This is the
only scientific data that contradicts the authenticity of the Shroud, and recent research suggests that the carbon dating could have been thrown off by fire damage to the Shroud.
The evidence in favor of the Shroud's authenticity is so overwhelming in fact, that many scientists who have undertaken the task of disproving the Shroud's authenticity have ultimately converted to Christianity or Catholicism.
What debunks the shroud is also the image. It looks like a caucasian male from the 12th century, not a Hebrew male, which Jesus was. Also, Scripture says,
Isaiah 52: 13 Behold, my servant shall deal prudently, he shall be exalted and extolled, and be very high. 14 As many were astonied at thee; his visage was so marred more than any man, and his form more than the sons of men: Jesus's face would be unrecognizable to be a man. He was beaten to a pulp, his tongue would be swollen from dehydration.
The first person in the tomb after the resurection was Peter, he saw the burial clothes, but he never mentions an image on them. Jesus didn't stay long enough in the burial cloth for any thing to happen in it.
