“The evidence shouts that the universe is bounded, and that its boundary forms a near perfect sphere around our approximate location.”
~~~~~~~~~~~~~~
Please cite your “evidence”.

The speed of transport of information in this universe is limited to “C” — the speed of light.
It is a simple fact that the speed of light (in a universe of sufficient age and size) always limits our observation to a space-time sphere — centered, of course, on the observer’s POV.
Your argument appears to be circular (in 4-D)...
Also, I would like to ask the writer if the observable universe is a perfect sphere around us, then isn’t it also a perfect sphere around a galaxy at the far edge of our “perfect sphere”.
So now there are 2 “perfect spheres”, the edge of the second one, we can’t possibly see, but must also contain galaxies at the distant edge of THAT “perfect sphere” which are, themselves, all centered within a “perfect sphere” of their own.
So where’s the boundary? Show me the boundary.

Right on target. That's why I specified, "...centered, of course, on the observer’s POV." (For those in Rio Linda or the YEC world, that acronym is translated, "Point Of View".)
It always amazes me that there are people who simply refuse to admit (or are incapable of comprehending) that the view of our universe from this third-rate ball of mud is infinitely far from the only one.
Sam, when you provide some shred of evidence for an unbounded universe, I will make the effort to gather the abundant evidence that demonstates a boundary.
To date, no evidence of an unbounded state has shown itself. (and an unbounded expansion is illogical without evidence that it is possible Infinity is a logical and quantitative place keeper, not a reality. )

A “wish item” for which there are no facts in evidence.
