“The difficulty lies not so much in developing new ideas as in escaping from old ones.”
— John Maynard Keynes
Once again, the Comet Research Group has dealt a blow to mainstream serenity.
In a paper published this week in PLOS One, the CRG’s A-team reports startling new findings from ocean sediment cores that appear to support the Younger Dryas Impact Hypothesis — the audacious claim that Earth was rocked by a cosmic impact ~12,800 years ago, triggering abrupt climate change and widespread destruction.
Deep Impact—In the Atlantic
Using samples taken from the North Atlantic Ocean, the team analyzed sediments dated precisely to the Younger Dryas Boundary (~12.8 ka) and found platinum, soot, nanodiamonds, high-temperature spherules, and other shock markers—all hallmarks of a violent extraterrestrial encounter.
But here’s the real kicker: These are not ambiguous layers from vague timeframes buried under uncertain land-based contexts. These are marine cores, gathered by independent oceanographic institutions, not the CRG. The authors simply requested the samples, ran the tests, and… boom.
And the signal is global. The same markers found in these ocean cores have previously been documented across North America, Europe, the Middle East, and South America—in over 60 sites on four continents.
This study shows that the ocean — which covers 70% of the planet — holds the same smoking gun.
Why It Matters
For years, critics of the Younger Dryas Impact Hypothesis have scoffed: “Where is the crater? Where is the global signature? Why isn’t it in the oceans?”
Well — here it is.
This study doesn’t just strengthen the case for an impact. It undermines a key objection from skeptics like Mark Boslough, who’ve insisted the impact evidence is cherry-picked or confined to disturbed terrestrial sediments.
No more. The impact proxy markers are now found deep beneath the ocean, right where they’d be expected to fall in a hemispheric airburst scenario.
And it wasn’t just one marker. It was a constellation of cosmic indicators — high-temperature microspherules, shocked quartz, nanodiamonds, combustion byproducts, platinum anomalies — found together, in the correct stratigraphic layer, consistent with a single, abrupt event.
Hats Off to the CRG
This work — led by luminaries like James Kennett, Chris Moore and Allen West — is a testament to the unmatched persistence and analytical firepower of the Comet Research Group.
Despite relentless resistance from the scientific establishment, lack of institutional support, and routine ridicule in the press, these researchers have built an ever-expanding library of hard evidence for the YDIH.
They’ve been right again and again. And like all good revolutions, they’re not waiting for permission.
And let’s not forget the implications: This isn’t just about an ancient extinction. It’s about the story of human civilization — how it started, what wiped it away, and what it might face again.
More to Come
The Cosmic Tusk has covered the CRG since our first post in 2010, and we’re prouder than ever to see their work expand into new domains and new journals.
As always, we’ll keep following the data — not the dogma.
Keep your eyes on the skies. And the sediments.
