I think firmament above and space can only go that far vertically... Horizontally however I could assume if I hopped in a ship and head south I can discover more space. I will post The Q map right now, if you look at the top left corner you'll see Atlantis Lemuria and Mu. All considered lost or sunken continents... I just can't accept that.. I think It's more likely that they are beyond Antarctica and god only knows what else... I also think the south China sea is very important and might offer access to more space by heading south.. Use the air age map when considering this perspective.
