How to find aliens?

In the search for extraterrestrial mass understanding inextricably linked to the UFO, which are carefully collected information on UFO sightings, contacts of people with extraterrestrials who allegedly visited Earth, and even themselves trying to get in touch with them.

Where it is known that the problem of extraterrestrial intelligence is one of the biggest scientific challenges, which was first staged in the XVII century. Above her were outstanding scientists. Few people know the fact that in the USSR the search of extraterrestrial civilizations underway since 1964.

A closer examination of the problem of finding extraterrestrial intelligence shows that many eminent scholars attached great importance to this matter. This gives us reason to believe that the subject of aliens is not only giving freaks.

In what follows, we will use instead the term "aliens", tracing English words aliens — strangers, which, from our point of view, which more accurately reflects the nature of the topic. We do not know anything specifically about other people, and there is no guarantee, for example, that the place of their habitation, in fact, are the planet.

Search for alien as bad

First search for extraterrestrial intelligence began in the U.S. with the project radio astronomer Frank Drake "Ozma", which in 1960 conducted a search for artificial signals from the stars Tau Ceti and Epsilon Eridani, which are separated from the Earth by a distance of 11 light years.

In the USSR, the search was launched after the book IS Shklovsky's "universe, life, mind." Was formed Union conference on extraterrestrial civilizations, on whose advice in 1964 in the USSR Academy of Sciences was created section "Search for signals from extraterrestrial civilizations," which operated until 1987.

Despite the efforts and numerous methods are tried, no convincing signs of alien has not been found. Optimists among participants SETI, say that any little bit of an alien civilization has come to create systems and radio and radar signals, which enable them to detect a minimum of 100 light years. But tested only 0.1% of the promising stars and nobody can guarantee that 99.9% among the other stars no signals alien civilization.

By the way, mankind itself shows its presence powerful radio emission originating from both the communications and the broadcasting and radio telescopes work, which is comparable to the radio emission of the Sun, and in the past even exceed it. From the point of view of observers from the depths of space, about 70 years ago in the Solar System has been some astronomical event which resulted in the radio emission from star has risen dramatically. If other people are also looking for other civilizations in space, they can find on this earth is a powerful radio emission.

Skeptics argue that the negative result of the search of others is natural, since in the vast space, infinite time and space, and different civilizations just do not intersect.

Space must be habitable

All of our current knowledge about the cosmos suggests that intelligent life in the universe should be fairly common and banal phenomenon. The fact that the Sun is very common for the Galaxy star G2 «yellow dwarf." These stars just in our galaxy, probably more than a dozen billion. If we assume with other galaxies, the number of these stars have to be huge.

The similarity of a number of stars to the sun led to the suggestion that these stars must have solar systems that can be inhabited. These hypothetical planet called exoplanets. This assumption was made in 1916 by Edward Bernard, but the first extrasolar planet was discovered in 1991 by astronomer Alexander Volshchanom a neutron star PSR 1257 +12. In 1995 it was discovered a large planet in the star 51 Pegasi. The vibration of the stars, exoplanet should be large as Jupiter, but located close to the star. By November 2007 260 exoplanets discovered 220 planetary systems. Now, the discovery of new planets is about once a week, and sometimes more.

Exoplanet discovery was the first step to finding someone else's mind. The second step was the discovery of the planets, the conditions are close to the earth. Because that's earthly conditions, the representations of modern science, is considered the most suitable for life. In 2004 in a star system Mu Altar was discovered the first planet in the parameters close to the Earth. Now obtained photographs of exoplanets (eg, a gas giant in the star Epsilon Eridani) and it is expected that soon will be available to scientists equipped to investigate the chemical composition of the atmosphere of exoplanets and discover extrasolar planets with nitrogen-oxygen atmosphere.

Resulting from modern conceptions of the universe is isotropic assumption of "non-unique" Earth, finding more and more evidence. Humanity is left to do three steps in finding another reason: the first — to find exoplanets with an oxygen atmosphere and water, the second — to detect exoplanet life, the third — to discover just another reason.

Aliens do not exist, and that could be the reason

But as long as space is silent, and there is no proven evidence of the existence of another mind. In an attempt to resolve this contradiction, created several hypotheses about what is called "non-existence" of others.

The first, and most likely version is that the emergence of the mind, of course, happens regularly, but the universe is so boundless in space and time, we just do not intersect with outsiders. This hypothesis suggests that what we find in space — it's some weird artifacts age in millions of years, which for us are completely useless.

But here the question arises, why, then, we do not see a civilization that existed millions of those same years. To this question is a preliminary response data of biological evolution, according to which the life of a successful species, able to give a reasonable life, limited to only a few million years. While a number of species, such as sharks and crocodiles, there are hundreds of millions of years, and even more, but, alas, they are unreasonable. Most likely, the life expectancy of foreign civilizations is also small, and we are, at best, we find some of its residues.

From the void of the universe around us, we can also draw conclusions and that, and humanity in its current form is very unstable.

Traces of alien

As already mentioned, the traces of others yet to be found. But this does not mean that nothing can be said about the places where they are likely to be. In terms of leaving traces, others come in two varieties.

The first kind — is strange, to some extent coincide with human notions about them. That is, it traces left by some intelligent race, but who still have something similar to the technique in our understanding. The existence of just such a strange point of view of modern ideas is just the least likely, but it can not be discounted.

