New Evidence for Giant Impact 12800 Years Ago? Let's Discuss
New Evidence and Persistent Challenges for the Younger Dryas Impact Hypothesis
Examine compelling new findings from deep-sea cores suggesting a cosmic event 12,800 years ago, while critically assessing the persistent scientific pushback against the Younger Dryas Impact Hypothesis.
Short Summary
- A recent study analyzed Baffin Bay sediment cores, finding abundance peaks of high-temperature microspherules and melt glass coinciding with the Younger Dryas period.
- Proponents argue these features, unlike contamination or volcanism, point toward a low-altitude air burst or surface impact by a cometary fragment.
- Critics emphasize that the YDIH suffers from a massive lack of reproducibility across independent labs and timing discrepancies between proposed impact markers (Expert Opinion).
- The standard scientific explanation attributes the Younger Dryas cooling to a shutdown of the North Atlantic conveyor, requiring no cosmic impact.
This discussion cuts through the hype surrounding the Younger Dryas Impact Hypothesis (YDIH). We review the evidence presented in a new paper focusing on deep-sea deposits near Greenland, detailing the specific materials found, and contrast this with the fundamental, existing criticisms challenging the hypothesis's foundational science.

It’s what Randal Carlson and Graham Hancock have been talking about all this time.
Anton, I've been following the theory for a while now and there is a explanation why there is no crater. It's currently suspected that earth might of suffered a comet impact similar to the shoemaker levy 9 impact. The worst of it hit north American glaciers followed by potentially mass air burst events. That's why there is no giant crater. Everyone is looking for a hallmark like chicxulub but not taking into account that the glacier acted like body armor in a way or that pieces exploded in air leaving nothing to find.. Was still absolutely devastating. Considering the black mat layer, whole bunch life below. Bones, tools, mega fauna. After, there's nothing, nothing for a very long time. It killed everything in a manner we haven't seen before. A bullet without a shell casing to find. As for humans killing off everything, oldest modern human skull has been found to be 300,000 years old, foot prints in Mexico ranging 30,000 years, there's a wood structure that's roughly 476,000 years old. There's a site in virginiana that sits roughly 20,000 years. Humans were well set up before that 12k mark. It doesn't make sense to me that we would only kill everything right then during an event that would cripple humanity just as much as everything else. Humans have caused extinctions but the ancients didn't have the technology that we do. Even early guns are a far cry from bows and spears. I'm not saying we didn't dent the populations, but that's an unimaginable amount of animal tonnage to kill with nothing but spears and bows...... Mammoths, mastodons, giant elk, dire wolves, saber cats, giant sloths, armadillo species that weighed 1/2 a ton the size of a van. everything was so dam big and dangerous. Cheers Anton!
As someone who was born and raised, and spent 3 decades in a religious cult, you want people who question shit.
Anton's not perfect. No one is. But he is rare in that he is genuine, educational, and someone whom the average person could aspire to emulate.
One theory about the formation of the carolina bays involves an impact on the ice sheet that splashed huge chunks of ice that impacted across the US South in a swath that seems to point to an impact around Lake Huron on the ice sheet. An impact on the ice sheet would disappear with melting. There is also some speculation that the Younger Dryas was multiple impacts. Long shot? Maybe. Bear in mind that the Chixalub impact was initially denied.
I'm reminded of a statement from an NTSB investigator. "Crashes are almost always the result of many factors occurring at once."
I remember the controversity of the Alvarez impact therory at the end of the Cretaceous era! It took a long time to be accepted!
I'm old enough to remember when the orthodoxy regarding the disappearance of the dinosaurs was gradual climate change and the idea of a asteroid strike was considered fringe unlike now. So I'm willing to keep an open mind to causes regarding the Younger-Dryas climatic shift.
Thank you. I'm so glad that you're keeping track of this controversy. Evidence is all that matters; even the Believers have made some valid contributions.
