Great Mystery revealed: Tunguska Event, link with the Mythic Hyperborea or the Lost realm of Asgard, page 1

The peace of God to all that belong to the light,
Dear Readers,
Today in this first centenary of the most impressive event that the modern history ever register about the contact of our planet with other celestial bodies, the so called Tunguska event, let me recall some important statistics of this incredible phenomenon:
- Estimates of the energy released on the impact range from 5 megatons to 30 megatons of TNT, with 10–15 megatons the most likely
- This power was 1000 times as powerful as the bomb dropped on Hiroshima in 1945 and about a Third of the power of the Tsar Bomba, the largest nuclear weapon ever detonated.
- This explosion knocked over an estimated 80 million trees over 2,150 square kilometres (830 square miles).
- It is estimated that the earthquake from the blast would have measured 5.0 on the Richter scale.
- An explosion of this magnitude is capable of destroying a large metropolitan area like New York, Los Angeles, Paris, Shangai or Mexico of today.
- This possibility has helped to develop the important discussion of asteroid deflection strategies.
- An atmospheric shock wave circled the Earth twice. So , during the next two days , there was so much fine dust in the atmosphere that newspapers could be read at night by scattered light in the streets of London, at about 10,000 km (6,213 miles) from the site of the impact.

Let me finish this update recalling the important thoughts about it of one of the most important thinkers of the XX Century, the memorable physicist Carl Sagan, also Pulitzer and Priestley prize, that I am sure should have wanted to see this aniversary:

This remarkable occurrence is called the Tunguska Event.

Some scientists have suggested that it was caused by a piece of hurtling antimatter, annihilated on contact with the ordinary matter of the Earth, disappearing in a flash of gamma rays. But the absence of radioactivity at the impact site gives no support to this explanation.

Others postulate that a mini black hole passed through the Earth in Siberia and out the other side. But the records of atmospheric shock waves show no hint of an object booming out of the North Atlantic later that day.

Perhaps it was a spaceship of some unimaginably advanced extraterrestrial civilization in desperate mechanical trouble, crashing in a remote region of an obscure planet. But at the site of the impact there is no trace of such a ship.

Each of these ideas has been proposed, some of them more or less seriously. Not one of them is strongly supported by the evidence.

The key point of the Tunguska Event is that there was a tremendous explosion, a great shock wave, an enormous forest fire, and yet there is no impact crater at the site. There seems to be only one explanation consistent with all the facts: In 1908 a piece of a comet hit the Earth.

In the vast spaces between the planets there are many objects, some rocky, some metallic, some icy, some composed partly of organic molecules. They range from grains of dust to irregular blocks the size of the State of New York. And sometimes, by accident, there is a planet in the way. The Tunguska Event was probably caused by an icy cometary fragment about a hundred meters across-the size of a football field-weighing a million tons, moving at about 30 kilometers per second, 70,000 miles per hour.

If such an impact occurred today it might be mistaken, especially in the panic of the moment, for a nuclear explosion. The cometary impact and fireball would simulate all effects of a one megaton nuclear burst, including the mushroom cloud, with two exceptions: there would be no gamma radiation or radioactive fallout.

Could a rare but natural event, the impact of a sizable cometary fragment, trigger a nuclear war? A strange scenario: a small comet hits the Earth, as millions of them have, and the response of our civilization is promptly to self-destruct. It might be a good idea for us to understand comets and collisions and catastrophes a little better than we do.

Carl Sagan, from his book Cosmos, Heave and Hell

Thanks for your atention,

and thanks to Carl Sagan, where ever he is now, for his wise words and deep meditations, his spirit of search of Science and Peace, his outstanding geniality was a genuine shining Light in the middle of the darkness of a world permanently menaced by the spectrum of a nuclear Armageddon.

your friend,

The Angel of lightness
