How the carbon clock works
P eople who ask about carbon 14 C 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.
People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days? Christiansby definition, take the statements of Jesus Christ seriously.
He said. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. Carbon has unique properties that are essential for life on Earth. One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon, or 14 C, or radiocarbon.
Carbon is made when cosmic rays knock neutrons out of atomic nuclei in the upper atmosphere. These displaced neutrons, now moving fast, hit ordinary nitrogen 14 N at lower altitudes, converting it into 14 C. Unlike common carbon 12 C14 C is unstable and slowly decays, changing it back to nitrogen and releasing energy. This instability makes it radioactive.
Ordinary carbon 12 C is found in the carbon dioxide CO 2 in the air, which is taken up by plants, which in turn are eaten by animals.
So a bone, or a leaf or a tree, or even a piece of wooden furniture, contains carbon. When the 14 C has been formed, christian view of radioactive decay dating, like ordinary carbon 12 Cit combines with oxygen to give carbon dioxide 14 CO 2and so it also gets cycled through the cells of plants and animals. Because 14 C is so well mixed up with 12 C, we expect to find that this ratio is the same if we sample a leaf from a tree, or a part of your body. In living things, although 14 C atoms are constantly changing back to 14 N, they are still exchanging carbon with their surroundings, so the mixture remains about the same as in the atmosphere.
However, as soon as a plant or animal dies, the 14 C atoms which decay are no longer replaced, so the amount of 14 C in that once-living thing decreases as time goes on. Obviously, this works only for things which were once living.
It cannot be used to date volcanic rocks, for example. The rate of decay of 14 C is such that half of an amount will convert back to 14 N in 5, years plus or minus 40 years.
Anything over about 50, years old, should theoretically have no detectable 14 C left. That is why radiocarbon dating cannot give millions of years. In fact, if a sample contains 14 C, it is good evidence that it is not millions of years old.
However, things are not quite so simple. First, plants discriminate against carbon dioxide containing 14 C. That is, they take up less than would be expected and so they test older than they really are. Furthermore, different types of plants discriminate differently. This also has to be corrected for. This would make things which died at that time appear older in terms of carbon dating. Then there was a rise in 14 CO 2 with the advent of atmospheric testing of atomic bombs in the s.
Measurement of 14 C in historically dated objects e. Accordingly, carbon dating carefully applied to items christian view of radioactive decay dating historical times can be useful. However, even with such historical calibration, archaeologists do not regard 14 C dates as absolute because of frequent anomalies.
They rely more on dating methods that link into historical records. Outside the range of recorded history, calibration of the 14 C "clock is not possible. The amount of cosmic rays penetrating the Earth's atmosphere affects the amount of 14 C produced and therefore dating the system. The amount of cosmic rays reaching the Earth varies with the sun's activity, and with the Earth's passage through magnetic clouds as the solar system travels around the Milky Way galaxy.
The strength of the Earth's magnetic field affects the amount of cosmic rays entering the atmosphere. A stronger magnetic field deflects more cosmic rays away from the Earth. Overall, the energy of the Earth's magnetic field has been decreasing, [5] so more 14 C is being produced now than christian view of radioactive decay dating the past. This will make old things look older than they really are. Also, the Genesis flood would have greatly upset the carbon balance. The flood buried a huge amount of carbon, which became coal, oil, etc.
Total 14 C is also proportionately lowered at this time, but whereas no terrestrial process generates any more 12 C, 14 C is continually being produced, and at a rate which does not depend on carbon levels it comes from nitrogen. Unless 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.
Creationist researchers have suggested that dates of 35, - 45, years should be re-calibrated to the biblical date of the flood. Also, volcanoes emit much CO 2 depleted in 14 C.
Since the flood was accompanied by much volcanism see Noah's Flood…How did animals get from the Ark to isolated places? In summary, the carbon method, when corrected for the effects of the flood, can give useful results, but needs to be applied carefully.
It does not give dates of millions of years and when corrected properly fits well with christian view of radioactive decay dating biblical flood. Christian view of radioactive decay dating are various other radiometric dating methods used today to give ages of millions or billions of years for rocks. These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.
For example, potassium decays to argon; uranium decays to lead via other elements like radium; uranium decays to lead; rubidium decays to christian view of radioactive decay dating etc.
These techniques are applied to igneous rocks, christian view of radioactive decay dating, and are normally seen as giving the time since solidification, christian view of radioactive decay dating.
