Congratulations on another clear and logical entry. As you mention to Georgina, it does tie into a much larger field of inquiry. It is quite breath of fresh air to read Eric Reiter's and your essay together.
I happened to be discussing the very issue on a blog devoted to Julian Barbour's work, From Time to Shape. To save scrolling through, here are some relevant passages:
"The presumption of space arising from a singularity is based on this idea that space is created by measurements of objects and actions, yet that raises the question of what and where the singularity came from. If we assume a void, ie empty space, it doesn't need a cause. Only actions require cause. Yet it has an effect, ie, equilibrium."
"I understand Euclidian space is lacking motion, measurement, etc. That's why I call it an equilibrium state. The point is that when physics tries to eliminate it, the result is a singularity, which introduces a whole range of other issues and problems, which many in the physics community seem quite content to spend their careers wrestling with. Since the resulting speculations are leading in directions that are completely untestable, I think we might consider re-evaluating space as something defined by motion and measurement, rather than created by it. The vacuum as foundational state, rather than the singularity as starting point."
"What originally led me to question cosmology and eventually a lot of current physics, was the point that according to both theory and observation, space is flat. Expansion and gravitational contraction effectively balance out on the scale we can observe. The continued argument for an expanding universe is this is just due to the enormity of the entire universe and that just as a small portion of the earth's surface appears flat, so does our observed portion of the universe. Yet it seemed a lot of excess baggage was being attached to what might well be a simple cyclical process, a universal convection cycle, if you will, where radiant energy expanding out is matched by mass falling inward. It even seemed to me this opposite curvature of the intergalactic space between the gravitational well of galaxies was the cosmological constant, balancing out gravity, as Einstein originally proposed. So effectively there are "hills" between the gravity wells, such that they sum out to flat space. Keep in mind we only see the distant light that managed to thread its way past the intervening galaxies and thus traveled this empty space.
The curvature then, is not so much due to space, but the measurement of what occupies it, with expansion as much an integral feature of radiation, as gravity is an integral feature of mass.
Black holes are not portals into some other dimension, but gravitational vortices, which eventually spin that infalling mass out as jets of cosmic rays. Given they can be observed billions of light years out, that is an enormous amount of energy being ejected and logically explains the destiny of any and all mass which fell in.
Since I see space as infinite, entropy doesn't apply, as it is a consequence of closed sets. With infinity, any energy lost to one set is replaced by energy from surrounding sets. On this infinite scale, the galaxies and all the energy are really just cosmic vacuum fluctuations.
Dark matter might be due to gravity being a consequence of radiation condensing into mass and becoming ever more dense(M=e/c2). Dark energy wouldn't be necessary, since redshift would be a lensing issue, not the actual expansion of the universe. With gravitational lensing, we know the source is not moving, only the path of the light is being contracted around the field and thus bent, with expansion, it would be an opposite effect.
The black body radiation from the edge of the visible universe, that is presumed to be residue from the Big Bang, would actually be light redshifted completely off the visible scale and I predict that when the next generation of infrared telescopes get in service, they will find features of these distant galaxies that will be too old to fit in the age limits of current theory. Quite a few have been found which already push theory to the breaking point, but no one in the business is willing to risk suggesting the problem is in the theory."
We likely discussed this last year, but I stuck it here to add fuel to the fire of a debate that needs to happen. My entry this year is on my usual obsession with our perception of the direction of time: The Problem: We See Time Backward.
Ps, The site has been losing comments, so it's best to copy your posts before sending them. I just had to rewrite this one.
