The designs of the Egyptian pyramids are based on two models; the one with a square base, e.g., the Great Pyramid and the one with a rectangular base, e.g., the Red Pyramid. The surface angle of the latter model will not exceed 45 degrees; and the rectangular base will not equate the tilts of its four faces. The design of each of the two models follow a relativistic mathematical equation, similar to the equation of the so-called the Special Theory of Relativity of Albert Einstein. Some architects and commentators of these days have thought wrongly that the core essence of such pyramid is interpreted only in its geometric shape without studying the space-time factor in the pyramids design philosophy.
The above words may be seen as naive without showing the mathematical proof, but until you see that proof (in my recent paper), one should take in his consideration the unreadable but memorial side of the golden coin. The analytic and mental abilities of the human minds might not change from time to time; i.e., the Great Geometor has only one law for creation. The analytic and mental abilities of the researchers that were living on earth five millenniums ago is as the same as of those who are living today or of those who will live on earth five millenniums from now. The changes may be only in the accumulation of the outputs of the industrial researches. It seams the statutory-scientific-criteria of assessment that its current state of irreversibility in many historic realms has led some commentators to the domain of the dead hands, when they tried to devaluate the mental and the analytic abilities of those who previously searched on the master but harmonic laws of nature and conserved all their knowledge to those who will come after them.
