This is part of one of our side tasks: to explain the Equestria with science. We actually ran a lot of CFD simulations to find the physical properties of Equestria world (The CFD stands for Computational Fluidic Dynamics). It is actually inspired by a post in the forums, we wish to digitalize the phenomenon in the show and derive a function to explain the Equestria.

This video is just a short illustration. It is not accurate and is not used in our calculation. 

The data from real simulations are still being processed.
