Russian Scientists Search for 'Cosmic Matter' Near Site of Tunguska Blast



Scientists in Russia are studying sediment from a Siberian lake in the hope of finding 'cosmic matter' which will confirm that the Tunguska explosion was caused by a meteor entering Earth's atmosphere. While this hypothesis for the mysterious 1908 event, which saw an enormous blast flatten 80 million trees over an area of 830 square miles, has already been largely accepted by the scientific community, it remains unproven. Over the years, some rogue researchers have put forward alternative possibilities for what could have been behind the incident, including the fantastic suggestion that Nikola Tesla was somehow to blame for the event.

Now a new expedition reportedly featuring experts from four scientific organizations in Russia looks to put an end to the speculation. "The mystery of the Tunguska Catastrophe worries both the scientists and the public," said Dr. Arthur Meidus, one of the researchers working on the project, "many of us still hope to unravel the scenario of 1908 disaster." The focus of the study centers around sediment found at the depths of a remote lake located approximately 25 miles from what is believed to have been the epicenter of the blast. "Spring-autumn wastewaters and the Lakura River brought traces of the Tunguska catastrophe to this lake," Meidus explained.

By determining which layer of sediment can be connected to the time frame of the Tunguska blast, the researchers hope to examine this material using what are described as "modern methods of microanalysis" using advanced scientific techniques. If the explosion were truly caused by a meteor entering the Earth's atmosphere, they say, then the study should find "microparticles of extraterrestrial origin" in the sand extracted from the lake. Such a discovery, the research team contends, would finally close the case once and for all. One can only hope that this attempt at solving a decades-old Russian mystery goes better than the reopened Dyatlov Pass investigation from last year that we're still waiting to be resolved.

Bold New Theory Offered for Source of Tunguska Blast

An intriguing new theory has been offered for what caused the legendary 1908 Tunguska event. Scientists studying the strange incident, in which a mysterious blast of some kind flattened a whopping 80 million trees over an area of 830 square miles in Siberia, have long suspected that it was caused by a meteor striking the Earth. However, a recently published paper reportedly calls that hypothesis into question and, instead, put forward a rather fantastic alternative explanation.

Siberian scientists studying the case argue that the Tunguska event was actually the result of a sizeable iron asteroid entering the Earth's atmosphere, skimming the planet, and then shooting back out into space. The bold idea was based on mathematical models which explored different scenarios wherein asteroids of varying size, composition, and trajectory interacted with the Earth. Through this process, researchers were able to rule out an icy ball and a rocky object as the culprits for the blast and, in turn, determined that it was most likely an iron asteroid.

The model which best matched what occurred in 1908 indicated that the iron interloper was approximately 320 to 650 feet in diameter and zipped across 1,800 miles of the Earth's atmosphere before exiting back into space. This brief moment, researchers say, would generate the force seen on the ground in Tunguska and explain why there is no crater that can be connected with the event. The scientists behind the paper also noted that the theory accounts for "optical effects associated with a strong dustiness of high layers of the atmosphere over Europe, which caused a bright glow of the night sky."

An interesting idea...….but much of the evidence indicates an airburst similar to the one in Chelubynsk in 2013.

Yes, imo the Tunguska event is certainly 'required-reading' for any young student of the anomalistc and paranormal as many of us were.
I as you can probably guess, first began to become engrossed in the incident at an early age in view that it was widely touted as being the product of a 'crashed flying saucer', which was a prospect that initially excited my curiosity as from time to time I came upon articles that claimed that there was eye-witness testimony of the actual 'object' changing direction before crashing. … ergo intelligently controlled! … But unlike the sensation seeking suppliers of such unsubstantiated tall-tales like that kind of claim I grew to require a much greater degree of reliable corroboration to accept this as any kind of evidence of anything really,... and after all these years I've not found any, and so declare B.S on that!
… I also declare a similar feeling about the 'Alien-Battlefield', the 'Secret Nuclear-testing', the 'Mini Black Hole', the Mysterious-manifestation of a clump of Anti-matter', and especially the nutty 'Nicola Tesla Energy Weapon' theories!
… And though I claim to be no expert at all in these matters, I would be prepared to throw my hat into the far more sensible [and imho likely] Airburst Theory, that has been proposed and soberly explained in recent years. [ as mentioned by Nivek above. :Thumbsup: ]

