ST In BG, I was very curious about the large art object in the Vatican(I don't have a link, yet). It looks like earth with a chunk missing and inside a layer of earth looks like an iron grid encasing the earth and within it's hollow. I believe the art is a replica of our earth. Is that true?

Also, are there E.T. species called the Binx, Yoorach, and Lu'Pan to name a few. I was reading the babbling of a guy claiming to be a time traveler. Thank you.
