Hi guys! I'm an author on this paper! Andrew Moore was approached by the CRG because Abu Hureyra was known to span the YD boundary. When analysis revealed impact proxies, Moore revisited prior interpretations of the site such as a burn layer he previously thought was odd but attributed to cooking fires. There are 5 papers on Abu Hureyra. Bunch et al. 2012, Moore et al. 2020 and Moore et al. 2023a, 2023b, 2023c. There are more than 120 papers supporting the YDIH and about 70 criticising it. All can be read on the comprehensive YDIH bibliography on Cosmic Tusk.
the lack of shocked quartz has been the main whipping stick of the old guard. so imo, this is probably a seminal paper to acceptance of YDIH. congratulations!
@Eyes_Open I wrote a 50,000 word thesis that serves as a rebuttal, though without addressing it head on for the most part. You can read it on Graham Hancocks website. Tere is also a comprehensive rebuttal directly addressing their paper line by line currently in press in a peer reviewed journal, of which I am also a coauthor.
Earth Science Reviews, where the 'comprehensive rebuttal' is published, refused to give us more than 5000 words to respond to their 96000 word ad hominem
@littlefish9305 When history looks back on this affair it will be considered a seminal paper, but because the shock evidence we see at the YDB is essentially a new form, we still have an uphill battle for widespread acceptance.
I just read an article on this and they said it was probably a comet about 80km wide that broke up into many smaller fragments. They should be able to reverse the trajectory by trying to align where the proposed air bursts occurred but also what evidence in terms of impact proxies are going to be found if a lot of the initial explosions happened over ice sheets. How is the evidence going to washout once the ice melts its a tough one to crack but if they could align the trajectory they could even find the remnants of the comet still circling the Earth so they can be properly identified.
comet encke. Victor Clube and Bill Napier published some very good books on it, they argue there are some big chunks left in the taurid meteor stream. interestingly the perihelion of dwarf planet Sedna was near the YD and is due back in 2076. yikes! could disruption of the kuiper belt by Sedna have produced comet encke?
There is coincidence with Laacher See eruption but also in 1783 there have been two events: Laki plus Asamayama . An impact plus a giant eruption would the catastrophe make greater.
Sadly, Wikipedia is often the last to know about anything new. It is "curated" largely by retired professors desperate to keep new ideas out. They will give up, eventually.
This is where I come to when I want to listen to two intelligent, funny people talking and discussing interesting topics. Half the time I've no idea what you're talking about, the other half I'm so fascinated by you two talking, that I can't listen. 😅 I'm always pleased though when I get a notification. And I know that any comment helps the channel grow. I'm sorry I have nothing more intelligent to contribute to the discussion though.
There is not one unintelligent viewpoint when talking about the universe. Plus, I don't get the hype of trying to understand it all. Knowledge is not a thing that keeps me up at night 😂
Once again 9:37 a good discussion, punctuated by your signature sense of humor. I really enjoy this channel in the midst of the kitchen middens of some individual’s flights of fancy. The mention of Abu Hureyra really caught my attention. Years ago I took an upper division course in Soil Science which I found unexpectedly fascinating. Before we got to the nitty gritty of soil composition, we spent the exploration of several chapters on the development of agriculture. One of the sites they focused on was Abu Hureyra and it’s proximity to the species of wild grains that became domesticated, although stands of wild ancestors i.e emmer and einkorn still exist in the area. The text book was quite old even when I took the course because the village site still existed on its ancient location. I still have that book. It was well regarded at the time and quite carefully written to avoid any leaps of the imagination. And as a result of the course I think anyone doing archeological digs would benefit from even a bit of soil science.
If it walks like a duck, quacks like a duck, and looks like a duck, usually it's a duck!!! Why the vitriolic abhorrent opposition to what the facts are indicating, all the ducks line up in a neat little row if you just will look at the obvious evidence, then it all makes sense, Occam's razor, the simplest explanation is usually the right one, that's what we go with in science, what is most likely, and a series of air-burst impacts with a few actually making contact with the ice sheets explains so much, the heat paradox of the former ice age, the massive influx of fresh melt-water, the plummeting of global temps due to the shutting down of the "great ocean conveyor system", shocked quartz and nano-diamonds, Carolina Bays impact proxies that fan out from Saginaw Bay, the Greenland impact crater which has almost exactly 13000 years of new unfractured ice and snow above it. The black mat found at countless sites all over the world dating right to 12,800 ybp, the end of Clovis, and so many other cultures across the globe. Abrupt abandonment of site previously occupied for millennia, evidence of catastrophic floods worldwide, but especially in the American west. So many points that all line up to a massive series of impacts that likely occurred in 2 distinct periods, one around 12800 ypb and a second around 11600 ybp, but for 1200 years there may have been frequent impacts, but with the 2 meltwater pulses it may point to 2 significant impact events, the last of which was around 9600 BCE. So much evidence to dispute with no alternative explanations. It boggles the mind why someone would continue to be so adamant about disputing this "theory" I think at this point it should be accepted as actual fact and universally studied to find out the how, why, when, and wheres etc... so we can properly prepare to defend ourselves from the next one, why is this so hard for people to understand and accept???
