Contribution
It introduces a framework for understanding the success factors in SETI, focusing on civilization lifetimes and probabilistic estimations of signal detection.
Findings
Civilizations' lifetimes are crucial for detection success
Estimated minimum number of co-existing civilizations
Probability of detecting extraterrestrial signals
Abstract
In this article an analysis of the fundamentals used to search for extraterrestrial artificial signals in the galaxy, which have been developing for more than five decades, is presented. It is shown that the key factor for the success of these research projects is given by the technological civilizations lifetimes. Assuming the Principle of Mediocrity, estimations are made to determine the minimum number of civilizations that may co-exist in the galaxy and the probability of detecting a signal from them.
