Concerning the Dendrochronology (tree ring) references, doesn't that require atmospheric calibration? After all, tree rings can grow differently based on atmospheric content, so since we now know ancient earth's atmosphere was different, with oxygen levels 50% higher than today's levels, how can we be sure oxygen levels at the time did not result for error?
Concerning Message 4, varves are said to represent millions of years, yet Josh McDowell and Don Stewart pointed out cases in "Reasons Skeptics Should Consider Christianity" where the evidence appears to indicate a much shorter time span. To quote from pg. 206 in the print version:
quote: Reasons skeptics should consider Christianity - CreationWiki, the encyclopedia of creation science It's on pages 205-207 online here: http://joshmcdowellmedia.org/...ouldConsiderChristianity.pdf This, though, is one clear case I know of where varves are assumed to indicate vast time spans under Gradualistic assumptions, yet evidence clearly indicates they were instantly fossilized. Otherwise, the flesh outlines wouldn't be visible, they wouldn't have been fossilized at all (depositional rates would be far too slow), there would be a thicker layer of mud, and the fish would not be pressed flat as they are. Concerning the ice layers, they are trying to calibrate for atmospheric levels even though we now recognize oxygen levels resulted in such massive life of ages past because they were far higher: http://news.nationalgeographic.com/...oxygen-animals-scienceMore Oxygen Could Make Giant Bugs | Live Science http://news.nationalgeographic.com/...730-giant-insects.html Recently, we discovered fossilized raindrops show earth's atmosphere was much thicker as well. Splat Science: Fossilized Raindrops Reveal Early Earth's Hazy Skies | Live Science I guess I'm a little skeptical given the growing evidence that earth's atmosphere was far different, that they can reasonably assume it was the same as today's prior to such catastrophes. Why are they so convinced the atmospheric calibration is reliable? Edited by Jzyehoshua, : No reason given. Edited by Jzyehoshua, : No reason given. Edited by Jzyehoshua, : No reason given.

Essentially, per my other reply here (point 9), the dating methodologies revolve around the assumptions of Uniformitarianism, Gradualism, that everything went at one rate - even though this assumption contradicts Microevolutionary Rates today and the evidence of stasis and lack of transitional forms that led to the theory of Punctuated Equilibrium. Furthermore, the theory of Uniformitarianism replaced the theory of Catastrophism, yet today we recognize Catastrophism was correct.
EvC Forum: Professional Debate: Scientific Evidence for/against Evolution Any Takers? Radiometric dating depends on Uniformitarianism as invented by Lyell. But Lyell recognized what would happen to his theory were Catastrophism shown correct, along with rapid speciation after catastrophes. He privately expressed concern to Darwin in 1844, stating:
quote: The fear Lyell expressed has been shown well-founded. Today we recognize mass catastrophes did occur. We also can see from the fossil record that it is not consistent with Gradualism, which led to Punctuated Equilibrium. Yet scientists want to pick and choose, assuming "the present is the key to the past" concerning isotopic decay, under the presumptions of Uniformitarianism - even though it failed to pass the tests of falsifiability, and the original theory of Catastrophism has shown itself correct.

Even supposing that that was true, which it isn't, what could that conceivably have to do with the constancy of decay rates, which are, y'know, something else? It's like saying: "People think that mice are small. But this is contradicted by observing that elephants are big". The evidence for constant decay rates, and the evidence for the size of mice, depends on the study of decay rates and mice respectively. The constancy of decay rates depends on the assumptions of Uniformitarianism, that slow, steady, and generally unaltered processes were at work. Scientists assume decay rates were constant for no other reason than that Uniformitarianism is their accepted theory. Is there any particularly good reason for it? Not really. We know isotopic decay rates can be altered, but Brent Dalrymple in "The Age of the Earth" argues that such alterations are rare and minimal. But ultimately we just don't really know. We don't have a time machine. And the more we find out, the more the fossil record disagrees with a Gradualistic, Uniformitarianistic view. Oxygen levels were far different. Catastrophes did occur. There were no transitions indicative of Macroevolution, and if you start hypothesizing that evolution suddenly sped up per Punctuated Equilibrium, then you have to explain why you assume isotope decay rates couldn't have also sped up. Plus the new recognition mass catastrophes did result in ancient mass extinctions increasingly raises the question of why those catastrophes didn't affect the amounts of the initial daughter isotopes, atmospheric isotope levels, or isotopic decay rates - WHICH ALL HAD TO REMAIN CONSTANT OR PREDICTABLE TO REACH RADIOMETRIC DATING RESULTS. Everything for Evolutionary Theory is pretty much built like a stack of cards on the presumptions of radiometric dating by this point, which in turn is based on Gradualism and Uniformitarianism. And radiometric dating requires assuming that decay rates were unaltered or else predictably calibrated over millions and billions of years. If the system wasn't closed with isotope levels changing, if the isotope decay rates altered in speed, if the atmospheric isotope levels were different from today's, you would get the results thrown off. And a mass catastrophe involving intense water or volcanism could do that. Forces within the earth like heat or magnetism might as well.

