Default Looking into the past with a telescope

Davoud:
I can think of no reason why the Universe can't have a central region
in three-dimensional space if the Big Bang theory is correct.


Greg Neill:
If the BB is correct, then every place in the 3D universe was
once co-located with the center. So there is no unique place
that one can call The Center, since every place equally
fulfills the role.


I have seen this argument in various guises. In /my/ /mind/ it breaks
down because of mixed verb tenses. "Every place /was/ /once/ co-located
in the center." OK, but "every place" departed the center when
space-time expanded, leaving the center behind. These "places" did not
all carry the center with them so that each one is now a center of its
own. Such a place -- a region that was denser than average due to a
quantum fluctuation and later became the core of a galaxy -- may be a
local center, but it is not the Universal center -- in /my/ /mind/ .

Simple common sense says that the two-dimensional surface of a sphere
has no center -- I figured that out for myself while playing with a
solid-color, featureless rubber ball as a child -- but if you look
beyond the surface, inside the sphere, you will find a center.
