Over a century ago, on June 30th, 1908 a huge explosion detonated over an unpopulated region of Russia called Tunguska. It is probably one of the most enduring mysteries of this planet. What could cause such a huge explosion in the atmosphere, with the energy of a thousand Hiroshima atomic bombs, flattening a forest the [...]

UT: Was the Tunguska Fireball a Comet Chemical Bomb? (http://www.universetoday.com/2009/03/27/was-the-tunguska-fireball-a-comet-chemical-bomb/):


Sounds reasonable so far, but how did the fragment explode? Using our new understanding as to what chemicals comets contain, Drobyshevski surmises the fragment was rich in hydrogen peroxide.

Separated at birth?

Why couldn't it have been a steam explosion? The results looked very similar to the side blast from the steam explosion of Mt St Helens.

Right track, wrong chemical? I don't see how/why H2O2 would be trapped in a comet body - it is so unstable, but more stable hydrocarbons - like propane, acetylene, or similar to what is found on Titan, could be trapped in a rather hard body and released into the atomsphere as they ignite: a massive air-fuel bomb.

Bah! Humbug!! No one has been able to explain how heat can be conducted into the interior of the object that is evaporating, sublimating, and ablating to cause such an explosion. Oxidation of the material being sluffed off would represent as a stream of fire over tens of miles not a single explosion.

According to a recent documentary--isn't that what the Evnki (sic) saw? A column of fire? A hard nucleus caused the boom.

How is this for a possibility. The initial heating evaporates surficial ice and bakes the remaing mud into a bricklike material. With continued heating the bricklike crust would become thicker and thicker and confining the internal moisture. The internal moisture continues to heat and build up pressure that is finally released in a gigantic explosion.

The outer few millimeters would heat sufficiently to expel the mud before it baked or it would flake/break off as dust.

I thought this was already a confirmed alien space ship landing/crashing/repair facility.

Maybe it was man made, the detonation of a doomsday bomb in the future so big that all the energy could not be contained in that time so that part of it had to go back to 1908.

And as they stated in the comments section, "Nobody saw the comet enter or leave the area?" no tail, no debris trail?

I'll disagree with this "guess". I've read expedition notes that state that metal fragments were indeed found near the epicenter, embedded in trees and such. How much metal does your average comet contain?
