Shroud researchers ARE in favor of new carbon dating. However the Shroud is the property of the Pope. The scientists do not have the final say. An unauthorized C-14 test was performed on a thread several years ago. Results were 1st Century. . . but because it was unauthorized, the results are unofficial and unpublishable but just talked about.
However, you are wrong to state the 1988 C-14 test dating stands. It has been invalidated in peer-reviewed, published science which post-dates the tests. Invalidation means the date is just that. INVALID. It means nothing. Any one who chooses to cite it is biased and is NOT truthful or a true scientist. . . because it has been PROVED FALSE! To cite in light of that proof and the publication and peer-review, and confirmation by TWO independent researchers by other methods and published in two other peer-reviewed journals, make it absolutely proven and accepted.
The sad thing was that it was avoidable. The original C-14 test broke the well designed protocols designed by STURP to avoid this very issue and in fact took their single sample from the very area the STURP scientist all agreed SHOULD BE EXCLUDED because it was obviously chemically and physically different from the main body of the Shroud! The 1988 C-14 sample taking group were idiots.
Enlighten me, then, by posting links to these journal articles. Please post from reputable journals.
Face it: it has been 25 years, and if the carbon dating methodology was flawed, there has been ample time to redo it.
