In the movies, scientists use “carbon dating” to determine the age of ancient artifacts and dinosaur bones. But what is the real science behind carbon.
Critics suggest that coal could have had carbon fixed by bacteria or fungus in the coal Talk Origins. Conclusion Radiocarbon dating relies upon the assumption that C production in the atmosphere has been constant during the history of life on earth.
Radiocarbon is therefore being used for dating when we simply have no way to determine what the conclusions carbon dating of C production were in the past. It is based upon the assumption that the rate of the formation of carbon 14 in the upper atmosphere is equal to the rate of decay. He says everyone knows that the earth is over 30, years old so carbon 14 must be in equilibrium.
If allowance is made for Libby's erroneous assumption, the corrected carbon 14 dates come back to within the last years. Carbon 14 analysis, as in the case of other dating methods, does not really determine anything about age; it simply tells you the amount of carbon 14 found in a substance.
Carbon 14, formed in the upper atmosphere, filters down into the plants, and one eats either plants or things that have eaten plants. Therefore, a certain amount of carbon 14 is trapped in your body and bones. Scientists measure how much is present and, based on the half life of carbon 14, they project back in time to see how long you must have been around.
