At 7:17am, local time on June 30th, 1908 at Tunguska, north east of Lake Baikal in Russia, a huge explosion occurred. This explosion was equal to about 1000 times that of the bomb dropped on Hiroshima.
This explosion caused all trees in a 20 mile radius to blow down and the flash could be seen 250 miles away.
Many have speculated as to the cause of this explosion. Most consider it to be caused by a Meteorite or Comet. There was no crater and so they speculate that as it heated up in our atmosphere, it became so hot that it exploded, perhaps 2 or 3 miles above the surface of the Earth.
Others have speculated that it could have been caused by a small Black Hole that passed through the Earth.
The trouble with these theories is that they cannot explain everything about the incident.
If a Black Hole had passed through the Earth, there should have been an exit point somewhere in the North Atlantic. Although reports of any unusual occurrences were thoroughly looked for, for that time, none were found.
Neither theory explains green globules that were found at the sight. These green globules were melted metal. After examination, the metals were found to be of types that were not found in that area, neither were they of a type believed to be part of the make up of asteroids.
Also there was a disturbance in the Earth’s magnetic field at the time of the explosion. Neither theory would account for this but an atomic explosion would.
An Australian journalist John Baxter and an American scholar Thomas Atkins studied the reports of the Russian scientists and collected eye witness reports.
They published their findings in a book “The Fire Came By” in 1976.
Their book says they found substantial evidence indicating this was some kind of atomic blast.
Their theory is that perhaps an Alien spacecraft was the cause. They consider the possibility that an Alien craft intended to land on Earth, however during their entry into our atmosphere, they had some kind of power disruption. This disruption caused a nuclear component in the spacecraft to explode about 2 miles above the surface of the Earth.
They claim that the green globules could be melted metals from the spacecraft.
This theory, however bizarre, would seem to account for all aspects of the explosion, especially since, more recently; mutations found in trees around the site seem to match those found in trees around Hiroshima.
