Radio carbon dating inaccuracies Adult chats throught aim
Since it is chemically indistinguishable from the stable isotopes of carbon (carbon-12 and carbon-13), radiocarbon is taken by plants during photosynthesis and then ingested by animals regularly throughout their lifetimes.When a plant or animal organism dies, however, the exchange of radiocarbon from the atmosphere and the biosphere stops, and the amount of radiocarbon gradually decreases, with a half-life of approximately 5730 years.The results can be as much as 150 million years different from each other! They then pick the date they like best, based upon their preconceived notion of how old their theory says the fossil should be .So they start with the assumption that dinosaurs lived millions of years ago, then manipulate the results until they agree with their conclusion. So why is it that if the date doesn't fit the theory, they change the facts?What would happen if a dinosaur bone were carbon dated?- At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method.
There is a greater part of man’s unwritten past that archaeology has managed to unravel.Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences.
