More than a decade ago, Unbelievable? brought together two experts with very different conclusions about the Shroud of Turin—one of the most mysterious and debated Christian relics. Dr Alan Whanger, who devoted years to studying the Shroud, claimed to identify faint images and markings that point to its origins in 1st-century Israel. Meanwhile, Hugh Farey, editor of The Catholic Shroud of Turin Newsletter, has spent decades critically examining the Shroud literature and argues the evidence strongly supports a medieval origin.

Latest Developments (2020s):

Since that episode aired, there have been further scientific investigations and renewed debates. In 2017, Italian researchers used new dating techniques (notably, Raman spectroscopy and FTIR analysis) to argue for a possible 1st-century origin—challenging the 1988 carbon dating that placed the Shroud in the 13th or 14th century. However, these newer findings remain controversial and have not overturned the scientific consensus. The Shroud continues to spark interest not only among believers and sceptics, but also in fields as diverse as history, forensic science, and art restoration.
