The Great Pyramid

Calculations by this writer reveal a number of potentially significant astronomical alignments for the great pyramids during the precessional cycle that began 86,960 years ago (the third prior to the present one). However, in view of all the uncertainties involved, the scenario set out below is only tentative.* There appears to have been a master plan from the very beginning, because in the case of pyramids that seem to have been built in several stages, the features that indicate the completion dates belong to an earlier phase of construction.

*Stellar coordinates were first corrected for transverse and radial proper motion and then precessed on the basis of a precessional rate of 50" per year and a change in the axial inclination of 4 degrees every 25,920 years. The main uncertainties are the exact angle of the various passages and shafts, the variation in the rate of precession and change in the axis over time, exact data for stellar proper motion, distance, and radial velocity today, and the variation in proper motion and radial velocity over time. All the alignments mentioned in the text are accurate to within one degree.
The great pyramids include the two huge pyramids at Dahshur, 17 miles south of Giza, which are usually attributed to Khufu's father Sneferu ('Sen-nefer' means 'the two energies'). Just as the position of the three Giza pyramids reflects that of the three stars of Orion's Belt, so the Bent (southern) and Red (northern) Pyramids of Dahshur correspond to Aldebaran and Epsilon Tauri respectively, with the Nile representing the Milky Way. The Bent Pyramid is so called because its lower part has a steeper slope than its upper part. This symbolizes duality, as do the two entrances (one of them in the western face), which lead to two separate sets of chambers.[11] Furthermore, both entrance passages change their angle of descent part-way. The lower part of the pyramid may have been built 86,500 years ago, when the vernal (spring) equinox passed from Cancer into Gemini (the Twins), and the lower part of the northern descending passage was aligned with Nekkar, the then polestar, in the constellation Bootes.
