Carbon dating validity university of oklahoma dating
Assertion 4, you can see, is another special case of Assertion 1, and similarly false.
Radiocarbon dating is a method to determine the age of objects from antiquity.
(Ham et al., page 68.) C ratio in the past, or that this is "the technique's Achilles' heel" is incorrect.
The whole validity of radiocarbon dating for the past 10,000 years---the time span of interest to biblical chronology---hangs only on the tree-ring chronologies which are used to calibrate it. .) This process does not involve any assumption about historic radiocarbon to stable carbon ratios because the radiocarbon concentration in the tree-ring samples would be affected in exactly the same way as the radiocarbon concentration in the specimen to be dated. 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.
However, this problem is taken care of, by calibration curves, which account for the change in the ratio.
Calibrated radiocarbon dates are immune to any supposed change in decay rate of radiocarbon. This idea is promoted in The Answers Book and other sources.
There is another possibility, which may affect the accuracy of this dating method.
It is necessary that the dating sample be as uncontaminated as possible, to give it an accurate age.
However, in reality the ratio varies with time and place.
Hence, the ages are specified as 3400 BP (3400 years BP). The flaw in this method is that it assumes that the carbon-14/carbon-12 ratio has been the same till 1950, which is not the case in reality.
This idea is advanced, for example, in The Young Earth: C ratio was like before the industrial revolution, and all radiocarbon dating is made with this in mind.
