You seemed to have missed the point in the post.  Perhaps you didn't read the link to this paper that explains it. . http://www4.ncsu.edu/uni...kenny/papers/cosmo.html Go to the 3rd section of this paper; it explains the debate on infinite vs. finite universe and talks about the critical value of density that Einstein said will say whether the universe is open (infinite) or closed (finite).  You will notice that the current conclusion is that: "Right now the evidence seems to favor an infinite universe, but it is not yet conclusive."

For you to insist that the universe has an edge is a presumption.  One that has no evidence, actually.  It feels right to your way of thinking, but as I have shown you... physics is still agnostic on the issue.  The fact that the universe looks the same in every direction could mean one of a couple things.  A) That we really are at the center of a finite universe or B) That the universe is infinite whereby every point is the center.  

The fact that we can see the same distance in every direction is likely a product of the limit of our ability to see (i.e. technology).  This is borne out by the increases in what we can see every time we increase our technology.  Even with our current breed of space telescopes and the drastic improvement that has made into how far away we can see, we still see a homogeneous, isotropic universe which looks basically the same in every direction.

I put it to you that your certainty that the universe has an edge or a shape is unfounded.  It may be the case, but there is certainly no evidence to support the hypothesis... and there is clearly no information I know of that would allow one to be certain of this idea.

[We have gone rather far afield here, but that's the nature of the beast, and you did ask for this information.]
