Isn't space curved around matter? So isn't there a limit? When you travel to the edge of the universe you cannot keep going, as space is dependent on matter. Yes that boundary will expand as the universe keeps expanding but space doesn't go on forever.
Check out the automatic link for "edge of the universe". It is a common misconception about cosmology that the universe has an edge or boundary. If you follow the link in your post they'll have something to say about it.