Denial of one’s life long education starting to fracture, transitions into ideology, we can observe the evidence of this popping up all over the world…
I don't understand either. It is clearly in mythology, I don't know how everyone missed it. The Mesoamericans sacrificed humans to the Feathered Serpent, from the most recent meteor stream's radiant, so that it would not take the Sun away, again, for long periods of time, Impact Winters. The incredulousness is so persuasive that I have had to research Psychology to understand denial. I am just about convinced it is a genetic memory of the traumas. We know the story : The Shinning Hero fighting the Dragon to save the Maiden. It is in Little Red Riding hood also, as the Woodsman cuts out of the Wolf, the grandma, mom, and the kid, symbolizing the Ages of Man, or The Suns of America.
They still have hard time admitting they were wrong about cities and people in the Amazon. Impact modeling with multiple meteors made the most sense to me.
I postulate that there is an agenda, perhaps unrecognized, that wishes to believe that man is in charge and has full control. Extraterrestrial events, for the most part, are out of our control.
Prof Vance Haynes said that the megafauna were all extinguished in less than a century. If true, that is not predation, as some claim, that is something sudden, like an impact. R
@@dustydesert1674 When did the mammoths go extinct? In all regions at the same time? Extinctions were happening thousands of years apart for some species as per current understanding.
You guys are the best. I can and do watch Standing with Stones over and over again. Great for both inspiration and relaxation. Best natural ASMR documentary. Maybe it’s the bagpipes! Please keep doing what you’re doing.
As a retired geologist, I have worked in impact structures and re-stratigraphic sediments with mineralization and have also learned the trade in the very glacial domains of Scandinavia, Greenland, and New Zealand, a hypothesis saying that globally affected geological and astronomical events is nothing new, there has been deep correlations of such events, like the Tunguska event around 1908. One of my professors in paleontology, Björn Kurtén, from Åbo, voiced ideas that interstadial changes did affect our forefathers, proven by Svante Pääbo et al. Why is this a discussion, meteorites and vulcanism has through all of the planet's history altered the life conditions. Look at the Lockne crater southeast of Östersund; there exists a fossil of an octopus getting a part of the meteorite in its head. Also, during the Ice Age, Sahara was a flourishing Eden, now dried out. What happened to those animals and humanoids. Something happened in Syria during the same period, younger Dryas, forcing a new way of life. A correlation between the dry out of the Saharas and changes in the levant might been ONE of the causes, astroblemes another. I people fights about such, then we are in a bad way. Nils-Axel Mörners Gothenburg theory about the earth magnetics might be a clue, though he was wrong at times and right in others.

@@Deipnosophist_the_Gastronomer who said 30mil years?? I was referring to an event which left dessert glass on the surface of the dessert, which means its very recent, as in less than 12,000 years old, possibly from the younger dryas events infact. The reason for that idea is that the dessert wasnt always a dessert, 12,000 years ago it was green, meaning there would be evidence of carbon, and the fact the glass is found on the surface, not from deep down also suggests its relatively recent.
My own take on the Younger Dryas climate change is a Comet (or loosely held assemblage of debris) was pulled apart in the earth’s gravity field with many pieces raining down across a global swath. The resulting platinum, iridium, micro spheres, micro diamond, deposits combined with global fire storms in the same strata marks the impact event that triggered the collapse of the AMOC water current that keeps Northern Europe warm and thereby greatly reduces ice that reflects solar radiation (a self perpetuating cold that continued until the AMOC was restored 1000 years later.
Check out Antonio Zamora's youtube videos on this. According to his work, more than one comet fragment hit the Laurentide icesheet around the Great Lakes in the USA. This impact led to the formation of the Carolina Bays and Nebraska Rainwater Basins (secondary ice bolder impacts) in the USA and wiped out the North American mega fauna.
@@sciptick Incorrect. Check out his videos. It gets into age dating as well and the incorrect procedures that have been used in dating. A lot has to do with the overturn of the crater lip and where samples have been obtained.
@@justmenotyou3151 thank you. people don't realize that you cannot date ice boulder impacts by soil date testing alone! Zamora is correct and the YDIH group cannot handle admitting they got it WRONG.
