The possibility of finding traces of extraterrestrial intelligence on asteroids.
Abstract
To explain the lack of the extraterrestrial radio signals and the Fermi paradox, a dual development path is described for the technical civilisations originating on Earth-like planets. One part of the civilisation remains on the planet and its technological level starts decaying after a time (exhaustion of resources etc.). The other part of the civilisation reaches the technological level of the interstellar spaceflight, but those who leave on interstellar spaceships never return to any planet because this would mean returning to a lower level of technology (i.e. a lower standard of living). It is suggested that such self-sufficient interstellar spaceships may use near-Earth asteroids as a resource base for self-repairing of self-replicating purposes, and explained why such visits in the solar system are rare events which do not last long. The possibility of detecting traces of such activities is discussed.
