Unlike common carbon (12C), 14C is unstable and slowly decays, changing it back to nitrogen and releasing energy. Ordinary carbon (12C) is found in the carbon dioxide (CO2) in the air, which is taken up by plants, which in turn are eaten by animals.
Carbon-14 is made when cosmic rays knock neutrons out of atomic nuclei in the upper atmosphere.
These displaced neutrons, now moving fast, hit ordinary nitrogen (14N) at lower altitudes, converting it into 14C.
The story we have all heard from movies, television, newspapers, and most magazines and textbooks is that dinosaurs lived millions of years ago.
According to evolutionists, the dinosaurs ‘ruled the Earth’ for 140 million years, dying out about 65 million years ago.
Familiar to us as the black substance in charred wood, as diamonds, and the graphite in ‘lead’ pencils, carbon comes in several forms, or isotopes.
One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or 14C, or radiocarbon.
