Bob,
I've just solved a mystery. The reason I couldn't see Jarrah's thread on the NVIDIA video, (YouTube), is because I blocked him a long time ago. I didn't block him on my Debunx channel, though. So I can see the thread that way, but since he had blocked that account, too, that means he can't see any of my comments.
Apparently sjoeroever and Jarrah can see each other's posts, so I asked him to pass on the information about the American Scientist diagram as well as briefly what you heard from Dr. Odenwald. There's no way to know if he's gotten that information until sjoeroever tells him and he responds.
If anyone here knows they can contact Jarrah, could you please pass the information on to him about both of these issues?
