I've read the majority of your books and like them all, and I love "Fuzzy Nation".

Could there be an additional contribution from some type of yet unknown symmetry breaking?
I do not know how the critical density is calculated, I need to do some more investigating on the assumption to produce this value.

Other thoughts, I’m not sure how the extreme gravitational red shift and conservation of information might affect the density at the edge of the knowable universe.

My calculated density is 335 million times that of the critical density.
This is not a win, but it is not the end of my thought experiment.

It is the value that differentiates whether the universe will keep expanding into a “Heat death” or will eventually collapse back upon itself into the “Big Crunch”. The critical density is 9.90 * 10^-27 Kg/M^3.

3.32*10^-18 Kg/M^3
This looks reasonably low.
Researching the subject, there is a generally accepted density called the “Critical density of the universe.”

Knowing this radius and the fact that the gravitation potential increases linearly inside a sphere of uniform density, we can solve for this density. (Mean Density of the Knowable Universe)=(Speed of Light)^2*3/(8*(Gravitational Constant)*PI()*(Radius of the knowable universe)^2) =

That's a whole lot of water, but it explains the point.
If we consider the radius of the knowable universe (The radius defined by the point where the ever-increasing Doppler red shift prevents us from seeing further) is 46.5 billion light-years.

(Radius of the black hole equals (¾*PI()*(Gravitational Constant)*(material density))^0.5
A globe of Water, the Schwarzschild radius is 2.68 Astronomical Units or 4*10^11 Meters (The distance from the center of the Earth to the center of the sun).

Could the boundary conditions at the edge of the knowable universe give rise to a quantum field that would create a red shift via Einstein's field theory without a cosmological constant or dark energy?

What proves that we are just reinforcing bad assumptions? What if there is a similitude between the event horizon and the edge of the knowable universe?
