Critically, geologically, I found that in each of the mines which had NO RADIOACTIVES, there were _no_halos_ of -any- type. Radioactives:halos-in-the-mica::NO radioactives:NO halos-in-the-mica. > Apart from all other "secondary source" arguments, if this relationship holds across many mines and many locations, it would be obvious that for halos to be present at all, there _must_be_ nearby radioactive substances in the minerals, the pegmatite, the mine, or the local area, hence all halos must be sourced ultimately in the presence of generative radioactives, and the "secondary source" argument re:the local samples would become moot. Well, I suppose it is interesting to note that the Po halos only appear in proximity to U or Th lodes. But what does that mean exactly? I see you attempting to make a causal relationship between the two, and the correlation is indeed I would consider the correlation to be philosophically damning of Gentry's fundamental position, IF such a relationship were to become established. (We need not do the "all crows are black/no crows are white" philosophical thingie here )*grin*(.) But as I noted, the only data existing on this so far, is mine, and it's not enough by a LONG shot. For _me_, the relationship is established, and in this manner: I have enough direct experience with these mines that I can make the scientific prediction: "no point-source pleochroic halos (of _any_ sort) will ever be found apart from the 'close' presence of radioactive minerals." For me, that's the "standing hypothesis," since that's what my own data show. Another researcher, (or myself, if I go back to feldspar/mica mine-raiding), might find the example that breaks this proposed rule, and that would falsify this particular prediction of mine. I don't think it's going to happen. If not, that presents the _theological_ question as to why God would make it LOOK LIKE the halos were in all cases and everywhere descended from radioactives, and none at all were ever "made by FIAT" in completely unradioactive-bearing mica elsewhere, in an _unambiguous_ demonstration that "He Did It." The creationists want to use this phenomenon to "prove," if possible, that God DID "do it," but the evidence does NOT allow ONLY that interpretation. So long as for _every_ creationist explanation there's an "ordinary scientific" one, and for every ordinary scientific explanation there's a creationist one, and _no_way_to_mount_ a differentiating experiment, this argument cannot fall one way OR the other. _I_, at least, have proposed ways of telling whether Gentry's and/or my "polonium" halos are 218Po-caused, or 222Rn-caused, and until these tests or ones equally definitive can be mounted (preferably upon _Gentry's_ own samples, since he's the one with the 'extraordinary claim'), there's going to be no resolution, no matter how convincing I, or any opposing creationist, can textually be striking. What you're saying is that, because of this correlation, the Po which formed the halos are secondarily derived from decaying U-238, since U-238 is also always found nearby. We can _assume_ this, for the sake of argument, but what I am actually saying is that NO halos--of ANY kind, polonium, uranium, thorium or otherwise, can be formed in biotite (or any other mineral) which came from mineral sources (pegmatites, granite, what-you- please) that are known by professionals clearly NOT to possess any radioactive substances. The conclusion that parentless Po halos had to form secondarily is the _trivial_ aspect of this. The _primary_ aspect is as noted. you what...I'll agree 100% that you are correct. The Po isotopes which caused the halos are all products of the U-238 decay. But that still leaves you wondering how they got there. I hope you've been reading my posts in which I detail how Gentry's studies have shown that, in the sample he studied at least, radon diffusion could not have been the source for the polonium. I have been waiting for a page cite (to _C_T_M_ or one of his papers), so's I can find what-the-hey you're talking about.... I do know that, from my own readings of his papers and his book (_C_T_M_), there was NO effort on his part to refute my specific style of "diffusion" hypothesis. I can recall not a single word about _one-at-a-time_ radon- atom diffusion along cracks and separations, or about the idea that over vast amounts of time these atoms can repeatedly get themselves 'stopped' and/or 'delayed in transit' by changes in the shapes and diameters of the aforementioned cracks and separations. I have the _evidence_ of this, sir, in photos, notes and drawings of some of my carefully- labelled mineralogical samples. Gentry had NO WAY to tell whether or not he was looking down through _separated_ crystal planes, or through still-tightly-bonded biotite 'leaves.' An unbroken _leaf_ does not show a crack; neither does a _separated_ leaf, far as I can tell. That is: _show_me_ where Gentry refutes, deals with, dismisses, or