Moon Gravitational Model GRGM1200A :    • Moon Gravitational Model GRGM1200A  

The earth is an object in space, it's not flat, and it's also not a perfect sphere, especially in terms of gravity. But it is subject to the laws of physics, and since there is much debate about the earths geometric shape, global warming and why the weather is getting increasingly more extreme, without taking any sides, I provide an explanation that the earth is subject to the laws that can be seen in all spinning objects in space and explained using the Dzhanibekov effect, also known as the tennis racquet effect.

One important note in this simulation, is that the EGM96 is a snapshot in time. The distribution of the earths gravity changes constantly with tectonic movement, subterranean flows, freezing/thawing of the poles throughout the seasons. So until I can process data of earths gravity distribution over certain time frames, this simulation is really only applicable if the earth became a solid body who's gravity distribution remained constant from the time the EGM96 was created.
