The Earth is near the center.
One of the requirements of this creationist cosmology is that the Earth is near the center of the universe. Now this is not geocentrism because the universe is not revolving around the Earth; it is merely talking about our physical position. Such an idea, however, is consistent with observation.
It is, however, philosophically repugnant to an atheistic perspective simply because the probability would be way too small. As a result, one of the things that the Big Bang cosmology does is eliminate the idea of a center through what is erroneously called the Copernican Principle. The idea is that the universe is either infinite or that space curves back on itself in such a manner as to prevent there from being a real center. However, it puts any observer as appearing to be in the center.
What this Creationist cosmology assumes is a bounded universe where the earth is near the center. This would have effects on what we would observe in the rest of the universe due to gravitational time dilation.
The Galaxies are moving away from us.
This one is an observed fact as indicated by the redshift measured in all but the nearest of galaxies. First of all, three things can cause a redshift in galaxies. The first is simple motion through space, the second is an expansion of space and the third is gravitational redshift. The number one problem with the prospect of a gravitational red shift is that it is coming inward, not outward. Either one of the first two would be acceptable within this cosmology.
In any event, this requirement is one that is met by observation, and in fact, it was developed based on the Idea that the redshift of galaxies represents one of these two means for the universe to be expanding.
There is an edge beyond which there is no more matter.
By its very nature, a bounded universe has an edge beyond which there is no matter. So, what happens to space, you may ask. If the universe is fundamentally information, then spacetime is ultimately just a coordinate system; then it really doesn't matter, because it only exists mathematically. That said, the simple fact is that in this cosmology, there is an edge to the matter.
The edge consists of water of twice the mass of the observable universe.
The reason for this bordering material being water is what is described in Genesis chapter 1. The reason for the amount of mass results from calculations on what effect it would have on observations. This mass would have the effect of causing Earth to be time dilated as to see a small blue shift in distant galaxies. This slight blue shift would not overcome the overall expansion but simply lessen the effect of it.
Conclusion.
Here we have a cosmology based on the description in the Bible. Not only does the Bible allow for a bounded universe, but one where the Earth is physically near its center, a fact which is consistent with observation. This has observational effects on what we can expect to see, and it turns out that these observational effects do indeed exist.
