When I was in High School, nearly fifteen years ago, I wrote a paper about Ancient Egypt. In doing research for it, I came across a magazine which featured the story of how some scholar had analysed the stone blocks of the pyramids, and come to the conclusion that they had been poured and not hewn. The evidence for this included some hair or fiber that had been found within one of the blocks when it was split open. I don't remember the name of the scientist or even the magazine, but perhaps it was this Davidovitz who has been working on this theory for quite a number of years now...
