Christ Dunn is associated with a seperate research team that did the guage and scan tests. He's a engineer and precision tooling and worked with NASA aerospace. A pioneer in precision tooling and published plenty of papers.
Dr. Max Fomitchev-Zamilov is a physicists and engineer with Penn State Uni. Published plenty of papers.
I also mentioned other scientists that worked with Karoyl

Theres more but I can't be bothered having to address ad hominems.
Heres the thing. Your scrutinising these researchers while its ok that a few people on a social media platform can make objections and claims the research and testing is all wrong without any formal credentials or published work and its ok. The same level of scrutiny is not applied. So long as they are of the opinion that the researchers are wrong they don't need to be questioned. Their opinion is correct automatically.
I don't think thats consistent or fair. Like I said when a skeptic or objector does their own tests and research and then published their work refuting these researchers I will go with the researchers. Three independent published tests and findings all saying the same thing regardless of peer review is better than objections on a social media platform.
