Oh, wow! This continues to amaze me! Spectral analysis, which is a part of what I do in my career, has CLEARLY shown those edits throughout those older manuscripts. Some of the original script is still legible, but ONLY through spectral analysis that can see what is invisible to the naked, human eye. I have read the science journals of those findings, and yes, they are credible. If you have a handfull of "scholars" who think themselves qualified to poo poo the work of their colleagues who have provided photographic evidence in journals of this claim for edits discovered edits...MANY edits.
But, hey, I don't have permission to send copies to anyone since they are heavily copyrighted and VERY large files, but they are out there willing to do their homework by gaining access to the right journal databases they can access with the right credentials, and see it all for themselves.
