Keep in mind one thing, JRoweSkeptic is only trying to show that DEF is possible. This is a total waste of time because it IS possible. Anything in a FANTASY is possible.
Dragons, unicorns, flying monkeys and pigs, suns and moons inside of planets, argon atmospheres, Aether, etc. are ALL possible in a FANTASY.
There are many computer games, books and movies with rivers and trees and stars and the Sun and Moon in them as well. They have S. Poles. They have star trails above the S. Pole. All these we accept as possible for a FANTASY.
If we are only to take DEF as a FANTASY - DONE! I don't think ANYONE will dispute it. IT IS POSSIBLE. You can have unicorns and dragons on the Hemidisks - whatever.
It is when anyone says that these are TRUE and represent the world we live in, that they are trying to move from Fantasy and Fiction to Hypothesis and Theory. These need falsifiable tests (hypothesis) and LOTS of evidence (theory). Until DEF produces any, it will ALWAYS remain a FANTASY.
