The Great Pyramid and the Axis of the Earth - Part 2 (cont.)
By Gary Osborn and Scott Creighton

Appendix:

Precise Angles

It's highly possible that the builders of the Great Pyramid were never as precise or as accurate as many of us would prefer to be or are capable of being today.

We like to be precise and it's only natural that we would prefer to know the exact values of these angles down to the nth degree; however, we are also aware that in being too precise, one can miss the point entirely.

Were the architects, or for that matter, the builders of the GP as precise as we are today? Were they concerned with fractions of a degree? Perhaps up to a certain point yes; but in being too precise we really don't want to overstep the whole thing and lose the simplicity of the meaning which we feel we were meant to comprehend here.

The following angle values based on Petrie's measurements of the Great Pyramid of Giza were calculated and kindly passed onto us by Spiros Boutsikos.

In his own words:

"Using Petrie's measures - that is mean height of KC, base height from ground level we compute that the middle of KC's height from ground level is:

[(1923.7"+1921.6")/2 + 1692.8"]/2 = 87.7005 rc

Now taking into account the exact width of KC and its distance from centre we compute the horizontal distance from the corner using the half base length:

115.182 m - 330.9" - (5.24 m/2) = 198.9414 rc

Thus the angle y is:

y = tan^1(87.7005/198.9414) = 23.7896 degrees

The KC center-GP apex angle based on Petrie measures is 6.242 degrees.

Now computing the mean height of Queen's chamber is tricky. We need to compute the cross section area and then equate it to a parallelogram with a width equal to the width of the same chamber. This is the volumetric center of the chamber (notice the top part is a triangle):

[184.47"+ (245.1"-184.47")/2]/2 + 834.4" = 45.6904 rc

Thus the angle t is:

t = tan^1(45.6904/220) = 11.7326 degrees.

2 x 11.7326 degrees = 23.4652 degrees."

Throughout the main text we have expressed the angle values of 23.5º . . . 6.5 º . . . and 30º.

These values are directly related to the recognised and established geophysical knowledge we have of the Earth today - i.e., the obliquity of its axis - and the location of the Great Pyramid which has a direct orientation relationship to this obliquity. Therefore these particular values are our 'touchstone' - our criterion. After all, it's through these angles and their values that one immediately recognises a geophysical connection here.

We are well aware that in using these particular values we also encounter a problem . . .

According to the Milankovitch theory, which has largely been accepted, the tilted axis slowly shifts between 22.1º and 24.5º and back again over a period of 41,000 years. It is said that the angle of the axis is now decreasing and at a rate of 1.19 metres per century.

Egyptologists say the Great Pyramid was constructed during the 4th Dynasty period, between 2,500 and 2,400 BC. The obliquity of the axis at this time has been calculated to have been around 23.96º - almost 24 degrees.

In arc hours and minutes this figure is 23º 58'.

Again, at present the exact figure for the obliquity (incline) of the axis is 23.44º and in arc hours and minutes it is 23º 26'. However, as mentioned, the obliquity angle of 23.5º is popularly used as a general figure and so for many it's one that is instantly recognised.

We have to set tolerances, and given the enormous size of the pyramid, if the true value of the angles from each of the three points to the chambers are within less than half a degree of the geophysical angles that relate to us today as well as the angles relating to the era of the 4th dynasty, then we know that there is indeed something to all of this, and this is indeed what we find.