One I've never heard considered before is whether the electron shield that insulates isotope nuclei from decay could itself have grown in strength. Dalrymple in "The Age of the Earth", the section on Radiometric Dating, states this shield prevents all but extreme forces like nuclear reactions from altering nuclei. He assumes as such that the nuclei weren't substantially or commonly affected in decay over such long time spans as a result.
Trouble is, if the electron shield itself evolved, that whole theory goes right out the window. I suppose they won't consider the possibility, however, unless we somehow come across strong proof that this occurs. For me it remains a serious question mark as well though. What really bugs me, frankly, is this is all being passed off as undeniable fact. Yet we still don't even know how radioactive decay works as a process, at least at the time of Dalrymple's book when he admitted it. There really hasn't been much understanding of the principles of radiometric dating and a lot of this stuff is just now being delved into and presented to the public. The investigation is still very much underway to prove this, in other words, and here they are trying to shout down opposing views as ignorant, like it's proven beyond a shadow of a doubt. I can clearly see that's not the case at all. Edited by Jzyehoshua, : No reason given.

No. Belief in the constancy of decay rates is built on the evidence that decay rates are constant. What evidence do you think there is that decay rates are constant?
"If you start hypothesizing that elephants are big, you have to explain why you assume that mice are small". A better quote would be, "If you start hypothesizing that elephants are big, you have to explain why you assume that SUVs are not big. You Evolutionists are assuming Evolutionary Rates could speed up under Punctuated Equilibrium, but don't want to accept that isotope decay rates could have sped up. On the one hand you say the present is the key to the past and assume isotope decay rates were the same as today's. But on the other hand when today's rates are too fast to allow an ancient earth (which Microevolution rates are per here) you assume today's have sped up for some reason. And when the fossil record shows stasis and lack of transitions rather than gradual transitions, you assume evolution suddenly sped up in the past and didn't show up in the fossil record, per Punctuated Equilibrium. You want to say one had to remain constant and say the other situations were variable, just whatever will make Evolutionary Theory work, in other words. To me it looks inconsistent.

Uhhhh......"nuclear reactions" are what make nuclei decay. Electron capture and beta decay rates can be affected by things like stripping the electron shell off of an atom, but alpha decay (like in uranium dating) not so much. And I'm betting that your "shield" would affect the rates of alpha and beta processes in opposite directions, anyway. Where are our physicists?

Please don't go off topic with more extraneous distractions. You need to show how this affects the correlations, otherwise all you are doing is throwing sand against the wall to see what sticks. The constancy of Uniformitarianism is acknowledged here on this University of Tennessee page, and its presumptions as central to Dendrochronology: http://web.utk.edu/~grissino/principles.htm
quote: However, the whole dating methodology revolves around the final sentence, the "assum[ption] that conditions must have been similar in the past". As seen from the page, to definitely prove the method, you must first prove conclusively the assumptions upon which the method is based, namely: (a) Rings had to have indicated one-year periods each time, and could not have grown faster.(b) Trees can be effectively cross-matched. (c) Trends regarding precipitation and other data are being effectively derived and not mistakenly assuming based on current circumstances. Look, this has always struck me as a pretty esoteric, arcane attempt at fringe 'science' for which there's been a dearth of reliable information. Many of your early sources no longer work meaning I have to do entirely new searches to cross-check some of your points. And Evolution has a long history of selectively interpreting evidence to result in bias, like with Peking Man or Lucy (which we just recognized recently walked upright after all unlike the original press announcements). For me to decide this is solid methodology I need to understand why they are so sure rings represented the exact amounts of times claimed. Is there a source for your claim that they represent just one year each? How can this be sure? So much seems likely to rest on this and the ability to cross-check reliably between trees. I understand the concept, look for evidence of droughts or fires that show up across multiple trees. But I'm also concerned a biased researcher could just selectively interpret two trees with different droughts as being cross-checked dishonestly. It could too easily be open to interpretation (like the fossil record or phylogenetic trees which are VERY speculative). I'm used to seeing shoddy research from Evolutionists with 90% speculation to 10% fact and I'm not going to easily accept this situation is different.

