He claimed that it was capable of dating animal, plant and human remains of fairly recent origin. As they say on Star Trek, we are all carbon based units.Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.
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.Carbon-14 decays to a zero amount in 250,000 supposed years after its production.It is incapable of yielding dates in the millions of years.The Carbon-14 Dioxide is then utilized by plants during their normal metabolism.Animals and humans who eat these plants take the Carbon-14 into their systems just as they would Carbon-12 Dioxide.In high school biology courses they often teach about the inevitable failures of closed systems by taking an aquarium and placing snails, plants and a bowl of water inside; then sealing the aquarium so that no air may get in or out.
The idea is that snails produce carbon dioxide which is utilized by the plants, the plants produce oxygen which utilized by the snails. Of course, it doesnt take long before the experiment fails in death for all those in the aquarium.
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.
Even a sealed aquarium has sunlight, X-rays, Gamma Rays, ultra-violet light, etc. These variations cause individual organisms to absorb or reject Carbon-14 at different previously published radiocarbon dates must be corrected or mathematically weighted to correct the dates from the published dates to the actual dates.50,000 years it may be seen that the method is based on many false assumptions.
As the magnetic field decreases, more cosmic radiation penetrates the earths atmosphere and this causes a slow long-term increase in Carbon-14 production.
These factors combine to cause fluctuations in the Carbon-12/Carbon-14 ratios found in plant, animal and human materials.
Besides the aforementioned items, the amount of cosmic radiation in the past, and in particular the amount reaching the atmosphere, may have been dramatically different.
