I'm not anywhere close to being a scientist/astronomer, nor do I have the capability or interest in studying it, but i've met Robert Sungenis in person and talked to him about all sorts of topics, both science and non-science. He's extremely down to earth and seems like a rational, level-headed guy. I'm not saying his reasons support or fail-to-support flat earth, all i'm saying is he seems like he's a good catholic. Whatever that's worth.
