Re: Tectonics etc.
Why? There is not one thing in the account to suggest anything other than natural processes.
how about the word "god" for starters?

Re: photo
It was merely one of dozens of things in that article that seemed deceitful to me
because you're looking for deciet.
the rest of us recognize the idea that for pre-history, there are no photos. and so the little pictures that go with newspaper stories are ALWAYS artist's conceptions, and not neccessarily accurate to the most munute detail.
for instance, when an article shos a picture of a dinosaur, we generally understand that it might have looked different in terms of coloration and patterns. and we understand that it's not a photo.
Do wwe have to run out this thread on this nonsense?
you brought it up.

Continuing with the post#1 links
Turns out I don't have a problem with how this article is written. It covers the necessary information, it's clear and it sticks to the point.
Science Daily article
Meteor Likely Caused Earth's Greatest Extinction Event
* "About 60 meteorites five or more kilometers across have hit the earth in the past 600 million years. The smallest ones would have carved craters some 95 kilometers wide.
* "Most scientists agree that one such impact did in the dinosaurs, but evidence for large collisions coincident with other mass extinctions remained elusive -- until recently.
* "Researchers are now discovering hints of ancient impacts at sites marking history's top five mass extinctions, the worst of which eliminated 90 percent of all living species."
Becker's current research at the Graphite Peak in the Central Transantarctic Mountains, Antarctica, described in the recent Science article, has revealed several meteoritic fragments, metallic grains, in a thin claystone "breccia" layer. Becker and the research team believe this to be strong evidence for a large impact that appears to have triggered the Great Dying. Breccia is ejected debris that resettled in a layer of sediment. The metallic grains also appear in the same layer (end-Permian) in Meishan, southern China. They also resemble grains found in the same strata in Sasayama, Japan. (The earth was a single continent at the time of the impact.)
I think the most plausible theory from a YEC standpoint is that the continental movement probably began at the time of the Flood. I'm also still trying to defend my "just a thought" about meteorite hits occurring in conjunction with the Flood event, so the geography as described above would put this hit at some distance from Noah and company, across a very large continent, a continent possibly still submerged in the Flood but possibly not; that is, it could have occurred after the water had begun to subside, leaving exposed land for all that distance, which would break the waves of any tsunami before they got to Noah's part of the ocean. But by that time he'd be on land anyway. If a tsunami did travel through the Flood waters across such a huge distance, there wouldn't be enough power left in it to do any damage to Noah's ship by the time it arrived.
But so far I am not convinced of the size of this meteorite. A meteorite I'm convinced of, just not the size of it or the timing of it.
The team also found "shocked quartz" in this same layer in the Graphite Peak. In the Scientific American article Becker explained, "Few earthly circumstances have the power to disfigure quartz, which is a highly stable mineral even at high temperatures and pressures deep inside the earth's crust." Quartz can be fractured by extreme volcanic activity, however, only in one direction. Shocked quartz is fractured in several directions and is therefore believed to be a good tracer for the impact of a meteor.
Again, this is a much better report than the previous one. It's making a lot fewer broad statements and the evidence is clearly discussed. OK, shocked quartz is a sign of a meteorite impact. No problem.
The researchers are somewhat surprised that they have not found the strong presence of the mineral iridium in the Graphite Peak work. In an e-mail from Antarctica Becker stated, "Interestingly, we do not see a strong iridium anomaly (the impact tracer that marks the Cretaceous-Tertiary boundary or the dinosaur extinction event)."
As she explained in Scientific American, "The first impact tracer linked to a severe mass extinction was an unearthly concentration of iridium, an element that is rare in rocks on our planet's surface but abundant in many meteorites. From this iridium discovery (in 1980) came the landmark hypothesis that a giant impact ended the reign of the dinosaurs —— and that such events may well be associated with other severe mass extinctions over the past 600 million years." The discovery was strongly debated around the world and scrutinized by geologists.
The problem a YEC has with this is that the idea that this wiped out the dinosaurs is based ONLY on the layer in which the iridium was found -- a thin layer of it atop the layer in which the dinosaur fossils are found, is that correct? This is the same reasoning that dates this newer meteorite find to an even older time period. There's plenty of empirical evidence here for a meteorite impact just to judge from what is reported, but here is no evidence for the geo timetable, the great ages, or for all the single separate events postulated on the basis of the geo timetable. There no evidence so far for the SIZE of this impact. Could be local to the Eastern Asia-Australia area of Pangaea.

