Validity and accuracy of carbon dating
Some of these other las include: Caron quote again from The Views Book: We can see that many seres of minerals are free from the same stream by the required processes of full, and these different people may have very up compositions. Assertion 3 is a through case of Assertion 1, and, today it, is false. That idea is no in The Images Book and other people.
Henry Morris as follows: These long time periods are computed by measuring the ratio of daughter to parent substance in a rock, and inferring an age based on this ratio. This age is computed under the assumption that the parent substance say, uranium gradually decays to the daughter substance say, leadso the higher the ratio of lead to uranium, the older the rock must be. While there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, e.
Geologists assert that generally speaking, older dates are found deeper down in the geologic column, which they nad as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older. But even if it is true that Validity and accuracy of carbon dating radiometric dates are found lower down in the geologic column which is open to questionthis can potentially be explained by processes occurring in magma sating which cause the lava erupting earlier to appear older than the lava erupting later. Lava erupting earlier would come from the top of the aaccuracy chamber, and lava erupting later would come from datlng down.
A number of processes could cause the parent substance to be depleted at the top of the magma chamber, or the daughter product to be enriched, both of which would cause the lava erupting earlier to appear very old according to radiometric dating, and lava erupting later to appear younger. Other possible confounding variables are the mechanisms that can alter daughter-to-parent ratios. We can see that many varieties of minerals are produced from the same magma by the different processes of crystallization, and these different minerals may have very different compositions.
It is possible that the ratio of daughter to parent substances for radiometric dating could differ in the different minerals. Clearly, it is important to have a good understanding of these processes in order to evaluate the reliability of radiometric dating. Other confounding factors such as contamination and fractionation issues are frankly acknowledged by the geologic community, but are not taken into consideration when the accuracy and validity of these dating methods are examined. The following quotation from Elaine G. Kennedy addresses this problem. Contamination and fractionation issues are frankly acknowledged by the geologic community. For example, if a magma chamber does not have homogeneously mixed isotopes, lighter daughter products could accumulate in the upper portion of the chamber.
If this occurs, initial volcanic eruptions would have a preponderance of daughter products relative to the parent isotopes. Such a distribution would give the appearance of age. As the magma chamber is depleted in daughter products, subsequent lava flows and ash beds would have younger dates. It does suggest at least one aspect of the problem that could be researched more thoroughly. The problems inherent in radiometric dating often cause them to be so unreliable that they contradict one another rather than validating each other.
It would really be nice if geologists would just do a double blind study sometime to find out what the distributions of the ages are.
In practice, geologists carefully select what rocks they will date, and have many explanations for discordant dates, so it's not clear how such a study could be done, but it might be Validity and accuracy of carbon dating good project for creationists. There is also evidence that many anomalies are never reported. There are so many complicated phenomena to consider like this that it calls the whole radiometric dating scheme into question. Only then can you gauge the accuracy and validity of that race. We need to observe when the race begins, how the race is run are there variations from the course, is the runner staying within the course, are they taking performance enhancing drugs, etc.
All bases must be covered if we are going to accurately time the race. This is the major flaw in radiometric dating, e. Secondly, you must have an observable time span so we can be certain nothing has affected the amount of the radioactive element being measured, e. Finally, we need to be certain about the end or finish point. This is some finite point in the future. Without an accurate starting time, an observable span in between, and an observable finish, our measurement cannot be deemed accurate. For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.
For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles, Rom 1: Beware of people who subscribe to a theory based upon naturalism and materialism exclusively. If you blindly accept the Theory of Evolution, you are in danger of believing a fairytale for grownups called the Theory of Evolution. Radiocarbon dates are based on the assumption that radioactive decay rates have been constant in the past.
To quote again from The Answers Book: Some recent, though controversial, research has raised the interesting suggestion that c the speed of light has decreased in historical times. If it is correct, then radioactive decay rates would automatically be affected, and would show artifically high ages. As with Assertion 1, Assertion 2 fails to account for the tree-ring calibration which is a routine part of modern radiocarbon dating. Although no convincing argument for a change in the speed of light over time has been made, the question is irrelevant to the validity of tree-ring calibrated radiocarbon dates. As with variation in atmospheric radiocarbon concentration, the decay rate of radiocarbon in tree-ring calibration samples would be affected in exactly the same way as the decay rate of radiocarbon in the specimen to be dated.
Calibrated radiocarbon dates are immune to any supposed change in decay rate of radiocarbon. Assertion 2 is false. A pre-Flood vapor canopy would cause pre-Flood specimens to appear to be very old. This idea is promoted in The Answers Book and other sources. It is based on the idea that a pre-Flood vapor canopy protected the earth's atmosphere from cosmic radiation and thereby caused a decrease in radiocarbon production. Something like a vapor canopy could affect the atmospheric radiocarbon concentration, but this fact is, once again, irrelevant to the validity of modern tree-ring calibrated radiocarbon dates. Assertion 3 is a special case of Assertion 1, and, like it, is false.
The earth's magnetic field was stronger in the past, causing inflated ages. This idea is similar to Assertion 3, but suggests instead that the cosmic radiation was shielded in the past by a stronger magnetic field of the earth.
