The fractal nature in hyperbolic geometry terms of the big bang

The first model is based on the idea that
tilings in an hyperbolic space behave like Gamma 1 modular groups
as triangulations ( polygonal tilings in hyperbolic spaces):

This model is based on an Escher like Gamma modular form
hyperbolic tiling of E_11 as an extended Platonic solid.
The model is a fractal scaling one in which the vertex number
of the hyperbolic polygons are used to both radially scale
and number the particles that time a limited quantum mass state.
It is a lattice in 2d space that can be mapped to a 3d manifold.
4, 6, 8, 12,20 are the vertex numbers of the platonic solids:
my v[n] function is a generalization of that.
I use a radius ratio function of powers of vertex minus one time Pi.
The quantum radius is taken as:
r=2*Pi*hbar/(m*c)
The temperature is the measured background temperature:
and the Hawking entropy formula is used to determine a black hole
radiator mass
at that temperature.
The number of particles in the model are the count of
hyperbolic tiles at different levels of the fractal scaling.
The finding is that the level n=8 accounts for an E_11
model hyperbolic big bang with the temperature
that is observed.
The level n=8 particle number is;
1239964645920142118597441
or about 10^24
and the particle mass at that level is;
1.083432147883765*10^12/1239964645920142118597441=8.737605152280621*10^-13
gm
which is less than the classical 10^(-5) Planck mass.

The second model uses a Tetrahedron as the basic figure:

This model using a four vertex hyperbolic uses
50 levels instead of 8...
(Nature usually shows 7 levels above one.).
Gauge mass is about the same
at
7.545864220675408`*^-13 gm
but there is a 3/2
factor necessary to get the quantum level near one.
The tetrahedrons are
actually scale slower than the larger symmetry of E_11.

Subject: Polyhedra Which Tile Hyperbolic 3-Space

Which polyhedra are Vornoi cells of cosets of co-compact subgroups of

the isometries of H^3? What other polyhedra tile H^3? Is it still
open whether the Dehn invariant of any polyhedron tiling H^3 is 0?

Thanks,

Subject: Re: Polyhedra Which Tile Hyperbolic 3-Space
Which polyhedra are Vornoi cells of cosets of co-compact subgroups of
the isometries of H^3?
There is absolutely no hope of giving any reasonable kind of
answer to this question; there is a plethora of possible groups,
and each group has a continuum of orbits, which can lead to a
variety of Voronoi polyhedra.

Even in the Euclidean case, the problem is not likely to be
solved very soon, although there it's pretty obvious that the
number of combinatorial types is bounded. There is an example by
Engels of a Voronoi cell that has (I think) 38 faces.
What other polyhedra tile H^3?
This is probably even more hopeless. There are easy examples
that show that the ARE some more.
Is it still
open whether the Dehn invariant of any polyhedron tiling H^3 is 0?
I don't know, but expect so. This is not so hopeless - a
counterexample tiling must have certain slightly paradoxical
properties, and it's quite hopeful that one could use these
to disprove its existence, so proving that the invariant must be 0.
On the other hand, of course, if it needn't be, this could of course
be proved by exhibiting just one special tiling.

The paradoxical nature of the required tiling reminds me of
another problem - that of defining the density of a sphere-packing
in hyperbolic space. I have read of a "counterexample packing"
of spheres with the following properties:

i) There are two tilings T1 and T2 of the space into polyhedral
cells that each contain just one of the spheres.

ii) Each of T1 and T2 admits an automorphism group of isometries
that act transitively on its cells (so that all the cells of Ti
have the same volume, Vi).

iii) The volumes V1 and V2 are different (and both finite).

Does anyone know a reference for this?
