What is carbon dating and how does it work
If this water vapor did exist in the past, then it would have effectively shielded the atmosphere from much of the cosmic radiation.This shielding would have drastically reduced the amount of Carbon-14 produced.In nature, all systems are open regardless of what evolutionists say in protest. As no two people have exactly the same DNA, individual plants and animals vary in their physical and genetic makeup.
The Carbon-14 dating method was introduced by Dr. Libby (1908-1980) at the University of Chicago in 1949. Carbon-12 is the normal stable isotope of Carbon (99% of all Carbon), which is the basic building block of organic life forms.
That means that starting with one pound of 100% Carbon-14, half of it would decay in 5,730 years, leaving 50%, or half a pound.
Then, in another 5,730 years, a second decay period would occur, leaving one quarter of a pound.
on July 16, 1945, and the subsequent above ground testing between 19, caused a rise in neutrons which in turn increased Carbon-14 concentrations around the world.
In a similar way, solar cosmic radiation fluctuates and would cause a fluctuation in the amount Carbon-14 being produced at any one an ongoing process.
