Hello dear Eckard,
It's very interesting.
The photons, if my memmory is good, can have a number of photons of all frequencies but c restc constant and the total system no .
The pression and the volumes still are essentials and foundamentals .
The total energy and the total number can be seen , constant or not.
It 's very relevant when an atom absorbs and re emits the frequences or not ??? hihihi The kinetic energy seems in the rationality.
The pauli principle, if I remenber, does not hold for photons.
It's there it's still interesting with spheres and sphericals fields and coordonates.
If the rotation is inserted ,it's very relevant too about the momentum.
A BEC can be applied of course , the sphericalization of referentials facilitates many things .
I have seen a beautiful method of Lagrance multipliers where we see the equilibriums and the entropy of the system .
The Planck radiation equation is interesting evidently.
I consider the system of photons like the gravitational system for the number, of course the rotations imply the specificity.
An important thing I beleive is what the gravity do not change its number, and the light can be fractalisable .The gravity is only in the mind for the understanding of the fractalisation.It's interesting in my humble opinion because we can fractalize really the light and thus we shall find the different volumes of the quantum uniqueness.We can see the synchro or the effetcs of the gravity on the system for an evolutive point of vue.
The thermodynamical parameters of course permits to see the different steps.
But for results, it's necessary to have a system of real fractalisationn and too the captors of evolution in gravity systems.
The spherical superimposings are thus in a dance of frequencies, rotations, and informations thus, there the volume is esential .
I have a big unknown which makes me crazzy with a stirling approximation and some substitutions, but I have problems for the distribution of fractalisation because I superimpose the gravity and the quantic finite number .And of course 1 rests like it is and the others no, but the difficulty is for the synchro of rotating volumes of spheres implying mass, a parameter of evolution is necessary , if not all is difficult , like a limit.
But if the correct fractal of a volume of sphere is made, it's possible .
But Of course we don't know the ultim code in the gravity studied.
A possiblity is to insert a system well studied which polarises and has its frequences of evolution , thus we can extrapolate the correct serie, but of course we don't know how will be the fractalization of the light.
It's a real puzzle, but I will arrive ....I hope .This number makes me crazzy.
Very best Regards
Steve
