Assumptions used in carbon dating
Due to so many different kinds or radiometric dating in use (i.e Radiocarbon dating, also called carbon dating, Potassium-argon dating, Uranium-lead dating, Uranium-thorium and Rubidium-strontium dating), all of which concur with each other when dating objects, it is extremely unlikely that all of them are wrong in the exact same way.
Therefore, support for radiometric dating is virtually universal in the scientific community.
Radiometric dating requires careful analysis and control over the isotopic mix of atoms in the original sample, as well as careful analysis and control of factors (e.g.
chemical changes) that might have changed the amounts of the various elements in the sample during the decay interval.
This has given rates for supernovae as distant as 169,000 light years which are consistent with those measured today.
Radiometric dating is mostly used to determine the age of rocks, though a particular form of radiometric dating—called Radiocarbon dating—can date wood, cloth, skeletons, and other organic material.
Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object.
