Your question seems to assume there’s an edge but there doesn’t have to be. Space could be curving in on itself (if you had FTL travel maybe you could make a circuit) or it could be infinite. What I’m not sure about is the distribution of matter in an infinite universe. Is there an edge to the matter or is it infinitely distributed with the universe itself.
