In one, we can live "Galactic ecosystem"? As soon as we are a real space faring, developing interstellar race, we are joining resources in other alien species in the competition for the bounty of our Galaxy?
Such a competition humanity could define as a heavyweight milky way? Or due to our readiness ", aliens to reach", we get may be eradicated, assimilated/eaten faster than we can say, "You have Stephen Hawking right!"?
Should only quiet, we stay with our neighbours ET us like?
Analysis: Asteroid forensics can point to foreign space miners
This scenario is by Adrian Kent of Perimeter Institute in Waterloo, Ontario, Canada, thought is, in a paper on the ArXiv titled, suitable, "to damn quiet?"
Why we decades hear an extraterrestrial civilization, despite of a signal tell-tale discovered not known as the "Fermi paradox." If Advanced extraterrestrial civilizations are out there, post still not why they are now?
Kent think he know why: perhaps only the wiliest alien survive the interstellar version of evolution. Survival of the fittest, in this context means, that to make it in the milky way of hard beats, you need to keep your head to.
Funds remain calm, avoid the attention of the potentially aggressive alien species, and thereby ensuring survival.
It could be quiet, that the most advanced extraterrestrial civilizations are actually naturally? Is this why we haven't heard of them?
Perhaps, but I suspect there may be other, simpler explanations. Perhaps still not the signal of ET is recognized. Also, we probably need a larger, more sensitive listening device, such as the SETI Allen Telescope array given recently commissioned. The earth can in a populated part of the milky way, which means that we may experience a different alien intelligence not for a long, long time, if any exist.
In a 2009 study, Reginald Smith of Bouchet-Franklin Institute, Rochester, New York, said that ET's could affect radio signal, too weak to determine in which natural radio background noise. As well, our attempts at messaging extraterrestrial intelligence (METI) reach not very deep into the room with the transmitting technology we currently have.
Therefore, it must transfer a minimum number density be civilizations in our Galaxy for everyone to hear.
In a Astroengine.com blog on this subject, I concluded:
... unless our Galaxy has about 300 civilizations, each transfer (for over 1000 years), there is a very high chance that (except some who lived very close together this advanced alien civilizations) no two civilizations ever can know the existence of someone. Huge Galactic distances combined with signal degradation leads to a situation where, if communication civilizations statically, within your that stay home star system without interstellar travel, alien relations always unlikely remain likelihood of smithing.
Kent admits that the discussion of the nature is a hypothetical au?erirdischer-- let alone the potential existence of foreigners, of which k?nnte-- kill us is pure speculation.
Although the idea of the "stay quiet to avoid destruction" made popular was by Stephen Hawking in last year's Discovery Channel documentary "in the universe", it is also the argument that, if we make any contact with sufficiently advanced aliens, perhaps our survival in the milky way pretty much limited without the aid of technology on our own.
It is a "damned if you do, damned if you don't" situation. We have no idea if there are any foreigners are. We could be the only forms of life (so far, there is little evidence otherwise) in our entire Galaxy. As well, we could include in a galactic ecosystem, where alien civilizations for resources compete, coexist and develop accordingly.
If the latter is true, we should keep our collective mouth closed until we develop into a force which be expected? Who knows.
