When a “date” differs from that expected, researchers readily invent excuses for rejecting the result.The common application of such posterior reasoning shows that radiometric dating has serious problems.This also has to be corrected for.[2] Second, the ratio of C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible.Accordingly, carbon dating carefully applied to items from historical times can be useful.These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.

A stronger magnetic field deflects more cosmic rays away from the Earth.That is, they take up less than would be expected and so they test older than they really are.Furthermore, different types of plants discriminate differently.We will deal with carbon dating first and then with the other dating methods.Carbon has unique properties that are essential for life on Earth.
