    On June 30, 1908, in a remote part of Russia, a fireball was seen streaking across the daytime sky. Within

    moments, something exploded in the atmosphere above Siberias Podkamennaya Tunguska River in what is

    now Krasnoyarsk Krai, Russia.

    This event now widely known as the Tunguska eventis believed to have been caused by an incoming

    meteor or comet, which never actually struck Earth but instead exploded in the atmosphere, causing what is

    known as an air burst, three to six miles (510 kilometers) above Earths surface.

    The explosion released enough energy to kill reindeer and flatten trees for many ki lometers around the blast

    site. But no crater was ever found.

    At the time, it was difficult to reach this remote part of Siberia. It wasnt until 1927 that Leonid Kulik led the

    first Soviet research expedition to investigate the Tunguska event. He made a initial trip to the region,

    interviewed local witnesses and explored the region where the trees had been felled. He became convinced

    that they were all turned with their roots to the center. He did not find any meteorite fragments, and he did

    not find a meteorite crater.

    Over the years, scientists and others concocted fabulous explanations for the Tunguska explosion. Some were

    pretty wild such as the encounter of Earth with an alien spacecraft, or a mini-black-hole, or a particle of

    antimatter.

    The truth is much more ordinary. In all likelihood, a small icy comet or stony asteroid collided with Earths

    atmosphere on June 30, 1908. If it were an asteroid, it might have been about a third as big as a football field

    moving at about 15 kilometers (10 miles) per second.

    Because the explosion took place so long ago, we might never know for certain whether it was an asteroid or

    comet. But in recent decades astronomers have come to take the possibility of comet and asteroid impacts

    more seriously. They now have regular observing programs to watch for Near-Earth Objects, as theyre called.

    They also meet regularly to discuss what might happen if we did find an object on a collision course with

    Earth.

    Bottom line: On June 30, 1908, an object from space apparently exploded in the atmosphere above Siberia.

    The explosion killed reindeer and flattened trees, in what has become known as the Tunguska event.

    Scientists calculated the Tunguska explosion could have been roughly as strong as 20 megatons of TNT, or

    roughly 1,000 times more powerful than the atomic bomb dropped on Hiroshima, Space.com reported.

    Mysterious Tunguska Explosion of 1908 in Siberia may be linked to Tesla's experiments of wireless

    transmission

    an electromagnetic field from the "Tesla Coil".

    Many theories have been proposed for the cause of the explosion. One theory is that Tesla'sexperiments with wireless transmission may have inadvertently caused the explosion.

    Did you know that in 1908 in Siberia, one of the most catastrophic, mind-blowing (and mysterious)

    cosmic impact catastrophes everin the history of civilization occurred - and yet it wasn't widely

    known outside Russia (save for a few astronomy and research scientist enclaves) until around the

    1970's? Even interested research parties didn't learn about or even set foot on the scene of disaster

    until 1921. It didn't make front page news in the papers when it happened because of the extreme

    remoteness of that region of Siberia. Also at play was the secretive, unsettled nature of Russia at the

    time (which of course only heightened the many conspiracy theories surrounding it today) (taken

    from articleThe Tunguska Explosion of 1908).

    The so-called Tunguska Event refers to a major explosion that occurred on 30 June 1908 in the

    Tunguska region of Siberia, causing the destruction of over 2000 km2 of taiga, globally detected

    pressure and seismic waves, and bright luminescence in the night skies of Europe and Central Asia,

    combined with other unusual phenomena. The Tunguska Event may be related to the impact with

    the Earth of a cosmic body that exploded about 510 km above ground, releasing in the atmosphere1015 Mton of energy. Fragments of the impacting body have never been found, and its nature (cometor asteroid) is still a matter of debate. (from the article "A possible impact crater for the 1908

    Tunguska Event")

    Tesla's Possible Connection to the Tunguska Explosion, Siberia, 1908

    One theory is that Tesla's experiments with wireless transmission may have inadvertently caused the

    explosion.

    "Nikola Tesla, was testing out some sort of weird, fantasmigorical communication device, or super-scary "energy weapon" or "death ray" and made a big "...oops!" Tesla was known to be working on a

    sort of wireless torpedo, called an "telautomaton," which was a remote controlled boat he offered to

    the U.S. Navy for the purpose of carrying explosives to naval targets. An airborne version of the

    telautomaton device was under development as well. Some also believe that if there was a Tesla

    connection, and it was a weapon test... that he may have been pressured into it and then kept quiet.

    This is of course just heaping extra drama onto a theory already wrought with ridiculousness. Even

    though the 1908 time frame does match up for Tesla working on such devices, for him to be testing

    out such inventions in such an apocalyptic manner is quite a stretch, not to mention he was nowhere

    near the area at the time. Even funnier: the theory that Tesla inadvertently caused the massive

    explosion when he was trying to get the attention of an explorer friend in the area. Tesla was always

    fascinated with the concept of wireless propagation, and he was known to work on "projected wave

    energy" processes that could create microscopic, invisible particles of concentrated energy that could

    be beamed great distances... often resulting in electric fireballs, spherical plasmoids, or ball lightning.Why not use it to get someone's attention who's not near a telegram service? Of course this falls into

    the "secret weapons test" category as well. The theory that he was using it to try and get the attention

    of a friend halfway around the world is hilarious, but adsurd: *K-A-B-O-O-O-M!!!* ---"Albert... this is

    Nikola, please call me." Here is alinkto some New York Timesarticles where Nikola speaks of such

    devices, which date from 1907, 1908 and 1915" (taken from

    "Tesla said his transmitter could produce 100 million volts of pressure and currents up to 1000

    amperes, with experimental power levels of billion or tens of billions of watts.(18)If that amount of

    power were released in "an incomparably small interval of time,"(19)the energy would be equal to the

    explosion of millions of tons of TNT, that is, a multi-megaton explosion. Such a transmitter would be

    capable of projecting the force of a nuclear warhead by radio. Any location in the world could be

    vaporized at the speed of light." (taken from Frank Germano at
