Is that a flatearther? Sounds like he’s saying his dome is made of glass, and the sun is an iron light??
Looking into the site, looks like he’s a concave earthist, using this “stuff bends in curves so everything looks convex” idea.
Don’t get where he is putting his sky glass, though. I almost think to him the sun an actual enourmous modern-day lightbulb, and fulminites are pieces of it chipping off (because he believes them to be glass meteorites)
