decay rates are constants -- but this is a commone creationist position: suppose, ad hoc, the rates changed, just like the speed of light ad-hoc-ly did.
No one is arguing that decay rates are constant (at least I hope no one is arguing that). The valid question has always been "have decay rates really been constant for millions of year?"
First of all, to say yes is ONLY an assumption, it is not scientific. It can in no way be proven.
Secondly, it is completely in line with the scientific spirit to question and test to find out if there is any evidence to suggest that they havent been constant.
Third, to supress, reject, and criticize such research is against true scientific spirit.
