Manifestations of any advanced civilization indistinguishable from natural phenomena or why we do not see the aliens can we really do not see the aliens because the manifestations of any advanced civilization indistinguishable from the phenomena of Nature. But then I wonder why they have so far not corrode space Dostum?
Val exoplanet discoveries exacerbates a long-standing problem of astronomy. Or even this: the Fermi paradox is becoming more and more ironic.
Only in our own galaxy, at last count, at least 100 billion planets. But in fact all of this self-deception, as used today exoplanet detection methods eliminate the possibility of not only a new look for Mercury, but most of the planets the size of Earth. In addition, even our modest civilization has already sent out of the solar system five probes (like the same Voyager). They will always fly in interstellar space, until they enter the gravitational field of any star.
Consequently, hundreds of thousands of years of civilization and development of the current earth just simply has to flood the space such devices, constantly sending radio signals into space.
According to the calculations presented in a recent paper by astronomer Keith Wiley of the University of Washington (USA), such probes have been hit in the solar system long before the origins of humanity and the Earth, no doubt, is the main object of their research. Analysis of this study, as well as related issues devoted to fresh material in Discovery News, the presentation of which we offer.

So, for the development of civilization in the population of 100 billion exoplanets had plenty of time (the sun is not out of the oldest stars). And therefore the Galaxy must literally crawling with aliens. But all the efforts of the project SETI astronomers and others have not had the results.
Their main result was the statement of the so-called Great Silence.
A long time - even before SETI - suggests that the radio communication with extraterrestrial civilizations like the African savages trying to make contact with their gods, bringing them to the victim. It is not known whether they will respond to the sound of drums, whether they involve fresh antelope, as well as whether there are any. Now the existence of extraterrestrial life is more like a statistical inevitability. As stated at the time Seth Shostak, head of SETI, will be a miracle if they are not discovered.
But the wonder of it?
By assumption, Karl Schroeder, it is quite simply that, technically advanced aliens are using technology with very high efficiency, low energy expenditure side, which do not require infrastructure that is easy to detect. In other words, he believes that the manifestation of any sufficiently advanced civilization indistinguishable from the phenomena of nature. Aliens can enjoy the unmanned surveillance drones, which we simply do not see, because may be the size of a beetle or a bacterium. And biorobots alleged spy may have a better mimicry chameleon. Frankly speaking, this means that we should not even try to detect the presence of extraterrestrial civilizations.
It is useless as trying to find a reconnaissance spy satellite in geostationary orbit, taking advantage of the technical means of the Roman Empire.
Well, the West is West, and the information-it is not closer to the East than in the days of Kipling. And it's not that Schroeder word for word described Leonid of them have not read the novel, Noon, XXII Century by Strugatsky.
Our readers will remember the much earlier explanation of the Fermi paradox fantastomStanislavom Lem. In his mind, we just accept artificial interstellar medium for the natural as well as laboratory white mice make mazes for an integral part of the world. Reformulating Schroeder, it turns out that all the phenomena of nature next to a well-developed civilization may be the result of the latter. Thus, the average Dutch reasonable mouse does not know that he lives on the dry seabed.
Do not guess, until she will develop the technology inning of land from the sea.
Meanwhile, a certain level of civilization left no trace as radio and clouds of smog. Difficult for us to think up traces of their life, because we simply do not present their technologies. But it's quite possible that black holes - their Chernobyls and Fukushima, and dark matter, tormented by the mysteriousness of astronomers - their cemetery of radioactive waste. Sami supernova explosions and even pulsars and quasars, whose nature is mysterious, too, can be humdrum production processes, some trudnopredstavimym power reactor.
But for the study of humanity can be, for example, the Moon: it is, by the way, is perfectly consistent with the fact that it is constantly turned to the Earth on one side.
Even people smart enough to implant in the test animals GPS-sensors and other research equipment. It is clear that super-civilizations can start this process on an industrial scale by introducing bioustroystva observations in all individuals of the type being studied. After all, not even a single neurophysiologist not give a clear answer to the question of why a person uses to higher nervous activity as a fraction of their brain.
In fact, the explanation of Stanislaw Lem is in better agreement with the history of mankind. What is b? Lshih successes we have achieved, the higher the trash heap in human settlements. Mammoth hunters from the air it would be difficult to distinguish (in the sense of whether they are of civilization) of beavers with their dams.
Most importantly, we use energy is such that it can not be hidden, like the fires that have burned our ancestors in caves.
And why? Schroeder's assumption that in the long run, survive only civilization that are in balance with nature, is not consistent with our historical experience. Pygmies in the rainforest did not destroy any kind as the Bushmen of the Kalahari Desert.
But civilization dominated the race, they did not.