@@sciptick I am sorry, but the disappearance of all megafauna in North America and the evidence of tens of thousands of craters radiating outward from a relatively common source is FAR too coincidental to be discounted.

@@swirvinbirds1971 I.e., never trust any authors of any papers? All papers are published by people demonstrating their hypothesis. The people to distrust in this instance are Boslough, Surovell, and Holliday, who are actively destroying their hard-earned reputations. Surovell is still a Clovis-firster. Boslough has become obsessed and does no real work anymore. The real mystery is why. Can it all be Hancock Derangement Syndrome?
I'm certainly not an expert but my understanding about 'shocked' quartz is that the intense pressure wave actually shocked the crystal structure of quartz to a high-pressure form; quartz occurs naturally in several crystal forms (technical names) depending on the T/P* situation of formation. Hope that makes sense. * temperature/pressure
I've been learning a bit of geology and there are so incredibly many forms of silicate rocks... I had to check, shocked quartz is high pressure but not high temp. Discovered during atomic testing, found in impact craters but also caused by lightning strikes so you also need mineral evidence to confirm impact events.
There's a formula to give an age range to moon craters based on how many smaller craters have formed within them, it's very low resolution compared to our modeling of Earth's history. Maybe rovers could attempt to "match" craters with mineral analysis in the future though, which could in turn make the crater dating formula more accurate... very cool to think about
In North America, 12,900 years ago also marks a time of human cultural change-from very large Clovis blade technology to Folsom tools. The changeover is associated with a change in the size of hunted mammalian prey & final disappearance of megafauna other than bison. The much disdained Solutrean hypothesis, though, proposed very similar events as the recent claims you discuss about the YDIH-widespread forest fires and disappearance of the proposed Solutreans who are proposed to have reached North America across the ice-congested North Atlantic from the extended coastline of Pleistocene France/Spain after around 19,000 ya. As long as we keep talking about the possibilities, we’ll keep extending the research to find out more about the wonders of the human race.
Yes, too many Flint hand tools, found from 12,000 years ago to 33,000, & then a SEVER GAP OF 100,000'S of years we find a unknappable assortment of Quarzatite; (Chalcedony) ones?
There is no direct connection between Solutreans and the North American Clovis industry. However, the 5000 years between their invention in Europe and Clovis points turning up in North America is plenty of time for people carrying the invention to migrate incrementally all the way across Asia and then into North America, bringing their tool industry with them. If true, it will take a century of archaeology to prove it.

@@caroletomlinson5480 Laughable? Less likely than independent invention, but still possible. What is laughable is people in North America sitting on Solutrean industry for 5000 years and then beginning to use it after it has disappeared from Europe.
Hi Guys, are you aware of the amazing series of RU-vid videos by Dr Martin Sweatman surveying and criticising the ENTIRE YDIH scientific literature up to about three years ago? Here is the link to the playlist: ru-vid.com/group/PLftb0lOpSe9PvJhFKSueZV9Wrz4g1qRkr In this series Dr Sweatman is sharply critical of the scientific methodologies employed by the YDIH critics. I don't have the detailed scientific and statistical training required to assess what he says in detail but it seemed rather compelling to me. No coverage of the topic is complete without a look at this material, imho!
@@qui-gonjay2944 - Solar events are brief, like the last one that only effected the atmosphere for a few days. Full solar cycles last from 9-14 years; solar maximum lasts about 2-ish years. The Younger Dryas period lasted from about 200-400 years.

Unfortunate example of why “ the shoemaker should stick to his last.” You two seem to be real experts in archeology but not in the physics and chemistry needed to perform a serious evaluation of this hypothesis. Just let this alone.
Thanks for your so balanced and open-minded discussion of the Younger Dryas impact theory. Two comments to parts of your presentation: 1- Besides the possibility of the Greenland impact, there is also suggestion of the major impact being on the ice sheets over the Great Lakes. With the depth and sediments of a lake like Superior, it may take much more time and study than it did for the Chixalub impact that doomed the dinosaurs. Anthony Zamora promotes this theory, and includes the formation of the Carolina Bays from this time. 2- I have to wonder if some of the resistance in parts of the academic community comes from their frantic realization that if this theory proves plausible-- which as you stated already seems to be the case from all the impact proxies all over the world-- that it may lend credence to the many researchers and scientists that posit the existence of a lost, world-wide, highly advanced human civilization destroyed by this cataclysmic event. Without any tinfoil hats or aliens in the mix at all, it does seem like so many of the earliest elements of some of the earliest civilizations we know sprang into existence with little evidence of development -- legacies of the bands of survivors. Thanks again for this presentation and all your great work! The YD theory defintely checks a lot of boxes in this regard.
