Senior soil scientist Bill Mahaney nails YDI in glacial sediments
A masterful and comprehensive effort here from respected Comet Research Group co-author, Bill Mahaney. Much of the discipline-specific text is hard for the Tusk to fully grasp, and I have had no time to properly review, but I have asked Bill to provide a layman’s summary of the approach and conclusions. I hope to…
Jimmy on Rogan; YDI centerpiece of new novel
Tusk travel buddy from the Egypt 2020 Expedition, Jimmy Corsetti of Bright Insight, appeared last week on The Joe Rogan Experience, the most popular conversation on planet earth. The Younger Dryas Impact was a frequent subject. This single clip was viewed by over 3 million people. Not to be outdone, Comet Research Group resident…
Deep insights from YouTube
As the Taurid meteor season wanes on the approach of Thanksgiving, I thought it was relevant (and economical) to share a couple of recent videos which present the Taurid phenomena from different, but mutually informative contexts. The first is a ‘live shot,’ and the second is a ‘retrospective,’ if you will….
Horrifying event witnessed by humans -- Brown University says desert glass is from space -- not "grass fires"
In wake of Halloween last week a very, very scary scientific paper was published. “Widespread glasses generated by cometary fireballs during the late Pleistocene in the Atacama Desert, Chile,” creates a rebuttable presumption that horrific cosmic airbursts — without leaving craters — have indeed occurred in human history, a central contention here at the…
Authoritative and readable overview of the Younger Dryas Impact debate published in Earth Science Reviews
Indefatigable genius and digital friend of the Tusk, Dr. Martin Sweatman, authored a surprise blockbuster this week. Below is a peer-reviewed and fully accepted pre-online synthesis overview of the Younger Dryas Impact controversy since the very first paper in 2007. ‘The Younger Dryas impact hypothesis: review of the impact evidence’ concludes……
Hmmm...
Avi Loeb is no household name, but he wants to be. The chairman of the Department of Astronomy at Harvard has appeared on more than 50 podcasts since the start of the year. Given a minimum of one hour per podcast, I’d ask for a week’s pay back if I were Harvard. The guy…
Bill Napier's work to warn of increased risk described by Evan Gough of Universe Today
In a nutshell, Napier’s study shows how comets are likely to fragment and lose considerable mass during encounters with the inner Solar System. The debris trail can expand to a cross section larger than Earth, increasing the odds of impacts with Earth. Also, the debris has considerable impact energy. But over time, that energy…
Pro-science skeptic Dr. Marc Defant now supporting #YDIH based on Powell book
Dr. Marc Defant did a great thing this morning by announcing on Twitter and his blog that he had come around to support the Younger Dryas Impact Hypothesis. As I told Marc, my respect for his intellectual integrity soared when I saw his tweet….
Randall Carlson does a great job here explaining a really creepy but profound aspect of the Younger Dryas Impact Hypothesis. Halloween, like death festivals worldwide in late October\early November, reflects the trauma inflicted by the Taurid Meteor stream on the ancients during recurring bombardments. As Bill Napier described it once to me, Earth’s intersection…
Dr. Bill Napier fingers fragmented comet in Younger Dryas and Bronze Age impacts
Folks, I am sorry to have been so scarce in recent months. Among other excuses for the inexcusable, the auto-mailer for subscribers to the site went down, and I felt I needed to repair it before posting. Fixing it turned into a mess which led to my continued procrastination. Much has happened in recent…
Peter Brown publishes Taurid threat paper, dusts The Bos
An instructive video accompanies the paper I’m trying to get out of town for a beach weekend, but I’ve wanted to get this paper up for days. The newly prominent role of the Taurids among American space scientists, with the role of The Bos discussed in a recent Tusk post here, is peculiar but…
The Bos and Vance Holliday in the funny papers
Some wag tweeted this funny cartoon today depicting the current state of affairs in Younger Dryas Boundary Research. The storyboard calls out The Bos and Vance Holliday for their willful ignorance with regard to the Younger Dryas Impact Hypothesis. The clever and extraordinarily well informed cartoonist points out the awkward position The Bos has created…
Mark Boslough discovers Taurid stream threat in late June -- 40 years after Clube and Napier
Oh, lordy, bring me my salts. I do feel the vapours coming on. You could have knocked the Tusk over with a feather at the Apple Store yesterday when my phone linked to the The Bos in the Washington Post, presenting at 2018 AGU, and pimping to the world: The Taurids are a threat!…
Paleolithic Extinctions and the Taurid Complex (2010) Centaurs as a Hazard to Civilization (2015) Excerpted from Wolbach et. al (2018) Astronomical Hypothesis for the YDB Impact Event Regarding the probability of a swarm of cometary fragments hitting the Earth, Boslough et al. (2013) claimed that the YDB event is “statistically and physically impossible,” whereas Napier…
