Carbon-14 dating is good and more accurate to measure steady things such as the age of fossils, rocks, mummies in their original tombs, etc. up to 50,000 years; but, it becomes harder to measure the things that have been manipulated various times, from time to time, after its original resting place. It is also difficult to Carbon-14 date things that have been subject to various climatic changes in different places, or if the item have been subject to fires, and all of these
are the case of the Shroud of Turin (The Shroud suffered several burnings during medieval times).
There are some difficulties with carbon dating. For example, nuclear tests or unusual solar weather can change the rate of production:
The Holy Shroud has suffered a portion of fires, or change of locations that have altered its Carbon-14, that’s why the date that some analyst have given as if it is from the “1200s or 1300s” in 1988 is invalid.
Many experts have stood by a 1988 carbon-14 dating of scraps of the cloth carried out by labs in Oxford, Zurich and Arizona that dated it from 1260 to 1390, which, of course, would rule out its used during the time of Christ.
The new test, by scientists at the University of Padua in northern Italy, used the same fibers from the 1988 tests but disputes the findings. The new examination dates the shroud to between 300 BC and 400 AD, which would put it in the era of Christ.
It determined that the earlier results may have been skewed by contamination from fibers used to repair the cloth when it was damaged by fire in the Middle Ages, the British newspaper reported. The cloth has been kept at the cathedral since 1578.
Also, The Shroud is not a “painting” as some people claim, evidence and scientific studies that have been made to the Shroud by renown experts (shown below and on the HC video), gives me the conclusion to believe that the image was caused by a miraculous radioactive fire or rays which emanated from Jesus’ body, perhaps at a fraction of a second, at the moment of His resurrection. Looked under the microscope, there is no paint between the threads, the fabric is slightly burned and those burnings formed the image, making it like a photo-effect on the Shroud, now these burnings are not usual burnings found on here earth, that’s why it is difficult to find out what it is, but, in reality, it was a miraculous type of burning. It was a miraculous type of fire or light. Once again, the cause that formed Jesus’ image on the Shroud of Turin is radioactive fire or rays which emanated from Jesus’ body at the moment of His resurrection. The image itself is proof of His resurrection, there is no other image on a burial cloth that have ever been formed by fire, and what’s more, that shows these types of unprecedented burnings to form an image, in the history of human kind, not other dead body has ever done it, this to me confirms the resurrection of Jesus Christ. The fires that formed the image did not destroyed the fabric because it is unparalleled, perhaps this occurred at hundredths of a second. The burnings that form the image are unusual and extraordinary. Now, of course that not all on the image are these types of burns, there are also blood samples from Christ’s lacerations all over His body which obviously marked the cloth as well.
Scientific researchers such as J. Jackson, G. Fanti, T. Trenn, T. Phillips, J.-B. Rinaudo among others have testified that there are not “paint” samples on the image, and that this claim must be cast-off.
Here is an interesting documentary by History Channel on the real face of Jesus using the Shroud of Turin which I highly recommend to all:
The life-like image was made by taking the image of the Turin Shroud and transforming it onto a 3D form to compose and inspire a CGI image of a detailed face.