Maybe if the Hancock type fraternity hasnt tried to link this to their Atlantis ideas fewer people would be agin this idea. If it was just questions of evidence for a catastrophe unlinked to fantasy it would be more acceptable.
No he does not. He ignores dating work, has an ejecta curtain that dwarfs even the Chicxulub crater, has never even shown an impactor can create a perfect mathematical ellipse, yet alone the bays themselves show everything from wind migration (GPR imaging of Herdron Bay) to undisturbed sediments under the bays showing no impact formation. The Geomodels has some really good videos on the Carolina Bays. Curious Being, although I disagree with her Ancient lost civilization stuff, also has a good video about the Carolina Bays.
@@swirvinbirds1971 I think the minimal work performed on the raised rims is consistent with his dating modeling. The ice is a different beast from the rocks outskirting Chixulib, thus, the wider curtain cannot be discounted for this reason, its cannonball trajectories. Zamora does some field work on the wind erosion proposed by Prince in river beds that lends to his consistency as well, but, the issue is dynamic, despite this aspect of statics where the center of the target is dismissed. Is thatore willy nilly than true recorded history of the outlying areas? There is an enormous amount of shared consistency in the alignments in the central regions, so, why they are called Carolina Bays and not Georgia Bays? Pointing to an energy equation that seems to be a singular blast rather than spread out has the center of the target in its sights, I think. Accounting is not all discounnting.
@@RobertMStahl His dating modeling? He is a computer science guy with no expertise in the field and in no way a Geologist. Minimal work? Lots of dating work has been done. What's minimal is dating work that would agree with Zamora of which there is none. We have impact ejecta curtains on the Mars ice cap and they are nowhere near the size of this proposed ejecta curtain in relation to the crater and Mars has a much thinner atmosphere. Btw they are called different things in different areas and their morphology changes as well. In Maryland, they are called Maryland basins. Within the Delmarva Peninsula, they and other coastal ponds are also called Delmarva bays. The word Carolina Bays evolved in papers studying the Bays in Carolina.
@@RobertMStahl lots of work have been done on the sand rims and the fact that they migrate. Dating work on the sand rims show bay migration. You can find these same raised sand rims on Thermokarst Lakes as well.
This story is the grift that keeps on grifting. Very little new here. yeah, exactly. It’s always the same core group, lead back the guy who runs the Cosmic Summit pseudoscience conference, and Allen West, who was convicted for fraudulently claiming he was a credentialed geologist when he wasn’t one. And the group is funded by christian fundamentalist trinity college, where they were trying to find proof of the biblical sodom story. The greenland ice core PT spike was dated to like 50 years after the start of the younger dryas, and after the wildlifes had already started, according to the original authors of that study. They also never address all the other studies that haven’t been able to replicate their same results, or the fact that the black matt layers are actually organic, formed from natural wetland, and that those also aren’t constrained to only the younger dryas boundary, but rather start much sooner.
I'm wondering what levels of mass potentially could hit the earth when passing through a large comet's tail? (I'm sniffing a Hollywood disaster movie here - nothing to shoot down).
I will continue to keep an open mind since I have no expertise in this field. I will wait for experts to go over this paper and hash it out. I love this about science.
I actually hate this about science. because many times someone gets the correct answer the first time, but (especially now in modern academia as most "scientists" are just beauracrats masquerading as scientists... and have no interest in truth seeking. instead they are much more consumed with reputation, career, and money) some butt-hurt "scientist" goes about not disproving the first paper, but merely casting doubt upon it by claiming "method inconsistenty" or some other bs. never actually showing why their paper is wrong, but merely throwing enough shade to cause an inkling of doubt because their methodology wasn't 100% all encompassing, or that another way to check something may exist. the entire point is to just keep someone else from getting recognition
A comet's tail is not going to cause any damage to Earth. It's just widely dispersed dust. Neither would it produce some of the items you were talking about like shocked quartz and microspherules. Those would be the result of an actual collision.
the remnants of comet encke have laid down debris and dust in an earth crossing orbit which the earth still encounters today. some of that "dust" is substantial and threatening to life on earth. bolide airbusts produce extreme pressure and temperatures many times hotter than the sun.
I may be behind a bit, but they do not seem to consider the possible impact site on the N end of Greenland, still covered in ice now, but drains out impact-related material. Can't recall the paper now, but these guys don't seem to have seen that?
The vitrification of granite. Please compare Peru. Somehow it's always been that archaeology stays in the eastern hemisphere.It's all focused on northern European ice sheet when there was dry land, warmth and humans in South America and probably Antarctica.It's just too far away from Europe to be studied LOL. Thank god for lidar. We're only recently been able to confirm how many fishing villages went under water. . . . .and that brings us close to solving Nazca. The stones of the Andean cultures. You can see the difference over the ages. Indeed there is the possibility of eruption onto glacier, heating and freezing (and likely "cracking" granite), but not anything we can reproduce. Oh the tales of crystal skulls and other stories could have basis. you just don't know what you don't know.
