Chate the girls - How exact is carbon dating

‘Plato and many others of the philosophers, since they were ignorant of the origin of all things, and of that primal period at which the world was made, said that many thousands of ages had passed since this beautiful arrangement of the world was completed … The Greeks borrowed some of these ideas from the Babylonians, Egyptians and Hindus, whose philosophies extended back centuries before.

For example, one Hindu belief was that Brahman (the Universe) spontaneously evolved by itself like a seed, which expanded and formed all that exists about 4.3 billion years ago.

The X-axis of the graph is the ratio of in a closed system over time.

It is not easily explained, in the general case, in any other way.

In many cases, there are independent cues (such as geologic setting or the chemistry of the specimen) which can suggest that such assumptions are entirely reasonable.

However, the methods must be used with care -- and one should be cautious about investing much confidence in the resulting age...

(The range of uncertainty varies, and may be as much as an order of magnitude different from the approximate value above.

It depends on the accuracy of the measurements and the fit of the data to the line in each individual case.) For example, with Rb/Sr isochron dating, any age less than a few tens of millions of years is usually indistinguishable from zero.Isochron dating requires a fourth measurement to be taken, which is the amount of a different isotope of the same element as the daughter product of radioactive decay.(For brevity's sake, hereafter I will refer to the parent isotope as ).The early Christian Church Fathers constantly argued with the pagans about the age of the earth, or about the age of civilization.They were unanimous that God had created the earth less than 6,000 years before they wrote.For further information on fitting of lines to data (also known as regression analysis), see: Note that the methods used by isotope geologists (as described by York) are much more complicated than those described by Gonick.