even _mentions_ MY PARTICULAR VERSION of this radon diffusion idea, please? Please note, though, while we pass this above, that the 222 Rn hypothesis has yet another uniquely satifying aspect: this process is _self- driven_. The radon atoms do not _require_ themselves to be pushed around by gross outside forces, other than the thermodynamically random jiggling and vibrating of the walls of the crack or the "ceiling" and "floor" of a biotite crystal plane-separation. The process would logically work as easily in _air_ within the rock mass, as in water flowing or standing therein. "Hydro" is irrelevant to the workability of my hypothesis. (*grin*) Additionally, review your Gas Laws, and decide for yourself if the forces that provide the statistical character of the Gas Laws have aspects derived from the _atoms_ of the gas, and thus, whether or not there's such a thing as "gas pressure" in a closed tube with only, say, a few to half-a-dozen atoms in it. Where the _radon_ goes, in my 222 Rn-migration hypothesis, is NOT dependent on where the air or water goes in the rock mass (pegmatite). It is dependent only on three things: 1) the presence of itself, being constantly renewed at a more-or-less constant rate, 2) the _shape_ of the space(s) that it finds itself in, and 3) the temperature of the enclosing mineral (how much "vibrating" the walls of the space(s) is(are) doing, at local ground temperature). I have seen _no_mention_, in any of Gentry's writings on the Po halos, of this mostly "self-driving" mechanism. However, I have said that I agree that the Po that made the halos was a product of the U-238 decay. How would I explain it? This didn't happen until the third day. So at the end of this first day, we have an earth, but it is without form. One could say that even before the first day, when God created the earth, there was U-238 present. Between the creation of the earth before the first day, and the creation of land on the third day, the U-238 would have had ample opportunity to decay, such that when God did create "dry land", You will obviously have to decide that God did not make the "Laws of Physics" until _after_ this time, since 238U has an extremely LONG half- life, and hence, there would _definitely_ not have been enough time (in only three or so _days_) for decays from it to have passed through the first four decays-per-atom, let alone to have made any 500-million-alpha-hits visible halos--'polonium' or otherwise. IN fact, Gentry makes this creatiuonist-necessary artificial assumption- -several times. Wherever he needs a temporally-uncertain or temporally- anomalous period, he has God make one, which Gentry calls a "singularity." (Zero scientific _reason_, nor any _evidence_, exists for such a thing, but that does not appear to bother Gentry that there could have been ample amounts of polonium around which became fixed in the rocks that were so created. Even you would have to agree that this assumptive kind of blue-skying is scientifically _very_ NON-parsimonious. You begin with an utterly nonfalsifiable assumption, and draw partial conclusions therefrom. We are not going to get anywhere, scientifically or mineralogically speaking, doing that sort of impossible-to-investigate reasoning. IF you want to do a "God did it" thingie, please by all means indulge yourself. None of us can _prove_ your metaphysical assumptiveness is illegitimate. We can, however, clearly point out that it is quite _scientifically_ illegitimate. And _I_ am interested in what makes, made, can make, or _did_ make, those anomalous point-source pleochroic halos in biotite mica, not in utterly scientifically unproductive speculations derived from attempts to remain adherent to one religion's ancient tribal (Hebrew) writings.... There is the so called Gap Theory, in which the creation of the heavens and the earth in Gen 1:1 could have been millennia before the actual first day. This would have provided ample opportunity for U-238 decay into Po-218/214/210. It would. Unfortunuately, it is utterly, completely, hopelessly NON-scientific, and we cannot get any scientific _answer_ to what can have made these halos, from that kind of religious distortionism. However, even if absolutely no time elapsed between this creation event and the first day, that would mean that 3 days elapsed in which U-238 would have had a chance to start decaying. Even in a moderately sized U-238 lode, there will be significant amounts of decay in 3 days. In a _lode_, sure! In a three-micron _particle_? No way. Mr. Blosser, please review the decay chain for 238U. IN order to get even to _radon_, we need roughly: 4.5x10^9 years to get to 234Thorium and back to 234U, _after_which_ we need another 2.47x10^5 years to get to Thorium again (230Th this time), then 8x10^4 years to get to 226Ra, and then another 1600 years to get to 222Radon. ....And that's just for _one_atom_ to go through all its necessary decays to get merely to the Radon