One of the recurring numbers in this whole exploration of the underlying mathematics linking the Earth, Moon and Sun is 273, or 0.273.

This constant is reached through this simple sum: (4 - pi) / pi = 0.2732

The ratio of Earth diameter to moon diameter is 0.273

The ratio of moon diameter to Earth diameter is 3.66

27.32 earth days in Sidereal period of the moon ( one moon day ).

27.32 freezing point of water on Kelvin scale (K)

273 days in an average human pregnancy. (10 lunar months)

2,730,000 the circumference of the sun in miles.

-273.2 degrees celcius is the temperature of absolute zero.

Gasses expand by 1/273 of their volume with every degree on the Celcius/centigrade scale.

366 lunar days (27.32 earth days) = 10,000 earth days.

If you were to draw a circle inside a square, with the circle's diameter the same as the square's length, the area left over that the circle does not cover is 27.32% of the total area of the square.

And interestingly, John Cage's experimental music hit 4'33, where he released a song with 4 minutes and 33 seconds of silence and nothing else, is in fact, 273 seconds long.
