forbidden archeology: suppressed new evidence , pyramids made out of concrete ? # www.youtube.com 34 




the pyramids in egypt were built in a surprising way: they used a chemical formula to prepare a concrete limestone with which shaped the million stone blocks used in its construction. they are man-made stone. so they not had to cut them in distant quarries and then bring them back without wheels and pulleys by the desert sands. nor winched blocks weighing between 4 and 70 tons to the height of a 40-story building, then you assemble each other with such precision that does not fit the card from a deck in 5 of their faces; even impossible to achieve with current technology. tags
