Sign from God board member, Shroud author, and researcher Mark Antonacci has responded to the widely reported blood flow study in the mainstream media that proclaimed the Shroud was "fake."
Here is an excerpt from his analysis:
An Unrealistic Approach and Analysis of the Blood Flows on the Shroud of Turin
A recent paper by Matteo Borrini and Luigi Garlaschelli titled “A BPA Approach to the Shroud of Turin” was recently published in the Journal of Forensic Sciences1. This paper contains the bloodstain patterns from two sets of experiments in which:
1.) blood from an overhead bag was released through a small thin tube located at the back of the wrist of one of the authors, and which
2.) blood flows were made on a plastic mannequin by pressure being applied on a small sponge soaked in blood.
From these experimental results, which differ from comparable blood flows on the Shroud of Turin, the authors conclude the blood flow patterns on the Shroud are unrealistic and indicate they were the result of artistry or were faked. In this article, I will briefly explain how both sets of experiments are flawed in several respects, how the blood flows on the Shroud are quite realistic, and how the authors’ conclusions are necessarily flawed. All of the comments that I will make about the blood marks on the multiply-wounded crucifixion victim wrapped in the Shroud are supported by decades of research by numerous pathologists, physicians, anatomists, battlefield surgeons, scientists and forensic experts cited throughout both of my below books.