The isotope concentrations can be measured very accurately, but isotope concentrations are not dates. To derive ages from such measurements, unprovable assumptions have to be made such as:. The starting christian view of radioactive decay dating are known for example, christian view of radioactive decay dating, that there was no daughter isotope present at the start, or that we know how much was there.
There is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years. However, there are still patterns to be explained. Geologist John Woodmorappe, in his devastating critique of radioactive dating, [8] points out that there are other large-scale trends in the rocks that have nothing to do with radioactive decay. The common application of such posterior reasoning shows that radiometric dating has serious problems.
For example, researchers applied posterior reasoning to the dating of Australopithecus ramidus fossils. So they looked at some basalt further removed from the fossils and selected 17 of 26 samples to get an acceptable maximum age of 4. The other nine samples again gave much older dates but the authors decided they must be contaminated and discarded them.
That is how radiometric dating works. It is very much driven by the existing long-age world view that pervades academia today. A similar story surrounds the dating of the primate skull known as KNM-ER Various other attempts were made to date the volcanic rocks in the area. Over the years an age of 2. After this was widely accepted, further studies of the rocks brought the radiometric age down to about 1. Such is the dating game. Are we suggesting that evolutionists are conspiring to massage the data to get what they want?
No, not generally. It is simply that all observations must fit the prevailing paradigm. We must remember that the past is not open to the normal processes of experimental science, that is, repeatable experiments in the present. A scientist cannot do experiments on events that happened in the past.
Scientists do not measure the age of rocks, they measure isotope concentrations, and these can be measured extremely accurately. Those involved with unrecorded history gather information in the present and construct stories about the past. The level of proof demanded for such stories seems to be much less than for studies in the empirical sciences, such as physics, chemistry, molecular biology, physiology, etc. Williams, an expert in the environmental fate of radioactive christian view of radioactive decay dating, identified 17 flaws in the isotope dating reported in just three widely respected seminal papers that supposedly established the christian view of radioactive decay dating of the Earth at 4.
The forms issued by radioisotope laboratories for submission with samples to be dated commonly ask how old the sample is expected to be. If the techniques were absolutely objective and reliable, such information would not be necessary.
If the long-age dating techniques were really objective means of finding the ages of rocks, christian view of radioactive decay dating, they should work in situations where we know the age. Furthermore, different techniques should consistently agree with one another. The secular scientific literature lists many examples of excess argon causing dates of millions of years in rocks of known historical age. This is consistent with a young world—the argon has had too little time to escape.
So data are again selected according to what the researcher already believes about the age of the rock, christian view of radioactive decay dating. Geologist Dr. Steve Austin sampled basalt from the base of the Grand Canyon strata and from the lava that spilled over the edge of the canyon.
By evolutionary reckoning, the latter should be a billion years christian view of radioactive decay dating than the basalt from the bottom. Standard laboratories analyzed the isotopes.
The rubidium-strontium isochron technique suggested that the recent lava flow was Ma older than the basalts beneath the Grand Canyon—an impossibility. If the dating methods are an objective and reliable means of determining ages, christian view of radioactive decay dating, they should agree.
If a chemist were measuring the sugar content of blood, all valid methods for the determination would give the same answer within the limits of experimental error. However, with radiometric dating, the different techniques often give quite different results.
In the study of the Grand Canyon rocks by Austin, different techniques gave different results. Techniques that give results that can be dismissed just because they don't agree with what we already believe cannot be considered objective.

Evidence for a rapid formation of geological strata, as in the biblical flood. Some of the evidences are: lack of erosion between rock layers supposedly separated in age by many millions of years; lack of disturbance of rock strata by biological activity worms, roots, etc. For more, see books by geologists Morris [26] and Austin.
Red blood cells and hemoglobin have been found in some unfossilized! dinosaur bone. But these could not last more than a few thousand years—certainly not the 65 Ma since the last dinosaurs lived, according to evolutionists. The Earth's magnetic field has been decaying so fast that it looks like it is less than 10, years old.
Rapid reversals during the flood year and fluctuations shortly after would have caused the field energy to drop even faster. Radioactive decay releases helium into the atmosphere, but not much is escaping. This helium originally escaped from rocks. This happens quite fast, yet so much helium is still in some rocks that it has not had time to escape—certainly not billions of years.
A supernova is an explosion of a massive star—the explosion is so bright that it briefly outshines the rest of the galaxy. The supernova remnants SNRs should keep expanding for hundreds of thousands of years, according to physical equations. Yet there are no very old, widely expanded Stage 3 SNRs, and few moderately old Stage 1 ones in our galaxy, the Milky Way, or in its satellite galaxies, the Magellanic Clouds. The moon is slowly receding for the Earth at about 4 centimeters 1.
