–Appendix II: Radioactive Dating
It may sound like a dangerous form of courtship, but far from it: Every living thing continuously exchanges carbon dioxide through food and air, going in and out. But once the living thing dies, no more carbon going in — only out.
By literally counting how much carbon atoms (more precisely an unstable carbon isotopes known as carbon-14, but who’s being picky) decays, a time frame can be estimated. Willard Frank Libby got a Nobel Price for figuring that out.
So does sliced bread, but nobody got a Nobel forthat one.
But geologists are well aware of the final and most striking problem with using C14 Radiocarbon Dating: the measurable age limit is in the range of 60,000 years, when any measurable carbon as fled the dead object.
Obviously, amber doesn’t make the cut.