Last link at post #1
"We know that meteors have struck the Earth hundreds of times," Ellwood said. "If I had to guess, I would say that once every 5 million years a meteor big enough to cause a mass extinction hits the Earth.
OK, this is the LSU article linked in post #1 and it's about this scientist who is interested in meteor hits in general and one that may have occurred in the Devonian, yet a different one from the KT boundary one and the Permian-Triassic one.
I guess I've done enough exploring of these articles.
Evidence of meteor impacts there is. But so far there is no certain evidence of the huge size of such hits or their supposed lethal effects. This is all extrapolated from the geo timeframe and the location of some meteorite chemicals in the layers. I would suggest there may be other more likely explanations.
In any case I'm here trying to defend my mere "thought" that the meteor events started with the Flood. So now I hope I will finally get to all the heavy science posts that have been piling up in the middle of this thread.

I just can't get a break, can I? The "photo" which I didn't examine in any detail, obviously, I assumed was from a recent event, obviously, and I wondered what event caused it. If you'd just think a little you'd save a lot of time and thread space.
Yes I am looking for deceit. That's because for years I accepted this kind of mind-twisting report. Now I don't let it get me, I aim to get it first.

Your local college bookstore
Your local college bookstore will sell freshman geology texts.
Mine is a fourth edition of 'Putman's Geology' by Larson and Birkeland. It is from 1982 and somewhat out of date, but covers the basics. The bookstore will have the more current copy or something comparable.
The book "The Map that Changed the World" is about Bill 'Strata' Smith and how he came to conclude great ages. I'm waiting for the copy in our local library to come back in.
And if Bill Birkeland reads this post perhaps he can tell us if he is related to Peter W. Birkeland who wrote my college text.

Re: timetable hilarity
Why is this hilarious? Why is it absurd? Why is it irrational?
Oh it just really really is. SUCH a joke. I wish you could see it.
Faith, I am not a scientist by any stretch of the imagination, but how can you expect any casual observer to take your position seriously if this is the quality of your arguments?
These guys know what they are talking about, some have studied the subject for decades, some of them are professional scientists, and you expect them to accept "Oh it just really is"?
Tell you what, I readily admit that I know very little about science, why don't you explain to me,in very simple language, why "it really just is."
Another thing, you have a chance to learn a lot from people here who have a great knowledge about the subject, they can help a lot, you just have to try being a bit more open-minded.
Brian.

