One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.So, we have a “clock” which starts ticking the moment something dies.Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.Anything over about 50,000 years old, should theoretically have no detectable C.That is, they take up less than would be expected and so they test older than they really are.The rate of decay of N in 5,730 years (plus or minus 40 years).

Perhaps no concept in science is as misunderstood as "carbon dating." Almost everyone thinks carbon dating speaks of millions or billions of years.

In theory, it might be useful to archaeology, but not to geology or paleontology.

Furthermore, the assumptions on which it is based and the conditions which must be satisfied are questionable, and in practice, no one trusts it beyond about 3,000 or 4,000 years, and then only if it can be checked by some historical means.

That is until careful measurements revealed a significant disequalibrium. All the present C-14 would accumulate, at present rates of production and build up, in less than 30,000 years!

Thus the earth's atmosphere couldn't be any older than this.
