A starburst of sound occurs within the border, forming the pentagram the five pointed star, five directions reaching their zenith and ultimate point of extension at the border of the circle meant to contain the explosion. Thus we have created a shape within the shape, with defined borders of its own. Everything within the new borders is well defined making the star, what’s within these more limited star shaped borders is universally more or less agreed upon and now fixed and defined. However everything outside the points and borders of the star taking up the rest of the space within the sphere is independent, not fully defined, and not fully under control of the star!

Ok. I just love looking into stuff. Obviously.
Some of you might find this interesting.
If not, I just add stuff for later reference for myself.
Lets see who Debussy is that the crater is named after.
Claude Debussy
WIKI
Claude-Achille Debussy (French pronunciation: [klod aʃil dəbysi])[1][2] (August 22, 1862 – March 25, 1918) was a French composer. Along with Maurice Ravel, he was one of the most prominent figures working within the field of impressionist music, though he himself intensely disliked the term when applied to his compositions.[3] Debussy is among the most important of all French composers, and a central figure in European music of the turn of the 20th century. He was made Chevalier of the Legion of Honour in 1903.
[4] His music is noted for its sensory component and for not often forming around one key or pitch.
Claude Debussy was born in Saint-Germain-en-Laye, France, August 22, 1862
Given that Debussy's music is apparently so concerned with mood and colour, one may be surprised to discover that, according to Howat, many of his greatest works appear to have been structured around mathematical models even while using an apparent classical structure such as sonata form. Howat suggests that some of Debussy's pieces can be divided into sections that reflect the golden ratio, frequently by using the numbers of the standard Fibonacci sequence.[26] Sometimes these divisions seem to follow the standard divisions of the overall structure. In other pieces they appear to mark out other significant features of the music. The 55 bar-long introduction to 'Dialogue du vent et la mer' in La mer, for example, breaks down into 5 sections of 21, 8, 8, 5 and 13 bars in length. The golden mean point of bar 34 in this structure is signalled by the introduction of the trombones, with the use of the main motif from all three movements used in the central section around that point.[26][page needed]
The only evidence that Howat introduces to support his claim appears in changes Debussy made between finished manuscripts and the printed edition, with the changes invariably creating a Golden Mean proportion where previously none existed. Perhaps the starkest example of this comes with La cathédrale engloutie. Published editions lack the instruction to play bars 7-12 and 22-83 at twice the speed of the remainder, exactly as Debussy himself did on a piano-roll recording. When analysed with this alteration, the piece follows Golden Section proportions. At the same time, Howat admits that in many of Debussy's works, he has been unable to find evidence of the Golden Section (notably in the late works) and that no extant manuscripts or sketches contain any evidence of calculations related to it.
To go a little deeper his and Maurice Ravel' (I love Bolero) field of Impressionist music.
The impressionist movement in music was a movement in European classical music, mainly in France, that began in the late nineteenth century and continued into the middle of the twentieth century.
While this era was characterized by a dramatic use of the major and minor scale system, Impressionist music tends to make more use of dissonance and more uncommon scales such as the whole tone scale.
Consonance and Dissonance
Physiological basis of dissonance Musical styles are similar to languages, in that certain physical, physiological, and neurological facts create bounds that greatly affect the development of all languages. Nevertheless, different cultures and traditions have incorporated the possibilities and limitations created by these physical and neurological facts into vastly different, living systems of human language. Neither the importance of the underlying facts nor the importance of the culture in assigning a particular meaning to the underlying facts should be understated. For instance, two notes played simultaneously but with slightly different frequencies produce a beating "wah-wah-wah" sound that is very audible. Musical styles such as traditional European classical music consider this effect to be objectionable ("out of tune") and go to great lengths to eliminate it. Other musical styles such as Indonesian gamelan consider this sound to be an attractive part of the musical timbre and go to equally great lengths to create instruments that have this slight "roughness" as a feature of their sound (Vassilakis, 2005).
In Western music, dissonance is the quality of sounds that seems "unstable" and has an aural "need" to "resolve" to a "stable" consonance. Both consonance and dissonance are words applied to harmony, chords, and intervals and, by extension, to melody, tonality, and even rhythm and metre. Although there are physical and neurological facts important to understanding the idea of dissonance, the precise definition of dissonance is culturally conditioned — definitions of and conventions of usage related to dissonance vary greatly among different musical styles, traditions, and cultures. Nevertheless, the basic ideas of dissonance, consonance, and resolution exist in some form in all musical traditions that have a concept of melody, harmony, or tonality.
Relaxation and tension have been used as analogy since the time of Aristotle till the present (Kliewer, p. 290).
In early Renaissance music, intervals such as the perfect fourth were considered dissonances that must be immediately resolved.

In human hearing, the varying effect of simple ratios may be perceived by one of these mechanisms:
Fusion or pattern matching: fundamentals may be perceived through pattern matching of the separately analyzed partials to a best-fit exact-harmonic template (Gerson & Goldstein, 1978) or the best-fit subharmonic (Terhardt, 1974), or harmonics may be perceptually fused into one entity, with dissonances being those intervals less likely to be mistaken for unisons, the imperfect intervals, because of the multiple estimates, at perfect intervals, of fundamentals, for one harmonic tone (Terhardt, 1974). By these definitions, inharmonic partials of otherwise harmonic spectra are usually processed separately (Hartmann et al., 1990), unless frequency or amplitude modulated coherently with the harmonic partials (McAdams, 1983). For some of these definitions, neural firing supplies the data for pattern matching; see directly below (e.g., Moore, 1989; pp. 183–187; Srulovicz & Goldstein, 1983).
Period length or neural-firing coincidence: with the length of periodic neural firing created by two or more waveforms, higher simple numbers creating longer periods or lesser coincidence of neural firing and thus dissonance (Patternson, 1986; Boomsliter & Creel, 1961; Meyer, 1898; Roederer, 1973, pp. 145-149). Purely harmonic tones cause neural firing exactly with the period or some multiple of the pure tone.
432Hz Anyone? I am no music theorist, but I have a hunch.
432Hz Validated
Turn your volume down for this one.
Any way that is one interesting crater.

I'm probably going to have to spend three days on this thread alone. This is awesome!
Some really amazing links and books listed in this thread.
I am thinking it's going to take more than a few days to explore them all.
Awsome contributions from everyone. Thanks my friend.
Hope you guy's find it as interesting as I did.
