Young earth radiometric dating
Author: By Curt Sewell“How can creationists expect people to accept a young earth when science has proved through radiometric dating that the earth is billions of years old?” This article addresses that question, which represents the thinking of a large number of people today.Certainly the majority of scientists accept radiometric dating.And yet, there is really no scientific reason proving that radiometric dating is correct, and a number of evidences showing that it doesn’t work. We’ll find that faith in materialism, and rejection of any supernatural activity, is the foundation stone of radiometric analysis, even before any measurements are made.Reasons given usually involved detrital intrusion, leakage or leaching of some of the isotopes in the sample, and sometimes the initial isotopic content of the sample.For K-Ar dates, it’s easy to blame argon loss if the reported age is too short, or argon absorption if it’s too long.Most people, even the experts in the field, forget the assumptions on which radiometric dating is based.
Experimental Errors The methods that give ancient ages produce almost as many “wrong” answers as “right” ones.
It is well known that argon, which is a gas, diffuses easily through rock, and there is no way of knowing whether that may have happened in any given case.
Errors are particularly bad with the K-Ar (potassium-argon) method. Joan Engels wrote: It is now well known that K-Ar ages obtained from different minerals in a single rock may be strikingly discordant.3 Skull 1470 In 1972 Richard Leakey found a skull, near Lake Rudolf in Kenya, that he said was “virtually indistinguishable” from that of a modern human.
All of these dating methods begin with some radioactive isotope such as U-238, U-235, Th-232, K-40, or Rb-87. These elements are naturally radioactive, that is, they spontaneously emit an alpha or a beta particle and, as a result, are transformed into some different element, called the “daughter” isotopes.
For those who would like more details, these systems are briefly described in the boxes on the following pages.
