When we look at sand in an hourglass, we can estimate how much time has passed based on the amount of sand that has fallen to the bottom.
Radioactive rocks offer a similar “clock.” Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate.
Think of it like a teaspoon of cocoa mixed into a cake dough—after a while, the ‘ratio’ of cocoa to flour particles would be roughly the same no matter which part of the cake you sampled.
The fact that the N doesn’t matter in a living thing—because it is constantly exchanging carbon with its surroundings, the ‘mixture’ will be the same as in the atmosphere and in all living things.
Certainly if there was such a Flood, as we maintain from several other lines of evidence and reasoning, most living things would have perished, and so we would expect a ‘cut-off’ point at this time.
Libby knew that C was entering and leaving the atmosphere (and hence the carbon cycle).
Based on these observations and the known rate of radioactive decay, they estimate the time it has taken for the daughter isotope to accumulate in the rock.
However, unlike the hourglass whose accuracy can be tested by turning it upside down and comparing it to trustworthy clocks, the reliability of the radioactive “clock” is subject to three unprovable assumptions.
has upset the natural carbon balance by releasing huge quantities of C ratio was like before the industrial revolution, and all radiocarbon dating is made with this in mind.
How do we know what the ratio was before then, though, say thousands of years ago?
Remember that this correction is based on In any case, even the incorrect ‘uniform’ model has given, in many cases, serious embarrassment to evolutionists by giving ages which are much younger than those he expects in terms of his model of earth history.
