Another question - how can the Hubble telescope see light coming at it from 13.5 billion light years away regardless of what direction it looks in with those same points of light all originating shortly after the universe was created? Wouldn't that put us at the center of the universe? (Much as we like to think so, I doubt that we're that important.)

Google on: "center of the universe" cosmologyStart with Big Bang Cosmology Primer, from Berkeley, which offers an answer.

So your idea is?
Again, today, Oct. 6, most of this site is missing.
Any else suffering that loss?
My idea: please restore the site to its previous magnitude.
To understand the problem you must think four dimensionally. Any instant in time is a point on a four dimensional sphere, the radius of the expanding sphere is in the time dimension. Looking outward from any point in the sphere one sees surfaces at earlier points on the sphere closer towards the center which is the big bang. Any point on the surface from the point of view of the viewer at that point seems to be the center of the universe. It is an illusion.
