In the Cosmos, the nature and physical characteristic of chaos come from the own nature of the cosmic structuring.
Cosmos is structured by means of the union of infinitesimal energy points (space-time), which give infinitesimal points of matter later on. This matter has the property of being attracted mutually due to gravity, and for this reason, matter is structured in gravitational systems in such exponential order as: Matter points....., sub-atoms, atoms, stars, extra-stars and so forth.
So in the Universe, small units of matter join to form other bigger ones; these in turn join to form other bigger ones and so forth. Therefore the Cosmos structure is an exponential composition from smaller systems to bigger ones. Any physical element o system in the Cosmos doesn't exist, but as group of other smaller ones.
We could say therefore that any cosmic element is a system that in turn is composed by other sub-systems.
Because well, the properties, characteristics and behaviour of any cosmic element depends mainly on the behaviour of its components.
Mathematically, to any Cosmos element we can consider it as a variable that in turn depends of the other variables that compose it.
When in a certain cosmic space many cosmic elements exist and all they must subsist in this space, logically they must interrelate and interact jointly and to produce some common results if we observe them as a group or unique system.
Now then, when all the elements or sub-systems of this space interact among them, the results that take place depends on two types of factors, which are:
The influence that each element of the group suffers as consequence of its own component variables, and the influence that suffers because of its interaction with the neighbouring elements.
In this case we will say that the group or chaotic system is doubly influenced:
--First (underlying) coming from the variability and autonomy of its component sub-systems and
--Second (co-lateral) due to the interaction among these sub-systems.
Now then, in my opinion the initial point of departure in the chaotic adjustment is not of maximum importance because we should already know it. The important thing for me is the underlying variables of each element and the influence that the interaction with other elements can cause.
For us, the possible results of a chaotic situation it is of very difficult solution, because so much the variation of all the sub-systems that compose this chaotic situation as the way of interaction of these sub-systems are not within the reach of our knowledge.
Nevertheless, the question depends on the accuracy with which we want to obtain the results. If for us it is enough a mere approach, in this case we can obtain useful results for our necessities, and for it will be enough applying the knowledge of the variables that we know of each sub-system and later to value the possible interactions among sub-systems in a foregone and approximate way. In this case, the exactitude of the solution will also depend on the chaotic potential of each situation.
On the other hand, Cosmos has this question very easy because in chaos each element or sub-system has its own autonomy and it takes implicit its own physical laws for performance, so Cosmos alone has to wait results and later to marvel of the gotten creativity.
