The Great Pyramid and the Axis of the Earth  Part 2 (cont.)
By Gary Osborn and Scott Creighton
Again 23.96º is still within half a degree of 23.5º, the recognised figure we use today. Of course if the obliquity of the axis at the time the Great Pyramid was constructed was almost 24 degrees, then ideally this would be the figure we should be aiming for and we are well aware of this.
However, as we will see, we find that the precise angles given to us by Spiros (based on the more reliable measurements of the Great Pyramid to date) fall well within a third of a degree either way  i.e., within a third of a degree of the geophysical angles that relate to us today and amazingly within a quarter of a degree of the angles relating to the era of the 4^{th} dynasty when the Great Pyramid was built so say the Egyptologists.
Let's now examine the angle values passed onto us by Spiros Boutsikos and for clarity we will round off the fractions of these values to two decimal places.
1. The South Vertice to centre of King's Chamber is 23.78º.
This value is within the correlative margin of 23.5º to 24º  well within half a degree. In fact the difference is only 0.28º  within a third of a degree.
If on the other hand the architects were trying to work to an angle close to 24º  i.e., 23.98º then the difference between 23.98º and 23.78º shows a discrepancy of only 0.20º  one fifth of a degree.
Mean difference between the two: 0.48º  again, less than half a degree.
2. The GP Apex to King's Chamber centre is 6.24º.
Again, this value is within the correlative margin of 6º to 6.5º  again within half a degree. In fact the difference is only 0.26º  within one third of a degree and closer to a quarter of a degree.
For us, the 30ºN latitude of the GP, gives the above two values their meaning and the reason why they are there within the geometry of the GP.
So, 30º subtract 23.78º = 6.22º.
Spiros' value is 6.24º  a discrepancy of only 0.02º  which is less than the 3 arcminute discrepancy of the GP's alignment to the four points of the compass. So again these two angles are in exact correlation with the geophysical picture of the tilted Earth and both in relation to the GP's location.
Let's now work to the condition of the Earth and the GP's location during the time of the 4^{th} Dynasty.
30º subtract 23.98º = 6.02º.
Again, compared to Spiros' value of 6.24º this gives a discrepancy of 0.22º  within one quarter of a degree.
3. According to Spiros' calculations the North Vertice to centre of Queen's Chamber is not 11.75º but 11.73º  but again, this is only a discrepancy of 0.02º
2 x 11.73º = 23.46º  almost spot on 23.5º  a difference of 0.04º
What about the obliquity value for the axis during the 4^{th} Dynasty?
23.98º divided by 2 = 11.99º.
11.99º subtract 11.73º = 0.26º  again, a quarter of a degree difference.
Altogether the difference between the precise angle values, 23.78º and 6.24º as calculated by Spiros, using Petrie's measurements of the Great Pyramid, and the geophysical values that relate to us today, 23.5º and 6.5º, is within 0.28º  not within half a degree, but well within one third of a degree.
Working the other way, the difference between the precise angle values within the GP and the angles that relate to the era of the 4^{th} Dynasty, 23.98º and 6.02º is within 0.22º  within a quarter of a degree.
So the angles we have found within the geometry of the GP can work either way:
A). The correlating values of the angles found within the GP match by one third of a degree, the geophysical condition of the Earth as we know it today as referenced by the GP's location on the earth, and after all, it is through this geophysical data that we recognise and identify the connection here.
B). The correlating values of these angles are also within a quarter of a degree of the geophysical condition of the Earth as referenced by the GP's location on the earth, at the time of the 4^{th} Dynasty when the GP was constructed.
And what if we add together the precise values passed onto us by Spiros to find the second of the GP's two distances from the Ecliptic Plane?
