There are some fascinating things about our Solar System that leave the fingerprint of Intelligent Design. One of them is the size relationship between the Earth's diameter and that of the moon.

If the moon were 11 units wide, the moon would be almost exactly 3. First, let's look at the diameters of the Earth and Moon:

Earth: 7917.5 miles in diameter
Moon:  2159.2 miles in diameter
       ------------
       7917.5 / 11               = 719.772727272...
       x 3                       = 2159.31818181...
       2159.2 / 2159.31818181... = 0.99994527 = ~99.9945% accurate

So the “perfect numbers” would be 7920 miles for Earth and 2160 miles for the moon. The degree of accuracy is astoundingly high! Much more than we should ever expect from a universe origin explosion (Big Bang) and random cosmic collisions. Our Earth and its only satellite have a strange and unexpected size relationship.

Earth:           7917.5 miles
"Perfect Earth": 7920 miles (3960 mile radius)
                 ------------
                 0.99968434343... = ~99.9684% of "Perfect" number

Moon:            2159.2 miles
"Perfect Moon":  2160 miles (1080 mile radius)
                 ------------
                 0.9996296296296... = ~99.963% of "Perfect" number

Isn't that incredible? So back to the “11 units wide”, the 11:3 Earth:Moon ratio. Let me restate it another way. If we had a primitive digital display that was only 11x11 pixels, and we used it to show a representation of the Earth:

Adding a 3x3 pixel moon has an almost perfectly defined diameter, even on the super low resolution 11x11 screen. Why should this be the case?

Further interesting aspects of the numbers

Both “perfect numbers” have digital roots of 9 (7+9+2+0 = 18 = 1+8 = 9, 2+1+6+0 = 9) because all multiples of 9 have digital roots of 9. 7920 / 9 = 880 and 2160 / 9 = 240. Curiously, 2160 is also 6³x10.

While the mile is of course, arbitrary, the relationship between the Earth and Moon is not, and we could show that just the same in metric.

I was also surprised to find that the closest whole numbers of the “perfect numbers” converted to Roman miles (1 mile = 1.08753862 Roman miles) are also multiples of 9:

7920 miles = 8613.31 Roman miles, 8613 / 9 = 957
2160 miles = 2349.08 Roman miles, 2349 / 9 = 261

But the big takeaway should really be: why the mathematical relationship between Earth and Luna? We don't see it in the other planets and their satellites, nor do we expect to. It's just another one of those things that's worth pondering for a little while. Where was Space.com with this fascinating little bit of information? Oh yeah, most of that world would rather you believe we live in a universe constructed by random happenstance.
