center of the universe

so we know (cuz the inet tells us) that the universe is expanding and it is estimated to be 13 billion or so years old.

the max distance we can see is 20 billion light years or so because of the expansion (hubble distance or whatever that is called)

so isn't it possible (no matter where we are in the universe) for us to see where the big bang originated because the maximum radius of the universe must be less than 13 billion light years?

i guess the whole 'the universe in not only expanding, its expansion is accelerating' really throws a wrench into that?
