The Cosmic Tusk

Lake Tahoe Comet Tsunami

One of the best things about the Younger Dryas Impact Hypothesis is finding catastrophic features that may date to the event, but have not yet been directly connected with it. Today I submit one of the finest examples: The Great Lake Tahoe Comet Tsunami. Its is a well-published and uncontroversial fact that in the prehistoric peopled past a gargantuan rock shelf on the western shore of Lake Tahoe…

Con Younger Dryas Impact Papers The Bos & Co

March 2, 2020

A persistent critic of the Younger Dryas Impact Hypothesis and the Comet Research Group has lately gone quiet on our favorite subject. As the supporting papers and independent confirmations have rolled in, Mark “The Bos” Boslough, is scarcely heard from. His last report even seemed a clumsy attempt to scramble on board with a central conclusion of the hypothesis. In this context, it is…

Q&A on Coronavirus and disease from space

Update: Tusk sends protest letter to Space.com Hello readers new and old. Below is the 3rd in a series of communications from Dr. Chandra Wickramasinghe regarding panspermia and the COVID-19 Coronavirus. Please refer to two recent Tusk posts, one concerning Dr. Wickramasinghe’s recent communication to The Lancet, and an earlier post concerning Dr. C’s challenging career. Opinions vary…

#divethenipple

Update: The #divethenipple team is working through a variety of explanations for the feature. So far, we have not found a “modern” cause. If you ever suspected something may be wrong with science look no further. In 2012 brave citizen of Miami Cory Boehne noted that just south of the Port of Miami ship channel, less than two miles from downtown Miami Beach in 30′ of water…

Recent Bolivian Airburst

…the impactor would have encountered the atmosphere at velocities of approximately 20-50 km/s, and the released energy of the airburst would have been comparable to or greater than any known nuclear explosion. [wonderplugin_pdf src=”https://cosmictusk.com/wp-content/uploads/Iturralde-Crater.pdf”] From Wikipedia: The structure was identified on the basis of Landsat imagery in…

Hiawatha Crater: still smokin'?

I’ve previously posted my frustration with the silence concerning the presumably on-going research to characterize and date this extraordinarily young impact crater in Greenland. I’ll put that rant aside, and repeat the establishment line here (unchanged since the discovery): The cosmic impact crater creating, climate changing, 5-mile deep, 19-mile wide, bowl of molten rock is…

Coronavirus from Space?

Update: Tusk sends protest letter to Space.com As regulars know, this is the 2nd communication this week from living scientific martyr Dr. Chanda Wickramasinghe to the Tusk, and this one is perhaps the more pressing. Chandra’s note below, shared first on the Tusk, is to the prestigious medical journal The Lancet and a technical communication concerning the increasingly global scourge of…

Panspermia

February 4, 2020

The Tusk has a flip-side fascination to my obsession with cosmic impact and extinctions: Life on earth and how it got here. Looking into the life story makes a nice yen to the yang of the death story. So I have been fortunate over the years to develop a digital acquaintance and enjoy occasional correspondence with the living lion of astrobiology, Dr. Chandra Wickramasinghe. I have read his books…

Whoops...

I made a bad mistake on a great podcast Friday night. I accused Andrew Scott and a gaggle of other Younger Dryas Impact critics of sub-par work in their 2010 paper investigating carbon spherules, they DID use Transmission Electron Microscopes, and I flat out said they used only Optical Microscopes. Thankfully, since I brought the paper up in the show, I went back to the paper and discovered this…

Hiawatha Crater

January 18, 2020

Fourteen months ago the Tusk could not have been happier. Science Magazine not only addressed the Younger Dryas Hypothesis for the first time in a decade, but did so in a lavish, well-written article. The article accompanied the announcement of what seemed could be the long sought ‘smoking gun’ of the YDIH: A massive crater dating to the start of the Younger Dryas. The astounding…
