one technological civilization must choose not to suppress its own continuum of astrobiological signals, of which METI is merely the most effective endmember. Passive SETI's low likelihood of success in the short-term is a serious obstacle to sustainable funding, alongside a 'giggle factor' enhanced by a pernicious fear of contact. The scientific community must integrate an active approach to better ensure both the continuity and eventual success of the SETI project.
