In a 2009 paper titled ‘Tunguska-1908 and similar events in light of the New Explosive Cosmogony of minor bodies’.
E. M. Drobyshevski predicted that some short period comets might be made of “ices consisting of H2O, primitive organics etc., with numerous mineral inclusions up to a few meters in size. And which are saturated in the form of a solid solution by products of their bulk electrolysis”.
That “bulk electrolysis” provides the potential for some interesting, and highly explosive, solid state chemistry. So we get the potential for pockets of 2H2+O2 concentrated to as much as 15 to 20% of the total weight of a fragment. And which makes them capable of detonation. Think of a Hydrogen-Peroxide bomb, or something like frozen rocket fuel
Drobyshevski’s hypothesis requires an electric current for that “bulk electrolysis” to happen. The electric field of a gas giant was the most obvious choice. So Drobyshevski favors a planetary origin of comets. He thinks of the origin of short period comets as being fragments of the explosively cast off outer shell of one of the icy moons of Jupiter, or Saturn. He thinks this has happened only 7 or 8 times in the history of the solar system.
Bill Napier was kind enough to explain for me that it simply isn’t possible to make a convincing astronomical model for a planetary origin for SP comets. But that Drobyshevski’s explosive chemistry hypothesis still works for an icy body from the Kuiper belt, or Oort cloud. Instead of the electric field of a gas giant, few billion years orbiting in the solar wind provides the long term current for bulk electrolysis of water ice.
Drobyshevski states that “It presently appears that it is these new concepts implying a possibility of a chemical explosion of ices of a cometary nucleus in the Earth’s atmosphere that provide the heretofore lacking link capable of solving the Tunguska phenomena problems.”
He may be right. I’ve collected a few hundred images of places in New Mexico, and West Texas that begin to make sense if some of the fragments are very highly explosive in their own right. Many of them are a perfect match for the kind of irregular, two-bowl craters Drobyshevski predicts.
I’ll let you be the judge. But the blast haloes, and ejecta patterns, of some of these things do seem to describe a very strange kind of explosive impact process. At the very least, they’re all interesting structures, and images.
The images were pretty much saved in the order they were found. So there is no particular order to them. But the scale, view height, and GPSs, are in the info bar at the bottom of each image. There are occasional duplicates here, and there. But as you view the galleries, a pattern begins to emerge. A set of common traits that can be found, no matter the location.
After studying the Tunguska event, I don’t have a problem with the idea of a comet fragment coming in at an oblique angle, and being able to shed almost all of its kinetic energy as heat in the atmosphere. Or with the idea of fragments surviving atmospheric entry, and slowing to subsonic speeds, and ‘dark flight’, only to explode like a powerful chemical bomb at, or near, the surface. My question for all, is in the nature, and cause, of the unusual, bi-lobed, and sometime 4 lobed, blast ‘patterns’.