Where to find them? First of all, certainly not to look for on other planets, and even more so in the world. The atmosphere and the biosphere over millions of years has destroyed almost every conceivable material. Accordingly, the traces of these other people can only stay in space. And if you specifically, the most likely location of the artifacts are the Lagrange points, where the attraction of the sun and planets are balanced. By the way, the three terrestrial object located in Lagrange points.

The second type — others, dramatically surpassing earthly level, and do not have anything remotely resembling any technique. Naturally, when it comes to technology, transcending earthly many orders of magnitude, it is meaningless on the basis of our technical level suggest what can and what can not be alien technology. But the method of searching, however, exists. This search anomalies. After examination by the solar system will find out what natural phenomena are common to it, it makes sense to focus on those events that are knocked out of this series. Thus, if these aliens left in your system artifact, there is a chance to find it.
Philistine ideas about other people

Naturally, highlighting the theme of others, you should still mention what attitude to have this strange reasoning ufologists. Let us say at once — no. Modern ufology is a good field for the study of human prejudices and in this respect is very interesting.

Large factual material accumulated by ufologists, where complete strangers to each other people, not having this benefit, and having problems with the same words (often describe the same even in the details), about alien encounters, at first glance impression. Are there such cases? Have. Do contact relation to reality? Have. But the conclusions of the facts should be made not those which make ufologists. Ufologists from this it is concluded that there are other people visiting Earth.

However, it is striking that the flow of UFO relatively recent age and known, when they started. First UFO and dynamics of observations coincide with the start of the Cold War. The first report of a UFO — it's 1947, the year Fulltona and Churchill's speech. It would be really strange to assume that it is this time others have chosen this time to begin penetration. In the middle ages people have seen angels in the modern era — the ships, in our time — a UFO. Such a strong correlation with the mass appearance of art perception of outsiders, show that ufologists turns everything upside down. UFO reports — a reflection of the global socio-psychological processes in the societies of the European type, especially in the U.S. and Europe. We do not know how it is explained.

Logically correct conclusion is: contacts with different names such as they are shown ufologists, because that is the representation of the mass psychology of them. Because before they flew on sailing ships in the sky, then at superdirizhablyah in our time "flying saucers." This explains the paradox that the accumulated information about tens of thousands of observations and contacts, but not found any tangible evidence, no artifacts, even the smallest, which would have proved an extraterrestrial origin.

Will there be a war with other people's?

A favorite theme of science fiction and some ufologists, after the great novels of HG Wells' War of the Worlds "is a war of humans with strangers. It is difficult even to list how many times and for what reasons addressed this topic.

But that's the current state of understanding of the cosmos and the state of research into alien civilization exclude this possibility. If earthly or alien civilization will reach a level of development that will be able to overcome in a relatively short time, the distance of tens of light-years (hundreds of trillion. Kilometers), for her other intelligent life forms will be represented unless scientific interest, since by that time all of the economic and energy issues will be resolved for a long time.

Not the fact that if the Earth's civilization will be able to reach the exoplanets with someone else's life, she will find it mind and civilization, not the ocean from the simplest organisms, not the biosphere populated by irrational beings. Not the fact that humans do not face on exoplanets with something huge and incomprehensible, like "Solaris".

In other words, in a situation of conflict and war need to earthly and alien civilization were roughly comparable level of development, which, within the framework of current thinking, it looks highly unlikely.

Not be amiss to mention here, that is not even theoretically possible to provide only the highest achievement of the nearest stars. But space is huge, and the size of our galaxy in the modern view is about 100,000 light-years across and about 1,000 light-years thick. How to overcome these distances, even in theory, now imagine it is very difficult. Most likely, the vast distances and are an obstacle to foreign intelligence.

Most likely, if we are and make contact with other people's minds, it is only remote, that would exclude any possibility at all is not that conflict, and all conflict. Possible conflict, you can allow a simple off receiving and transmitting equipment.

Why do we need the aliens?

In the popular view other people have a high level of technology, which humans can learn from, which is why ufology studiously exaggerate about what contact with other people for a long time engaged in secret government of different countries, especially the U.S., for military purposes.

However, the most likely other people who can get to the Earth, have such a high level of technology that humans will be unable to take over, but even to understand the principles of operation of these devices. Or we get a long time out of order artifacts, working principle and the purpose of which we will also be clear.

In all of this, others have some practical significance for humans. We now live largely in exciting times. The idea of the unity of mankind, which was for centuries and millennia property only its best representatives, is now becoming a reality. Of course, the world of globalization — is not the world of utopia, there are also a lot of drawbacks. But perhaps it is extraterrestrial alien lacks humanity, the enemies of the submissions, typical of our culture has found its external manifestation. Perhaps it is not strange enough for us to "us" to reach all humans indiscriminately nationality and race.

This point was reflected in a number of science fiction films. For example, in the film by James Cameron "Aliens" Ellen Ripley in the beginning threw a tantrum over the fact that the crew of a rescue mission was a robot android. But after a fight with someone else, her hatred of androids gone. Also seem to be on Earth. Anyone own ingrained white racists who desperately hates people of other races, after a personal acquaintance with the stranger, the Zulu of South Africa seem brother. Aliens deliver a decisive and irrevocable end to the existence of any doctrine of racism and nationalism, dividing humanity.
