Atoms and molecules naturally move around, and they do so in such as way as to even out their concentrations.As someone who has studied radioactivity in detail, I have always been a bit amused by the assertion that radioactive dating is a precise way to determine the age of an object.This false notion is often promoted when radioactive dates are listed with utterly unrealistic error bars.In this report, for example, we are told that using one radioactive dating technique, a lunar rock sample is 4,283 million years old, plus or minus 23 million years old.
