#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.

Hiawatha Crater

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.

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…
