This is concerning the various theories surrounding the Tungus region in Siberia, 1908.

I remembered reading about this awhile back on a few Universe Mystery type books/boards/papers ... apparently there are multiple theories about what happened in Siberia that destroyed a radius of 20 miles and was experienced 400 miles away. The most common is a meteorite. The problem with this theory was that they couldn’t find an actual impact crater.

Of course then we have the other theories that vary between crashed U.F.O to an advanced culture setting off a mid-air nuclear explosion. The evidence to show the mid-air explosion theory was the way the tops of the trees and land exposed to the sky were seared and the how the magnetism of the earth, at the time, showed a fluctuation that almost parallels the effect of a atomic-bomb.

They also proposed that the area may have been struck by a comet.
The comet theory also included that from the heat of atmosphere entry caused the dirty snowball head of the comet to explode. They say that from this explosion the dust and gases tossed into the air would account for the pale haze that hung over Europe for a few days.

One of the "odder" theories, was proposed in 1965, was that it might have been ""rock"" of anti-matter that was annihilated on contact with atoms of ordinary matter, producing a fire ball of gamma rays and the explosion. They this would explain the "flash burns," the lack of a mushroom cloud, and the lack of any residual material. Willard Libby favored this theory. He stated that only a small amount of anti-matter would be needed to produce a blast the same size (think it was like 20-25 millions tons of TNT). He also added that the disintegration of the rock would explain the brief increase of C14 in the atmosphere.

**Note: there was an increase of trees in L.A. and Vegas that showed an increase of C14 in 1909, but it was no where near the expected level of C14 that would be caused by an anti-matter object**

Both this theory and the others used the actually "fireball" that was witnessed by people as evidence to back up their theories.

Here, the next one, it’s my favorite, though it is the hardest to actually grasp as fact.

It has been suggested (sometime in the early 70's, that what might have caused the destruction in Tungus, might be a "mini black hole" passed through the earth and emerged in Siberia.

Now I’m not to up on blackhole science, I was just curious if this theory of a mini blackhole (star, matter etc) is feasible. Could earth /planet, be struck by a rogue mini blackhole? I do know Hawking researched the ideas of mini blackholes being created at the time of the Big Bang, from compression and areas of expansion.

Now there was an edition of "Nature" that was published with the scientists that originally proposed the blackhole theory but I can't remember the names for sure (...think one was something Jackson), that claimed a blackhole would account for the reports effects in Siberia. But wouldn't there need to be a place with the same type of destruction on the opposite of transition through the planet?

I will have to find more info on this subject. Would be interesting to hear from anyone else if they have run into this. Just thought they were interesting ideas, and read something about blackholes today on the boards that made me think about this.

**edited for spelling, one of these days I will get a handle on the English Language**

I once read it was Tesla playing with a really big coil. I wasn't very educated when I read it, so I don't know if the theory had back-up. Has anyone else heard this idea?

I've heard it but I don't think it's true. The generally accepted explanation is that a meteor exploded over the forest.

Telsa weapon if it worked could only go 500 mile max beacuse he could not of been able to curve it around the globe. Some say he would of been able to bounce it off the atmosphere but I do not think this.

Tesla was a nut. He tried to transfer electricity from one HUGE coil to another HUGE coil but miscalculated and blew up a barn in between...

Tesla was a genius and a nut, he want to send electrical power through the air to all homes without wires. Think about a gazillion watts going through the air all the time, what if something went wrong our beloved Canadian National tower could be leveled to the size of the Space Needle

hmm never actually researched much of the Tesla Weapon had it filed away with the Phila. experiment and other such ideas. Seems interesting enough. I just found it an interesting thought, rogue miniature blackholes causing destruction. Wasn't sure how much water this theory would hold.

Tesla didn't have black holes. He could just take massive amounts of electricity, point it at something and let her rip!

Don't forget that Tesla's idea of transmitting electricity through the air was put to excellent use in the second G.I. Joe movie. Remember the Broadcast Energy Transmitter? Maybe that belongs in the Bad movies section...

I brought this subject up over at the Straight Dope board last January. At least, the Tesla part. One of the posts mentions an article in a Russian magazine in the sixties that reported that aliens near Cynus 61 had received a signal from the Krakatoa eruption, and sent back a powerful beam, causing the Tunguska explosion.

The end of February, Cecil himself answered the question: What caused the massive 1908 explosion in Tunguska, Siberia? The black hole hypothesis is said to be dismissed as "hopelessly naive."

I would sure hope so! I'm still trying to figure this "mini black hole" thing.

lol nebularion ....me to. It's an interesting concept....I find it feasible...at the dawn or re-dawn of time.....but I couldn't it grasp it.....to the point where mind blackholes hitting planets. Why I was curious.

As for G.I. Joe 2 ....never saw it. The first one i like....still have it on beta...bata sp? lol. I liked when cobra commander turned into a snake....think that was that movie **scratches head**.

Miniature black holes are a possibility. They couldn't form in the normal way. through supernovae explosions, of course, but it's theorized that just after the big bang, the heat and density could have been enough to create black holes of less than stellar masses. Most of these primordial singularities would have been only a few grams in mass and would have long since evaporated away by now, but a few of the larger ones might have survived to the present day and could be drifting around the universe.

If one of these microscopic singularites passed through the Earth at high speeds, there would probably be massive shock explosions at the entrance and exit points. That's what some think the Siberian explosion was. The exit point would have been somewhere in the ocean and thus gone unnoticed in 1908.

