The model of radiocarbon dating which Libby developed, using his incorrect ‘uniform’ assumption, must therefore be corrected to fit the facts about C to start with, so they have an even greater error.In other words, the further you go back, the more you have to shrink the radiocarbon dates to make them fit the facts.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.
Obviously this only works for things which once contained carbon—it can’t be used to date rocks and minerals, for example. We obviously need to know this to be able to work out at what point the ‘clock’ began to tick.We’ve seen that it would have been the same as in the atmosphere at the time the specimen died. Do scientists assume that it was the same as it is now? It is well known that the industrial revolution, with its burning of huge masses of coal, etc.In other words, going into the past, we should reach a period of time in which there is a sharp reduction in the number of specimens compared to the period just older than that, and as we went forward in time, we would expect a gradual buildup, as plant and animal populations recovered their numbers. Using the 15,000 published dates previously mentioned after adjusting them as described, he grouped them into 500 year ‘blocks’ and found a dramatic drop-off about 5,000 years ago, with a worldwide distribution (, Ed. Radiocarbon dating, which is also known as carbon-14 dating, is one widely used radiometric dating scheme to determine dates of ancient artifacts.by Creation-Science Research Center) A question which could be asked after all this is: does radio-carbon, adjusted to fit the ‘non-uniform’ model, give any independent evidence of a worldwide catastrophe such as the Flood?
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. When a plant or animal organism dies, however, the exchange of radiocarbon from the atmosphere and the biosphere stops, and the amount of radiocarbon gradually decreases, with a half-life of approximately 5730 years.Because of this relatively short half-life, radiocarbon is useful for dating items of a relatively recent vintage, as far back as roughly 50,000 years before the present epoch.In discussions of the age of the earth and the antiquity of the human race, creationists often assail perceived weaknesses in radiocarbon dating. Morris, for instance, wrote, "Despite its high popularity, [radiocarbon dating] involves a number of doubtful assumptions, some of which are sufficiently serious to make its results for all ages exceeding about 2000 or 3000 years, in serious need of revision." [Morris2000, pg. Radiocarbon dating is based on the fact that the interaction of cosmic rays from outer space with nitrogen atoms in the atmosphere produces an unstable isotope of carbon, namely radiocarbon.Since it is chemically indistinguishable from the stable isotopes of carbon (carbon-12 and carbon-13), radiocarbon is taken by plants during photosynthesis and then ingested by animals regularly throughout their lifetimes.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.
