https://answersingenesis.org/geology/radiometric-dating/radiometric-dating-problems-with-the-assumptions/. I came across this article about radiometric dating. It's on a Creationist website so there may or may not be some bias. I wanted to make this an unbiased research project so I am inviting people from a variety of different schools of thought. Atheists agnostics, deists and Creationists are invited to do a research paper on the following questions:

I read the study from Princeton. I find it interesting that it says that zircon crystalyzation occurs during magma events (volcanoes). This it doesn't protect the specimen until it is being erupted which would be after the damage of fission decay have already taken their toll. This could lead to an interesting experiment that could prove my theory. In order to for the results to be verified, I would want a double blind study done.

SPC Nathan Freeman, how would damage occur to the crystal before the crystal formed? The crystal doesn't form around a specimen, the crystal itself IS the specimen...

And remember from earlier (and the paper), if you had an old crystal with sufficient radiation damage that it was no longer a "closed system", it would indicate an excessively young age due to lead loss, as opposed to registering as older than it really is. Having new crystal form around the older, damaged one, would effectively only serve to start the clock at the new point. The crystal would indicate younger than it actually is, playing into the biases of creationists. And despite so many opportunities for a crystal to become damaged and indicate an excessively young age, we still abundantly find ones that indicate they are billions of years old.

Also, magma is the term for molten rock when it's underground. Once it erupts it's referred to as lava. This is why the paper discusses the problem of significant percentages of zircons in a sample being older than the others, or being older than the rock/ash they're embedded in. Zircons can form anytime while they're underground in a magma chamber or whatever, up to and during eruptions. If a crystal forms 1 billion years before it gets erupted, then it will be 1 billion years older than the rock it's in. And because more crystal can form around an original crystal at any time up to and during eruption, the core of a crystal is older than the outer parts. They discuss all that to explain why it's important to take a lot of samples, and determine the age of different parts of crystals, so they can find the youngest ages (which would be most associated with the eruption time).

I find it interesting that when they find a sample that indicates a young age, they assume there must be an error and this discard it. They listed a dozen ways you can have errors and toward the end they mentioned that zircon dating is in it's infancy.

The problem I was stating is that the accelerated aging of Ur would occur during a fission or fusion process before the zircon coating. Another article I read which will be in the paper suggests that the earth might have a fusion process in the core which would be another confounding variable. It is likely that the reason the are getting such a variation of readings is that fission and fusion are recycling some of the lesser elements while accelerating the decay of Ur. (If there is fusion, it wouldn't be powerful enough to make Uranium but it would certainly break it down at an accelerated rate). Uranium and plutonium in the core would power the fusion reaction. I need to study more on nuclear fusion/ fission to see what the rate is in a reactor and if there's empirical evidence of different rates observed in nature.

SPC Nathan Freeman ???? We already covered the fact that decay rates are constants, and that external forces do not affect those rates. We get a variation of ages of zircon crystals because some are older and some are newer. And uranium and plutonium don't power fusion reactions, they power fission reactions. FYI, fission is the purposeful splitting of atoms by shooting neutrons at them, whereas decay is the natural breaking up of an atom. The rate of fission in a reactor is very controlled, results in different isotopes than decay, and requires a different isotope of U (235) than we use for dating

What paper is this about fusion in the core? The current understanding is that there is no fusion occurring in the core, because there is not nearly enough pressure/heat to facilitate it (i.e. overcome the Coulomb Barrier). Even massive Jupiter doesn't have fusion occurring inside it, fusion only happens in stars and thermonuclear bombs. I can't find anything on the internet confirming fusion in the Earth's core. Fission is another story though: http://www.nature.com/news/2008/080515/full/news.2008.822.html

The only "erroneously young" samples they discarded are ones with so much radiation damage that lead has leeched out, which they did away with before even testing them. And in cases where there was too much radiation damage in the outer layers but not the core, they'd shave those down to get at the center. They didn't get the age, assume a bad crystal, and then discard. They determined whether a crystal was bad before testing/knowing its age. And remember "young" for these guys was on the order of magnitude of 1-10 million years too young, in the context of overall sample ages of hundreds of millions of years and older.

Yes, they listed all the ways you can have errors (erring younger AND older), and discussed all the ways these errors are identified and mitigated. And no, they mentioned U-Pb dating, as applied to stratigraphy in particular, is a relatively new thing. The dating technique itself is not new at all, it's been around for decades. This is just towards the beginning of using it in conjunction with studying rock layering (stratigraphy). Infancy nonetheless, they boast accuracy of a tenth of a percent.

