The facts about the Tunguska event

non-existent chunks of meteorites.

In the 1940's, E.L. Krinov, a Russian scientist who had once worked with Kulik, suggested that whatever had caused the 1908 Tunguska explosion had exploded in the air, leaving no crater. His theory was accepted and added to later by another Russian scientist, Aleksander Kazansev, a scientist who also examined the after-effects of the atomic bomb dropped on Hiroshima. Kazansev noticed that the Hiroshima bomb had exploded high in the air above the town, causing the trees directly below to become stripped of their branches, resembling poles, while flattening trees and houses in a pattern outward from the center of the explosion. This matched what had happened in Tunguska. At Hiroshima, there was also black rain after the blast, as well as a mushroom cloud, which eyewitnesses to the Tunguska incident had also reported. Scientists began to wonder if the Tunguska explosion had been caused by anti-matter or a mini black hole, while Kazansev wondered if an alien atomic powered spaceship had exploded.

Other similarities were noted between what had happened after the atomic explosion in Hiroshima and what had happened after the explosion in 1908 near the Stony Tunguska River. Reindeer in that Siberian region developed skin diseases similar to the Hiroshima human victims. Both areas experienced accelerated plant growth, in Tunguska, not only where the explosion occurred, but over the course of the area the object had passed over before exploding. In Tunguska, ant populations, seeds and needle clusters of pines showed genetic variations. The Evenks had developed unusual variations in their Rh blood factor.

Others took up the investigation. In the 1960's, it was noticed that there were actually four smaller centers within the larger oval, which might have corresponded with the sound of thunderclaps that had been heard in 1908, or, as they thought, separate and individual explosions. Each one of these smaller centers had its own pattern of fallen trees.

A group of Italian scientists analyzed resin from the fallen trees and found traces of matter embedded in the trees, particles of calcium, iron-nickel, silicates, cobalt-wolfram and lead. As these particles can also be found in cosmic matte, the question was once again raised as to why no pieces of meteorite, or even an asteroid, had been found. Peat bog samples, containing a layer from 1908, were found to have particles that had the potential to be explosive, and which resembled particles
