The article is in straightforward language and the non-technical reader could profitably work through it., we find that this ration is the same if we sample a leaf from a tree, or a part of your body.Remember that this correction is based on measurable scientific data, not on any creationist preconceptions.We need to consider two other effects: 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.
However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.Imagine the same tank, this time it is not yet full and the top tap is flowing more quickly than the bottom one is leaking out—this gives you a way of measuring how long ago the whole system was ‘switched on’ and it also tells you that that can’t have been too long ago (see diagram above).Libby knew that if these figures were correct, it would mean that the atmosphere was young, so he dismissed the results as being due to experimental error!Consider this—if a specimen is older than 50,000 years, it has been calculated, it would have such a small amount of C that for practical purposes it would show an ‘infinite’ radiocarbon age. Readers are referred to this article for other interesting conclusions about these dates.So it was expected that most deposits such as coal, gas, petrified trees, etc. In fact, of 15,000 dates in the journal to 1968, only three were classed ‘un-dateable’—most were of the sort which should have been in this category.
