新颖的技术签名

Novel Technosignatures

A. A. Jackson, Gregory Benford

摘要:

技术签名可以代表一种技术迹象,可以推断宇宙其他地方存在智慧生命。这通常意味着使用窄带无线电信号或脉冲激光搜索外星智慧。早在1960年,弗里曼·戴森就提出了这样的想法:先进的文明可能会建造大型结构,以捕获并使用其本地恒星的能量,从而产生一种具有不寻常红外特征的物体。后来人们注意到,其他物体可能代表着非常先进的工具的特征,例如星际飞行器、用于推进的光束站、不使用无线电或激光辐射而是发射伽马射线、中微子或引力辐射的不寻常信标。迹象可能是无意的,也可能是直接的。在定向和非定向的迹象中,我们提出了一些信号和副产品辐射的模型,这些信号和副产品辐射可能是由极其先进的社会产生的,而这些社会在寻找外星智慧时通常不会被考虑。

英文摘要:

Technosignatures can represent a sign of technology that may infer the existence of intelligent life elsewhere in the universe. This had usually meant searches for extraterrestrial intelligence using narrow-band radio signals or pulsed lasers. Back in 1960 Freeman Dyson put forward the idea that advanced civilizations may construct large structures in order to capture, for use, the energy of their local star, leading to an object with an unusual infrared signature. Later it was noted that other objects may represent the signature of very advanced instrumentalities, such as interstellar vehicles, beaming stations for propulsion, unusual beacons not using radio or laser radiation but emission of gamma rays, neutrinos or gravitational radiation. Signs may be unintentional or may be directed. Among directed and undirected signs we present some models for signaling and by-product radiation that might be produced by extremely advanced societies not usually considered in the search for extraterrestrial intelligence.
