radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.

How do we know how old a fossil is we use carbon as every living being has carbon carbon dating also known as radiocarbon dating is a method of estimating the age of carbonbearing materials up to 60000 years old.

4 geological dating of igneous rocks certain elements with very long halflives can be used to date the geological age of igneous rocks and even the age of the earth has a halflife of 13 x 10 9 years it decays to form if the argon gas is trapped in the rock the ratio of potassium40 to argon40 decreases over time and the ratio can be used to date the age of rock formation ie from.

carbon dating is used to determine the age of biological artifacts up to 50000 years old this technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.

To demonstrate that the rates of decay of unstable nuclei can be measured that the exact time that a certain nucleus will decay cannot be predicted and that it takes a very large number of nuclei to find the rate of decay this is the second lesson in a threelesson series about isotopes.

The following material has been taken from a sheet entitled several faulty assumptions are used in all radiometric dating methodscarbon 14 is used for this example which was put out by dr hovind dr hovind r1 the atmospheric c14 is presently only 13 of the way to an equilibrium value which will be reached in 30000 years this nullifies the carbon14 method as well as demonstrating.

Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale even if they cannot provide a naturalistic mechanism they appeal to the fact of evolution by which they mean an interpretation of earth.
