Aculina and Ivan, Russian peasants, one morning lived a terrifying experience. Ivan told the following: "The sky opened in two and was covered with fire, there was a roar, the horses tried to run, but fell to their knees, and I, I was thrown several meters from my cabin."
Aculina, his wife, clung to a wagon, watching as the fir trees of the forest folded and a hot wind ripped earth from the ground and raised walls of water in a nearby lake.
These witnesses were 45 kilometers from the explosion; the phenomenon was due to the destruction of a piece of comet, at the time of entering the earth's atmosphere. Everything happened in a large region of Russia called Tunguska, and generated so much dust in suspension in the atmosphere, that a few days later, its brightness allowed reading at night in a radius of 5 thousand kilometers.
This was a forgotten area of Russia by the forgetful government of the tsars, who never sent to investigate the facts. The first scientists arrived at the site many years later, with the first Bolshevik government and verified the destruction that, in thousands of square kilometers, had caused that 'small' piece of kite.
Today it is known that such colossal destruction was caused by a fragment no bigger than a soccer field and it is worth remembering that the orbit that the earth travels contains millions of fragments; yes fragments, ranging from a speck of dust, to a piece of iron or ice the size of a country.
The event of Tunguska, happened on a day like today, June 30, 1908, and reminds us that we, Earthlings, are sailing at high speeds in a piece of dreams, our home and ship.
