Hmm. Not sure I'm convinced about that. There must be stars at the edge of the universe, on the cutting edge so to speak of the big bang that will have stars behind them but none in front of them in their direction of travel?It sounds like you're assuming that the big bang happened at a point in space, where stuff expanded out into a void. This isn't the accepted model; the *whole universe* was hot and dense at the big bang, and then expanded uniformly, everything flying away from everything else; it didn't expand *into* anything, it just expanded, that is, the space between stuff increased. There was no edge then and there's no edge now.
Wherever you are in the universe, everything is receding from you in all directions. What we call the 'edge' of the universe is just the limit of what we can see; we know that the whole universe is vastly bigger than that (possibly infinite).
