 THEORY ABOUT A PAST EVENT

At 7:17 AM on the morning of June 30, 1908, a mysterious explosion occurred in the skies over Siberia. It was caused by the impact and breakup of a large meteorite, at an altitude roughly six kilometers in the atmosphere. Realistic pictures of the event are unavailable. However, Russian scientists collected eyewitness accounts of the event. I believe that we now know enough about large impacts to "decode" the subjective descriptions of the witnesses and create realistic views of this historic asteroid impact as seen from different distances.

Questions:
Why was the explosion in Tunguska an extraordinary event?
Because it was about 1,000 times more powerful than the atomic bomb dropped on Hiroshima, Japan
Because there were fireworks in Hiroshima, Japan
The blast was something of the order of 50 Megatones of equivalent energy

Why did researchers visit the region 20 years later?
Because GPS techology was not available back then
Because radiation made it difficult for reasearchers to get close to the area
Because of the remoteness of the Tunguska region

When did the first expedition Tunguska got to the area?
In 1927
In 1987
In 1937

What was first thought about the cause of the explosion?
A small black hole passing through the Earth could have caused the blast
A meteorite may have caused the massive explosion
The annihilation of a chunk of antimatter falling from space might have caused the explosion

What is one example provided in the video about the radiation damage that took place in the area?
Humans suffering some gene damage
Strong tremors observed in the area
Unusual atmospheric events recorded on video camera

What did Kozintsev realize?
That the Tunguska region was remote
That a small black hole passing through the Earth could have caused the blast
The explosion patterns in both Hiroshima and Tunguska were quite similar

What conclusion did Kozintsev arrive to?
The explosion had to have been caused by the crash of a nuclear power alien spacecraft
A small black hole passing through the Earth must have caused the blast
Radiation made it difficult for researchers to get close to the area

What is true about the explosion in Tunguska?
Radiation made it difficult for researchers to get close to the area
Up to these days scientific explanations do not satisfy ufologists
The mystery can easily be explained by scientists