It's a longshot theory depending on a lot of unproven assumptions, but it isn't exactly woo-woo stuff like the Tesla thing is.

I remember watching a show a couple of years ago where they were studying it. This guy set up a scale model of the forest and terrain and stuff, complete with trees that can be blown over, etc.

He then simulated different things, including an exploding meteor, to account for the nature of the destruction. What he found was that a meteor coming in at a fairly low angle and exploding at a height of, i believe, two miles would perfectly account for what happened. Sorry, I've no idea of the name or anything. I believe it was on Discovery.

That was the first movie. I have it on DVD. :-)

Well unless you are talking about the mini-series that happened during the regular show running.

I've heard of some meteors that vaporize over the site due to air friction but I always thought they left markings of there passage. hmmm :-?

If I remember correctly one of the episodes of Arthur C. Clarke's Mysterious World (1980) featured this simulation.

Tow main things to recall about this particular event.

1/ If any crater was formed it was buried deep in a swamp.

2/ The first scientists to the area took some twenty years to get there. So any real evidence has had a long time to degrade

it isn't unusal for meteors to explode mid air. It is a little unusual (In human experience anyway) for one so large to do it. This is one of the reasons I've been a bit of a comet fan as an explanation.

Glen

A comet would be the best candidate. Air burst as the first manifestastion. A comet would leave no record because it was small. A Known impact crater would have been detected. Know levels of Iridium for the region, even in 1927 ensured that the blast was not a solid, primordal mass. A diffuse energy source can expain what happened. no big deal. Big snowball does great things.,

Another explanation of the Tunguska event has been published, which may be better than the comet one (Wolfgang Kundt, Current Science, v. 81, n. 4, 399-407, 2001). Kundt argues that the event was caused by the volcanic ejection of "some 10 Mt of natural gas". He thinks the event was a modern-day formation of a kimberlite.

There is a lot of historical detail in the paper, and he uses this to support his argument. For example, one of the first scientists into the area was Leonid Kulik, who was also hoping to find meteoric nickel and iron. His team drained the 'Suslov' crater lake, only to find an intact tree stump at the bottom. This ruled out an impactor, since the stump should have been destroyed. There are other bits of evidence like this one. For example, he says the 'mystery clouds' seen after the explosion may have been rising blobs of natural gas.

He writes: "A kimberlite interpretation of the Tunguska catastrophe is tempting. ... kimberlite diatremes are narrow funnels, growing from a few metres across at a kilometre's depth to a dome-shaped tuff ring at the top, of diameter some kilometre, and occasionally enclosing a crater lake (reminiscent of the cauldron). ... An explosive injection from great depth is indicated, driven by volatiles".

The article is pretty interesting. There is a detailed map of the site at the time of the event, complete with the positions of various observers (and their fates!)

I only said the part about the slow venting of gas. I never tried to join your post. I have know idea how this happened.

I am sorry ExpErdMann. I have no idea what I did wrong! I thought that I was a computer nerdless. But I managed to do something I thought was impossile.

No problem. It took me a while to figure out what you were talking about, then I noticed your comment within the quote. You can edit your posts. The quotes are tricky and when using quotes it is a good idea to "preview" your post before sending it.

In the article there is a long calculation about the energy release, which I haven't really tried to grapple with. But he figures there's enough.

Thank you for being so forgiving sir. However. Impulse is impulse. The impulse in 1908 was a high impulse transaction of energy. Any release of energy from inside of the planet would have beeen low impulse because the damage observed in latter years indicated this not to be so. The vaste amout of energy points to a small amount of energy quickly expelled.

Kundt's mechanism is a fast impulse mechanism. According to Kundt, the gas being expelled from the kimberlite-type "nozzle" could reach velocities of more than 1,000 m/sec. It is an explosive event.

Tesla had also worked on a sending electrical impulses through the center of the earth. As the relatively weak electrical current reflected off the other side of the earth, it was amplified with the addition of another small bit of electrical energy. After awhile, the current was enough to cause electrical disruptions on the other side of the Earth. There was speculation at the time that he was working on military applications, such as being able to cause EMF interference with circuitry on the other side of the planet. If I am not mistaken, this is what the large facility at Wardenclyffe was built for. (Un)foutunately(?) Tesla dismanteled it before it was finished because he felt that it would be extremely dangerous in the hands of a military force.

Although the jury is out on if this could have caused the phenomenon at Tunguska, it certainly shows that at least SOME of Tesla's experiments had a longer range than 500 miles. Apparently he also sent a telegram to Commander Perry, the first North Pole explorer as Perry was making his historic expedition. The telegram told him to look for something on the night that the Tunguska explosion occurred. He was apparently aiming an enormous amount of energy up towards the north pole for Perry to see. Some theories state that the target area was overshot and hit Tunguska instead. Definately an interesting concept at the very least.

Here is a site that talks about it in some detail:
http://www.frank.germano.com/tunguska.htm#N_37_

Even at a high velocity, as stated above, there would not be enough ergs to flatten the forrest that was seen. There seems not to be some kind off global result but a fierce bang in London. Also, was the hole 50 metres,1000metres. Again, Is there evidence for this outgassing source? At the before ammentioned velocity, the vent hole would make a huge difference.

Hello Bollzmann. Tesla stuff. Is it for real or not? If this kind of tech had been demonstrated back in the good old days. Be asurred that we would be using this tech today. As towards the concept that Tesla's stuff had a range greater than 500 miles begs the question as to whether the devise fired period!
