Stephen Hawking, the noted physicist, has expressed an in-depth personal fear of aliens, so much so that he hinted that we should stop looking for them, stop sending out signals to keep our existence a secret, less the aliens discover us and come here to wipe us out. This information will discuss whether this viewpoint has any merit.
The North American Indians, the South American Indians, the Africans and others, all had something very real to fear if the Europeans got to their land, so it will be understandable that earthlings, like Hawking, might fear aliens arriving at this planet. This fear stems mainly from superimposing human mentality on the aliens, not forgetting watching way too many Star Trek and Star War movies. Naturally, it is really mandatory for Hollywood to turn the aliens into man-eating predators for purely business reasons: carnivorous aliens sell more theater tickets than benevolent aliens.
There is, however, a noticeable distinction between Europe and also the other continents on the one hand, and between Alien Spacecraft and Earth on the other. The distinction is distance. To reach another continents, the Europeans only needed some relatively primitive sailboats. But for the aliens to reach Earth, dozens or numerous light years away, they would need quite sophisticated spacecraft. The critical question, therefore, is: Can a barbarous civilization develop higher technology?
Human history fails to support the concept it is feasible for barbarians to attain higher technology. Two of the most barbarous epochs in human history were a) the thousands of years preceding the dawn of civilization, and b) the thousand-year period after the fall in the Roman empire. Both in epochs, technological progress was virtually nil. Only when human civilization became less barbarous, using the demise of rule by hereditary delinquents referred to as royalty, with all the demise of slavery, using the spread of education towards the masses, and so on, do we commence to see technological progress.
For sure, there could be complete degenerates out in space but they must be absolutely nothing to fear since it is unlikely that they may ever be able to leave their particular planet much less survive the nuclear weapons stage if they ever get that far. Technological barbarians, such as the Klingons of Star Trek, may possibly exist in Hollywood and nowhere else. Now another question arises: Are friendly aliens something to fear?
Some have suggested that contact with aliens would result in a dramatic upheaval in human society. My personal opinion about this is: Not really. Perhaps decades ago there might have been some commotion although not today. More than sixty many years of ancient astronaut and UFO propaganda has produced a world where alien contact may turn out to be just another news event. With regards to “upheaval,” I will think of three things which might happen:
1) The armaments industry may be affected. Knowing advanced alien civilizations exist, chances are that humans will want to bind together being a species and can stop killing the other person. Indeed, it appears virtually certain that wars between humans should come for an end, and the countries in the Middle East will finally make peace. Jobs in the armaments industry would need to be moved to infrastructure, space exploration, and consumer-related industries.
2) Social structures may be affected. Disparities involving the developed world as well as the third world may start to melt away as well as other inequities in human society. We are going to likely see higher taxes on the usvyot and a lot more awareness of education, technological development, as well as the colonization of outer space.
3) Organized religions may be affected. Fundamentalist concepts like creation could be pushed in to the background, but overall, religions may carry on and proliferate as a mechanism for consolation and moral guidance.
Hawking acknowledges that aliens may have extremely advanced technology. The key flaw in his thinking is not realizing that such technology may be used to find ways of self-sustenance excluding the barbaric plundering of inhabited planets. The opportunity that SETI (Look for Extraterrestrial Intelligence) will ultimately pick up an alien signal is nothing to fear and, for the contrary, could even be something to welcome.
