Radiometric dating uncertainty

Like evolution, theories about Earth’s age derived from radiometric dating methods are virtually uncontested in the scientific community.But they are also a prime target of “young Earth” creationists, who believe the planet and its life were created fairly recently by God.Her letters say the paper “is written to create confusion in [the] primary audience—undergraduate chemistry students—by implying there is a controversy about the validity of radiometric dating.” The paper’s author, William A.Howard, an assistant chemistry professor at the University of Alaska, Fairbanks, says he chose the topic for students because it would motivate them to think passionately and critically.

Additionally, Ar, K/Ar, Rb/Sr, U/Pb, and Sm/Nd decay chains to date mineral-containing martian meteorites known as nakhlites.All the measurements—despite the very different subsequent chemistries involved—yield the same age, 1.3 billion years.Howard’s uncommon viewpoints on the subject have created a stir in the chemistry and geology departments at the University of Alaska.“I saw no problem, and I think that was the view of the administration as a whole,” Clausen says.

“I wanted to pick a subject that people would get emotional about,” he admits.
