Appears this 'skybubble' is above Sandbox, pretty high; like the roof of the map is VERY high. And the Grid is a physical floor for all the items, but for players; it dosen't exist and players as a result; fall to their death.
Anyway; heres the link to the Interview:

And heres a link to all the screenshots: including some of the Skybubble, and creations:
