The ratio of Earth’s diameter to Moon’s diameter is 0.273. (The moon is 27.3 % the size of the Earth).

Comparing a square’s perimeter to a circle having an equal circumference, the circle’s diameter is 27.3% longer than the edge of the square. (easier to visualize in the illustration).

Inscribe a circle inside a square. The four corners make up 27.32% of the total area.

This is reached through the formula: (4 – pi) / pi = 0.2732

The relationship of the Great Pyramid’s height to half its base is 1.273:1 (or 4:π) and thus ‘squares the circle’.

-273.2 degrees Celsius is the temperature of Absolute Zero.

27.32 is the freezing point of water on Kelvin scale (K).

Absolute zero of water is 273.2% colder than the temperature it takes to boil.

273 days = average length of pregnancy (10 sidereal months).

27.3 days = human menstrual cycle.

27.32 earth days is the sidereal period of the moon (moon completes one full rotation, one ‘moonth’).

1/273.2 per C is the expansion/reduction of gas (Gasses expand by 1/273 of their volume with every degree on the Celsius/centigrade scale).

Sunspots revolve about the Sun’s surface in 27.3 days.

Water changes phase at 273°K.

273 days from the summer solstice to the vernal equinox.

2,730,000 is the circumference of the Sun in miles.

The triple point of water is defined to take place at 273.16 K.

The Cosmic Background Radiation is 2.73 K.

The Earth and Moon orbital periods are reciprocals. 1/27.32 = 0.0366 (366 days in a sidereal year) (1/366 =.002732) 27.32 days in one ‘moonth’.

273 m/s2 = acceleration of the Sun.

.273 cm/s2 = acceleration of the moon along its path around the Earth

Aside from that, I am really curious how the moon does relate to biological functions. Such as women's menstrational cycle, etc. Other sources have stated that without artificial light, the cycles would have originally sychronized with the moon. Has there been scientific research into how and why moon cycles would effect humans?
