No. 25: Jan-Feb 1983
Responding to letters published in the June 1982 issue of Physics Today that insisted (some, very emotionally) that no evidence exists for a very young earth, Robert V. Gentry summarized three kinds of evidence that certainly seem to undermine current dating schemes.
"...how did the surrounding rocks crystalize rapidly enough so that there were crystals available ready to be imprinted with radiohalos by alpha-particles from Po218 ? This would imply almost instantaneous cooling and crystallization of these granitic minerals -- and we know of no mechanism that will remove heat so rapidly; the rocks are supposed to have cooled over millennia, if not tens of millennia."
"Thus ages of the entire stratigraphic column may contain epochs less than 0.001% the duration of those now accepted and found in the literature."
(Gentry, Robert V.; "Creationism Discussion Continued," Physics Today, 35: 13, October 1982.)
Comment. Scientists admit that Gentry's work raises questions but apparently would rather live with the anomalies than with the thought of a young earth!