Ah, yes, science at work. As a PhD chemist, I’ve been involved in or spectator to a variety of controversies and the factions, papers, talks and personalities involved. I’m reminded of a Max Planck quote “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”
I've read two books about the Carolina Bays, elliptical depressions who's long axes intersect in the Ice sheets of northern North America and Greenland. I've also seen mentions of a possible crater detected under Greenland's ice sheet. The depressions most common in the Carolina area also extend as far west as Nebraska(?); are these all connected?
@@littlefish9305 - The eastern coastal plain depressions range from New York to Florida. They are circular to elliptical in shape. (If made by large incoming debris from somewhere up north, wouldn't they be oval instead?) Bays were dated in the Carolinas and Georgia, as can be found in a certain online encyclopedia: _"The dating of the sand rims of a number of Carolina bays by optically stimulated luminescence (OSL) techniques has yielded ages ranging from ~109,000 to ~2,000 years ago, but most ages from the sand rims range from ~40,000 to ~11,000 years ago._" Nebraska's Rainwater Basins range in shape from irregular, circular, semi-elliptical, elliptical, to lunette ridges. Their age ranges from 28,000 to 50,000 years BP.

I like pre-history. Once you have studied most of what there is to know about written histories from the Persian Empire to the British Empire there is nothing new left to learn except pre-history.
Meteor or not, the YD was definitely a global catastrophe that had people everywhere transitioning from good food (big game essentially) to much lower quality food: mollusks in Europe, acorns in North Africa (causing a horrible epidemic of cavities) and grass, almost literally "grass" (that's what cereals are), in the Fertile Crescent from Sudan to the Zagros. Places like Ireland saw their climate radically change from modern temperatures to Greenland-like ones in a matter of months. Some sort of catastrophe it was definitely. If it was indeed caused by a meteorite or comet impact, for which there is at least some serious evidence, I lean towards but unsure.
Read The Comet Research Group Publications, it is assuredly space fall proxies covering 1/3 of the globe. There were hippo's in the Saudi Arabian Peninsula just prior.
How do you explain the warming of the Southern Hemisphere while the temperature of the Northern Hemisphere dropped? A change in the "Atlantic meridional overturning circulation" can easily explain both conditions and is something that we may be facing again in the not too distant future. With the disruption of the circulation, the Gulf Stream will cease bringing warm water north nd cause significant cooling.
@@MossyMozart - Not sure, it's something I was unaware of before you asked. But after a cursory search I found that a 2021 paper on moa paleo-ecology in NZ (Richard N Holdaway, "Palaeobiological evidence for Southern Hemisphere Younger Dryas and volcanogenic cold periods") seems to contradict the previous papers (Kaplan 2010 and Carlson 2013) that claimed that there was a warming instead (based on glacial retreat in a key paleoclimate research site also in NZ). Per the moa ecology paper, NZ experienced cooling for all the YD period, just as Europe. Anyway, the meteor and the oceanic stream system shift are not in contradiction: a meteor could hardly cause a thousand-years-long climate shift like that... but it could devastate some glaciers pouring massive amounts of cold freshwater into the North Atlantic and radically disrupting the AMOC (Gulf Stream system). The persistance of this short ice age clearly indicates that it was not just the meteor and maybe it would have happened anyhow without it, that the North American ice shelf suddenly pouring into the North Atlantic was the real cause of the YD. However this pouring may have been triggered by a meteor anyhow.
@@MossyMozart "How do you explain"... Maybe the global climate is a _complicated subject,_ often involving counterintuitive effects? Big events often produce big changes that cause further big changes, some of which might be in ocean circulation. Anybody pretending to know all about how climate works is visibly pretending, and maybe wishing. Wishing is incompatible with science. Stop wishing.
LOL ... the pushback about Younger Dryas Impact hypothesis seems to be due to an offshoot hypothesis that Cromagnon emigrated from Europe to the Americas along the ice margains and were later wiped out by the impact. As I understand it - some have looked at the Clovis points and said those look like an improved version of the spear points found in Europe and it spread around. On the Younger Dryas Impact - I have heard arguments on both sides and I am confused.
