Carbon 14 dating unreliable autistic dating uk
The C-12 is a very stable element and will not change form after being absorbed; however, C-14 is highly unstable and in fact will immediately begin changing after absorption.Specifically, each nucleus will lose an electron, a process which is referred to as decay.It disintegrates at a measured rate into calcium and argon.Similarly, the radioactive element uranium decomposes into lead and some other elements.At its most basic level, carbon dating is the method of determining the age of organic material by measuring the levels of carbon found in it.Specifically, there are two types of carbon found in organic materials: carbon 12 (C-12) and carbon 14 (C-14). The lowest age defended on a scientific basis is in the 6 to 10 thousand year range.Evolutionism, of course, requires billions of years to support the plausibility of life's emergence and of subsequent Evolution from “amoeba” to man.
Scientists have proposed numerous age estimation methods.
There is no absolutely reliable long-term radiological 'clock'." "The age of our globe is presently thought to be some 4.5 billion years, based on radio-decay rates of uranium and thorium.
Such ‘confirmation’ may be shortlived, as nature is not to be discovered quite so easily.
"It is obvious that radiometric techniques may not be the absolute dating methods that they are claimed to be.
Age estimates on a given geological stratum by different radiometric methods are often quite different (sometimes by hundreds of millions of years).

Age estimates which are obviously wrong or contradictory are sometimes produced.
