It’s a simple concept. Is there a “navel” of the universe?
If there were, could we see it?
There are a lot of theoretical physics/math surrounding this point — i.e. even if there were a “center” of the universe, which direction should we look for it?
In addition, should not space seem to be expanding in all directions.
There are conflicting observations, but it’s not clear we observe the universe moving from us in all directions (which theoretically an expanding universe from a big bang should produce).
The speculation about a empty area (e.g. a navel), could only be proven if we had sufficient resolution power to observe a vacated space, and matter going in different vectors around it.
What it seems we can observe today is the following
1) Not all parts of the universe are going away from us at the same speed
2) There is a *lot* of missing matter in the universe (dark matter) we can’t see (based on making the numbers work for the Big Bang Expansion).
Gerald L. Schroeder is an MIT Astrophysicist who has written 5-6 books on the harmony of science/scripture. I have read a few of his books. Here’s one.

He ranges from theoretical math to information theory, chaos theory, etc. a great read.
One last time, what do you believe what is behind Polaris?