Re: No one is lying nor is it easy to slip anything by.
Since in nature there usually aren't exact fits anywhere, the inevitable slippage is usually simply filled in with the prevailing theory. It's a reasonable enough thing to do, but other theoretical possibilities are kept from consideration by such a cognitive process.
There will be little value in your continuing this discussion with your current attitude.
Listen, this is my point of view, not my attitude. Since I am the butt of every kind of insult throughout this thread, you might have the decency to consider what I'm saying. I'm not even HAVING an attitude in the above, I'm explaining how I view the evidence, but YOUR attitude could sure give me one.
Oh "Slippage" ????? I am not accusing anybody of lying or slipping anything by anything. The "slippage" I'm referring to is between the known facts and the gaps in the physical record, areas where you don't know what's going on because there isn't any clear evidence, which is a pretty large area I would think. In such cases the theory fills in the gaps and I even SAID "it's a reasonable thing to do."
We are attempting to help you by summarising the evidence to an enormous degree. When you don't have ever detail you make any assumption at all that you can grasp at to suggest that there are flaws in the data or reasoning. The degree of summary necessary to be able to post here is enormous.
That is not a fair representation of anything I've said. I'm pursuing a definite point of view. I am identifying the difference between empirically substantiated claims and unsubstantiated claims, and I'd appreciate it if you would follow my argument. You don't have to agree with it, but if there is any real commitment and not just a pretense to allowing me to have a different point of view from yours, you can't keep dismissing mine on the basis of yours as you do. I'm using the evidence as it comes up. I've barely begun thanks to dozens of voices making nasty and mostly utterly irrelevant comments and you think it's over already.
As noted earlier it took years to convince the geologic comunity that the K-T extinction was clearly associated with an impactor. They did not accept any of this easily. The arguments went on for years. The amount of work done is very large indeed.
I don't think I've seen that post yet. I don't recall it. Too much going on. Nevertheless while that is interesting it is not relevant to my own concerns.
Today we still have arguments. I'm not aware of anyone that doesn't accept the impact idea but they do suggest things like "the dinosaurs were on their way out anyway" or "some survived a little past the event" or "vulcanism played a part too".
Fine. I'm sure there are many questions. But I'm also sure none of them question the time-frame view of the age of the dinosaurs and their extinction as a separate event from other extinctions and mass deaths in the fossil record, but that's MY question -- and my objection to the time-frame notion is that it is untestable and unfalsifiable, a decent scientific objection.
You have to either accept that there is, indeed, a very sharp (considering it has been awhile ) division at the K-T boundary or you will have to do a lot of work to learn enough to be able to reasonably critisize it or you may as well carry on believing what you now believe. If you pick the last option then don't pretend to have any scientific support for your views.
I accept the physical boundary. Haven't I made that clear? I don't accept the interpretation of that boundary, and I would think I've made that clear too. My arguments have been scientific, but obviously you will accept nothing as scientific except what validates the status quo theory.
You appear to simply refuse to allow me another point of view. I am not allowed to disagree with these major points. Then why the pretense of EvC to be "debating" anything whatever? You apparently see your role as merely to educate those who disagree with you. I don't see that in the title of the place, or in the Forum Rules.
The other thing that is simply solid now is that there was an impact at the K-T boundary. If you won't accept those then why are you bothering in this thread? You won't listen to anything you are told in any case.
I DISAGREE WITH SOME OF IT, AND I HAVEN'T YET BEEN ABLE TO READ THROUGH TO HALF OF IT.
The KT boundary is a (misnamed IMO) boundary between two layers of differing sediments. This is a factual empirical statement. If you disagree with it you are not being scientific. Iridium is apparently found between the two layers. This too is a factual empirical statement. The iridium suggests that there was a meteorite hit that caused the dispersion of this element. This too seems empirically justified.
However, you assume it was spread over a surface that was exposed for a long time. I think it was probably spread over a surface that was exposed for a very very short time, maybe as short as days. It may have been spread by water. THERE IS NOTHING IN PRINCIPLE UNSCIENTIFIC ABOUT THIS IDEA AND DISAGREEING WITH YOUR VIEW OR THE PREVAILING VIEWS HERE IS NOT THE DEFINITION OF UNSCIENTIFIC.

Re: Ok, all in one year
now imagine a 6-mile wide stone hurtling down into the water at terminal velocity, super-heated by the friction of the air. like ned said, the water may as well not even be there. in fact, i'll go a step further and say it wasn't, even if there was a flood. the fire and brimstone from the sky would have evaporated the water into steam before the rock even hit.
Could we please get something straight here. I'm not saying the water would have any effect in slowing the fall of the meteor, I'm saying that hitting deep underwater it isn't going to have the same aftereffects it would have if it hit on land, the huge dust cloud in the atmosphere all over the earth for instance. As for the fire effects, I'll have to wait until I get to the posts where that kind of effect is calculated.

Re: God tells all
So, Noah didn't mention the comet/meteor strikes to whoever wrote Genesis because he didn't actually see them? Then how did he know that the flood was worldwide? He couldn't see that either.
He didn't see the top of a mountain for an entire year. I don't know if he saw meteors or not.

