Problems with the Younger Dryas Impact Hypothesis

[morgan]

It is still only a hypothesis. Good video.

If not an impactor event, then what cleared away the miles high ice sheets from the North American landmass in such a short period, and then explain how the Atlantic Gulf Stream stopped transporting warm waters to the Northern hemisphere at the same time?
We have seen meteors crash into Earth in isolated parts of the world which causing huge damage, like Chelasybinsk in Russia a few years ago, and Tunguska back further, so its not hard to imagine something crashing into a giant ice sheet and wreaking havoc globally. Evidence of impactors are all over the Earth, with thousands of others wiped away over time by erosion.
It seems that archeologists just cannot accept facts like extraterrestrial impact events can cause planetary catastrophes, despite the evidence of Schumaker-Levy, Yucatan impactor, or modern day events, though significantly smaller scale like Tunguska or Chelasybinsk in more recent times.
The archeologists answer seems to be they have no eyewitness account and that everyone who says otherwise is a racist, mysoginistic psuedoscientist. And that's a losing argument.

Yeah Handcock is annoying at best but I really think a lot you dismiss the "Hypothesis" just because he is associated with it. People seem to pick and choose what they want to stress.

I have been looking for information that refutes that Abu Hureyra was destroyed by an Air burst around this time and haven't found any. If you would like to make a video pointing out flaws in that finding in would be interested.


Seems more to support the theory then refute it. Well minus the Hancock style crystal skull flying Atlantean elephant part .. that crap does the idea harm

Thank you. My enthusiasm towards the Clovis Event was sincere. As a historian I needed a piece in my maze, and it fit perfectly. Now I find that it was a provisional piece. Until there´s intersubjectivity, we'll keep using provisional cognition: Science is always evolving and every new discovery demands science updating.

Science is about asking questions and seeking answers.
It’s not about trying to disprove any possibilities. It’s never settled.

Another great, sensitive, insightful video about our historical existence on this/in this evolving biosphere. Thanks

Where did you study? You mentioned your masters professor. This is a topic I have been very interested in, but it seems there is not much content surrounding it. I appreciate your educated explanation! Almost every video surrounding this topic goes into ancient civilizations and conspiracies. Thank you for some good ole fashioned science.

[gregsmith]

there was 1 iron object found. but that doesn't mean there were not multiple impacts of smaller size., there are also craters in Arizona.

[jimellis]

Extarestial impact unleashing volcanic activity...maybe prolonged.?

[taylormorris_]

The pleistocene extinction event is maddening. Someone (not named graham hancock) just figure it out already and let me know. Thanks!

[chrisking]

Shouldn't it be impacts, plural, as in many E.T. strikes over time? That's what I heard across the internets. Nice video though with the editing, voice-overs and graphics. An update with the info you left out might be something to think about. Go get 'em Tiger.

Graeme Hancock and Randall Carlson drive me crazy! They jump on these ridiculous hypotheses and go on to present them, unsubstantiated, to the public. And regular everyday people just eat it up. They are great storytellers, but present themselves as scientists. And then social media spreads their bullshit stories everywhere, and those stories persist even in the face of overwhelming scientific evidence against the hypotheses. Your site gives me hope that science can be presented in a way that can educate the world. Much appreciated. BTW what is your background? You mention your research and education only briefly. Maybe I need to check out your other videos.

I do not know if an extraterrestrial impact occurred near the time of the Younger Dryas. However, the extinction of the megafauna around that time was not caused by an impact.
Most people are shocked when I tell them that surface gravity on PART OF the Earth’s surface was increasing from a lower level at that time. My two books ‘Ice Age Extinctions, A New Theory’ and ‘The Gravity Theory of Mass Extinction’ explain how a gravitational gradient around the globe has happened in the past.

Briefly, when a large surface mass on the Earth moves to high latitude (e.g., sea water to ice), and therefore closer to the rotational axis of the Earth, something must happen to conserve the angular momentum of the Earth. That something is the offsetting of the Earth’s core elements from centricity which results in a gravitational gradient; lower surface gravity in one longitudinal region and a commensurate increase in surface gravity antipodally.
This happened during every glacial period lowering surface gravity in a region. This process reversed during every following interglacial period causing extinctions due to the increased surface gravity.
The question is why was it so devastating in the last interglacial period (20K to 14K years ago)? The graph of temperature during this period does show a greater increase in temperature during the final interglacial. However, a graph of the amount of polar ice melted during this and prior interglacial periods would be of value.

[sharoncole]

After listening to that. I have to agree with you. Yeah it is to bad the ET theory didn’t pan out. That would have been pretty cool. 🌸

[jholt]

The studies that couldn't replicate the findings were doing it wrong.

[merlingeikie]

'Scientists' isn't good enough.
Study design and funding is missing.

[e-memers]

Say if multiple fragments of objects hit the earth could that explain the the difference of the objects. I dont know how do say this without Sounding like an idiot, Vulture stone at Gobekli Tepe has carvings of constellations that could only be visible in the sky in the same time period as the stone claims multiple fragments of comets fell from the sky. This research was not conducted by idiots merely a translation of what the stone was saying. Dont send hate if you dont like it then dont say anything

[goganlole]

well SOMETHING happened. Just because it wasn’t the perfect younger dryas doesn’t mean we should discredit the great exctinction theories. Otherwise we just have to believe people stopped leaving behind archaeological traces for a thousand years or so, just because.

[ltbraca]

The Adam and Eve story is a pretty good explanation if insane and terrifying.

[geofflewis]

..the challenge is, explaining vast numbers of large animals, which had survived numerous previous glacial periods, died out, possibly in months..something big happened.
