Carbon 14 dating disproved
There are two major assumptions that are impossible to prove or disprove. Based upon the Big Bang theory as well as the theory of evolution, most scientists (and therefore the general public) believe that the universe and the world are billions of years old.
This assumption allows for C in the environment is mostly constant.
Because it is radioactive, carbon 14 steadily decays into other substances.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.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.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.
Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.
Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.
