There are plans to walk again on the moon (above is a NASA visualization), but there is a sense in which the surface of the moon belongs to the surface of the earth, since the earth’s circumference is 4 times the mean diameter of the earth, *minus the moon’s circumference*.

The Earth and Moon were formed out of an early collision which left the two bodies in an unusual relationship to one another, in more ways than one. Here we discuss the diameter (and circumference) of each body as a sphere as being in the ratio **11** to **3.** The diameter of the Moon is 2160 miles so that the common unit is **720 **miles (the harmonic constantThis is the sacred number 720, which is large enough for all the regular numbers beneath it to form the octave 360:720 to offer all the intervals required to form five modal scales of Just Intonation. Key to understanding The Bible and Plato.) and the diameter of the spherical mean earth would be **7920 **miles.

The diameter of a circle has a circumference proportional to pior π: The constant ratio of a circle's circumference to its diameter, approximately equal to 3.14159, in ancient times approximated by rational approximations such as 22/7.. If one adds the two diameters, their combined perimeters will be 14 times pi, and using pi as **22/7The simplest accurate approximation to the π ratio, between a diameter and circumference of a circle, as used in the ancient and prehistoric periods.** leads to a combined circumference of **44 x 720** which equals **31680 **miles.

This is exactly the cosmological version of the equal perimeterA type of geometry where an rectilinear geometry has same perimeter as a circle, usually a square but also a 6 by 5 rectangle whose perimeter is 22, assuming pi is 22/7 or 3 + 1/7. geometry in which a diameter of 11 has an out-square of perimeter 44. The challenge is to create a circle of equal perimeter and adding 3 (the Moon) to 11 (the Earth) gives the diameter **14** which, times 22/7, equals **44**.

By adding half the moon diameter or 3/2 of it, either side of the 11 diameter, one comes to John Michell’s embellishment of the equal perimeter model in which the combined perimeter of the Earth and Moon is duplicated as 4 times the Earth diameter (a square) and a circle of radius 7, both being 44 units in length. The megalith builders appear to have understood both the geometry and its relationship to the earth and moon,

By scaling up this equal perimeter arrangement of the Earth as 11 and Moon as 3, by the harmonic constant (for Just intonationA musical tuning system improving the Pythagorean system of tuning by fifths (3/2), by introducing thirds (5/4 and 6/5) to obtain multiple scales. using modal scales), one not only arrives at a profoundly accurate model of the two bodies, in miles of 5280 feet, but one also finds a guiding basis for the design of the two bodies as a single composite body since, their ratio of 11 to 3 guaranteed that the two bodies would represent pi, in its simplest approximation of 22/7.