@@AustinKoleCarlisle To be honest it might not -be - and I am an outsider looking in so I have no specific knowledge other than videos reguritating others writings. The very first time I heard about either they were connected - where the North American Solutreans were wiped out by the Younger Dryas impact. The arguments against impact theory are so vehement; it reminds me of the arguments in the 90s of the out-of-africa vs regional evolutionary theories. However. maybe the excessive pushback on the younger dryans impact therory is just part of the general pushback against pre-clovis sites. There has been at least 30 years of denial about pre-clovis sites in the Americas, where only relatively recently the mainstream has grudgingly admitted that it might indicate earlier human habitation of the Americas. Yes, my arguments are kind of a mixed bag here.
@@tacitus7797 to be honest, the pre-clovis sites in the eastern us might be the result of the cataclysm causing a massive erosional unconformity in the geology, occasionally putting clovis points on top of older soil which gives the illusion they are older than what they really were.
In a hundred years from now when people look back, what are they going to think of us? *Join the Enlightenment, support Secular Humanism, today.* thank you
At the moment there is only correlation, not causation. It is like asking, what caused the megadrought that ended the Assyrian Empire? If there was an actual megadrought.
There is a crater in Greenland, but it's dated to 50 odd mya. What impact mechanism would cause a cooling for so long and just as quick warming at the end?
Dating on Hiawatha is far from secure. It amounts to wishful thinking by a some who wish the YD-coincident impact were not proven, and wish that proof depended on a connection to Hiawatha.
So you two bright lads won't admit that this planet gets slammed by big rocks on a regular basis? Why does the moon look like the butt of a shooting range?
Possible craters have been found in several places in Canada. They appear shallow as you would expect in these circumstances. I read the papers that mentioned this years ago but I think it was Firestone and West et al.
@@donhillsmanii5906 everyone please look up Antonio Zamora's channel and watch his content, he explains all of this perfectly with his glacier ice impact hypothesis.
I imagine it’s passing through a comet tail. In Earth high altitude, like the plasma burn in a pulverised coal blasted furnace. That is in constant intense glow. Being in Power station experience . The evidence logically backs this even stronger hypothesis.
@@Eyes_Open yes, the comet impact put untold amounts of water vapor into the atmosphere which subsequently rained down into the atlantic and shut down the haline conveyor and cooled the northern hemisphere while heating the southern.
I would welcome a session about Tim Rowe's securely-dated 37kyo Hartley mammoth site. Everybody seems just as afraid to mention it as they are the comet strike.
Plenty of impact craters have not been dated as they're inaccessible, others haven't been studied because of time and cost. "Where's the impact crater?" shows non scientific bias.
thank you. If the scientists, who studied those things thoroughly have such different opinions on 'what really happened' (they even fight eachother!), I don't feel bad about having my own opinions 😊
How does an airburst cause shock metamorphism of quartz grains? Given the pressure required to generate shock lamellae in quartz is >12 gigapascals, but the maximum overpressure ever observed in e.g. a 20 gigatons thermonuclear explosion in the Earth's atmosphere was only 170 kPa (0.17 gigapascal). Also, how does an atmospheric shockwave result in a shockwave in rocks? Previously, every single example of genuine shocked quartz was seen in or was associated with a confirmed meteorite crater, where an asteroid or rarely a comet physically hit the surface of the Earth, generating the nessisary pressures required. As far as I know, the atmosphere of the Earth isn't made of sand.
Yeah but this is foolish to get stuck up on, just because Graham Hancock got his hands on some good evidence but edged it on kookoo shit, doesnt mean we cant consider the real possibilities of proto-societies existing well before 3000 BC, to the order of thousands of years. These are entire histories we're missing out on by bah-humbugging the entire debate over some dopey old journos interpretation of the hypotheses that you can make from this sort of evidence
i started with the amazing randall carlson podcasts and delved further and see the weight of the evidence surely means catastrophic geocosmic impact with comet fragments. and a side issue, i see a graph of ice ages shows we may be tipping towards another. that's why i personally put the danger of warming climate down the list of earthly and human perils.
Even if there was an impact that time, it's not full explanation. There seem to be periodic event of similar kind throughout ages (like last 100-200k years). So a periodic rather tlthan one-off cause is likely.
Great video. Thanks for explaining the name, Younger Dryas, too. Curious, then, why the flower was named that, I ran into a bunch of Greek mythology with several characters cited but most depicting him as a spectacular warrior. Which makes sense if you're a tough little flower growing on glaciated terrain.
Comet STREAM: A large comet in the process of fracturing into much smaller, disparate pieces. Imagine thousands of Tunguskas (+/- an order of magnitude) in the space of a few days.
If it were a comet similar to Comet Shoemaker-Levy 9, it may have broken up into large icy masses. Ice melted in our atmosphere leaving rocks and dust which spread around our planet. heating the earth and starting fires. Following the fires, the atmosphere would be cooled by the smoke and clouds of the condensing water vapor. Consequently there may not have been pieces of rocks large enough to survive entry into the atmosphere and leave large impact sites.
