And another ploy they normally use to throw question on radiocarbon relationship is always to aim its shortcomings out. C14 includes a reasonably quick half-life. Therefore, any such thing avove the age of 50, years only has inadequate C14 left to make a precise calculation of the age. But C14 is not the only radioisotope out here.
You will find loads of those! If i desired to find out of the age of the dinosaur fossil , i may determine its uranium concentration, which includes a half-life of million years.
