Carbon dating innacurate how to write an online dating profile

Any further back than that and your standard deviations go way up.Also, C-14 years do not correlate with actual calendar years, since the amount of C-14 isotopes in the atmosphere has fluctuated in the past, and the dating method assumes it was constant.Of course C-14 would never be of any use for dating dinosaur bearing deposits, unless you want everything to date to around 40,000 years!

We usually hear of Carbon 14 dating, which is very important in archaeology.

The Greeks had the "great year" of 24,500 years, based on the precession of the equinoxes.

The time-scale of the fundamentalist or Creationist Judeo-Christian is based on a word-for-word reading of the first book of the Bible, and assumes a total age of the earth and the cosmos of a mere 5 or 6,000 (some Creationists allow 10,000) years.

Tree ring data (dendrochronology) can be used to even out this inconsistency, however the oldest trees used for calibration are in the order to about 6,000 years old, so any further back than that and you can't correct your dates (although there are reportedly some preserved huon pines in Tasmania that could take this right back to 30,000 years or so, if anyone wants to spend half their life time counting tree rings).

Even if dates are corrected with tree ring data they are still not considered calander years, but rather radiocarbon years.
