where's the center?
Posted: Jun 20, 2013 10:22 PM

An expanding balloon is the standard picture/analogy
to elucidate the expanding universe. OK, let's go
with that; an analogy ostensibly represents an ANALOG
to the subject, right?

The balloon is a 2-D surface, but in 3-D space,
there's a center. Inhabitants of Balloon World
are stuck within that surface. They cannot point
toward the center, but we can see it.

By analogy - remember that one? - there must be a
point in some 4-D space, surrounding us, which
constitutes the center. So, the question is, can
we 'point' to it, through some 4-D mathematical
abstraction, derived from our measurements?
