from the Chiasmus archive: October 16, 2013. "FERMI PARADOX (PART 4) - GALAXY SHUTDOWN AKA "LOOSE LIPS SINK SHIPS"


 This one is good,  it's a premise that the reason we are not detecting any radio signals or other forms of extraterrestrial contact is that the universe is amidst a communication shutdown.  No one is transmitting, sans only us -  the naive, humans, as we continue sending out signals, when really we should be just listening - possibly like other alien civilizations out there.  Why?  We could be transmitting to an alien race that is warlike.  That our penchant for naivety is the assumption of a higher cosmic moral ground; a friendly alien race.  We could be wrong.  Hence the reason why it's very quite out there.

We can not assume that we already have been detected or that detection is inevitable. Extraterrestrial civilizations might not be looking for the kinds of signals we normally radiate. More importantly from a policy perspective, our leakage signals may be below their detection threshold. An Active SETI signal much more powerful than the normal background emitted by the Earth might call us to the attention of a technological civilization that had not known of our existence. We can not assume that such a civilization would be benign, nor can we assume that interstellar flight is impossible for a species more technologically advanced than our own.

This is not just the concern of a few paranoids. Many significant people have argued against our actively seeking contact. Pulitzer Prize-winning author and scientist Jared Diamond, calling astronomers’ visions of friendly relations "the best-case scenario," warned that "those astronomers now preparing again to beam radio signals out to hoped-for extraterrestrials are naive, even dangerous" (he was even harsher about the Pioneer plaques, which provided any species that found them with a kind of map to our location in the galaxy). 

Nobel Prize-winning biologist George Wald declared that he could think of no nightmare so terrifying as establishing communication with a superior technology in outer space. Even the New York Times questioned the view that the effect of signals from extraterrestrials would be beneficial, stating that the astronomers were "boyishly defiant" of our inherited wisdom.

Astronomer Robert Jastrow, addressing the consequences of possible future contact with an alien civilization, wrote that he saw no reason for optimism. Astronomer Ronald Bracewell warned that other species too would place a premium on cunning and weaponry; an alien ship headed our way is likely to be armed.  Astronomer Eric Chaisson thought that physical contact could lead to a neo-Darwinian subjugation of our culture by theirs. Astronomer Zdenek Kopal was more specific: should we ever hear the space-phone ringing, for God’s sake let us not answer, but rather make ourselves as inconspicuous as possible to avoid attracting attention!

Other scientists who are less widely known have warned of potential dangers. Biologist Michael Archer said that any creature we contact will also have had to claw its way up the evolutionary ladder and will be every bit as nasty as we are. It will likely be an extremely adaptable, extremely aggressive super-predator. Physicist George Baldwin predicted that any effort to communicate with extraterrestrials is fraught with grave danger, as they will show innate contempt for human beings. Robert Rood warned that the civilization that blurts out its existence on interstellar beacons at the first opportunity might be like some early hominid descending from the trees and calling "here kitty" to a saber-toothed tiger.

Consider the cautionary views of SETI Institute astronomers. Seth Shostak wrote in one of his books that we can no better guess the motivations of alien intelligence than goldfish can guess ours. Jill Tarter asked rhetorically: who knows what values might drive an alien culture? Aliens might not have the same motives we do. Doug Vakoch wrote that we should not assume that the ethics of extraterrestrials will be like our own.

Physicist Freeman Dyson has written eloquently on this subject. He issued a warning that should be heeded by SETI researchers: "Our business as scientists is to search the universe and find out what is there. What is there may conform to our moral sense or it may not...It is just as unscientific to impute to remote intelligences wisdom and serenity as it is to impute to them irrational and murderous impulses. We must be prepared for either possibility and conduct our searches accordingly."