Nevermind once again, that decay rates are constants: if the Uranium to be captured had already aged (i.e. become a completely different element), before becoming part of a zircon crystal (not coated by it, they become part of the crystalline structure, via occasionally substituting for zirconium)...it would not have become part of the zircon crystal to begin with. Uranium atoms in particular can substitute for zirconium atoms in the crystal structure, the daughter isotopes can't. This is why there is radiation damage when the U decays: because the new element it has become doesn't "fit" in the crystal structure, and yet the atom cannot escape, the structure in that isolated area will fracture. So if uranium decayed before a crystal started forming near it, then being that it is no longer uranium, it will not get incorporated into the newly forming crystal.

SPC Nathan Freeman -- Did you really say "there may or may not be some bias" on a Creationist website? I don't think it's possible to be any more biased!

That doesn't mean I disagree with your linked source.

Assumptions are actually what got me to question evolution in the first place. I grew up believing in evolution. I grew up in utter fascination with a Time/Life book on the earth's origins my grandmother had at her house. But the assumptions...

The beginning of the end for me was the question, "How do they know that?" I became a creationist long before I ever became a practicing Christian. Ultimately, I believe that is why evolutionists are so invested in the idea of evolution -- they don't want to deal with the implication that there might be a creator, because then they might have to be accountable to someone greater than themselves, so they glom onto the theory which makes it not necessary.

The problem with that approach is it leads to crappy science. People accept absurd ideas and use inane reasoning, even if the science points in the other direction. Evolutionists make fun of the church in the middle ages (and rightly so IMO) for being the self-appointed arbiters of all knowledge & truth and suppressors of contrary viewpoints, yet this is exactly the role they have placed themselves in over the last couple of centuries.

The conflicting data regarding dating is exactly the kind of thing that is not addressed in schools, even though it is a perfectly legitimate science topic. Why? Because questioning the legitimacy of data impedes the indoctrination process. Evolutionists don't want people asking those types of questions until long after the people asking them have completely sold out to evolution. (They'd prefer people not asking such questions ever, but some people just don't follow the script. I submit myself as an example.)

Regarding the dates of rocks, I think it is pretty self evident that the layers of rock on top of a stack of strata should be younger than the layers of rock on the bottom. When the radiometric dating shows otherwise, it is either disregarded and hidden, or explained away by "overthrust" (regardless of whether there is any other supporting evidence for such overthrust).

As an addition to SGT James Elphick , proof that speciation does not occur would falsify evolution. Evidence that rabbits existed 3 million years ago in their present forms would falsify evolution. I say this only to illustrate that evolution is some immutable doctrine. Evolution (which happens) as it is currently understood (called the theory of evolution) isn't some competing religion. It's a model of the universe. You propose no alternative.

see you later, Mr. Brose.

SGT James Elphick Fair point about the end of the OP's linked article. I would not have worded my conclusion that way, but in fairness, I think that article was intended only for a Christian audience. I'm pretty sure if he was addressing a mixed crowd or specifically addressing people who believe in evolution, his conclusion would probably have read quite differently. My entire approach in these discussions is to avoid any theological specifics, because really, the only relevant part is the bit about a creator/intelligence. Looking at the science and seeing evidence of intelligent design is not necessarily going to point to a specific creator. That is a separate question, and needs to be addressed separately.

Your statement that even non-beneficial mutations are evidence of evolution at work is a statement of rather profound faith, and it actually misses the point of evolution altogether. As a concept, evolution is not based on the idea that the current stable species will out-survive the non-beneficially mutated versions of itself. It is based on the idea that something new will develop and replicate and out-survive the current stable species.

What do we actually see in the world around us? The mutated versions of complex organisms die far earlier than the non-mutated versions. What do evolutionists conclude? All mutations are evidence of evolution at work. I hope you realize just how much religious-type faith is involved in that belief.

The basic premise of evolution has not proven to hold true. Everywhere you look on this planet, you see stability within a set genetic range. That range can be quite wide in some cases, like dogs and cats, and to a lesser extent humans. Variations within that inherent genetic range are not mutations. And when there are mutations, those mutations almost universally have a negative impact on the mutated individual's ability to survive. (I say "almost" to be generous.)

Humans have the benefit of hospitals, and some animals have the benefit of veterinary care. That reduces the impact of survival-of-the-fittest, and so many people with mutations who would otherwise die a lot sooner are able to live happier, healthier lives. But in a naturalistic sense, the healthiest people, the ones most likely to survive and thrive and reproduce, are the least mutated ones. And for those wanting empirical evidence, that is completely empirical, observable, and verifiable.

