Ground Sloths in the Sky, With Diamonds

[NQ6U]

Scientists have found a field of nanodiamonds across all of North America and most of Europe and the Middle East that was laid down around 13,000 years ago, the same time that there was a major extinction event. They interpret this as evidence of a comet impacting Earth.

Must've been one heck of an 'event' to make a layer about half of the planet. Sounds about right though. Thing is that events like this aren't supposed to happen in this era of the Solar System. They're supposed to have happened in the early stages of planetary development.

Schumaker was right it seems. We'll see if he's also right about life hitching a ride on comets and asteroids.

I wonder how this 'finding' is affected by this?

Comet explosions did not end the prehistoric human culture, known as Clovis, in North America 13,000 years ago, according to research published in the journal Geophysical Monograph Series.


Researchers from Royal Holloway university, together with Sandia National Laboratories and 13 other universities across the United States and Europe, have found evidence which rebuts the belief that a large impact or airburst caused a significant and abrupt change to Earth's climate and terminated the Clovis culture. They argue that other explanations must be found for the apparent disappearance.
Clovis is the name archaeologists have given to the earliest well-established human culture in the North American continent. It is named after the town in New Mexico, where distinct stone tools were found in the 1920s and 1930s.
Researchers argue that no appropriately sized impact craters from that time period have been discovered, and no shocked material or any other features of impact have been found in sediments. They also found that samples presented in support of the impact hypothesis were contaminated with modern material and that no physics model can support the theory.
"The theory has reached zombie status," said Professor Andrew Scott from the Department of Earth Sciences at Royal Holloway. "Whenever we are able to show flaws and think it is dead, it reappears with new, equally unsatisfactory, arguments.
"Hopefully new versions of the theory will be more carefully examined before they are published," he concluded.

Yes. *sniff* do science before publishing. *sniff*

LINKINATION: Prehistoric humans not wiped out by comet, say researchers

Could this happen again? Hmmm... naw, never.

Is it Political Science or Science Political? I'm all cornfoozed.

I think there is a chance we could be wiped out by a comet or asteroid within the next 5 years.

I wiped out a hemorrhoid once, does that count?

Only if you used Preparation G.

I can't remember what it was, but is was way down in the alphabet.

Not *gasp!* Preparation X?
