Interesting additions! Thanks for the effort. :tup:

I strive to be openminded as much as possible, but in this instance, I have to say that I have read a bit about the inverted earth theory and even I can't give it much probability at all. hmm

Ditto on the part of the theory about the Nazis escaping to the land beyond the South Pole. blah

Mind you I am enjoying hearing all theories though! grin
