Wooly mammoths, giant sloths, saber-toothed cats, and dozens of other species of megafauna may have become extinct when a disintegrating comet or asteroid exploded over North America with the force of millions of hydrogen bombs, according to research by an international team of scientists.
The blast, which the researchers believe occurred 12,900 years ago, may have also doomed a mysterious early human culture, known as Clovis people, while triggering a planetwide cool-down that wiped out the plant species that sustained many outsize Ice Age beasts, according to research published online yesterday in the Proceedings of the National Academy of Sciences.

Its time to reevaluate the threat from space.
Yoo-Hoo, It was the world wide flood during Noah’s time, your only off by 6,000 years. But no, they just can’t bring themselves to believe in God. No, No, we can’t have Noah, we can’t have God, we can’t have Jesus. No, no, we must be are own little gods. No, no, we don’t want to be held accountable by a perfect God for how we live, it must have been a comet, it must have been a meteor!
My wife, as luck would have it, managed to survive.
The flood, obviously. So much time and energy is wasted trying to refute what is obvious.
The Burckle impact crater in the Indian Ocean created gigantic tsunami waves, that pushed megatons of seafloor up onto Madagascar. The vaporized ocean probably made it rain for weeks far away from the crater. Anyone close to the Indian Ocean would have been killed, and many people would have perished in the weather that followed the impact.
It would have been about 6000 years ago, just about right for the Flood.
God could have easily caused the impact and worldwide super rain storm- proof that the Bible is again correct. Noah and his family were warned and survived. You don’t have to discount science when reading the Bible, and you don’t have to discount God when reading science.
Or they could have been killed off by global warming. Or maybe it was Bush’s fault. Or then there is the real possiblility that they were killed off by a flood.
Chicken little was right.. The sky is falling.
All of the Clovis people are here in Miami.
But how could it possibly have been Bush’s fault ... but then ... no that would be too crazy ... what if Bush had access to a time machine and ...

yeaaaah! Remember, like it was today!
Good thing we know how to fight off ice ages now. /semisarc
On average... over eons. Extinction events aren't like John Kerry or Slow-Joe Biden saying something stupid, occurring on a predictable schedule. A comet hits sometimes every 12,000 years, sometimes every 3.86521478 million years.
To get a sense of time... Stretch your arms out. This is represents the timeline of earth's ~4.5 billion-year history. The distance from your left fingertips to the wrist of your right hand represents the pre-Cambrian (pre-complex-life) period. All complex life on earth exists in the time represented by your right hand. And "in a single stroke with a medium-grained nail file you could eradicate human history."*

And, yes, I believe in God... and comets, and asteroids, and meteors.
Well, it’s not exactly a celestial lottery, happening every Saturday Era and Wednesday Era.
How come there is no sign of this major cooling in the Vostok data?
Or a meteor could have caused the flood and men wrote about it. One such book that contains the story is the Bible. The Bible is a book written and printed by men. That we know.
“But no, they just cant bring themselves to believe in God. “
I believe in God and believe the earth is a few billion years older than 6,000.
Good timing for the announcement. This year is the 1500th anniversary of when Clovis’ people whipped the Visigoths at the battle of Vouille.
Do you also believe the sun revolves around the earth and the stars are lights from heaven?
They might not understand really big numbers back then. it might be, even talking in terms of “thousands” was fairly big numbers.
I think my point was, there are some that discount the findings of scientific inquiry because the Bible explains it all; and others who do not look in the Bible, but only go by the slow meanderings of science.
I see value in both approaches, since both are attempts to describe the world and explain what we see around us. Neither are perfect and neither are terribly accurate, but looking at both ways of seeing things helps explain people and their thoughts.

If this stuff happens only once every 1,000,000 years, as we are are repeatedly told -- isn't it strange that it seems to have happened only 1-100th of that length of time in our past?Even if it happened like clockwork, it would merely mean that the next one won't happen for 990,000 years. :') Of course, the 1 myr estimate (and that's just one such) is merely an estimate, and the problem with the real clockwork is that it involves trillions of different clocks running on different schedules. (': I wholeheartedly agree, we do need more observatory capability.
Thanks Fred Nerks for the ping. Just adding, not sending a distribution, due to earlier topic.

