The Great Pyramid and the Axis of the Earth  Part 2 (cont.)
By Gary Osborn and Scott Creighton
So in effect, these two angles of 11.75º that intersect the centre of the Queen's Chamber, add up to 23.5º  the same value as the angle intersecting the King's Chamber from the south vertice.
2 x 23.5º = 47º is meaningful and within context here, because 47º is the radius of the precessional circle traced in the sky over c. 25,920 years by the Earth's tilted axis.
Staying with the theme of Precession which is also associated with the obliquity of the Earth's axis, the angles of the sloping sides of the GP are 51.84º, and using the Platonic value for precession, the value 51,840 amounts to two precessional cycles of 25,920 years.
If this isn't a coincidence then we would have to ask why two precessional cycles? If intentional then perhaps this detail is part of the code we are unravelling here and something we have yet to decipher.
What if we now add the values of these four angles together?
11.75º + 11.75º + 23.5º + 6.5º = 53.5º
As said, as the Earth turns daily on its axis of 23.5º, the GP comes as close as 6.5º and as distant as 53.5º from the Ecliptic Plane (see Fig.1).
Again, what are the odds against this, if what we see here doesn't reflect any intent on behalf of the pyramid's architects?
But this is not all . . .
The next logical step would be to examine the angle between the two chambers. One would suspect that the angle would also be 23.5º and perpendicular with the 23.5º angle that intersects the King's Chamber.
At first, one is disappointed to find that the chambers are centred on an angle of precisely 26.77º  not 23.5º.
However, it's interesting that a line from the centre of the KC to the floor of the QC, intersecting the point where the floor and the central axis of the GP meet, is indeed 23.5º: and the thing that is so appealing about this alignment, is that the floor of the Queen's Chamber is level with the 23.5th Course Layer of the GP.
As many will know the core masonry of the Great Pyramid is now exposed due to its outer limestone casing having been removed centuries ago. The core masonry now consists of 203 steps or layers from the base to the truncated top of the pyramid.
So in effect, this 23.5º angle from the centre of the King's Chamber intersects a point (the centre of the green cross in Fig. 8) that is already markedup to the value of 23.5.

It appears that the same number of Course Layers from the base of the GP to the floor of the Queen's Chamber was used by the architects to verify this angle and its alignment.
One could argue with this and ask why go to all this trouble? Why not centre the two chambers on an angle of 23.5 degrees if this was the original intention?
The simple answer is that for the architects this was impossible given the 51.84º angle of the sides, which appear to have been vital to the overall design.
If the architects had already determined the positions of both chambers via the 23.5º and 6.5º angles to the centre of the KC, and the two 11.75º angles that are half the 23.5º value for the QC, then it would have been impossible aligning the centres of both these chambers on a perpendicular 23.5º angle. The only way this would be possible was if the angles of the sides were 48.42º  a difference of 3.5º. This means that the side angles of 51.84º was of paramount importance.
The geophysicalassociated message has already been made clear with the angles we have already discovered, and as we will see later, this perpendicular angle, although important, would have been considered secondary in the overall plan.
So to perhaps show that this alignment would have been ideal in practice and was originally intended for reasons which will soon be made clear, the next best thing was to make sure that the intersection point of both the centreline of the GP and the floor of the QC were connected to the centre of the KC by an angle of 23.5º, and that as an afterthought it was decided that the number of Course Layers from the base to the floor of the QC would both reflect and confirm the value of this intended angle.
This could be argued of course, but this is our explanation as to how the architects may have got around the problem of not being able to centre both chambers on a 23.5degree angle in addition to the other alignments they had already made and on which the overall geometry of the GP depended.
