The Shroud of Turin, a piece of cloth with what appears to be a man’s face on it, has long been exploited (although not officially) to be the burial shroud of Jesus.
Let me just say for the record: I doubt it highly.
Lots of tests have been done on the shroud to determine its origin and possible date. The latest theory is that the shroud is the result of an earthquake.
Apparently, “neutron emissions from an ancient earthquake that rocked Jerusalem could have created the iconic image, as well as messed up the radiocarbon levels that later suggested the shroud was a medieval forgery.”
“These neutron emissions could have interacted directly with nitrogen atoms in the linen fibers, inducing chemical reactions that created the distinctive face image on the shroud, the scientists say.”
I don’t know, sounds shaky to me.