All well and good. Thank you both so much for this. But ~ Thank you for your patience with me. ~. Pulllezze consider changing the name of you post here. ~~~. NOT PRE HISTORY ~~~ please consider calling you blog the DEEP HISTORY or something about that. Consider MY BIG CURRENT OBSESSION ~~~ A 20 Thousand Year Calendar. ~~~ Yep. Just call it a Calendar for Human Culture. All the guys who you mention here. And yes, that one bad day in Michigan, The ice in SPACE. It's the Impact Basins. The nice neat pattern etc. Michigan. Then 1400 miles out and the impact zone via Lidar imaging. But just a simple Calendar. Accept that (probably longer) the Culture of the Human Race has significant events that can be placed on a Calendar. I suppose the Gaza Plateau, (you know, the pyramids etc) and the Bible, the Koran, etc are but a small portion of TWENTY THOUSAND YEARS. So there is this, there is the deep bury of the Eastern Island monoliths, that amazing underground city, that round anomaly in the western Sahara, A river there?, The "filling up" of the Mediterranean Sea. For me here in the USA, The loss of all the flora and fauna at a certain moment in recent time. But more than that. Has anyone noted why it's all about the so called Birth of Human Culture there in the middle east. Why there? Well that's because of that bad day in Michigan. Really just one bad day. Glacial ice, Kilometers thick. Whoosh. Up in space and then down in a pattern. The impact craters, a distinct pattern 1400 miles out. Yea you guys are You Tube Click Baters. You know. Simple. Antonio Zamora. He's got it. Shame on you. BS I'll tell ya. But really a Calendar. Twenty Thousand Years. We should be able to at least do that. Don't you think? Your conversation is Sophomoric. Showing some ignorance on purpose are we. ??? Not so sure about this? Oh well. You Tube does it again.
It's been said that Gobekli tepe was built and then at some point purposely buried and it always struck me as being unlikely as burying it would require mutch more work than building the site and perhaps was the result of a debris flow from flooding related to impacts or otherwise !
I have to say that as an archaeologist, I have always preferred "all of the above." All of the various "explanations" have some sound reasons for thinking they may hold some support. Also, there is the recent impactite discovery in Chile that is about the right age.

Hay COUZINZ ~ THX debate good🇨🇦 from Wiki - "Pardee's and Bretz's theories were accepted only after decades of painstaking work and fierce scientific debate. Research on open-channel hydraulics in the 1970s put Bretz's theories on solid scientific ground. In 1979 Bretz received the highest medal of the Geological Society of America, the Penrose Medal, to recognize that he had developed one of the great ideas in the earth sciences."
I have a question for Rupert. Were you ever a narrator in a TV series called Lost Treasures of the Ancient World-The Odyssey-Ancient History Documentaries? If you didn't, well you have a voice doppelganger with your voice and even inflections.
Humans of the modern variety were around at the time of the Younger Dryas- and long, long before that - at least back 75,000 years from “the present day”. So, they would likely have been using spoken languages (not just incoherent “caveman” or teenage grunts 🙂), and expressing themselves artistically in the form of art (including carvings or “rock art”) and storytelling (including oral myths). So, putting together the geological evidence from around the globe, archeological evidence (including changes in flora and fauna and especially the loss of large animals and large trees including from well North of the Arctic Circle), surviving art work (including petroglyphs such as the squatterman), ancient symbols (such as the 200m square sauvastika of the Hopi and ancient stories and myths (such as the original sun, the purple dawn) and commonalities in myths around the globe, particularly around the planets (for example, the Blackface tribes of North America describing Mars as “scar face”, Venus as being first benign and then changing into a raging Medusa), the magnetosphere of Venus stretching as a Comet tail almost to Earth’s orbit around the Sun, the microspherule-rich “muck” (frozen mangled flesh) of the Yukon and - unbelievable though it appears, if you believe our ancestors weren’t stupid imbeciles who just made up implausible stories for the hell of it that just happen to share large elements around the globe from supposedly disparate, isolated communities, then you must conclude that the myths known today collectively as the Saturn Myth must be true. Anyway, I recommend reading the God Star series of books by Dwardu Cardona before deciding for yourselves whether our ancestors were struggling to try to describe “changes in the heavens” of cosmic proportions for which they did not have a deep “scientific” understanding of - or they were simply collectively all just “loony tunes” fantasists - even though they were supposedly still rational enough to survive major changes in their environment. And then, of course, there are all those unexplained “antediluvian megalithic/cyclopean structures” around the globe with remarkable similarities in size, weight (up to 1000 tons plus), form, geometry, tool marks and precision - and the many, many complex underground “living spaces” (away from the surface, but for what purpose?) and only a fool would say that the “official view of prehistory” is complete and accurate.
