decade of 1950, the Cold War strategists contemplated the idea of \u200b\u200ba gun the day of Judgement, a weapon so terrible and uncontrollable that was capable of destroying every vestige of human life on the face of the Earth. Thus, if the enemy knew that you are willing to make use of a device so devastating, even dare to attack. Probably, the American writer Fred Saberhagen had in mind the gun the day of Judgement when he wrote his stories about berserkers. The berserkers the stories of self-replicating machines are Saberhagen whose mission is solely to ending all forms of sentient life. One similarity that could be established to imagine is to see them as probes Bracewell-von Neumann , but with an air of meanness, machines are prepared to kill and kill and kill.
Thus, the relevance with respect to the Fermi paradox seems clear: the CETs may be besieged by berserkers, or worse, have been killed by these, or may not dare to reveal their situation fear of being detected artifacts murderers. It seems a relatively elegant solution of the paradox. Now, it has overtones of reality, or is it just pure science fiction?
If CET managed to build probes capable of colonizing the galaxy, then, unfortunately, turn them into berserkers would not be too far out of reach. Anyway, it is hard to imagine a race or wants to develop technology intelligent species berserker, as this technology is so dangerous to the creators and for any other kind of life. Also, what could be his motivation to build such devastating weapons? If your propórito would colonize the galaxy, could take place simply by being the first to do: remember that the time of colonization required is well below the age of the galaxy. However, we should not show too optimistic about the possibilities of the berserkers. Assume that the scheduling of a probe "tight" mutase. Perhaps a chance collision with a cosmic ray lost changed the code line where it says "seeking new ways of life and possible civilizations" with another saying "looking for new ways of life possible civilizations and ends with them." Inevitably evolve self-replicating probes and, therefore, seems highly unlikely that berserkers also appear spontaneously sooner or later.
Assuming the berserkers can be considered more critical. Even admitting that there were, could inevitably be a nemesis? Could not the CETs inoculated themselves, as they would against a virulent disease? Moreover, the berserker stage includes in itself a Fermi paradox: if there are, what we're here? The berserkers and should have sterilized the planet. In contrast, the geologic and fossil records indicate that life has been present on Earth for millions of years. There have been several mass extinctions and they all have perfectly natural explanations. The universe is already a dangerous enough place without berserkers. So why do they have silenced us and other civilizations have left us in peace?
Arguably berserkers only destroy the life forms with a certain technological development and need an "apology" (presumably, the detection of radio waves, for example) before shooting. But this extra step in the argument all it does is ruin what potentially is an elegant solution to the Fermi paradox. After all, if the berserkers are all that are supposed to be, where are they?
