Tunguska catastrophe of 1908, the causes of which are not fully unraveled until now, there was an explosion due to hydrogen-saturated part of the nucleus of a comet, with most of the comet's nucleus survived and perhaps continues to revolve around the sun, says astronomer Edward Drobyshevskiy Petersburg.
In the Stony Tunguska River basin in what is now Evenk, June 30, 1908 and flown by the fireball exploded. The expedition, to get to the disaster area in 1927, found fallen timber on an area roughly equal to modern Moscow. However, at the site of the explosion has not been found traces of the fall, nor the wreckage of the cosmic body. Hypotheses put forward about a hundred — from an alien spaceship to blast detonation vyrvashegosya of tectonic fractures of natural gas.
Doctor of Physical and Mathematical Sciences Edward Drobyshevskiy, Chief Scientific Officer Physico-Technical Institute of the Russian Academy of Sciences Joffe believes that the Tunguska catastrophe can be explained in the framework of his theory of the origin of short-period comets.
According to this theory, the nuclei of comets are formed in the explosions icy shells of celestial bodies like Jupiter's satellites Callisto and Ganymede. In ice shells, according Drobyshevsky under the influence of a powerful magnetic field of Jupiter there are strong currents and is in the process of electrolysis of ice — it accumulated hydrogen and oxygen, which eventually explode. Ice Shards and become the nuclei of comets, says the scientist.
Callisto shell explosion, inevitable in its opinion in the future may lead to the emergence of many such comets, and to the loss of "rain" of ice debris on the surface of the Earth, which could lead to the death of civilization.
In an article posted in the digital library at Cornell University, the scientist says that the key characteristics of the Tunguska catastrophe can be easily explained within the framework of his theory.
According to him, in 1908, into the Earth's atmosphere tangentially became icy comet nucleus, rich in dissolved hydrogen and oxygen. The speed of the body was about 20 kilometers per second, the size of 200 to 500 meters, and weight — 5 to 50 million tons. Part of the core mass of about a million tons detonated at high altitude, and the explosion created a characteristic pattern of tree fall on the ground and other phenomena.
"The main part of the core passed through the earth's atmosphere and out into space. This body is now moving in an orbit a short-period comets, and may eventually be identified, "- says the scientist, claiming at the same time that the fall of the nucleus of a comet to Earth would create a crater with a diameter of 3.5 to 8 kilometers, and release dust, which could lead to a climate catastrophe.
E.Drobyshevsky for years develops a theory, which he called the "New explosive cosmology." However, many scientists believe it is too exotic — in their opinion, the observed facts can be explained without resorting to this hypothesis. However, to refute the theory of explosions ice shells no one has, as scientists have not yet managed to get samples of cometary material.
