Apparently something new has been added. On another board we were hit by a drive-by advertiser who's done a film on this. The sad thing is that it's an excellent bit of cinematography. But they're working from Osmanagic's "facts" (it's now claimed that NASA made the initial find and that they were interested in it because the hills retained heat longer than normal and they therefore concluded they were hollow.)
If you want a link, U2U me and I'll give it to you. But I don't feel like advertising it elsewhere.
I exercised my Moderator Powers (with the secret decoder ring) and trashed it on the other forum, since we have a "no advertising" rule and this was clearly advertising.
(sigh) The Forces Of Science need a better press kit.
