why is carbon dating still used with all its' inconsistent variables?

Question

problem 1: C-14 and C-12 levels are "assumed" to be constant through out all years teasted, no variations for thousands of years
problem 2: it's assumed that the body tested would have the same ratio of the isotopes as found in air (factors include climate etc.)
problem 3: though it is corrected for the variation of the magnetic field at one point, is the change in the field consrtant and C-14 relation to it?

Answer 1

Because it is accurate up to about 60,000 years.

If you already have the answer you want to believe, why are you asking? Or, for that matter, if you have a more accurate method, go get your Nobel... that's how Willard Libby got his.

Answer 2

Gee, why don't you add the assumption that physics is the same at all points in the universe and throughout time (excepting at the beginning of the big bang? That all scientists are honest and all scientific tests are conducted under perfect conditions.

Why not assume the reverse, that no test results are reliable? That would lead to a much more interesting scientific discourse, wouldn't it!

Answer 3

It,s still the best we have because carbon is present in all organic matters and so is carbone isotopes. Living matter stop producing Carbone isotopes and thus isotope concentration is decayed radioactively. You need those isotopes in the investigated matter to compare their concentration with C-12 & C-14 levels.Carbon dating is not perfect but it still can give you a good idea.

Answer 4

So what you're really saying is that a big dude in the sky created the earth 6,000 years ago, and that something that has proven itself to be worthy after unbiased scientific scrutiny is false because of a margin of error including a few thousand years, when each of these dates are taking us back millions of years ago? Creationist zionist friend, answer me this. The andromeda Galaxy is 6,000,000 light years away, meaning it takes 6,000,000 years for us to see the light that comes from it. How can we see it if creationist scum are correct?

Answer 5

Carbon dating is used because just about everything contains carbon, and enough carbon is C-14 to make carbon dating possible in many items.
Using other forms of dating is only possible if the subject matter contains the right element(s).

Answer 6

It may be innacurate, but not to the extent that some want it to be. If we date something as 2 million years old...I'd find it a hard stretch to say it was any younger than 6000 years let alone younger than 1.5 million.

Answer 7

Because some people think the word theory means proof. They use one theory as proof of another theory. never mind that it's all just guest work.

Answer 8

No one said it was perfect. Until a better method is proven, then it will have to do.