That they don't change. And scientists from the Curies on have tried to get them to change --- they tried heating them, pressurizing them, combining them in different molecules and so forth; they didn't just assume that the rates were constant, they did everything they could think of to make 'em change. And short of throwing radioisotopes into a nuclear reactor or something, the decay rates do seem to be very stable. Of course they change. Dalrymple in "The Age of the Earth" acknowledges they change. Volcanism and Beryllium both throw off decay rates. Dalrymple acknowledged they can change, just argued such changes are rare and minute. Lava from Mt. St. Helens for example was dated as hundreds of thousands of years old. Mt. Ngauruhoe's eruption resulted in dating results of 3.5 million years, and both were recent events. The ability for volcanic ash to throw off isotopic decay rates has long been a major point for Creationists:

Trees growing in climates with seasons - Winter, Spring, Summer, Autumn - grow in the spring and are dormant in winter. It's quite easy to understand. Dendrochronology - WikipediaBut your task here is not to nitpick methods but to explain why they all corroborate each other. Doesn't that assume seasonal fluctuation consistent with today's? We now know earth was once far more tropical than it is today (source below) so why is it assumed tree rings grew at the same rates? This assumption the present is the key to the past, that we can simply assume the way it is is the way it always was, seems to me a very dangerous fallacy.

The RATE team, with over a million dollars of creationist money, set out to prove that decay constants weren't constant. They failed. Read a summary of the results below: Assessing the RATE Project: Essay Review by Randy Isaac:Assessing the RATE Project Do the RATE Findings Negate Mainstream Science?:http://184.173.80.159/...RATEFindingsNegateMainstreamScience I'm always skeptical of a page that quotes a source and then doesn't give a citation link. I checked your ASA page and saw he was claiming the fission tracks in Zircons were acknowledged to show 500 million years worth of radioactive decay. So I hunted down the report for myself just now and double-checked. Turns out Mr. Randy Isaac took the quote entirely out of context when he said,
quote: Here are the ICR sources for the report itself: Radioisotopes and the Age of the Earth, Volume II | The Institute for Creation ResearchFission Tracks in Zircons: Evidence for Abundant Nuclear Decay | The Institute for Creation Research http://www.icr.org/...echnical/Fission-Tracks-in-Zircons.pdf The last is the report PDF including the quote itself. Here's the full quote, in context:
quote: That's the complete opposite of what Randy Isaac said the report concluded. To me that looks pretty dishonest to misinterpret the report like that. You really should double-check these assertions from now on because that's a pretty good example of dishonest misinterpretation of a paper right there. Edited by Jzyehoshua, : No reason given.

You're deflecting. If you want to discuss tree rings start a new thread - your task here is to explain why all the different methods of dating agree with each other. If they are ALL wrong, why do they agree? Is it a coincidence that all the dating methods are in error for diferent reasons but yet miraculously still agree with each other? Thanks for pointing out I was getting off-topic. I should've read more carefully to recognize that was the main topic and not just the methods themselves, my apologies. Concerning this point in particular though, first of all, do they really all agree with one another apart from indicating a minimum age to life on earth? And if not, then that just suggests scientists are trying to find any method they can to indicate an ancient date to life on earth. Brent Dalrymple points out a number of previous attempts that got debunked in "The Age of the Earth", the section on early attempts at dating the earth. They consistently failed because of (A) a belief in constancy per Uniformitarianism, and (B) inadequate consideration of all possible factors. Examples include De Maillet's theory on sea decline, Kelvin's theory on cooling of the earth and sun, and George Darwin's moon origin theory. It's online here starting at page 25: The Age of the Earth - G. Brent Dalrymple - Google Books Secondly, everything basically falls into 3 categories that I can see: (1) Radiometric isotope dating (Message 11).(2) Dendrochronology (Message 2, 3, 4, 5) and coral dating (Message 10). (3) Depositional rates (Message 6, 7, 8, 9). Why all 3 would be thrown off though is pretty easy to explain via a global Flood and previous canopy surrounding the earth, both of which are well-evidenced in the fossil record. We know ancient life was simultaneously extinguished although scientists dislike considering a Flood was involved, and prefer to hypothesize about meteor impacts or underwater volcanoes. They assume multiple huge catastrophes like the Permian-Triassic extinction event, Devonian extinction, Ordovician-Silurian extinction, Cretaceous extinction event, Triassic-Jurassic extinction, and Pre-Cambrian mass extinction event.Catastrophism - CreationWiki, the encyclopedia of creation science Mass extinction facts and information from National Geographic We also know earth's atmosphere was once much thicker than it is today, and that oxygen levels were 50% higher resulting in huge insects in earth's past.Canopy theory - CreationWiki, the encyclopedia of creation science A Pre-Flood Canopy would result in higher oxygen levels and initial daughter isotope levels, affecting both radiometric dating and dendrochronology. The Flood itself should affect radiometric dating and depositional rates especially. As I pointed out in Message 93, there appears evidence that the sediment layers were not laid down over long periods but rather by a massive Flood at one point (Point 3, Message 6, 7, 8, 9). And such a Flood would alter isotope decay rates as well, especially if volcanic activity was involved. It would fossilize pretty much everything at once and lay down multiple layers of sediment in a short amount of time - layers scientists today assume were laid down gradually over long periods. In summary, I think the combined explanation of a Pre-Flood Canopy coupled with a global Flood serves to explain why all 3 dating methods would be substantially altered to account for a recent date to life on earth.

