where's the center?

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 2D surface, but in 3D 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.
Now, extend to our universe, expanding space, yadada. By analogy  remember that one?  there must be a point in some 4D space, surrounding us, which constitutes the center. So, the question is, can we 'point' to it, through some 4D mathematical abstraction, derived from our measurements?
