Biggest explosion in documented history is STILL a mystery: New study fails to find cause of 1908 Tunguska blast that 'split the sky in two' and flattened 80 million Siberian trees

This article is as fanciful as "project fear"

ISIS did it.

"Hold the front page!" Something weird just happened, over a hundred years ago....

...........frAcking

It was the Lord Almighty cursing us for our sinful ways! Read Revelation!

It is not the biggest explosion in documented history, we have recorded numerous supernovae. Lucky none were near enough to end all future earth history........not yet anyway.

I thought the place was radioactive.

As the area is a giant swamp, has anybody considered the possibility that this was a huge release of, and ignition of swamp gas?

I thought this was a North Korean A-bomb test?

Comets are made of rock, not ice. A comet's tail and coma don't come from ice melting in the sun; they are an electrical discharge phenomenon. As a comet traverses the sun's electrical field during its eccentric orbit, it builds up a potential difference with respect to it's environment which prompts the comet to emit ions in an attempt to equalize charge. If the comet passes close to a planet/moon it gets the chance to equalize charge with that body in a single instantaeous electrical discharge; a lightning strike more powerful than anything a cloud can produce, powerful enough to produce an airburst. That's what happened at Tunguska.

The great unwashed teenagers thought Brexit was on the cards........

Tesla energy beam from the USA bounced off the firmament and caused huges blocks of ice to fall to the earth

"Biggest explosion in documented history is STILL a mystery". No it isn't. It was definitely caused my the curry I had last night.

A very small particle of anti matter entering your atmosphere would have caused a matter / anti matter reaction creating an incredible amount of energy as evidenced by the destruction. Anti matter reacting with matter cancel each other out hence no crater or residue whatsoever. Anti matter is known to exist, ask the large Hadron collider people and hope they don't bring any into any uncontrolled existence. Starships are powered by warp engines which rely on a form of slowed down matter / anti matter reaction much like your simple nuclear reactor is a controlled form of a nuclear bomb. I'm surprised no one else has mentioned anti matter ! !

I11uminati experiment, clearly.

No mention of Tesla in the probable causes...hmm.

This happened because we attached Jeremy Corbyn to the top of a missile and fired it at Russia, all his hot air about nuclear weapons and why he should stay on as Labor leader resulted in this happening.

Putins bank statement

If they failed to find an explanation why run an article on it?

I've always been led to believe these kinds of events only happen in N. America & Hollywood.