The fossil record is another area of study where, like with dating methods (and for the same reasons), inconsistencies are never mentioned in school, and preferably never mentioned at all. It would detract from the image of a nice, neat, consistent, scientifically proven image of evolution. But really, it is an area where the desire to prove evolution has resulted in accidental misinterpretations, deliberate misinterpretations, and outright fraud. Of course, that happens in all areas of life, so it's not anything peculiar to evolutionary circles -- but the fact that it doesn't get discussed in school leads to the common perception that the fossil record unquestionably supports evolution 100%. Like most other things, it only supports evolution 100% when the person doing the interpreting tries really hard to make it support evolution 100%, and ignores the inconvenient stuff.

Damn! SPC (Join to see) I am trying to read your "wall of text" because I wanted to respond to it, but for some reason, the site won't show the whole thing to me, and doesn't give me the [see more] option. I tried in Google Chrome and Mozilla Firefox, and neither one will let me see it, so I'm guessing it has something to do with the site. I hate to do this, but could you repost it? Or if someone has the magic formula that lets me see into the past on this site, that will do as well.

Doh! Never mind. Something about posting this post unlocked all the others, so now I can read it all. Response will follow.

a small point before I get started. "As a concept, evolution is not based on the idea that the current stable species will out-survive the non-beneficially mutated versions of itself. It is based on the idea that something new will develop and replicate and out-survive the current stable species. " Could be both, or neither. segments of the population that develop characteristics randomly that seem to allow that segment to reproduce more successfully than the rest will see those genes/attributes become more widely distributed within the whole population.

"inconsistencies are never mentioned in school, and preferably never mentioned at all." If you're talking about high school, you're mostly correct. But this is not so at universities. Are where the magic of science really happen. That's the fun stuff. What happens inside black holes? How do we/should we fight viruses? In the past it was: What the hell is lightening, anyway? Why does molten rock spew out of mountains sometimes?

I think a lot of what you and I are talking about can be smoothed out by speaking more clearly. Evolution, change over time, happens. It is self-evident, but doesn't need to be taken for granted or on faith. These changes are observable when parents have children, dogs and horses are bread, etc. We are not exact copies, I think you agree. Evolution commonly is also thought of as speciation, or when a segment of the population of an organism is incapable of reproducing with a similar organism-population who share a direct descendant. (macro, micro, it's really all the same. the difference is usually attribute-able to either time or geography)

The 'theory of evolution' is an attempt by scientists to understand this basic observation, and explore its workings as well as its outcomes. By taking evidence gained thorough multiple specialties of scientific study, namely medicine, genetics, paleontology, taxonomy (just a few of my favorites), an overall picture can be formed that links all of these disciplines under a common understanding. This understanding is less flawed and incomplete as the individual studies themselves because it incorporates research from all of these disciplines. The really cool thing about 'the theory of evolution' is that it has also been around quite a long time, and is better understood than a lot of fields of studies most people take as common knowledge like gravitational theory and germ theory.

In fact, the theory of evolution sparked new areas of study, and has itself evolved :P to incorporate new evidence. It's not magic, or some doctrine anyone, ESPECIALLY scientists, are stuck with. It's a natural outgrowth of our understanding of the universe. It could be wrong, like any theory. It's definitely incomplete, and there's debate today. genetic drift, punctuated equilibrium, etc. But ignorance in one are doesn't belie empirical observations already made.

The really cool thing is you don't have to take ANYTHING on faith. Science only works on one assumption: that the universe is capable of being understood at all. Beyond that, anything goes. It might go quicker if you assume people are right, but the only right way is to verify yourself. That's what scientists do.

If you'd like references for any of these claims I'm making, just leave a quick response, and I'll get back to you at COB today.

Here's my first impression of the webpage. This will likely be a fun forum and I look forward to the results. Hopefully, my jobs won't be too time-consuming.

Anyway, all of the observations seem to be accurate, and come from reputable scientific journals, which presumably means someone will, or already has, confirmed the results of the observations. We can't really tell, because the website lists none of these sources, only the analyses of these observations by admittedly creationist authors. Does this mean they are necessarily incorrect? No. But I doubt any material that doesn't properly list its sources. I have access to a couple of the journals collected works, and for the ones I don't, I have friends attending nearby universities that likely would help me out.

I won't be an authority on the subject without years of study, and can contribute very little on a discussion on the efficacy of radiometric dating (You've seen how many dating methods there are, right?). I will say that scientists aren't ignoring these results, like 'contamination' in samples from seabeds, radiometric dating does require an understanding of the environmental forces at work. But it seems you wish to discuss the "Constant Decay Rate" problem specifically.

Sure, let me run out and take a few classes on advance calculus and quantum physics. Be right back.
