Radiocarbon (Carbon 14) Dating Biggest Mistake In early 2005 The American Chemical Society website quoted Raymond Rogers, a Fellow of the Los Alamos National Laboratory: "The observations do not prove how the image was formed or the 'authenticity' of the Shroud. There could be a nearly infinite number of alternate hypotheses, and the search for new hypotheses should continue."
And, at about the same time, Philip Ball, who had been the Senior Editor for Physical Sciences of the Nature Journal of Science when Nature published the results of the 1988 carbon 14 dating of the Shroud, discussed the new studies that challenged those tests, in the journal's online edition. He paraphrased Rogers: "It is, [Rogers] says, between 1300 and 2000 years old. Let's call it somewhere around the middle of that range, which puts the age at about 2,000 years. Which can mean only one thing . . ."
Why all this attention to the Shroud of Turin Carbon 14 testing? Raymond Rogers had just published an article in the peer-reviewed scientific journal Thermochimica Acta (Volume 425 pp. 189-194) that proved that the 1988carbon 14 dating in was incorrect. And simultaneously, John L. Brown, formerly Principal Research Scientist at the Georgia Tech Research Institute's Energy and Materials Sciences Laboratory at the Georgia Institute of Technology, independently confirmed many of Rogers’ findings.
Along with those findings, other information came to light that demonstrated that the radiocarbon dating of the Shroud of Turin may have been the biggest carbon 14 dating mistake ever made.
As if that was not enough, Philips, who understood the fact, wrote in Nature, "It is simply not known how the ghostly image of a serene, bearded man was made," underscoring the other fact about the Shroud of Turin. Not only does no one know the real age of the cloth, no one knows how the images were made. They were not painted, as Philips points out. Nor were they some type of medieval photography. That, Philips thought was absurd.
If we rely only on peer-reviewed science journals we know this: The Shroud of Turin is at least 1300 years old. The images are a darkening of an otherwise clear starch and polysaccharide coating thinner than most bacteria. The Shroud of Turin is not medieval.
