Supernova debris found on Earth

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

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.

I didn't know Michael Moore was that old!........

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.

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.

Could someone let me know when it gets to eBay?

Actually, predicting the past is no trick.

Accurately interpreting it, however, is another matter.

always my first assumption about "science" in the news. However, just because a scientist is pimping for federal money, it doesn't mean they are 100% off the mark. Merely suspect and worthy of close scrutiny.

Check the data! Always check the data!

Well, since I reference the fact that basically everything (except Hydrogen and Helium) is only possible as the result of a nova or supernova.... it's already on e-bay.

In fact, everything on e-bay is a supernova remnant, if you think about it in the right way....

Supernova debris found on Earth

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