Recently, worldwide medias reported following headline news: “on March 30, 2007, Dassault Systems, one of the first world editors of 3D computer solutions, and architect Jean-Pierre Houdin, reveal the first theory devoted to the construction of the pyramid of Cheops that is scientifically validated, during a news conference presented at the Géode, City of Sciences, Paris ”.
One reads here clearly that 3D computer simulation has scientifically validated this theory of pyramid construction. The system introduces the use of internal ramps, instead of the external ramps previously suggested by Egyptologists. It is common knowledge that a computer works with the data that have been provided on its hard disk. If these data prove to be false or inaccurate, then the computer program will simulate and confirm a false theory. According to Dassault Systèmes, it is the first time that 3D simulation is employed in the demonstration of a theory on pyramids construction. This is wrong. Recently, the Palais de la Découverte, Paris, organized an exhibition dedicated to the Hypothesis on pyramids construction (December 19, 2006 to March 13, 2007, see the monthly magazine Découverte Revue du Palais de la Découverte, December 2006). Three theories were presented there, two bearing on a system of ramps and hewn stones, and my own one (agglomerated limestone concrete, by chemistry, instead of carved stones). These two other theories were based on “a demonstration confirmed by 3D simulation”. Although less sophisticated than the program used by Dassault, they worked on the same guiding principles. The first one, by J.P. Petit, former Research Director at CNRS, recommended an external ramp. The second one, by P. Crozat, architect doctor-engineer, favored an accretion system, external ramps and machines.
