It has been stated time and time again that the fact that galaxies are moving away from us makes us appear to be the center of the universe. Of course, someone making this observation from a different galaxy would come to the same conclusion. The implication is that any given observer in any given galaxy will perceive the same notion of being in the center due to the universe expanding.
I can accept this to an extent, but according to Wikipedia, "The diameter of the observable universe is estimated to be about 28 billion parsecs (93 billion light-years), putting the edge of the observable universe at about 46–47 billion light-years away." Now, let's say I could somehow make an instant leap near this perceived edge; let's say I leap to 45 billion light years from here, and I observe the expansion of the universe. Would I really still be no more in the center than any other point, when I'm only a billion light years from the perceived edge? Or is it that I'm still as much in the center as any other position because the "actual" universe is apparently much larger, or even infinite?
