The universe has no edge and no center. It has been uniformly expanding since the big bang -- but ALL OF SPACE is expanding. The big bang did not occur at some particular place. No matter where you are, you see everything moving outward from you.

This is like an incomplete math problem. Let me explain. We have to first find and "edge" and measure its distance... We have not yet found a boundary to the universe, so it is a question that can not be answered seriously, in any other way besides this.

At least from Earth The comoving distance from Earth to the edge of the visible universe (also called particle horizon) is about 14 billion parsecs (46.5 billion light-years) in any direction.[2] This defines a lower limit on the comoving radius of the observable universe, although as noted in the introduction, it's expected that the visible universe is somewhat smaller than the observable universe since we only see light from the cosmic microwave background radiation that was emitted after the time of recombination, giving us the spherical surface of last scattering (gravitational waves could theoretically allow us to observe events that occurred earlier than the time of recombination, from regions of space outside this sphere). The visible universe is thus a sphere with a diameter of about 28 billion parsecs (about 93 billion light-years). http://en.wikipedia.org/wiki/Edge_of_the_Universe
