From The Guardian:
Many would argue that, even if the shroud could be proved to be the burial cloth of the man named Jesus who was crucified 2,000 years ago, that doesn’t amount to proof of his resurrection, the central tenet of Christian belief. “The carbon dating could show it was definitely from the time of Christ, but it’s still a stretch to go from that to seeing it as proof that he rose from the dead,” says Richy Thompson of Humanists UK. “Some people believe that, yes, Jesus was a real person, and we know crucifixion was a thing in those times, and Pontius Pilate is a well-documented historical figure.
“What many non-religious people would say is, where is the evidence? Because if you’re going to make extraordinary claims, you need strong evidence to back it up. And the fact that people believe [in the resurrection] is not in itself evidence that it actually happened.”
Rolfe is unperturbed: he says the image on the cloth seems to have come from a massive burst of radiation, emitted in a fraction of a second.
When it comes to the carbon dating, he’s certainly not alone in his scepticism. Barrie M Schwortz, a photographer who documented the shroud in 1978, says “murky” would be a good word to describe the events of 1988.
“Today there are at least six peer-reviewed scientific articles that challenge the results of the carbon dating,” he says. In his view, the players involved were in a hurry to get the job done, because they wanted to get carbon dating on the map. “Those tests made it a household name, and today it’s used widely in archaeology,” he says. “I’m Jewish, so I don’t have a horse in this race, but I’ve come to believe it’s the authentic burial cloth because I’ve looked at the science.”
The British Museum is less willing to get involved this time around. “Any current questions about the shroud would be best put to those who currently care for it in the royal chapel of the cathedral of Turin,” a spokesperson said. (Read more.)
From Aleteia:
In his report, published on the website of Italy’s Department of Chemical Sciences and Materials Technologies, de Caro pointed out a few flaws with dating by Carbon-14 analysis. He noted that textile samples can easily become contaminated with substances that could skew its results. He wrote:
“Molds and bacteria, colonizing textile fibers, and dirt or carbon-containing minerals, such as limestone, adhering to them, in the empty spaces between the fibers that at a microscopic level represent about 50% of the volume, can be so difficult to completely eliminate in the sample cleaning phase, which can distort the dating.”
De Caro noted that fabric can even become enriched with new Carbon-14 samples. At this point, it would become hard to identify if carbon dating measured the original fabric, or a layer of carbon that was accumulated over time. (Read more.)
