- A very powerful blast took place 94 years ago 70 kilometers
far from the settlement of Vanavara in Russiaís Siberian republic
of Evenkiya. The power of the explosion was equal to two thousand explosions
of Hiroshima A-bomb.
-
- A huge meteorite flew over the vast territory of West
Siberia on June 30, 1908 at 7:15 a.m. The people, who could see the meteorite
in cloudless sky, were horrified with its bright light and rattling sounds.
People said that they could see a big ball of fire flying eastwards and
falling in the woods. When scientists evinced their interest in the meteorite,
they calculated the damage of the Earth ñ 2000 square kilometers.
The blast of the year 1908 changed the magnetic field of the Earth: the
magnetic storm, which was registered on the outskirts of the Russian city
of Irkutsk, lasted for 3.5 hours.
-
- Strange consequences of the collision continued 15-20
hours after the catastrophe: unusual luminescence of the atmosphere and
noctilucent clouds were registered on the territory, which totaled 12 million
square kilometers. The radiance of the sky was so bright, that people could
not fall asleep ñ the light was so bright that you could easily
read a newspaper at night.
-
- Thousands of square kilometers of woods were burnt. Scientists
have had a lot of talks, trying to find out the reason of the phenomenon
in Siberia. The major version was about the collision of the Earth with
a comet or an asteroid, but none of countless expeditions found either
a crater, or some fragments of a space object. This gave birth to a lot
of unusual hypotheses: someone said that it was connected with aliens,
others said that the Earth collided with a black hole. For the time being
there are more than a hundred of hypotheses, explaining the reason of the
super-blast: they vary from the explosion of marsh gas (methane) to a spaceship
catastrophe.
-
- The epicenter of the explosion is still preserved: thousands
of trees, lying on the ground with their roots to the center. There is
the Tunguska state reserve on that site currently, which gathers scientists
(and even tourists) from all over the world. Other hypotheses supposed
that the Tunguska meteorite was made of the anti-substance. The blast that
could be seen and heard, when the meteorite fell down, was the result of
the collision of the substance of the Earth and the anti-substance of the
meteorite. But the radioactivity is normal in the area of the fall, there
are no radioactive elements in the rocks, so a nuclear explosion could
not take place there. It was also supposed that the Tunguska meteorite
was a micro-black hole, which entered the Earth in the area of the fall,
ran through the planet and went out in the Atlantic ocean. This hypothesis
also has its contradictions, like the issue of micro-black holes existence,
luminescence of atmosphere, etc. Italian scientists said that they found
the right answer: they said that an asteroid of low density blew up in
the atmosphere of the Earth.
-
- The Tunguska meteorite was apparently similar to Matilda
asteroid, which was photographed by NEAR-Shoemaker spacecraft in 1997.
Matildaís density was close to water. Such an object could explode
and fall to little pieces in the atmosphere, but the air-blast could reach
the Earth, which explained the absence of fragments.