This story seems to be everywhere in the news media. it might be a valid hypothesis, who knows, but it is rare for the media to adopt a science hypothesis so quickly across the board. Perhaps it is related to the upcoming launch of the Dawn spacecraft tomorrow.
If God didn’t want science he wouldn’t have given us brains.
Bryson's great but you really should read McPhee's entire 4-book Annals of a Former World series for a better understanding of Deep Time.
Don’t Comet-ize me, bro!
Thx for the tip... I’ll check it out.
Or, if you like time lines. Envisage a time line reaching from the dinosaurs, in LA, to the present day, at Ground Zero in New York, this happened 6 block away or half a mile, not even across the Hudson river....
Consider that carefully.
Golly, why would anyone believe secular ancient Greek science these days? I don't think Ptolemy was no fundie.
I agree, although the Pope thought it was worth censoring and threatening Galileo for upsetting the Greek/Aquinas applecart.
I find it sad that fundies view the scienfic method as a mortal threat to Christianity. IMHO Christianity can handle the big bang and evolution just fine.
I thought Copernicus was a Catholic priest. I’m sooooo confused.
Copernicus purposely had his worked published posthumously. I wonder why?
For the answer to this and other exciting questions, read a book called "Six Modern Myths" by Sampson.
A better discussion of how, when, why, and with whom Coper. wrote his book - and who published it, how, when, and who read it - is “The Book Nobody Read: Chasing the Revolutions of Nicolaus Copernicus” by Owen Gingerich.
I agree completely with one reviewer ...
Fascinated by the marginal notes as well as the antiquarian texts themselves, Gingerich became a full-time historian of science. His thirty-year quest to locate, identify, and study all the early editions of Copernicus’s magnum opus, with a particular emphasis on annotated copies, became “The Great Copernicus Chase.” The chase turned up a rich collection of marginalia, which has led to a deepening understanding of Copernicus’s influence and of the intellectual climate of the era. And it culminated, two years ago, in Gingerich’s weighty An Annotated Census of Copernicus’ De Revolutionibus.
Few people are likely to read Gingerich’s census, but anyone who appreciates the printed word will gallop through his new account of how it came to be. The Book Nobody Read moves around the world like an espionage thriller—from federal courtrooms in Washington (where Gingerich was an expert witness in the prosecution of a book thief), to Beijing, Australia, Soviet-era Leningrad, and the Vatican. Using investigative techniques worthy of Sherlock Holmes, Gingerich has identified the personal copies owned by such figures as Johannes Kepler and Adam Smith. Many, pace Koestler, bought the book to read it; others became buyers just because it was rare and important.
Gingerich describes their lives so vividly that it seems he’s met them in the flesh. Yet whenever the reader begins to tire of historical minutiae, Gingerich throws in charming tidbits of bibliophilic lore. Attentive readers will learn how many books a sixteenth-century printing press could produce in a day, which insects bore round holes through the pages of old books, and how a German library once sold off a copy of Newton’s Principia because it was too heavily annotated, only to discover that the notations were made by Newton’s contemporary and archrival Gottfried Wilhelm Leibniz.
Now that its first editions bring as much as $800,000 at rare-book auctions, De revoutionibus has truly become a book that few can read, at least in its original editions. Spend a few hours, then, with The Book Nobody Read, which, title notwithstanding, is a book to be read by everybody.
Laurence A. Marschall,
Something - we don’t know what - DEFINITELY happened to many hundred tribes and civilizations all about the same time - but far enough back that the living people who wrote it down repeat the same events as stories, not eyewitness accounts.
Discovery/TLC/History Channel had a recent report on this: claim most likely event is a comet/asteroid impact off Madasgascar with wavews wiping out people in Africa, Carib, south Persian coasts, India, Australia, Borneo, Malaysia, etc.

Everything biological is in the proper sequence, and everything geophysical and astronomical (atmospheric, oceanic, vegetation, formation of the seas & continental drift, clearing of the atmosphere, formation of matter, energy, light, and the stars & world itself - and visibility of the stars & moon - is correct.)
Creation even details that birds (dinosaurs) came before mammals.
Leibniz HA! My Latin and Calculus have expired. It’s been too long since they were used.
Since you're using Ground Zero in New York, where I used to drive a taxi, "6 block away or half a mile," is wrong.
For the sake of the argument, let's agree that the axis of Manhattan is on a north - south axis, even though it's really on a north by northeast axis. North of Houston Street 20 blocks equals one mile on the north and south orientation of the grid. Six blocks between the avenue's east and west orientation of the grid was almost a mile, about 6/7th's, depending on where you are in Manhattan. Check a map of Manhattan.
You can zoom into Manhattan, and you can make queries about the distances.
