For example, if the atmosphere today is .0000756% C-14 it is assumed the plants have the same %.Once an animal dies he stops eating and breathing and begins to decay.Do they prove Evolution Theory and that the earth is billions of years old? Carbon-14 is a method of radiometric dating that was invented in 1947 by Dr. Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.
However, as we will determine, all radiometric dating methods are based on assumptions about events that happened in the past. Assumptions based on the belief that the future will be like the past.
So, a carbon atom might have six neutrons, or seven, or possibly eight, but it would always have six protons.
An “isotope” is any of several different forms of an element, each having different numbers of neutrons.
The illustration below shows the three isotopes of carbon.
The earth’s atmosphere has six gas layers and is about 100 miles thick. Radiation from the sun and from stars goes right through that magnetic field and hits the atmosphere producing Carbon-14.
