I actually have a book about this - it's hilarious! Didn't buy it of course, found it helping a friend clean out a garage prior to moving. People will believe just about anything.
i guess thats why many prominent astrologers have put this theory forth for centuries....no, this is not generally taught in the lower grades.
In 1692. I wonder what scientific evidence he based it on. http://en.wikipedia.org/wiki/Hollow_Earth P.S. I don't think he was an "astrologer," although I have no doubt he was a Scorpio.
the dalai lama is a believer in the hollow earth theory, there are several astrologers today who discuss this as relevant in professional circles. Halley was an astronomer, and remains respected. Fibonnaci came out with his numbers in the 1400's ....they are no less relevant today.
I didn't know that the Dalai Lama was a scientist and I didn't think that astrologers' opinions had anything other than entertainment value.
