Greetings several -- especially Robert B Interesting concept. Haven't had time to read much as I'm pre-occupied at the moment with another matter. I did do the usual Googling thing however, and didn't find too much support for this hypothesis, especially seeing that it is more than 20 years since it was floated. This site -- http://doernenburg.alien.de/alternativ/pyramide/pyr17_e.php -- gives a reasonable criticism I think. Of particular interest are the photos of typical core characteristics of pyramids of the era in question. You'll note that the tenth of a millimetre accuracy is not shown and the blocks are essentially of different shapes -- not cast from the same mould obviously. If you are interested in excellent masonry (including large blocks) have a look at these two addresses -- http://www.brynmawr.edu/Acads/Cities/wld/03080/03080m.html http://www.brynmawr.edu/Acads/Cities/wld/03090/03090m.html This is *real* accuracy. I believe these joints are water-tight, they are dry ie without mortar, and the stones are granite, -- not capable of being created by any "slurry casting" methods. Some of these are also *very* large. This is just another one of those mysteries -- we don't know how they did it, but this does not nean that God did it or aliens did it or it was done with magic or psychic powers. I suggest the Egyptian phenomenon is of similar kind. I do marvel at your credulity. You seem always to be poised like a compressed spring waiting to pounce on MS (not the charity I support [Chuckle]) on the most sparse and flimsiest of evidence. Has no one ever remarked upon this to you? Man is intelligent and ingenious. Given sufficient motivation, he can achieve amazing feats, at which I marvel, even with quite primitive technology. This ingenuity and intelligence eventually produces a sophisticated technology. I do wish you could join me on this mountain top.
