The average temperature of Egypt equals the average temperature of earth = avg. temperature of Queen's Chamber = 68 degrees Fahrenheit. With the original surrounding courtyards and temples in place, the pyramid was used as a sundial.
The Great Pyramid is the most accurately aligned structure in existence and faces true north with only 3/60th of a degree of error. The position of the North Pole moves over time and the pyramid was probably exactly aligned at one time.
The Great Pyramid is located at the center of the land mass of the earth. The east/west parallel that crosses the most land and the north/south meridian that crosses the most land intersect in two places on the earth, one in the ocean and the other at the Great Pyramid.
The curvature designed into the faces of the pyramid exactly matches the radius of the earth.
The average height of land above sea level for the earth is 5449 inches. This is also the height of the pyramid.
North Star Pointer:
The Descending Passage pointed to the pole star Alpha Draconis, circa 2170-2144 B.C. This was the North Star at that point in time. No other star has aligned with the passage since then.
The 344 ft. length of the Descending Passage provides an angle of view of only +/- 1/3 of a degree. Alpha Draconis has not been in alignment for thousands of years. The next alignment will be with the North Star, Polaris, in about 2004 A.D.
Polaris in Greek means Satan.
