In the article you pointed to, it refers to the NASA tests that the image is tri-dimensional. You may or may not know what it means because they use "tri" in lieu of three.
The High Tech NASA test on the Shroud found it to be 3-dimensional image.
It is my theory that the Shroud image was formed by the energy of the "Resurrection" -- the brilliant light that blinded the guards at the Resurrection of Jesus Christ.
Further, the article states the Shroud image is an image and not something from the wounds and beatings forming an image. But since the skin/flesh of Jesus touched the Shroud, the Shroud contains blood, as stated in the article.
Lastly, the Shroud was damaged in a fire, and some parts of the cloth was re-woven. It may have been by error that the church gave science a part of the shroud that had the re-woven threads, and that would really foul up the carbon dating. BUT MAYBE THE CHURCH OFFICIALS THOUGHT SCIENCE WOULD CATCH THAT.
We must remember how stupid scientists are, and how smart simple minds can be some time (with the inspiration of God).
I know in my life when God is working through me, I do great. When I try to do something, I really screw up. And this is from someone with an IQ of 130 or higher.
