Creation science and carbon dating
But, as C-14 continuously decays, it is also continuously being replaced by new C-14 being formed.
How carbon-14 enters an organism Most C-14 will combine with oxygen to produce radioactive carbon dioxide (C-14 O-2).
For this reason, I will have to bite the bullet and accept that it is reasonable to assume the decay rate is constant (even though I give this assumption, this doesn’t mean the decay rate is constant.
Rather I am conceding due to no current evidence for the contrary).
Many people also don’t realize that carbon dating (along with other radioactive dating methods) is based upon unverifiable assumptions.
Most authorities agree that C-14 decays at such a rate that half of it will be gone in approximately 5,730 years.
This means if a specimen contained, say, a pound of C-14 (to make things understandable), in 5,730 years, half of it will be gone, and in another 5,730 years, half of the remaining C-14 will disappear.
After about 8 half-lives, the remaining amount of C-14 (if there is any remaining) is too small to be measured.
For this reason, it is simply impossible for carbon dating to give dates as old as millions of years. Closed systems, void of any contamination and without loss of the parent element (C-14) or daughter element. Known amounts of parent and daughter elements present from the beginning. If the decay rate of C-14 were not always constant, then this would be devastating to the technique's credibility.
