The Younger Dryas Impact Hypothesis since 2007

According to Hancock

I recently discovered an essay from Graham Hancock that manages to convey both the profound intellectual significance — and petty scholastic drama — of the Younger Dryas Impact Hypothesis since 2007. Hancock doesn’t note his good timing, but as he writes in 2017 it is the 10th anniversary of the Comet Research Group’s Acapulco AGU presentations introducing […]

Extraordinary or ordinary?: West responds to CBS about latest paper

    We agree with them that glass could be formed a lot of different ways. We don’t have a problem with that,” said Allen West, a retired oil and gas executive who is one of the leading proponents of the theory. “You can get them from grass fires but you also get melt glass […]

Half a loaf from B612: Asteroid data from nuke blast detectors calls out faulty impact assumptions; older impact data ignored; nothing new

Live updates and edits underway Press release from B612 Foundation UPDATE:  B612 Impact Video 4-20-14 H264 from D Josh Rosen on Vimeo.

Only later, with very little digging, […]
