Isochron radiometric dating new thread
He also states that this applies to other methods of radiometric dating, so even independent verification by other radiometric dating methods does not validate the accuracy of any of them. The other seems to have the same misunderstanding of radiometric dating that Howard does.At any rate, looking at Howard's scientific record, nothing leads me to believe that he has any real expertise in radiometric dating, and it shows.Recently, I came across an article by William Howard of University of Alaska-Fairbanks in the Journal of Chemical Education. Howard's basic point is summed up in his last paragraph - "knowing all of the products from the potassium-argon reaction is necessary in order to know the age of the mineral [being dated]." Howard says that nobody has ever studied the 40K- 40Ar reaction in minerals enough to know all of the products.For this reason, he says it's impossible for us to be sure that radiometric dating is accurate.However, it is possible that I may have been somewhat hasty in my characterization of Howard.In the HTML paper you cite, Howard states: Ar method in 1997, and the age was determined to be 1925 years old, differing by only seven years from the historically accepted age of 1918 years old.
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.And, in addition, loss of or contamination by parent or daughter isotopes would corrupt the data to the point where the method would clearly indicate some sort of problem has occurred.Again, to get a seemingly valid by false date by this method would require an extraordinary conspiracy on the part of nature; the "leakage" would have to occur in just the right way in each and every crystal in the sample, regardless of the specific minerals, to yield a result that looks valid.
