Defense carbon dating

There are two major assumptions that are impossible to prove or disprove. Based upon the Big Bang theory as well as the theory of evolution, most scientists (and therefore the general public) believe that the universe and the world are billions of years old.This assumption allows for C in the environment is mostly constant.The unstable carbon-14 gradually decays to carbon-12 at a steady rate. Scientists measure the ratio of carbon isotopes to be able to estimate how far back in time a biological sample was active or alive.

In several documented situations when carbon dating ran contrary to common scientific assumptions, the results were only an anomaly if the world were billions of years old.

Because the cosmic ray bombardment is fairly constant, there’s a near-constant level of carbon-14 to carbon-12 ratio in Earth’s atmosphere.

Organisms at the base of the food chain that photosynthesize – for example, plants and algae – use the carbon in Earth’s atmosphere.

Aboveground nuclear testing almost doubled the amount of carbon-14 in the atmosphere. The black arrow shows when the Partial Test Ban Treaty was enacted that banned aboveground nuclear tests. A special kind of radiocarbon dating: Bomb radiocarbon dating.

As we mentioned above, the carbon-14 to carbon-12 ratio in the atmosphere remains nearly constant.

Here’s an example using the simplest atom, hydrogen. Carbon-14 is an unstable isotope of carbon that will eventually decay at a known rate to become carbon-12.