stage. "Even if" we make that "3 days" into a rather permissively long time, there's just no way the _average_ decays will generate enough alpha particles to make even _one_ visible halo from a three-micron particle with about 10^15 atoms in it.... At any rate, I hope this demonstrates that the correlation of Po halos to nearby U sources can be seen as quite acceptable in a creation model and is not a valid argument against it. Mr. Blosser, it has been my experience over a number of years, daily writing to creationists on various subjects, that _nothing_ that has ever been said has been a "valid argument against" the 'creation model' --_to_the_creationists_. It's a rare creationist indeed, who eventually collapses under the weight of the number of distortions and lacks of parsimony that are necessary to keep his antiscientific belief- system alive in the face of the hard sciences. I've seen a few, and have contributed to the extraction of at least two, but that number is woefully inadequate--disappointing, really--considering the apparent power of the findings gained through use of the Scientific Method. The only theologically important thing that my finding does, is establish that in at least every case that I have seen (and I _predict_, in any case that anyone's _going_to_ see), 'precursor' radioactives of some kind are _vitally_necessary_ to the formation of 'polonium'-type pleochroic halos, hence God either could not, or _did_ not, make any "polonium" halos as flat-out unambiguous evidence of His sudden-FIAT creation, by placing them in places where it would be _impossible_ for them to have formed any other way. IOW, God did _not_ give the creationists the "one irrefutable proof" of Genesis-type sudden FIAT creation that they would so dearly love to find. If He had made even _one_ findable halo with _NO_ other possible explanation for its existence, that'd be different, but instead, He fixed it (I see and predict) so that no point-source pleochroic halo so far known can be _unambiguously_ said to have been formed by the Genetic method--that all of them _can_have_ (hence "ambiguous") formed by natural processes. _MY_ work is partial and limited, but is enough for me to make this particular anti-creationist, anti-Gentry prediction, that NO halos will ever be found far, far, far away from some plausible source of radioactive elements. Furthermore, the burden of proof still remains on geology to provide a natural explanation for how the Po halos got there. You seem to be mistaken in thinking that a correlation such as we have in this case is all that is necessary, but that may only get you halfway to an answer. You have known about my hypothesis for some time now, and have ignored some of it while agreeing with other parts of it. I _certainly_ don't rest my argument on the above-discussed correlation. In fact, it was actually an afterthought, something that occurred to me long after I'd gotten back home and turned my kitchen table into a small, B&L professional microscope-equipped mineralogy lab. Unless you can come up with something better than radon diffusion, I am still waiting for someone to _refute_ my version of radon diffusion, sir, so I think your above might be labelled either "somewhat," or perhaps even "grossly," _premature_.... or hydrothermal sources (even worse), then the correlation can only ...And I've noted here and in my paper, that "hydrothermal" activity is utterly _unnecessary_ to my particular radon-migration hypothesis. be deemed coincidental since no formal causation is evident. hence the value of my prediction, eh? I predict that NO ONE will ever find "polonium" halos --or _any_other_ point-source pleochroic halos--in places where there is no possibility of other radioactive elements having been, or currently being, present. Now, if this correlation holds true, student by student, investigation after investigation, and year after year, it's going to eventually get extremely difficult to go on maintaining that this is a _"coincidence"_ instead of a _rule_.... One should also bear in mind that causal relationships must be thoroughly examined. While we could speculate that because they are I am the first to agree: MY sampling was/is cursory. A dozen mines in two states just does not provide enough of a sampling to draw definitive conclusions. However, I note that since the relationship _does_hold_ in my limited sampling, I can "go out on a limb" and make the prediction that I do make. An _independent_ field study or fifty (*g*), would be a very nice thing for me to watch unfolding.... always found together, that U-238 nearby is the cause of the polonium. Sounds good. We do know that U-238 will eventually decay It is simpler than that. There could be other things responsible for those halos, but there could NOT be any other thing that was not radioactive, and was not _local_to_the_mineral_ (say, within tens of feet or yards at least) that the halos are found in, that