Assumptions used in carbon dating

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

Efforts to salvage carbon dating are many and varied, with calibration curves attempting to bring the C-14 "dates" in line with historical dates, but these produce predictably unreliable results.

Thus, no one even considers using carbon dating for dates in this range.

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

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.

It cannot be used to date volcanic rocks, for example.

The rate of decay of N in 5,730 years (plus or minus 40 years).

Accordingly, carbon dating carefully applied to items from historical times can be useful.Thus carbon dating says nothing at all about millions of years, and often lacks accuracy even with historical specimens, denying as it does the truth of the great Flood.In reality, its measured disequilibrium points to just such a world-altering event, not many years ago.It is only useful for once-living things which still contain carbon, like flesh or bone or wood.Rocks and fossils, consisting only of inorganic minerals, cannot be dated by this scheme.

Thus the ratio of stable C-12 to unstable C-14, which is known in today's open environment, changes over time in an isolated specimen. As long as the tree lives, it absorbs carbon from the atmosphere in the form of carbon dioxide, both C-12 and C-14.

    Online dating isn't something to fear even if you haven't dated for years I've been dating pretty much since I was 49. (I'll let you do the math -- I don't like saying my age out loud.) The following is stated neither with gushing pride nor cowering shame: During those past 13 years, I've had more than 1,000 dates with more than 300 different women. There are things men and women can take going into this dating abyss, but let's start with advice for you (older) guys, in reverse order of importance • Funny is good. Cynical and bitter might work if you're a dark and complicated graduate student.