The Biblical Flood has been totally and completely refuted as has any absurd vapor canopy. Either are simply non starters and covered in other threads. They would be irrelevant in this thread even if they were true. Well, the thread asked for an answer and that's the answer, both Biblically and as I see it from scientific evidence. If the thread wants to consider them inadequate so be it, but that appears the logical Biblical theory for why all 3 methods would be thrown off from a Creationist's standpoint - I doubt you'll hear any other theories. It would explain why geologic layers worldwide were laid down rapidly at once and thus geologic dating was caused by a Flood at once. Ice cores were likely the end result of the Flood as well, and caused instantaneously rather than the result of slow, gradual processes. It would explain why fossilization has occurred worldwide, an improbability given that depositional rates are too minimal to fossilize anything. You need to cover something very rapidly to prevent bacteria/scavengers and erosive forces from destroying it so it can be fossilized. It would explain why fossilized footprints exist in sandstone and even fossilized raindrops, showing the fossilization was instant.Reasons skeptics should consider Christianity - CreationWiki, the encyclopedia of creation science It would explain the mixing of fossil deposits with animals and plants from all climate zones worldwide, a point made in 'Reasons Skeptics Should Consider Christianity'. That's not something that makes sense under other theories but a global Flood.Reasons skeptics should consider Christianity - CreationWiki, the encyclopedia of creation science It would explain stasis in the fossil record and lack of transitions that led to Punctuated Equilibrium being hypothesized.Punctuated equilibrium - CreationWiki, the encyclopedia of creation science It would explain why the human-apes theory has fallen apart over the past decade:Transitional form - CreationWiki, the encyclopedia of creation science To me this appears a theory I can't easily debunk and to my mind is a better fit with all the evidence I see than Evolutionary Theory. To me it is more reasonable than Evolution from a logical standpoint since Evolution can't account for a number of otherwise puzzling factors. Edited by Jzyehoshua, : No reason given.

Too bad for you then that the Biblical Flood never happened. So far as I'm concerned, Macroevolution never happened. It's a myth that was always pure speculation interpreted by the minds of some philosophers who labeled it science and instituted it in law before it was ever proven. They've been trying to persuade everyone their pet theory is science ever since then. Despite their best attempts 40-50% of Americans remain unconvinced over a century later. I see better evidence for core created species than a common ancestor given the fossil record, sterility in interspeciary breeding, and rapid microevolutionary rates. EDIT: I just saw your mention of the other thread and will take a look at it, thanks. Edited by Jzyehoshua, : No reason given.

quote: (1) I just explained in Message 124 how all your points fall into 3 categories, Dendrochronology, Radiometric Dating, and Depositional Rates, and are explainable through a Pre-Flood Canopy and Global Flood.(2) Concerning the Dendrochronologies, the oldest tree we have dates under 5,000 years. And that's assuming rings were dated correctly at a year apiece. The cross-dating becomes speculative as it depends on their correct analysis of a pattern existing. According to your Message 2: quote: Obviously if they just pick and choose 2 similar rings for two 4,000 year old trees they can claim trees of similar ages show a 7,000 or 8,000 year history, even if the trees grew at approximately the same time. Their analysis needs to be double-checked to show the pattern was indeed reliable.

It assumes that the earths tilt and orbit produce seasons, just as they do today. Of course if you have a mechanism to alter the tilt and orbit without it showing up in the tree ring chronologies, then please provide your hypothesis and the evidence for it ... otherwise you are just throwing mud, not debating the scientific validity of the correlations. You still haven't addressed my Message 124 which did provide the mechanism you and others wanted. I still see no reply to my explanation of why correlations would exist.
You have not explained the correlations between four independent dendrochronologies in different global locations, in different ecologies and in different species of trees ... a correlation within 0.5% for 8,000 plus years. I just explained that in my previous post.
