Doesn't Carbon-14 Dating Disprove the Bible? | Answers in Genesis

who ask about carbon-14 (14c) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. this would make things which died at that time appear older in terms of carbon dating. some may have mistaken this to mean that the sample had been dated to 20,000 radiocarbon years. gets its carbon straight from the air, complete with a full dose of c-14. for example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons. "back to genesis" way of thinking insists that the flood of noah's day would have removed a great deal of the world's carbon from the atmosphere and oceans, particularly as limestone (calcium carbonate) was precipitated. of the many fallacious assumptions used in the dating process, many people believe Carbon-14 dating disproves the biblical timeline. carbon (12c)is found in the carbon dioxide (co2) in the air, which is taken up by plants, which in turn are eaten by animals. however, with radiometric dating, the different techniques often give quite different results. normally occurs as carbon-12, but radioactive carbon-14 may sometimes be formed in the outer atmosphere as nitrogen-14 undergoes cosmic ray bombardment. they rely more on dating methods that link into historical records.. willard libby, the founder of the carbon-14 dating method, assumed. to do this, scientists use the main isotope of carbon, called carbon-12 (12c). samples of coal have been found with radiocarbon ages of only 20,000 radiocarbon years or less, thus proving the recent origin of fossil fuels, probably in the flood. continuous series of tree-ring dated wood samples have been obtained for roughly the past 10,000 years which give the approximate correct radiocarbon age, demonstrating the general validity of the conventional radiocarbon dating technique.

    field of radiocarbon dating has become a technical one far removed from the naive simplicity which characterized its initial introduction by libby in the late 1940's. rather, they lend support to the idea that significant perturbations to radiocarbon have occurred in the past. (c-14) dating is one of the most reliable of all the radiometric. when the 14c has been formed, like ordinary carbon (12c), it combines with oxygen to give carbon dioxide (14co2), and so it also gets cycled through the cells of plants and animals., a stable carbon isotope, 13c , is measured as an indication of the level of discrimination against 14c. of c-14’s short half-life, such a finding would argue that carbon. snelling, dating dilemma: fossil wood in ancient sandstone: creation ex nihilo 21(3):39–41, 1992. the common application of such posterior reasoning shows that radiometric dating has serious problems. radiocarbon dates and tree-ring dates of these other trees agree with those. also, it does not coincide with what creationist scientists would currently anticipate based upon our understanding of the impact of the flood on radiocarbon., any instrument which is built to measure radiocarbon has a limit beyond which it cannot separate the signal due to radiocarbon in the sample from the signal due to background processes within the measuring apparatus.-14 dating, using the question-answer format that has proved so useful to. the bristlecone pine calibration of c-14 dating was worked out by. for this reason special precautions need to be exercised when sampling materials which contain only small amounts of radiocarbon. on one particular form of radiometric dating—carbon dating—we will.

    carbon-14 is mostly used to date once-living things (organic material). to salvage carbon dating are many and varied, with calibration curves attempting to bring the c-14 "dates" in line with historical dates, but these produce predictably unreliable results. living things, although 14c atoms are constantly changing back to 14n, they are still exchanging carbon with their surroundings, so the mixture remains about the same as in the atmosphere. summary, the carbon-14 method, when corrected for the effects of the flood, can give useful results, but needs to be applied carefully. accordingly, carbon dating carefully applied to items from historical times can be useful. for example, a series of fossilized wood samples that conventionally have been dated according to their host strata to be from tertiary to permian (40-250 million years old) all yielded significant, detectable levels of carbon-14 that would conventionally equate to only 30,000-45,000 years “ages” for the original trees. are many examples where the dating methods give “dates” that are wrong for rocks of known age.. hunziker, editors, lectures in isotope geology, “u-th-pb dating of minerals,” by d. it cannot be used directly to date rocks; however, it can potentially be used to put time constraints on some inorganic material such as diamonds (diamonds could contain carbon-14). carbon dating says nothing at all about millions of years, and often lacks accuracy even with historical specimens, denying as it does the truth of the great flood. whatever process was responsible for the halos could be a key also to understanding radiometric dating. the shells of live freshwater clams have been radiocarbon dated in excess of 1600 years old, clearly showing that the radiocarbon dating technique is not valid. the wood was “dated” by radiocarbon (14c) analysis at about 45,000 years old, but the basalt was “dated” by potassium-argon method at 45 million years old! to answer this question, it is necessary to scrutinize further the experimental results from the various dating techniques, the interpretations made on the basis of the results and the assumptions underlying those interpretations. similar story surrounds the dating of the primate skull known as knm-er 1470.

