"A little consideration reveals that, should the terrestrial axis be turned tomorrow into a new astronomical direction by any angle of inclination toward the ecliptic, the Great Pyramid would remain properly oriented to the north and south poles; there would be a new celestial pole and, if so positioned, a new polar star, but the pyramid would remain with two of its sides aligned with the geographical poles.
Should the terrestrial axis be turned by anything like 180°, north and south would change places (a hieroglyphic text quoted in Worlds in Collision, p. 107: "The south becomes north, and the Earth turns over"), but the pyramid would not be disoriented. Actually, quite a number of authors of classical antiquity refer to earlier changes in the inclination of. the terrestrial axis and to subsequent positions it took.
Only with the additional displacement of the geographical position of the axis (location of the poles), would the pyramid be disoriented (unless the poles should travel along the meridian of Gizeh). The present azimuth (orientation) of the sides of the Great Pyramid indicates that any disturbance in the geographical position of the poles since it was built must have been of a temporary character, the Earth's equatorial bulge acting as a stabilizer. In such a case wobbling would result - a residue of such wobbling is still present."[1]
