New evidence supporting theory of extraterrestrial impact found

An 18-member international team of researchers that includes James Kennett, professor of earth science at UC Santa Barbara, has discovered melt-glass material in a thin layer of sedimentary rock in Pennsylvania, South Carolina, and Syria. According to the researchers, the material –– which dates back nearly 13,000 years –– was formed at temperatures of 1,700 to 2,200 degrees Celsius (3,100 to 3,600 degrees Fahrenheit), and is the result of a cosmic body impacting Earth.

These new data are the latest to strongly support the controversial Younger Dryas Boundary (YDB) hypothesis, which proposes that a occurred 12,900 years ago at the onset of an unusual cold climatic period called the Younger Dryas. This episode occurred at or close to the time of major extinction of the North American megafauna, including mammoths and giant ground sloths; and the disappearance of the prehistoric and widely distributed Clovis culture. The researchers' findings appear today in the Proceedings of the National Academy of Sciences.

"These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO's)," said H. Richard Lane, program director of National Science Foundation's Division of , which funded the research. "SLO's are indicative of high-energy cosmic airbursts/impacts, bolstering the contention that these events induced the beginning of the Younger Dryas. That time was a major departure in biotic, human and climate history."

Morphological and geochemical evidence of the melt-glass confirms that the material is not cosmic, volcanic, or of human-made origin. "The very high temperature melt-glass appears identical to that produced in known cosmic impact events such as Meteor Crater in Arizona, and the Australasian tektite field," said Kennett.

"The melt material also matches melt-glass produced by the Trinity nuclear airburst of 1945 in Socorro, New Mexico," he continued. "The extreme temperatures required are equal to those of an atomic bomb blast, high enough to make sand melt and boil."

These are photos of melt glass known as trinitite formed at the ground surface from the melting of sediments and rocks by the very high temperatures of the Trinity nuclear airburst in New Mexico in 1945. This material is very similar to the glassy melt materials now reported from the cosmic impact YDB layer, consistent with the very high temperature origin of the melt materials in the YDB layer.

The material evidence supporting the YDB cosmic impact hypothesis spans three continents, and covers nearly one-third of the planet, from California to Western Europe, and into the Middle East. The discovery extends the range of evidence into Germany and Syria, the easternmost site yet identified in the northern hemisphere. The researchers have yet to identify a limit to the debris field of the impact.

"Because these three sites in North America and the Middle East are separated by 1,000 to 10,000 kilometers, there were most likely three or more major impact/airburst epicenters for the YDB impact event, likely caused by a swarm of cosmic objects that were fragments of either a meteorite or comet," said Kennett.

The PNAS paper also presents examples of recent independent research that supports the YDB cosmic impact hypothesis, and supports two independent groups that found melt-glass in the YDB layers in Arizona and Venezuela. "The results strongly refute the assertion of some critics that 'no one can replicate' the YDB evidence, or that the materials simply fell from space non-catastrophically," Kennett noted.

He added that the archaeological site in Syria where the melt-glass material was found –– Abu Hureyra, in the Euphrates Valley –– is one of the few sites of its kind that record the transition from nomadic hunter-gatherers to farmer-hunters who live in permanent villages. "Archeologists and anthropologists consider this area the 'birthplace of agriculture,' which occurred close to 12,900 years ago," Kennett said.

"The presence of a thick charcoal layer in the ancient village in indicates a major fire associated with the melt-glass and impact spherules 12,900 years ago," he continued. "Evidence suggests that the effects on that settlement and its inhabitants would have been severe."

perhaps it is the wipeout of vast amounts of human beings at that time that made possible the explosion of a bottle neck population of humans that were peaceful and disposed enough to farm successfully over the span of many years, and that might explain the flowering of civilizations during this period, whereas before hand, the existing culture of humanity was more brutish and dominate by entirely violent nomadic tribes with little incentive to cultivate and store grain or other foods on any significant scale.

Observation of high-intensity plasma discharges on the Earth's surface cast doubt upon the principle of gradualism, aka uniformitarianism. Furthermore, Anthony Peratt has identified 85 classes of petroglyph archetypes which correspond to high-intensity laboratory plasma discharges -- strongly suggesting a cause for the anomalous similarities we observe in both petroglyph and mythological archetypes. The squatter man petroglyph archetype is particular convincing, as it is occasionally drawn with dots beneath the raised arms -- suggesting the location of high-intensity synchrotron radiation which would occur at that precise location, in the process of translating the 3-dimensional plasma discharge onto 2-dimensional rock art.

The existing gravitational scientific framework is likely not the proper context to perform this research. In order to study these new lines of investigation, we must look to the (largely abandoned) plasma-based cosmology advocated by Hannes Alfven.

Just one of these impacts pierced the North American continent at lower right hudson bay creating a 500 km wide bullet hole. The continent was cracked and rifted which seperated the two halves of the crater a great distance. Half the continent was smashed downward by the force and is still rising today, something "science" wishes you believe is isostatic rebound. Highly advanced civilizations were lost during this and the resultant pole shift.

I don't know who is more hilarious, the ever repeating James Kennett (who last presented a paper on this, as the critics say, externally unrepeatable hypothesis in March) or the ever repeating crackpots in the comments.

