The GP Entrance axis thread is getting pretty big so I decided to open a new one.

From the PTs it is known that the imperishable stars of the North were very important for AEs. The entrance of all three Giza pyramids was on the North. While the King and Queen shafts of the GP have been related through the astronomic notion of “transit” to stars like Sirius, Kochab, etc, the same thing cannot be done with the entrance - descending passage. This angle according to Petrie is 26.531 degrees. When the pyramids were built, in the north the star with the smallest altitude at transit was Thuban which was closest to the celestial pole, this angle was about 31.4 degrees. Thus it’s impossible to have an imperishable star as seen from ancient Giza with a 26.531 degrees altitude at transit. Could this mean that if a star is targeted it is not targeted at transit but rather at an important time/date? If this is so then how can we be sure that this also doesn’t hold for the shaft angles also?

Clive made an important find when noticing the Earth to Mars orbit period ratio encoded in the horizontal offset of the GP entrance. Let’s thus stick with Mars, but we need a date. I will take the date when Earth perfectly aligned with Uranus, Neptune and the center of the Milky Way. This date agrees perfectly with Kate Spence’s dating based her Kochab/Mizar calculations. This is March 27 2466 BC. Starry Night Pro Plus is used and the coordinate is that of the sphinx.

What we notice is that at Mars transit the altitude of the star Alioth is 26.496 degrees – the exact angle of the descending passageway of the GP which points North.. Alioth or Epsilon Ursae Majoris is the brightest imperishable star with an apparent magnitude of 1.75. But at Mars transit the azimuth of Alioth is 13.7057 degrees. This relates to the fine structure constant a (1/a = 137.03599911).

Since the horizontal offset of the GP based on the center of the pyramid is 4.0933 degrees, and it is this offset that as Clive has shown encodes Mars data let’s set the time (date is the same) so that the azimuth of Alioth is exactly this angle (4.0933 degrees) – this is to the East. Well it turns out that at this time the latitude of Mars is 26.655 degrees! The same exact angle of the descending passageway that starts with this same entrance that encodes the orbit ratio of Mars to Earth. Off course if we go one day back or forth the error for this double encoding increases – in other words it is this exact date that we computed via the earth – Uranus – Neptune – Milky Way alignment when the error is the least (0.159 degrees). In other words we have a perfect match. Let’s also note that the angular separation between Mars and Alioth was close to a right angle: 89d 48’.
