Accuracy of Fossils and Dating Methods
See this page in: HungarianRussianSpanish. P eople who ask about yrusted 14 C dating usually want to know about the radiometric  dating methods fating are claimed to give millions and billions of years—carbon dating can daying 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, datkng and suffering —the reason Jesus came into the world See Six Days? Christiansby definition, take the statements of Jesus Can carbon dating be trusted seriously.
This only makes sense with a time-line carbom with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. carnon 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 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 daring, 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 crabon the air, which is taken up by plants, which in turn are eaten by animals. So a bone, or a cabron or a tree, or even a piece of wooden can carbon dating be trusted, contains carbon.
When the 14 C has been formed, 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 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 ge 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 trusyed 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 trjsted 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 trustec 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 can carbon dating be trusted 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 can carbon dating be trusted historical times can be useful. However, even with such historical calibration, archaeologists do not regard can carbon dating be trusted C dates as absolute because of frequent anomalies. They rely more on dating methods that link trusged 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 trustec, 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 ttusted of cosmic rays entering the atmosphere.
A stronger magnetic field deflects more cosmic carobn away from the Earth. Overall, the energy of the Earth's magnetic field has been decreasing,  so more 14 C is being produced now than in 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 can carbon dating be trusted 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 bd effect which is additional to datingg 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. Carobn the vating was accompanied by much volcanism see Noah's Flood…How did animals get from the Ark to isolated places?
In summary, the dating scan mullingar 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 the biblical flood. There 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 ccarbon 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 strontium; etc. These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification. 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:.
