Beauty is sometimes described as being in the eye of the beholder and also as only being skin deep. Hence it has no actual link or need for truth. It would be nice for a theory to be pleasing, to be beautiful but there is no valid reason for this to be so. Our concepts of beauty are both personal and cultural and may rely on conciseness and symmetry and evenness [flawless] but most of us know there is more beauty in a handmade, flawed piece of pottery done by someone we love than in a Venus de Milo or Winged Victory of Samothrace, though admittedly they are beautiful to me.
So science and scientific theory do not have to be beautiful, they just have to work, concise or complex, no need to care, just to appreciate.
On the theory of the discs in general, appropriating it to theory suggesting that turbulence could act to promote, rather than inhibit, this planet formation process.
If appropriate for discs in other contexts it does not imply that it must work in all disc settings or subsets but it is still of interest as to why when a lot of the basic physics is very similar.
Gets back to the gravity interactions of that mass of stellar dust thrown together in that cluster. Larger or smaller sizes presumably of different density and thermal activity materials [stars and planets] might behave differently in accumulating mass.
