Oh don't get you panties in a twist!..I cut an pasted because I didn't want to post the whole link..(being as the experts in here don't even look at them)..so here:

I thought for a moment you might be remotely interested, because co-incidentally, the image on the shroud, as tested by the scientists, was not made by 'painting' or absorption of a liquid, but rather by 'radiation', either by heat or light or both..and being as you brought up 'thermodynamics' that you could check it out yourself, instead of playing 'follow the leaders'..who happen to be the three blind mice...or rats, as you may prefer...and stop acting like lemmings!!

...or is that too scientific for ya'?
