We just established a set of noteworthy relations between biological beings; a classification and a curve of masses by level. Do they specifically apply to the world of beings or can they be found elsewhere ?
While examining heavenly bodies, we can bring to light the same classification between individuals and assemblies :
A star system is made from a few different assemblies: one or two stars and some planets.
A galaxy joins together one hundred billions of similar stars or more.
- are formed by several different galaxies; our local group contains about twenty of them.
Groups of galaxies
- associate galaxies in their thousands.
Clusters of galaxies
- muster a few clusters of galaxies, 5 on an average (fig. 3.1).
Figure 3.1 - On the left, local supercluster where we can see clearly clusters (Martha P.Haynes).
That simple list allows to divide heavenly bodies into two categories, only based on structural considerations.
Those formed by a few often-different constituents, stars systems, galaxies groups, super clusters of galaxies; we can define them as individuals according to our classification.
Those constituted by a great number of similar components, stars and planets, galaxies, clusters of galaxies. They meet the definition of assemblies.
As we have just done for biological beings, we can now present this classification by levels :
Figure 3.2 - Heavenly bodies classification
So, according to the work previously achieved, we come across a structure where we find again all the known objects of matter, living beings and cosmos; we can call this structure universal.