    radiocarbon is not suitable for this purpose because it is only applicable: a) on a time scale of thousands of years and b) to remains of once-living organisms (with minor exceptions, from which rocks are excluded). 12c is a stable isotope of carbon, it will remain constant; however,The amount of 14c will decrease after a creature dies.[24] the accompanying checks showed that the 14c date was not due to contamination and that the “date” was valid, within the standard (long ages) understanding of this dating system. taylor, “carbon dioxide in the antediluvian atmosphere,” creation research society quarterly, 1994, 30(4):193-197. no concept in science is as misunderstood as "carbon dating." however, it is important to distinguish between "radiocarbon years" and calendar years. then cross-matching of ring patterns is used to calibrate the carbon “clock”—a somewhat circular process which does not give an independent calibration of the carbon dating system. on the inaccuracies found using the Carbon-14 dating method, and the various other radioactive dating methods.-14 (14c), also referred to as radiocarbon, is claimed to be a reliable. williams, “long-age isotope dating short on credibility,” cen technical journal, 1992, 6(1):2-5. invalidate radiocarbon dates of objects younger than twenty thousand years and is. any event, the calibration tables which have been produced from tree rings do not support the conventional steady-state model of radiocarbon which libby introduced. even a hypothetical sample containing absolutely no radiocarbon will register counts in a radiocarbon counter because of background signals within the counter. this effect (which is additional to the magnetic field issue just discussed) were corrected for, carbon dating of fossils formed in the flood would give ages much older than the true ages. just prior to the flood might have had 500 times more carbon in.

such a procedure introduces a bias into the construction of the tree-ring chronology for the earliest millennia which could possibly obscure any unexpected radiocarbon behavior. note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old. if this water is in contact with significant quantities of limestone, it will contain many carbon atoms from dissolved limestone. radiometric dating methods use scientific procedures in the present to interpret what has happened in the past. it is not correct to state or imply from this evidence that the radiocarbon dating technique is thus shown to be generally invalid. fossil wood in ancient lava flow yields radiocarbon, creation ex nihilo 20(1):24–27, 1997. dating of grand canyon rocks: another devastating failure for long-age geology. second characteristic of the measurement of radiocarbon is that it is easy to contaminate a sample which contains very little radiocarbon with enough radiocarbon from the research environment to give it an apparent radiocarbon age which is much less than its actual radiocarbon age. the flood buried a huge amount of carbon, which became coal, oil, etc., creationists who complain about double rings in their attempts to disprove. dating can easily establish that humans have been on the earth for. since limestone contains very little, if any, radiocarbon, clam shells will contain less radiocarbon than would have been the case if they had gotten their carbon atoms from the air. suess, on the relationship between radiocarbon dates and true sample. by radiocarbon dating a piece of wood which has been dated by counting the annual growth rings of trees back to when that piece of wood grew, a calibration table can be constructed to convert radiocarbon years to true calendar years.-argon and argon-argon dating of crustal rocks and the problem of excess argon.

at the present time it appears that the conventional radiocarbon dating technique is on relatively firm ground for dates which fall within the past 3,000 years. critical assumption used in carbon-14 dating has to do with this ratio. using the carbon-14 method would incorrectly assume that more 14c. are not so much interested in debunking radiocarbon as we are in developing a proper understanding of it to answer many of our own questions regarding the past. unlike common carbon (12c), 14c is unstable and slowly decays, changing it back to nitrogen and releasing energy. to suggest how much this would affect the radiocarbon dates. radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth. 30,000 years, and if the carbon reservoir has not changed appreciably. flood would have buried large amounts of carbon from living organisms. one example is k-ar “dating” of five historical andesite lava flows from mount nguaruhoe in new zealand. radiometric dating methods have proved the earth to be billions of years. this gives the clam shell an artificially old radiocarbon age.. from the university of toronto doing research in accelerator mass spectrometry, a technique now widely used in radiocarbon dating. so, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons. role might the genesis flood have played in the amount of carbon?
