论文摘要

提出了一个公式,以定量估计银河系中通信外智能文明(CETIS)的信号排放率。我建议一种可能的CETI信号将是类似于快速无线电突发(FRB)的简短无线电爆发。数十年来,对银河系中类似FRB的人造信号的专门搜索可能对CETIS的这些信号的发射率有意义。 Fermi-Hart悖论的回答是没有足够的观察时间和其他类型的信号。简要讨论了人类是否应该在未来发送类似FRB的信号。

A formula is proposed to quantitatively estimate the signal emission rate of Communicating Extra-Terrestrial Intelligent civilizations (CETIs) in the Galaxy. I suggest that one possible type of CETI signal would be brief radio bursts similar to fast radio bursts (FRBs). A dedicated search for FRB-like artificial signals in the Galaxy for decades may pose a meaningful upper limit on the emission rate of these signals by CETIs. The Fermi-Hart paradox is answered in terms of not having enough observing times for this and other types of signals. Whether humans should send FRB-like signals in the far future is briefly discussed.
