A single piece of linen, said to bear the markings of a crucified man,

is believed by millions to be the burial cloth of Jesus Christ himself.

For centuries, skeptics and believers alike have debated its origin.

But what happens when nuclear science enters the equation?

Bob Rucker is a nuclear

engineer with over 40 years of experience in nuclear analysis, radiation transport, and reactor

design. And he's applying that same scientific precision to the Shroud of Torin to uncover how

0:32.2

this mysterious image was formed and whether it really could be the burial cloth of Jesus Christ.

0:37.1

In fact, he's the only man
