Challengers to Clovis-age impact theory missed key protocols, new study finds
Eurekalert! ^ | September 17, 2012 | Jim Barlow, U of Oregon

An interdisciplinary team of scientists from seven U.S. institutions says a disregard of three critical protocols, including sorting samples by size, explains why a group challenging the theory of a North American meteor-impact event some 12,900 years ago failed to find iron- and silica-rich magnetic particles in the sites they investigated.

Not separating samples of the materials into like-sized groupings made for an avoidable layer of difficulty, said co-author Edward K. Vogel, a professor of psychology at the University of Oregon.

The new independent analysis -- published this week in the online Early Edition of the Proceedings of the National Academy of Sciences -- did, in fact, isolate large quantities of the "microspherules" at the involved sites where the challengers previously reported none. Lead author Malcolm A. LeCompte, an astrophysicist at Elizabeth City State University in North Carolina, said the findings support the climate-altering cosmic impact, but his team stopped short of declaring this as proof of the event.

The Clovis-age cosmic-impact theory was proposed in 2007 by a 26-member team led by Richard B. Firestone. That team included University of Oregon archaeologists Douglas J. Kennett and Jon M. Erlandson. While other groups have found corroborating evidence of a potential cosmic event, other groups reported difficulties doing so. One group, led by Todd A Surovell of the University of Wyoming, did not find any microspherule evidence at five of seven sites they tested, including two previously studied locations where Firestone reported large numbers of microspherules.

VELIKOVSKY'S GHOST RETURNS

If we are looking for liars, this essay shows us a few. Amongst the numerous insults the 'scientific world' hurled at Velikovsky, one can find the birth of the theory of the greenhouse effect invented by Carl Sagan without which Al Gore would have been unable to threaten us with his Global Warming stick.

The greenhouse effect that exists only because Sagan needed a cover when Venus was discovered to be HOT - as Velikovsky had predicted.

Thanks FN, well stated! Carl Jr wants to use blue-green algae to make Venus into a colonizable, Earthlike planet. What a maroon.

WHAT!!!??? The greenhouse effect is bunkum??? Next thing you know you’ll be telling me CFC’s depleting ozone is bunkum. What’s is all about Ralphie???

Funny thing about how stuff stick with us over the years, or maybe I'm just going senile. Back in the mid 60's I was in the service with a guy from New Jersey whose name was Ralph. He spent much of his time singing to no one in particular, "What's it all about 'Ralphie'". That's my story and I'm stickin' to it...

From the movie, ALFIE.

Maybe you're old enough to remember?
