Alien life in Antarctica
Alien life in Antarctica
Habitat for all living beings on Earth is a thin hard shell, like a shell covering the entire surface of the planet - the lithosphere. The depth of its ranges from 70 kilometers under the greatest mountain ranges, up to only 5-7 kilometers under the ocean basins. Although for the life of the significance of this layer of the Earth's structure can not be overemphasized, by weight, he is only about 1% of the total mass of our planet. The total elevation change (and depths) in the lithosphere is not so great, even compared with the "kid" Mars. It is the highest ever found in the solar system Mountains - Olympus, a height greater than 26 km. On Earth, the difference between the highest mountain and deepest ocean trenches - only about 20 miles, which, however, does not make these areas are very accessible to human exploration.
The composition of the lithosphere, with all the achievements of technological progress, remains a subject of debate. It is not surprising that scientists can speak only at the level of hypotheses about the structure of other planets and their satellites - even the bowels of the Earth can be studied only by indirect methods. So, in essence, the picture is the Earth's crust - also quite virtual.
Offices of deep drilling
To this day, drilling rigs could not reach the mantle, with all the zeal with which the development took place. Until 2008, the deepest in the world is Kola borehole, a draft of which was proposed in 1963 and work began in 1970. Drilling was carried out until 1995, then continued up to 2008 different kinds of experiments with electromagnetic and other fields of the Earth and the Sun, and in 2008 the project was shut down permanently. In addition to being allowed to change the drilling of the structure of the cortex (shown in the illustration layer of basalt on the Kola has not been detected, they found water, bacteria and methane deposits, which refutes the theory of organic hydrocarbon resources), work well, as in other similar objects are constantly accompanied by a mystical event.
The main event began to develop after the drill depth of 10 km - first tool is double fused, although the sensors are not nearly reached the temperature at which it could theoretically happen. Then the tip was completely torn off, and as a result of a sharp jerk, and the subsequent drilling should be kept to a cable has not been found. The apotheosis of weirdness inspired the cessation of work, became an underground explosion of unknown nature at a depth of 12,262 meters (which is officially recorded, and as an end to the Kola). Here are some of the workers claimed that some of the wells were heard the sounds of hell sounds, and an explosion of it flew a "demon." Here's what he said officially about this Academy, David Huberman, who led the drilling throughout its existence: "When I was about this mysterious stories began to ask to UNESCO, I do not know what to say. On the one hand, bullshit. On the other - I, as an honest scientist could not say that I know what exactly happened with us. Was recorded very strange noise, then there was an explosion ... After a few days is nothing at the same depth was not found. " This sound is still present as recording microphone lowered into the well, but their authenticity is neither confirm nor deny not yet managed to anyone. Although it is doubtful that a microphone could withstand thermal stress at great depths.
