Supernova debris found on Earth

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.

In stellar fusion, the process isn't a straight "straight" to iron, but other
lighter atoms fuse creating cobalt, nickel, zinc, etc, are created, but not in quantities
anywhere near the amount of iron.

[RadioAstronomer]

I agree. It is impossible to date anything with any type of isotope unless you have something that you can prove was made at the date you are looking at. A million years, a billion years or 50 years... it does not make any difference unless you already have a sample that was also made at that time. This is all intellectual BS.

Not true. Looking at the daughter product ratios gives the initial date and isotope composition.

I have never understood one aspect of the primordial dust cloud theory of planetary formation.

This may be a really stupid question, but why are various elements contained in deposits and veins? I don't see any reason why iron, uranium, gold and other mineral atoms would gravitate toward each other. I would think that elements would be fairly evenly mixed.

[RonF]

For sure, God did it. Those of us who study physics, chemistry, etc., are simply teasing out the rules of the mechanism He set up to do so.

[Gumption]

I'm pretty sure that all matter has gravity. The larger, or more dense, the mass, the more gravity it has. But I'm just a plumber, so let's ask the main man himself ... Mr. Radio.

[Batrachian]

What you have to realize is that the ore deposits as we find them today are not just as they where right after the planet formed. They're the result of billions of years of geological activity. They've been moved around by plate tectonics, mixed and melted by magma, and shuffled and reshuffled over and over again since the planet first formed.

I'm not a geologist, but I think heavy metals tend to gravitate towards each other in the semi-liquid mantle of the planet because they have similar densities, and so tend to move around in the slow convection currents of the mantle in similar ways.

In short, what you see now reflects not the primordial dust cloud that the Earth formed from, but an Earth molded by billions of years of geological activity.

[Luke]

Nope!

Not without a confrimation ...such as a hammer with an inscription that tells us that this hammer was made in Nashville, Tennessee by the Thor Iron Works on 2 August 1914 AND you've got the ironworker that made that particular hammer testifying on oath that he indeed made that particular hammer on that date.

If a rock is a billion years old... you've got to have another sample of rock that you can prove to be a billion years old. Otherwise... there is not a word of truth in it.

[Dataman]

Howdy, TG! Long time!

You make a good point. Catastrophism on the moon, on Mars, on Jupiter and now a supernova. But catastrophism on earth? Can't be, because it would disturb uniformitarian sleep.

[Redcloak]

It's Bush's fault.

[Phsstpok]

It's Bush's fault.

Redleg Duke, meet Redcloak.

Redcloak, meet Redleg Duke.

The Earth Sun you me everything IS Supernova debris.

[balrog666]

Jeez, did I miss a new physics revolution? I thought every element over an atomic number of 26 was evidence of super-nova activities...

[balrog666]

Nevermind, I should have read on. /Emily Litella mode

[PatrickHenry]

I thought every element over an atomic number of 26 was evidence of super-nova activities ...

Barbarian! Every element is a miracle. Doncha know anything?

[longshadow]

Jeez, did I miss a new physics revolution? I thought every element over an atomic number of 26 was evidence of super-nova activities...

This article isn't going to win any awards for scientific accuracy in reporting.

[SunkenCiv]

A Blast from the Past. Literally.

To all -- please ping me to other topics which are appropriate for the GGG list. Thanks.

Please FREEPMAIL me if you want on or off the
"Gods, Graves, Glyphs" PING list or GGG weekly digest
-- Archaeology/Anthropology/Ancient Cultures/Artifacts/Antiquities, etc.

Could someone let me know when it gets to eBay?

Any element with an atomic number greater than iron is supernova debris.

"It represents an experimental triumph and a milestone in this field," says Brian Fields, an astrophysicist from University of Illinois at Urbana-Champaign. He argues that the result marks the birth of a completely new area of research, which he calls "supernova archaeology"

BS is right.....its called Grant Trolling.