But even if the moon had started receding from being in contact with the Earth, it would have taken only 1. This gives a maximum age of the moon, not the actual age. This is far too young for evolutionists who claim the moon is 4. Salt is entering the sea much faster than it is escaping. The sea is not nearly salty enough for this to have been happening for billions of years.
Even granting generous assumptions to evolutionists, the sea could not be more than 62 Ma years old—far younger than the billions of years believed by the evolutionists. Again, this indicates a maximum age, not the actual age. Russell Humphreys gives other processes inconsistent with billions of years in the pamphlet Evidence for a Young World. Creationists cannot prove the age of the Earth using a particular scientific method, any more than evolutionists can.
They realize that all science is tentative because we do not have all the data, especially when dealing with the past. The atheistic evolutionist W. Provine admitted:. In reality, all dating methods, including those that point to a young Earth, rely on unprovable assumptions. Creationists ultimately date the Earth historically using the chronology of the Bible.
This is because they believe that this is an accurate eyewitness account of world history, which bears the evidence within it that it is the Word of God , and therefore totally reliable and error-free. What the do the radiometric dates of millions of years mean, if they are not true ages? 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.
The isochron dating technique was thought to be infallible because it supposedly covered the assumptions about starting conditions and closed systems. Zheng wrote:. This problem cannot be overlooked, especially in evaluating the numerical time scale. Similar questions can also arise in applying Sm-Nd [samarium-neodymium] and U-Pb [uranium-lead] isochron methods. Clearly, there are factors other than age responsible for the straight lines obtained from graphing isotope ratios.
Another currently popular dating method is the uranium-lead concordia technique. This effectively combines the two uranium-lead decay series into one diagram. Numerous models, or stories, have been developed to explain such data.
Again, the stories are evaluated according to their own success in agreeing with the existing long ages belief system. Andrew Snelling has suggested that fractionation sorting of elements in the molten state in the Earth's mantle could be a significant factor in explaining the ratios of isotope concentrations which are interpreted as ages.
As long ago as , Nobel Prize nominee Melvin Cook , professor of metallurgy at the University of Utah, pointed out evidence that lead isotope ratios, for example, may involve alteration by important factors other than radioactive decay.
Thorium has a long half-life decays very slowly and is not easily moved out of the rock, so if the lead came from thorium decay, some thorium should still be there. The concentrations of lead, lead, and lead suggest that the lead came about by neutron capture conversion of lead to lead to lead When the isotope concentrations are adjusted for such conversions, the ages calculated are reduced from some Ma to recent.
Other ore bodies seemed to show similar evidence. Cook recognized that the current understanding of nuclear physics did not seem to allow for such a conversion under normal conditions, but he presents evidence that such did happen, and even suggests how it could happen. Physicist Dr. Robert Gentry has pointed out that the amount of helium and lead in zircons from deep bores is not consistent with an evolutionary age of 1, Ma for the granite rocks in which they are found.
Furthermore, the amount of helium in zircons from hot rock is also much more consistent with a young Earth helium derives from the decay of radioactive elements. The lead and helium results suggest that rates of radioactive decay may have been much higher in the recent past.
Humphreys has suggested that this may have occurred during creation week and the flood. This would make things look much older than they really are when current rates of decay are applied to dating. Whatever caused such elevated rates of decay may also have been responsible for the lead isotope conversions claimed by Cook above. Decaying radioactive particles in solid rock cause spherical zones of damage to the surrounding crystal structure.
A speck of radioactive element such as Uranium, for example, will leave a sphere of discoloration of characteristically different radius for each element it produces in its decay chain to lead Gentry has researched radiohalos for many years, and published his results in leading scientific journals.
Some of the intermediate decay products—such as the polonium isotopes—have very short half-lives they decay quickly. For example, Po has a half-life of just 3 minutes.
Curiously, rings formed by polonium decay are often found embedded in crystals without the parent uranium halos. Now the polonium has to get into the rock before the rock solidifies, but it cannot derive a from a uranium speck in the solid rock, otherwise there would be a uranium halo.
Either the polonium was created primordial, not derived from uranium , or there have been radical changes in decay rates in the past. Gentry has addressed all attempts to criticize his work. Whatever process was responsible for the halos could be a key also to understanding radiometric dating. There are many lines of evidence that the radiometric dates are not the objective evidence for an old Earth that many claim, and that the world is really only thousands of years old.
