You have the technique and half life right but the upper limit is 60,000 years.Jenspm wrote:
well, it's been a few years since I did this in school, but anyway. The carbon-14 method of gauging age is done my measuring the amount of Carbon-14 left in the item. We know how quickly it decreases, and thus we're able to track back to around the time it died. The half-life of carbon-14 (ie the time it takes to half) is 5730 years. It is therefore almost down to a quarter after 10k years, so I think shifty's number of 10k is quite a bit off. Still, the point is there.Uzique wrote:

why the fuck would a rigorous and empirical scientific method work up to 10,000 years, and then suddenly become whack pseudo-science?
you christians are fucked up
To take an easy number, 57300 years from now, the percentage is down to 0.098%, and understandably the gauging becomes more difficult and impossible to get accurate.
The carbon deteriorates into N-14 which escapes the sample so you just have the carbon half life to go by.
