Most of this world is still a mystery to me. I'm hoping that Steemit will help bring people together to discuss such matters. But, I do agree with your logic --the moon would have to be within the dome (our atmosphere).

Other things I'm curious about is what kind of substance the dome is made out of? I would try to go to the edge (Antarctica) but that might get me arrested for 'trespassing' or die from the elements. Just like a real-life Truman Show. The following video will have you believe the substance is some sort of liquid?
