Hacker News Stories and Comments
All the comments and stories posted to Hacker News that reference this video.I remember hearing on the Joe Rogan podcast[1] about a theory of an impact at the end of the last glacial period, resulting in a short-term reversal of the warming trend known as the Younger Dryas Cooling Event. There was quite a bit of evidence in the form of meltglass and other things accumulating, but the theory was very much not accepted by mainstream science at the time. From the article it sounds like this idea is getting more support.Randall Carlson is pretty out there with his one massive flood theory as opposed to many smaller events. Nonetheless he's not an idiot by any means and he gives an enthralling account of the climate events at the time.
Also it sounds like a much more credible explanation for the sudden extinction of large mammals (70% of species in North America.) Only Africa was largely unaffected. Including 100 million mammoths dying off which was previously attributed to human over-hunting - just the logistics of which with spears and primitive bows boggles the mind.
I highly recommend getting to know the work of Randall Carlson on the subject.Joe Rogan had him on podcast [1] few times.
⬐ NeedMoreTeaOh dear, not content with the usual climate change denial, he's denying the whole of accepted history. Aeroplanes from thousands of years ago?How is this the top comment?
For those that would like to hear a mind blowing discussion about climate (and the earth in general), watch all of the podcasts with Joe Rogan, Randall Carlson and Graham Hancock.They are three hours each and I promise you will learn many things that give perspective on the repeat arguments and confusion about the climate. There are many other podcasts with these gentlemen, but here are three to start with.

⬐ throwawaymanbotJoe Rogan eh.... hmmmm.. dont he have alt-right types on a lot?⬐ throwawaymanbotRandall Carlson talks about the "Holy Grail" the actual Holy Grail..... hmmm...
Looks like the maverick geologist Randall Carlson was right. The evidence was pretty damn good, but many in the mainstream geology had a hard time accepting it for some dumb reason. Just goes to show that real scientists should never bow to consensus opinions. The outliers always advance the fields.Go listen to Randall's Joe Rogan appearances, they will blow your mind:

⬐ kijinThis quote from the article makes no sense to me:> Statistically, impacts the size of Hiawatha occur only every few million years, he says, and so the chance of one just 13,000 years ago is small.
If an event happens every one million years on average, for example, it's just as likely that the last one happened 13,000 years ago and the next one will happen 987,000 years in the future as that the last one happened 999,999 years ago and the next one will happen tomorrow. Even the interval can be highly variable.
⬐ prestonh⬐ mabboBut the total probability of the event happening "recently" (even if this is a fuzzy description) is far lower than the probability of it happening further away. If there's an event known to occur once in a trillion years and we observed it in our lifetimes, wouldn't you think that was remarkable?⬐ todd8Assuming that a meteor impact is totally random (which might not be true because objects that impact the earth could conceivably influence each other through gravity, etc), it is probably best to model these impacts as a poisson process.A poisson process with an average arrival time of one million years means that we would find that if these size impacts happen on average once per million years that on any given day, like the day before this Greenland discovery, we should expect the next impact to happen a million years in the future and the previous impact to have occurred one million years in the past.
If buses arrive randomly and independently on average every 10 minute, then we can expect a ten minute wait at the bus stop if we get there at a random time.
Think of random points on the number line averaging a point every million years. Now throw a stochastic dart at the line. It’s much more likely to land in a large interval not the small ones—-they take up more space on the line. For this reason, the distance between the dart and the next random point is on average one million, not 500,000. So it is very unlikely that the meteor impact was only a few thousand years ago.
⬐ peterashfordYes... but averages are not overly meaningful when considering a single event.Maybe.> The crater was left when an iron asteroid 1.5 kilometers across slammed into Earth, possibly within the past 100,000 years.
So there's a chance that there was an impact in the last 100,000 years. Carlson is saying that there was an impact 12,000 years ago. That's an even smaller chance.
I'm not saying Carlson's wrong, but I am saying you're taking a bit of a logical leap here. Further study could put this impact 1M years ago, or even 40,000 years ago, and either option would mean that this is not the impact Carlson is looking for.
Those who find this interesting might also find the theories of Randall Carlson interesting:https://www.youtube.com/watch?v=R31SXuFeX0A