The shocked quartz in MD is from the Chesapeake Bay formation from 31 million years ago. Not the younger dryas impact. Out in Southern west virginia, I've got evidence of the the younger dryas impact on the side of a mountain at about 2800 ft above sea level facing north west.
The yd happened 12,000 years too soon, didn't help too much, why????? Thats the question. You guys never introduced yourselves as in your level of science to speak of such things.
The only question remaining? ..nice and quick or long slow and hard? hahahaha. Surprise me! Oh! and leave a message before you turn out the lights....🌍✌️🌎
Basic science fan/average Joe. Maybe due to the fact of watching The Why Files or reading other publications, I find myself to be a fan of the YDIH. To me, it just makes sense.
The exact data is 10,844 BCE. An Ice Age comes about in a completely different way than has been told so far. An Ice Age is the result of the peak of five natural disasters that occur one after the other in a cycle. That cycle is mentioned in several old books. The cause is the strong gravitational pull that a rapidly passing planet exerts on our Earth. That planet 9 circles the sun in an eccentric orbit. As it approaches the sun it has great speed and after the passage the speed decreases again and planet 9 disappears from our view for a few thousand years. This great attraction pulls the seawater up even "above the highest mountains". That water freezes at that height. As the planet moves away, its gravitational pull diminishes and the frozen water falls back onto Earth "in blocks as big as mountains." As a result, the northernmost part of our planet will be covered with ice in no more than two days. The sea level is now much lower and after some time ice starts to melt. That goes on for a long time. The previous Ice layer was formed in the year 10,844 BCE and the next one comes in the year 14,356 CE. Before and after the Ice Age, there are four natural disasters that cause a great flood that kills many animals and people. All crops and harvests are also destroyed. This is Ancient knowledge that is available to anyone who seeks it. But that knowledge has been forgotten, ignored or denied by all scientists.We explain much more about planet 9, the recurring flood cycle and its timeline, the rebirth of civilizations and ancient advanced technology in the e-book: "Planet 9 = Nibiru". It shows abundant and convincing evidence both in text and many depictions. It can be read on any computer, tablet or smartphone. Search: planet 9 roest
Many years ago when the first research results were being published I watched an interview with some gatekeeper-naysayer who looked very seriously at the interviewer's camera snd said "Show me the hole!" Completely unashamed to have no explanation for global distribution of iridiom rich tectites, ash and all the rest.
"The first principle is that you must not fool yourself and you are the easiest person to fool. Richard P. Feynman". Prehistory guys also seem pretty easy, but I'm sure peddling disinformation will be profitable.
Pole shift, CME and comets may all be part of the same phenomena . Maybe the magnetosphere does not just weaken during pole shift, perhaps for a moment, it actually attracts comets and meteors while also being hit with plasma waves from sun. We will soon find out. Suspicious Observer is on RU-vid, if you don't already know, highly recommend.
Help! I keep reading that agriculture was introduced by people who migrated into new lands bringing their technology with them (what happened to the people they replaced?). Alternatively I read that there was a gradual change of food source practices which eventually became agriculture. This hypothesis on the YD event helps the gradual change theory. But genetic studies also seem to show otherwise. Which version do you two feel is more likely?
Thank you guys for discussing this hypothesis, this one could be coming home, please look at the black Matt layer, it could be very significant, fringe/ citizen science can on occasion have relevance subject to scientific peer review naturally.
If the Younger Dryas lasted 800 -1000 years as the ice oxygen isotopes suggest that is too long a time period for asteroid or comet particles or exploded dirt to stay suspended in the atmosphere isn't it? Certainly too long for any ecosystem vegetation not to regenerate. To maintain sun blocking volcanic dust you would need long term continuous eruptions like the Decan Traps or Siberian ones that contributed to the K/T and Permian extinctions. Maybe a multi factor cascading set of events if the comet tail evidence is that strong. Hell I still haven't found a strong reason for the turning of the Sahara into desert from grassland 6000 years ago.
I'm more curious what ended the Younger Dryas, that broke the ice age pattern that had been sustained tens of thousands of years previous. That sudden dip for a thousand years was an almost regular event and not a one off but the END of it. . .well, that is very different. What ended the ice age? That is a lot of heat to explain.
There's a large impact crater in northwest Greenland that was discovered a few years ago. It's covered by the ice sheet, but it's near the edge. With the limited research that's been done so far, they think it's a fairly young crater. It's possible that it's an impact crater from the younger dryas period, but no one knows at this point in time.
