Carbon dating limit
It makes no sense at all if man appeared at the end of billions of years.
We will deal with carbon dating first and then with the other dating methods.
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.
Furthermore, different types of plants discriminate differently.
This also has to be corrected for. Second, the ratio of C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible.
I read that the C14 method is only good for up to 60,000 years I began to wonder why exactly?
Is there something else derived that formula on the page to give you a 60,000 year maximum or is it just in the half life of the C14 itself?
This is the “half-life.” So, in two half-lives, or 11,460 years, only one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years.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.Accordingly, carbon dating carefully applied to items from historical times can be useful.
However, even with such historical calibration, archaeologists do not regard C produced and therefore dating the system.
Carbon has unique properties that are essential for life on Earth.
