Meteor shards linked to massive extinction
International Herald Tribune ^ | 21 November 2003 | Kenneth Chang

Posted on 11/21/2003 12:16:33 PM PST by balrog666

Fragments may be 250 million years old

About three dozen microscopic shards of rock unearthed in Antarctica may be the fragments of a meteor that killed most of life on earth 250 million years ago, scientists reported Friday. .

The shards bolster theories that meteors caused several of the mass extinctions in earth's history when large numbers of species died out almost simultaneously. Most scientists agree that the most recent major mass extinction 65 million years ago, which killed off the dinosaurs, was caused when a meteor struck the earth near the Yucatán Peninsula of Mexico. .

The extinction 250 million years ago, known as the Permian-Triassic boundary, was the largest extinction of all. More than 90 percent of species living in the oceans and 70 percent of those on land disappeared. .

At present, the primary suspected cause for the Permian-Triassic extinction is giant volcanic eruptions in Siberia, which might have induced catastrophic ecological changes. .

Writing in Friday's issue of the journal Science, the researchers report that they found the meteorite fragments in rocks in Antarctica that date to the Permian-Triassic boundary. The mineral composition of the fragments, each less than one-fiftieth of an inch, or roughly half a millimeter, wide, correspond to that of certain meteorites and is like nothing found naturally on earth, they reported. .

In addition, the scientists said, the same rocks had previously yielded soccer-ball-shaped molecules known as buckyballs containing extraterrestrial gases as well as grains of quartz with fractures that indicate they had been hit with a tremendous shock. .

"Clearly, this evidence points toward a major impact at the Permian-Triassic boundary," said Asish Basu, a professor of earth and environmental sciences at the University of Rochester in New York and lead author of the Science paper. That, he said, is "the most reasonable interpretation." .

The same researchers will report at a American Geological Union meeting next week in San Francisco that they have also found tiny metal spheres they believe were part of the earth's crust and melted by the impact. .

Others are not yet convinced. Eldridge Moores, an emeritus professor of geology at the University of California at Davis, described the meteorite fragments as "the most interesting evidence for a meteorite event at this boundary that I've seen so far." .

But, he added, while the evidence for the dinosaur-killing meteor 65 million years ago is a convincing 10 on a 1-to-10 scale, the evidence for a killer meteor at the Permian-Triassic boundary is not nearly as solid. "I think it's now up to 3 or 4," he said. "It's not 9 or 10." .

Douglas Erwin of the National Museum of Natural History in Washington said, "It's suggestive, but it's hardly compelling." Each piece of evidence offered so far has not by itself been compelling. .

The description of shocked quartz, he said, was tentative, even by the researcher who reported it, and other scientists have failed to reproduce the findings of buckyballs and extraterrestrial gases. If a meteor caused this largest of all extinctions, "I find it remarkable that there's so little evidence," Erwin said. .

If the evidence for an impact does become more compelling, that would raise another geological mystery: whether meteor impacts can set off gigantic volcanic eruptions. Huge eruptions in India coincided with the Yucatán meteor impact 65 million years ago. .

To date, most geologists have argued that meteors are not powerful enough to crack the earth's crust. Basu, who is strongly convinced that a meteor struck the Earth 250 million years ago, believes coincidence is not likely. "There has to be a connection," he said.

There was a real smoker of a meteor in SW Arizona last night right before sundown. It left a trail of smoke that lasted at least 5 minutes before it got too dark to see it anymore. The vertical smoke trail did not distort or seem to move at all after the meteor flashed into a bright white/yellow light. This leads me to believe that the meteor got pretty low, before it burned out.

I'm surprised they didn't find shards of prehistoric SUV's during their research.

The scientific case against Craterism

1. Meteor craters are not observed to be happening now.
2. Meteor craters have not been observed to happen in the past.
3. Thomas Jefferson said: "Gentlemen, I would rather believe that two Yankee professors would lie than believe that stones fall from heaven."
4. The odds against a rock falling from the sky in a random fashion and making a crater are astronomical.
5. The second law of thermodynamics prohibits meteor craters.
6. Meteor craters are not mentioned in the bible, and are thus blasphemy.
7. Meteor craters have never been reproduced in the lab, and are thus not scientific.
8. Belief that rocks can fall from the sky promotes hedonism and animalistic, amoral behavior.
9. Craterism is a product of materialism and a naturalistic worldview.
10. Craterism makes no predictions and is untestable; it is therefore not scientific.
11. Craterists point to evidence of micro-cratering, but have no evidence of macro-cratering.
12. Scientists are abandoning craterism because they know it is not supported by evidence.

I'm sure you'll agree that it was very scientific & educational:

Oh, yeah.   The social agenda of creationists is revealed  at last.

2nd Place: "Women Were Designed For Homemaking"

Jonathan Goode (grade 7) applied findings from many fields of science to support his conclusion that God designed women for homemaking: physics shows that women have a lower center of gravity than men, making them more suited to carrying groceries and laundry baskets; biology shows that women were designed to carry un-born babies in their wombs and to feed born babies milk, making them the natural choice for child rearing; social sciences show that the wages for women workers are lower than for normal workers, meaning that they are unable to work as well and thus earn equal pay; and exegetics shows that God created Eve as a companion for Adam, not as a co-worker.

Obviously, it depends on the size and composition of the meteor, speed and angle of entry, where it hits, etc. The Mars-sized "meteor" that created the moon probably made quite a mess. And I'm guessing that a large iron meteor striking Hawaii, Yellowstone or a plate boundary would be almost sure to release lava.

Perhaps not, but it seems possible that a big one could send a shockwave through the earth and set off volcanoes in weak parts of the crust.

ROFL !!!

What is this, 1610? Ok, ok, but seriously, if craters don't come from meteors, then where do you suppose the craters on the Earth and the Moon and Mars and Venus and Mercury come from?

Perhaps this is what kick started the giant volcanoes on Mars. Roughly on the opposite side of the planet is the giant crater Hellas Planitia. I have often wondered when looking at a Mars map if there is a connection between the two.

The same place the earth, the moon, etc. all come from. Why should craters have a separate origin?

I'm just sitting back, enjoying the fact that you have the burden of proving your craterist theory -- or rather, speculation. You say that rocks fall from the sky and cause craters? Okay. You've said it. Now what does that accomplish?

Yes. Observe that the article admits that this, if true, would be an account of "the first and only human in history to witness and document the impact of an asteroid-sized body impacting the Moon's scarred exterior." And then it took 50 years to find what they claim is a likely crater to match up with this alleged observation by an amateur. Imagine ... they were actually able to find a crater on the moon! And suddenly, based on this "evidence," craterism is proved! Right. One dubious data point. Whoopie!!

However, even in the unlikely case that this actually was an observed cratering event, please note that it's a small crater, and it's on the moon! No atmosphere. Earth is a different situation. There are no observed instances of craterism on earth. None at all.
