Not sure if its possible to reach the fringe of the universe. Our known universe is based on our ever expanding light horizon- the maximum distance light can travel to us since the start of the universe. If we sent a ship to the edge of that horizon we would find another light horizon of equal size and so on. I think its possible this continues on forever.
Another question to ponder is if you each the edge of matter in the universe (the "farthest star" if you will) does space just stop? Or does hard vacuum continue on forever?
