Could carbon dating be wrong
Let's say initially every radioactive element was "exploded" into existence from pre-existent elements.
None of these early faster half-lives would be the same as they are today.
When each of these elements, uranium, potassium, radium etc.
were switched on, it would only be natural for them to behave according to their individual properties, eventually acquiring stable half-lives of decay, at different rates.
Libbey knew that atmospheric carbon would reach equilibrium in 30,000 years.
Because he assumed that the earth was millions of years old, he believed it was already at equilibrium.
Carbon dating makes an animal living 4 thousand years ago (when there was less atmospheric carbon) appear to have lived thousands of years before it actually did.
A great book on the flaws of dating methods is "Radioisotopes and the age of the earth" (edited by Larry Vardiman, Andrew Snelling, Eugene F. Published by Institute for Creation Research; December 2000) Dating methods are based on 3 unprovable and questionable assumptions: 1) That the rate of decay has been constant throughout time. That the isotope abundances in the specimen dated have not been altered during its history by addition or removal of either parent or daughter isotopes 3) That when the rock first formed it contained a known amount of daughter material ("Radioisotopes and the age of the earth" pg v) We must recognize that past processes may not be occurring at all today, and that some may have occurred at rates and intensities far different from similar processes today.
Each would probably arrive at equilibrium at different times.Many people are under the false impression that carbon dating proves that dinosaurs and other extinct animals lived millions of years ago.What many do not realize is that carbon dating is not used to date dinosaurs. Carbon dating is only accurate back a few thousand years.What would happen if a dinosaur bone were carbon dated?- At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method.
