Human beings have always felt the need to know and predict events future, using Science. Many natural phenomena are explained by numerical models; but there are as many numerical models as there are phenomena; this is problem, a big problem; ideally, many events should be explained using for this, the least amount of mathematical models.Navier Stokes equations have been used for many years to simulate fluid dynamics. There are many particular cases in which these equations describe the dynamics of various phenomena as different as economics and meteorology. Most attempts to use these equations in a variety of fields, lie in properly defining the variables involved, giving them a physical explanation. This is an exciting challenge, of course ant that, is the main goal for this article: applying these equations, for explaining the Cosmos dynamic. If we look at many natural events, we will see that they evolve as a fluid: flocks of birds, vehicular or pedestrian traffic, are typical cases of analysis, but we can also observe this dynamic in events such as the stock market, the economy or even human relations.
