Carbon dating seal
Carbon dating is used to work out the age of organic material — in effect, any living thing.
The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
They then left Babel and radiated in all directions, forming new civilizations around the world.
New-Earth creationism is mainly promoted by people who believe that the Bible authors were inspired by God to write text that is inerrant -- free of error.
But even he “realized that there probably would be variation”, says Christopher Bronk Ramsey, a geochronologist at the University of Oxford, UK, who led the latest work, published today in Science.
Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.
The problem, says Bronk Ramsey, is that tree rings provide a direct record that only goes as far back as about 14,000 years.
As a rule, carbon dates are younger than calendar dates: a bone carbon-dated to 10,000 years is around 11,000 years old, and 20,000 carbon years roughly equates to 24,000 calendar years.New-earth creationists obviously cannot accept the accuracy of the C-14 dating method.For example: Scientists have dated a female figurine commonly called the Venus of Willendorf or the Woman of Willendorf to 24,000 to 22,000 BCE.But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii; work that won Willard Libby the 1960 Nobel Prize in Chemistry.