Ironically, two of the crackpots have posited this to have occurred on opposite sides of the globe.

This has never been a problem of evidence but of human psycology as on display here. Careful exam of hudson bay geology shows the half crater filled brim to brim with specific lava that filled initial hole. Nowhere else is this lava present except the long thin trail headed north at the rift line to where other half of crater moved and was disfigured.

The "absolute dating" from tree rings is still much of an inexact science. Here is the 1 article that purports a definitive timeline of 11,000 years, but it lacks any extensive corroboration.

Without this kind of corroboration, the "12,900 years ago" claim above is invalid.

There was a LOT going on about 10,900 BCE. The climate change in Egypt (the rain stopped), megafauna disappearing, Clovis culture (which looks strangely like Europe's Solutrean) disappeared, agriculture and year-round settlements appear, animals get domesticated, pictures evolve into pictographs...

Re: "The first 4 are extraordinary even for the normal gang of crazies on phys.org!"

I think it just goes to show that you are what you read.

People who refuse to read anything about mythology will not realize that the stories all talk about catastrophe.

People who refuse to read IEEE's Transactions on Plasma Sciences will fail to know anything about Anthony Peratt, or his work on petroglyphs.

People who refuse to read criticisms of conventional theory will not know that they exist at all.

People who refuse to read about plasma-based cosmology with the same due diligence that they learned about the conventional theories will tend to not know how plasmas behave in the laboratory.

People who don't know much about plasmas nor petroglyphs will fail to realize the similarities in the morphologies.

People who prefer to think that there are no mistakes in our theories will exclusively seek out stories which support that.

You might try actually learning about the mythological archetypes. There are unusual similarities in the stories of the cultures which people are ignoring. Mythology has come to be equated with "untrue," and yet it represents the first stories told by mankind.

One of the most perplexing findings is the collection of shapes for the thunderbolt which Zeus holds in his hand. This is NOT the shape of the lightning we see in the sky, and neither is it the shape of an actual weapon. It's a z-pinch -- the highest energy state of electricity which we can today ONLY observe within expensive plasma laboratories. Many cultures attribute this morphology to "thunderbolt", BUT WHY?!

We see highly energetic plasma events all over the universe by now. This is not the quiet, peaceful universe which was imagined back when uniformitarianism took hold. Anybody who claims that absolute dating would, without a doubt, not be affected by a similar catastrophe happening here is making drastic assumptions about what that catastrophe would look like.

But, the situation with conventional science is much worse really, because many cultures appear to record details about what these catastrophes did actually look like. It's widely believed amongst conventional thinkers that the "creation myths" pertain to the birth of the universe, but a much better case can be made that these creation myths are simply the stories of those who survived the last global catastrophe. In the process of ridiculing all of our ancestors as idiots, not worth listening to, scientists have found a way to keep themselves busy (and put their children through college) for hundreds of years.

It never ceases to amaze how many of the so called educated have lost the ability of common sense, like they were told the perfect giant circle arc at lower right Hudson Bay survived in pristine condition after being covered for millions of years by miles of moving ice during the "ice ages". Wake the #$%$ up, this is post ice, this is why the ice disappeared.

I did not realize this kind of discussion might generate so much strongly opinionated discourse! One may of course call certain individuals "crackpots," but what harm is done to the world by passionate speculation? There are plenty of far more dangerous pursuits and practices, such as making war or committing securities fraud on a massive scale.

Ralph, nice to hear such a common sense response, so lacking in this world. I take no offense to your take "passionate speculation", how else could you see it but I promise this is much more. This is eye witness evidence. And I would be happy to send u a copy of my book that more then backs that statement. Remember this is only 12000 years ago that Chicago was supposedly covered in ice.

The evidence is is becoming more clear for the YDB impact, and for several other impacts. Another interesting, history changing impact, with overwhelmingly extraordinary evidence, happened just two centuries ago, in The Mississippi Embayment and was the cause of The New Madrid Earthquakes of 1811-12. Just search "Kalopins Legacy"- at wix.com ,documents and links, "A Few Comments on 1811". Here you will find the truths behind the myths...

Very interesting Kalopin, I had not heard of that one. Happy to send you a copy of my book as well, its time to put feet to fire before we are the eye witnesses. You will see the egyptian and sumerian civilizations were relocations due to another impact you are likely familiar with (burckle crater indian ocean)3200 BC

or even committing securities fraud on a small scale.

To the Hudson Bay poster. Dude, go read. The bay is not an impact crater. And if it were, and the event happened 12000 years ago, everything would be dead. 500km is 3 times the size of Chicxulub *what killed the dinosaurs*.

Brainwashed chicxulub dude, the problem today is people like you "read" and just accept what u been told as fact simply becuase your selfish ilk masters present it as fact. With regards to your chicxulub crater it has been shown this impact occurred hundreds of thousands of years before the dinosaurs extinction, go read that.

1 / 5 (8) Jun 17, 2012
I should elaborate given youve been trained not to think for yourself, we can from this new evidence conclude this chicxulub impact was not large enough to kill off the dinosaurs and therefore there is a much larger crater hiding out there somewhere.
