The reason that you use spherons is because spheres have only one dimension that is important. Supposing that you need two more dimensions is simply a notion of spacetime and is not necessary for primitive action of aether matter.
Just matter and action are all that is necessary for time and space to emerge as long as there is a phase relationship between matter and action.
Thermo has to do with all of the forces of particles including gravity. Gravity compression, densification, and adiabatic heating of matter are the founding principles of the thermo of stars and planets.
I am sorry that I make you crazy, but black holes do exist...but are really more like boson stars. The quantum gravity of biphotons works just fine in the boson stars that mainstream science calls black holes. There is no information lost in the phase transition from fermion matter accretion to the action matter of a boson star.
Dark matter and dark energy for that matter are both simply manifestations of the exchange properties of quantum gravity. Quantum exchange at the microscopic scale is very well known but since until now, there has not been quantum exchange at the galaxy or larger scale.
Quantum gravity results in an exchange interaction among stars due to their mass loss rates. That exchange coupling between inner and outer galaxy stars is what keeps galaxies rotation constant, not dark matter. Angular momentum is simply exchanged from inner to outer star, inner stars then slow and outer stars speed up. There is no such thing as dark matter.
The same for dark energy. The universe seems to accelerate despite mass density decreasing by careful measurement of supernovas of distant galaxies. This is the argument for dark energy. But aethertime has a very different cosmology that fits the universe the way that it is without any new dimensions or constants. So, no dark energy either.
You presume a universal and central black hole and it is true that there is a universal and central surface; it is called the CMB. Everywhere in the universe the CMB provides a reference surface and for aethertime, the CMB persists for all time. There are no event horizons except that of the edge of the universe just beyond the CMB.