.. but the more exciting and even romantic notions of alien altruism etc from the likes of Asimov et al will always have a place in my heart .. if not reasoning when thinking about Tunguska . lol.
...It did enormous damage (Siberian Explosion), for it fell in a forest and knocked down every tree for scores of miles in every direction...if that fall had taken place anywhere in the ocean, tsunamis (tidal waves) would have washed nearer shores and done much damage...if the fall would have taken place there (permanent ice), cause slippage of large quantities of ice into the ocean, bringing about catastrophic changes in Earth's sea level and climate...if the fall had taken place there (populated areas)...millions of people would have been killed...The fall would have completely wiped out any city it struck. Perhaps not more than 5% of the surface of the Earth could have received that 1908 blow without any damage at all being done to human life and property...consider that the fall managed to find a 1 in 20 place where it would do no damage, almost as though someone was humanely trying to avoid...'- Isaac Asimov

Cheers.

I have to admit this hypothesis never occurred to me, it was a huge explosion obviously, yes a nuke type explosion could have caused it, but still, a meteor explosion could have also caused that explosion and subsequent damage...I didn't know there were eyewitness reports of course corrections of the object before it exploded, I wish there were more details because if they were minor corrections it still could have been a meteor hitting the denser part of our atmosphere and shifting around under the stresses before exploding...Nice theory and its possible, we need more data, maybe there are UFO fragments still in the area...I don't know how well those metamaterials hold up under huge stresses like that one...

Great find 1963! I like this theory...

Yes my old friend, I too favour the 'airburst' explanation, but have read about these witness accounts that claim that 'the object' changed course several times ... [and not just slightly] on many occasions ...

(DOC) The Tunguska Event, 1908: Actually, It Was a UFO | Timothy G Chilman - Academia.edu
... but then the fact that it was so long ago and in so much of a unfamiliar country , makes this fact hard to be certain about. .. And the 'airburst theory' does seem to be the choice candidate of many of the more 'open-minded' analysts.
... But yes! ... I set off learning about this old case many years ago on the old 'Arthur C Clarke' programme [c.1979-ish] and being impressed that it may indeed have been a 'crashed UFO' ... and though i'm no longer swayed to that position, ... I haven't totally written the possibilities off! ;)

Cheers Buddy.

... Although there were another factor that has to be dismissed in order for the object to have been a meteorite ... namely the eyewitness testimony that stated that the object was 'cylindrical' ["pipe", i.e., a cylinder.] and that the witnesses ...[ just described as a Karelinski village of peasants in the newspaper] testified that they watched 'the cylindrical object "moved downwards for 10 minutes"! ... 10 minutes?? ... meteors according to internet data travel somewhere between 25,000 and 160,000 kph ... and that surely doesn't add up in anyone's mind does it.!? ... 10 minutes at the lowest speed means that they watched the object travel 4166 miles and at the higher speed it would be 26,666 miles ... or any distance between the two.....
Sibir newspaper, 2 July 1908:
On the morning of 17th of June,[23] around 9:00, we observed an unusual natural occurrence. In the north Karelinski village [200 verst (213 km (132 mi)) north of Kirensk] the peasants saw to the northwest, rather high above the horizon, some strangely bright (impossible to look at) bluish-white heavenly body, which for 10 minutes moved downwards. The body appeared as a "pipe", i.e., a cylinder. The sky was cloudless, only a small dark cloud was observed in the general direction of the bright body. It was hot and dry. As the body neared the ground (forest), the bright body seemed to smudge, and then turned into a giant billow of black smoke, and a loud knocking (not thunder) was heard as if large stones were falling, or artillery was fired. All buildings shook. At the same time the cloud began emitting flames of uncertain shapes. All villagers were stricken with panic and took to the streets, women cried, thinking it was the end of the world. The author of these lines was meantime in the forest about 6 versts [6.4 km] north of Kirensk and heard to the north east some kind of artillery barrage, that repeated in intervals of 15 minutes at least 10 times. In Kirensk in a few buildings in the walls facing north-east window glass shook.

Cheers Buddy .

I must admit I haven't dug too deep into this event before, just in passing and accepted the meteor explosion explanation without looking into other possible causes...Yes this happened a long time ago and in a region remote in many ways from the rest of the world...My interest has been kindled with these recent posts of yours @1963 thanks, I'll be spending a little time doing more reading about this event, the UFO crash/explosion theory is fascinating...
