Precession of the Equinoxes
This is a small simple to use app designed to show how the earth's wobble effects the position of the equator and the earth's poles, thus completly changing the weather patterns and the locations of glaciers and deserts over a long period of time.
Everyone knows the earth spins, that is how we get day and night, but also the earth is tilted on it's axis at 21.5 degrees and while it spins this tilt also spins, like a top winding down, but very slowly. It takes about 25,800 years for it to spin 1 time, It was discovered long ago and is directly related to the zodiac, they noticed that on the winter solstice every 2150 years that the sun rose in a different constalation, the last one occured at year 0 when we entered the constalation of Pisces and we will enter the next one, Aquarius, in the year 2150. notice that it seems backwards? well it is, and thats why it's called the Presession of the Equinoxes.