We don't have all the answers, but we do have the sure testimony of the Word of God to the true history of the world. Today, a stable carbon isotope, 13 C , is measured as an indication of the level of discrimination against 14 C. Radiation from atomic testing, like cosmic rays, causes the conversion of 14 N to 14 C. Tree ring dating dendrochronology has been used in an attempt to extend the calibration of the calibration of carbon dating earlier than historical records allow, but this depends on temporal placement of fragments of wood from long dead trees using carbon dating, assuming straight-line extrapolation backwards.
McDonald and R. Government Printing Office, Washington D. Musk ox muscle was dated at 24, years, but hair was dated at 17, years.
Corrected dates bring the difference in age approximately within the life span of an ox. With sloth cave dung, standard carbon dates of the lower layers suggested less than 2 pellets per year were produced by the sloths. Correcting the dates increased the number to a more realistic 1.

Dating bryant air conditioner? Whitney's article, 'The Age of the Earth: Comments on Some Geologic Methods Used in its Interpretation," appeared in the Bulletin of Deluge Geology in December , and was the first modern defense of a recent creation that I found. In this paper, Whitney developed the evidences for a young earth based on: 1 influx of sodium and other chemicals into the ocean; 2 depletion of the land by leaching; 3 sedimentation rates; 4 build-up of helium in the atmosphere; 5 disintegration of comets; 6 influx of meteorites and their nickel-iron contents on the earth; and 7 efflux of water from earth's interior by volcanism.
Most of these evidences are still relevant. Whitney then added a brief critique of the assumptions in radioactive dating. He commented on the many discordances in results, the problem of separating "common lead" from radiogenic lead, the possibility that some of the supposed radiogenic elements could have been added either before or after deposition, the possibility of changes in disintegration rates, the possibility of selective leaching, and the many conflicts with previously assumed geologic ages.
These criticisms also are still valid. Whitney published many other papers, as well as two small books, all advocating recent creation and flood geology. He was even able to get at least one paper included in the Reports of the Committee on Geologic Time he was on good terms with Professor Lane and in the Pan-American Geologist.
There were a few others in the old Creation-Deluge Society which I joined in who believed in recent creation, but the next important article—so far as I know—was one by geologist Clifford Burdick, entitled "The Radioactive Time Theory and Recent Trends in Methods of Reckoning Geologic Time.
It covered much the same ground as Whitney had done, but in more detail and with better documentation. It was instrumental in my own decision to abandon the gap theory I had already given up on theistic evolution and the day-age theory in favor of the young earth. My first book, That You Might Believe published in , had briefly questioned the reliability of radioactive dating, but also had allowed for the gap theory.
But then I read Burdick's paper and was convinced that such a compromise was unnecessary scientifically. In the meantime, I had made a verse-by-verse study of the whole Bible on this subject and found that the Bible could not legitimately allow for an old earth see my book, Biblical Creationism , which demonstrates this fact by analyzing every relevant Biblical passage.
In I enrolled for graduate work at the University of Minnesota, taking a minor in geology and spending much time in the geological library there and studying carefully the Annual Reports of the Committee on Geologic Time.
During this period, I also revised my book, deleting the discussion of the gap theory and expanding its critique of radiometric dating. The new edition was published in by Moody under the title The Bible and Modem Science. At the university I also took a course on geophysics which included sections on radiometric dating. In , I presented a paper at the annual convention of the American Scientific Affiliation where I first met John Whitcomb , entitled "Biblical Evidence for a Recent Creation and Worldwide Flood.
could be swayed by Biblical evidences. They and others like them will accept literal creationism only when they are convinced that secular scientists believe it. However, this conference and my later correspondence with John Whitcomb did lead finally to the book, The Genesis Flood , and this in turn to the Creation Research Society and the modern revival of literal Biblical creationism. My portion of The Genesis Flood included a page discussion of radiometric dating and its fallacies as I saw them, at least with suggested resolutions.
The Creation Research Society was formed in and its quarterly publications have included a few papers critiquing radiometric dating, but these have been relatively few, considering the critical importance of the subject. The most extensive was a paper by John Woodmorappe, "Radiometric Chronology Reappraised," published in the CRS Quarterly in September and recently reissued by ICR in an anthology of Woodmorappe articles entitled Studies in Flood Geology.
There have been others who have written on the subject, of course, but the question is still not settled.
