Calculations conducted by researchers from Cornell University show that even if humanity is the only intelligent civilization in space, the next brothers in mind from us located at a distance of not less than 1 500 years. This means that, in all probability, the first contact earthlings with aliens will take place in patarra tysyacheletia or even later. According to the researchers, their findings help to explain the famous Fermi paradox.
The Fermi paradox is that the lack of observable traces of the existence of extraterrestrial super-civilizations, by and large, is pretty amazing: during the existence of the Universe it is, from the point of view of modern scientific knowledge, could be formed on earth-like planet and settle in space. The fact that this civilization we are, however, not observed, may indicate that either our understanding of nature or our observations are incomplete and erroneous.
According to researchers, within one and a half thousand years, the signals from the Ground, many of whom are ordinary television signals and radio signals, will fly a considerable part of the milky way and the potential representatives of extraterrestrial civilizations will be able to understand where to find the earthlings, and probably to send a “response”. Already today the signals were to reach 8 531 a famous star and 3 555 open planets like Earth. However, the chances that aliens would be on these planets, according to astronomers, is very small. However, only in the milky way is about 200 billion stars, so that over time the chance to exchange information with the aliens from the inhabitants of the Earth is increasing.
In General, the study leader Evan Solomonides looks at the prospects for the discovery of other civilizations with considerable optimism, although waiting contact with them only in the distant future. “We live on the third planet orbiting a rather boring star surrounded by other perfectly normal stars in one of the arms is surprisingly average spiral galaxy. We are not in any unique point in the Universe, so we’re not necessarily unique,” says Solomonides.
On their findings, the scientists reported at the annual meeting of the American astronomical society. By the way, at the same event, recently announced the opening of the largest known exoplanets orbiting a double star.Related posts:
