Pyramids Built from the Inside-Out?

French architect Jean-Pierre Houdin suggested a controversial theory on how ancient Egyptians built the pyramids: from the inside-out!

Last month, however, in an announcement that has divided the academic community, French architect Jean-Pierre Houdin revealed a compelling new hypothesis that the Great Pyramid was built from the inside out. In an unusual departure from the archaeological techniques usually deployed by Egyptologists, he arrived at his theory with the help of engineering software typically used to design cars and aircraft.

Houdin believes that a smaller, long, straight ramp consisting of two carriageways was used to build up to the 43m mark of the pyramid (about 73 per cent of its volume). Then the frontal ramp was systematically dismantled and the blocks that formed it used to complete the upper part of the pyramid through a ramp that spirals around the inside of the structure. According to Houdin’s calculations, the volume of rock used in the external ramp would have been exactly the volume of rock required to construct the pyramid above the 43m mark.
