Carbon dating the shroud
Not only can scientists and historians not reproduce the image using medieval technologies, they can’t reproduce it with modern technology.Italian scientist Paolo Di Lazzaro tried for five years to replicate the image and concluded that it was produced by ultraviolet light, but the ultraviolet light necessary to reproduce the image “exceeds the maximum power released by all ultraviolet light sources available today.” The time for such a burst “would be shorter than one forty-billionth of a second, and the intensity of the ultra violet light would have to be around several billion watts.” 2) The 3D capabilities of the image. The wounds of the crucified man are all consistent not only with Roman crucifixion, but the details of Jesus’ particular crucifixion – the scourging, the crown of thorns, no broken bones, and the wound in the side.It is not burned on in a conventional heat application method.Instead it is seared on to the cloth with a technology that has yet to be explained.Dust from the area of the image by the knees and feet is from the area around Jerusalem. The Shroud details are perfectly consistent with first-century Jewish burial customs.There are even microscopic traces of the flowers that would have been used in the burial-flowers that grew locally and were known to be used for burial.In addition, traces of the spices used for Jewish burial have been discovered. The bloodstains on the Shroud are real human blood, not paint.
This technology uses infra-red light and spectroscopy to measure the radiation intensity through wavelengths, and from these measurements a date can be calculated.
It is, they believe, the burial cloth of Jesus Christ.