Worse than ark soup: charred planet
we take the Impact Database and the impact effect calculator We can divide the craters into groups and estimate their impact energies. I did this with 120 or so that are more than 4 km in diameter, to 60 that 4-10, 25 that are 10-20 and so on. I then calculated the impact energy based on the smallest crater size of each division to get a rough estimate that underestimates rather than overestimates the energy.
What happens when these things hit in water? First they vaporize a massive amount of water putting steam in the air. Then they vaporize themselves and part of the earth's crust producing a massive heat and shock wave. The big ones will produce a fireball that will ignite wood 500 miles away. I calculate that the energy released is about 6 X 10^24 J equivalent to dropping about 1.5 billion 1 megaton H bombs. Thermal radiation, steam and vaporized rock are all efficient ways to transfer heat to the air. The earth's rate of heat loss by Black Body radiation won't be able to keep up and the atmosphere will heat up. The heat capacity of atmospheric gases is about 1 j/g-K and there are about 5 x 10^21 grams of gas. This means that enough heat is released to heat the entire atmosphere to 1000 degrees if it were all transfered to the atmosphere. Of course quite a bit of the energy will go into melting crustal rocks and into molten rock that falls back into the global oceans before giving up all its heat to the air. Still I think it would pretty thoroughly cook the earth to death.
Now realize that what we see are craters from only a small fraction of the objects that hit earth over its history. As mentioned before just look at the moon. The earth would surely have received many more hits than the moon during the lunar bombardment, probably being hit by dozens if not hundreds of objects from 20 to 100 or more km in diameter and thousands of smaller ones vaporizing the oceans.
I obviously can't answer your calculations. And I'm not sure I'm following you. Are you thinking about the number of hits in different places at different times and accumulating the effects together or are you just talking about the biggest one on the list? If this is just the calculation for a very big one then nothing could survive at all even under the extinction scenarios -- Life as such would have to start over. In which case, something must be wrong with your calculations.
But if you are taking all the known ones and calculating their effects over a short time span, that isn't clear from what you are saying. What if you calculate them over a year, a hundred years, a thousand years, 2000 etc? Instead of the usual millions/billions I mean. How does that affect the global impact picture?

The Flood
The Flood was not a miracle. It was a completely natural event
Didn`t someone point out if you can`t test, replicate or falsify a geological claim, it`s a load of hogwash? Oh, yeah
Thus does "science" proceed from bitty fact to gigantic theory to straightout claims of gigantic fact when it comes to past events that can't be tested, replicated or falsified, giving them carte blanche for the wildest of theories declared to be fact.
Can`t remember who kept repeating it over and over, but the expression 'too few facts, too much drama' rings a bell.
Hilarious.

The Flood has written testimony for evidence, the Geo Timeframe has zip. However, I don't claim that my theory has any more testability or falsifiability than the geo timeframe does. We are debating plausibilities. The point is there is no more genuine PHYSICAL proof of the geo timeframe than the Flood.
The Flood does, however, have the advantage in evidence because there is a written record of it.
Thus does "science" proceed from bitty fact to gigantic theory to straightout claims of gigantic fact when it comes to past events that can't be tested, replicated or falsified, giving them carte blanche for the wildest of theories declared to be fact.

Yup, that's exactly what I'm saying above. They start with a piece of rock found between two layers of sediment, and they conclude with a devastating meteor hit at a particular time with particular consequences. Bitty fact to gigantic theory, soon declared fact without the slightest justification. Meteor? Sure, no problem. Time frame? No evidence -- all untestable unfalsifiable conjecture. Particular extinction event? No evidence --all untestable unfalsifiable conjecture.

Its a 1000 degrees if all the heat went to the atmosphere. The fossil record indicates that life always come back after catastrophes. I suspect that protected areas (caves, deep sea rifts, or others) far from the impact area provided the retreat from which life resprung.
Some life called extremophiles can live in very harsh areas, so life is probably more resistant to these shocks than you think. But if all those impacts happened in that short period that you think massive tectonic movement also occurred, then I might agree that life couldn't survive. Great ages provides time for heat to dissipate, as major impacts happen millions of years apart as opposed to every day for a year or so, when crustal plates are running around the world and large mountains are springing up from flat land. That scenario makes no sense from a physical or geological POV.
