The quote from this piece that gets to me is:

"It demonstrates that the Earth is not independent of its cosmic environment"

Well, duh!

This article caught my attention because of the title. I've always been under the impression that all of the complex atoms that are the basic building blocks for, well, just about everything, including us, was formed in stellar explosions, either novas or super novas. In that case the title is pretty dumb as everything we've ever encountered is basically supernova debris.

On reading the article I thought a bit more about things like global warming. How many billion other variables haven't these clowns taken into account?

Then I was reminded of this thread:

After a Trio of Explosions Scientists say Supernova is Imminent

(http://www.freerepublic.com/focus/f-news/1237727/posts)

I think the moral of these articles is duck and cover!

BS is my first reply. Someone is looking for a grant.

Cosmic fallout from an exploding star dusted the Earth about 2.8 million years ago
Impossible! The earth is only 3,000 years old.< /creationism >

"Ancient explosion may have affected climate..."

No way! Only humans (especially SUV owners") can affect the earths climate.

I'm too ignorant for this thread. But I did read that what we call "Cosmic Rays" are in fact "heavy iron nuclei" iron isotopes stripped of their electron shells, I gather. Traveling at near light-speed, these are by far the most damaging, penetrative form of deep-space radiation and the biggest complication of interplanetary human travel.

"Supernova debris found on Earth"

Undoubtedly more stuff the klintons stole when they left the Whitehouse.

"Some people believe this climate change in Africa was a driving force in our own evolution," adds Korschinek. The argument is that a drier climate in the continent would have forced humans to adapt4, and to spread out to other, wetter areas.

Wow, the Darwin-Supernova theory. Amazing this guy can predict the weather millions of years ago from iron in a rock. Move over, Nostradamos.

2.5 million years is an eyeblink in cosmic terms.

An "At least one luddite has found this thread so far" ping.

[Thinkin' Gal]

Cosmic fallout from an exploding star dusted the Earth about 2.8 million years ago, and may have triggered a change in climate that affected the course of human evolution.

Catastrophism for atheists ping.

"Supernova debris found on Earth"

Could someone let me know when it gets to eBay?

Dis is Y we pay 'em da big bucks!

Supernova debris found on Earth

Yes, right here and all over the Web, too:

"I've always been under the impression that all of the complex atoms that are the basic building blocks for, well, just about everything, including us, was formed in stellar explosions, either novas or super novas."

Actually, many elements are formed in stars long before they go nova or supernova. Once hydrogen fuel is depleted, stars start fusing helium into carbon and oxygen, then those elements are subsequently fused into even heavier elements such as nitrogen and silicon, finally culminating in iron. All elements heavier than iron are formed in supernova explosions. The fact that Earth is rich in those heavy elements is proof that the primordial dust cloud of our solar system was enriched by supernova explosions, which also probably started the initial gravitational collapse of the dust cloud.

Ah, folks; every atom of every element with an atomic number greater than that of iron (₅₆Fe²⁶) is nova or supernova debris. The creation of any atom larger than iron consumes rather than releases energy, and is thus not created during normal stellar fusion.

[The_Republican]

I have always been under impression that EARTH itself was Supernova Debris.

[Ptarmigan]

Supergiant stars have short life in cosmic terms, like 100 million years. Smaller the star, the longer itn will live because it is burning less fuel. It is likely that billions of years ago, there were supernovas not too far from our Solar System. When supergian stars exploded, they produce heavy elements like iron to uranium. When stars have iron appearing, it is sign it will start to die and go supernova. If a supernova happened near us, we would be bombarded with deadly gamma and cosmic rays. It would kill almost all life on this planet.

It is Bush's fault!

[Giliad]

There was a rock...the monkey got cold...and it evolved because it needed to build a fire. Well Halleluiah! They proved the theory. No more debate necessary.

[Redcloak]

It's Bush's fault.