was responsible for them. IOW, I do NOT have to use this correlation between radioactives and halos (inv.: no radioactives and no halos), in order to argue 'polonium' halo formation issues. I need only establish the relationship itself, to suggest with extreme likelihood, that the radioactives are the ultimate source(s) of _any_and_all_ types of point- source pleochroic halo phenomena. (This correlation is general, non- specific.) However, there are isotopes in nature that are not only the product of a decay, but are also naturally occurring. Ar-40 for instance. Isn't it just possible that Po-218, for instance, is not only the daughter product of U-238, but is also naturally occurring? And Define "naturally occurring." NOT derived from a parent atom? Originally appearing in either the condensing planetary dust-disk, or in the first few days of God's FIAT-POOF! creation? No, Mr. Blosser, one should stick to the scientific data supporting one's arguments, and 218Po does not have a long enough half-life for ANY "original" or "primordial" 218Po to still be hanging around here, even if it was "made out of nowhere" only 7,000 years ago. that for whatever reason, coincidence maybe, natural Po-218 appeared nearby to U-238. Heck of an unreasonable (and horribly nonparsimonious) amount of "coincidence," I'd say.... Surely, a coincidence of that magnitude is no more impossible than, say, abiogenesis, or the odds of beneficial mutation. Afer all, (Bad choice of example, beneficial mutation, since we SEE that one happening in the labs and especially in the modern hospitals, where the descendants of earlier Staphylococcus aureii are laughing at the whole range of inventive, new, non-naturally-derived antibiotics that once could kill them easily....) evolution is a case study in how to defy impossible odds. Evolution is a study of what changes life goes through, and by backward- into-time extrapolation, what changes life went through, to produce what life we see around us now. It has nothing whatsoever to do with abiogenesis (the creation of life itself). Evolution is about life's _changes_, not about its _origination_. But that aside, the "probability" argument of the creationists suffers from one supercritical, glaring flaw: there is nothing at all in probability theory that says that a nearly-impossible event MUST ONLY occur at the END of an experimental run of which the low-probability event is a part. That is, if you shuffle a deck of cards, the probability that the Ace of Spades winds up on top is 1:52. If you shuffle them again, the probability remains the same. probabilistically speaking, then, you would have to shuffle the deck fifty-two times before the Ace of Spades has a 1:1 chance of being on top somewhere within that whole 52-shuffles run. BUT: probability theory does NOT say that the Ace of Spades can ONLY be on top _after_ fifty-two shufflings. It could just as easily have been on top after the _first_ shuffle. What the creationists want you to believe is that the likelihood of life forming "by itself" is SO tiny that only AFTER several billion-trillion TRIES could it have finally happened.... ....But probability doesn't work like that. The near-impossible event _could_have_ happened right away up front, on the first or second or third TRY, with not the slightest objecting peep emitted by probability theory, to indicate otherwise. The creationists' "probability" argument is good for convincing "the choir," certain science-ignorant idiots, religious wanna-believes, and mathematically challenged people; it has no effect on those of us who know enough about probability theory to be aware of this above critical flaw in their argument. So long as the creationists do not say the odds of life-from-non-life are, probabilistically speaking, _precisely_ZERO_, their argument lacks the teeth they think it has (and can convince, by Sophistry, their audiences that it has). (Please, by the way, do not let this side-trip into probability --to which you may wish to respond-- take us off of Polonium halos. I'm in here again _solely_ for that purpose, not to engage in arguing the entire range of creationist claims. I've 'been there' and _done-that_ for years, and I'm tired of it, and the T-shirt I got already has holes from overwear and overwashing (*grin*). These point-source pleochroic halos in biotite mica, however, continue to fascinate me. Entirely apart from the Cre/Evo aspects, the little beauties themselves are quite enjoyable to study; one never knows when --around the next corner, along the next crack, circumscribed about the next bignasty black damaged area-- one is going to see something that no one else has ever seen. That's rare, these days. It's rare also that one such as I --amateur scientist with Zip for 'academic credentials'-- can actually find something "new" or unexplained in a field as old and filled-in as mineralogy. Please don't try to take me elsewhere; I've been there already.)
